PEC Training
Meade LX200GPS Pec Training
- Setup -> Telescope -> RA PEC -> Training
Method
- Connect to Stellarium and MaximDL
- Telescope pointed at Vega synced
- Moved to Epsilon Lyrae (epsilon_lyrae)
- Camera disconnected from MaximDL and connected to PHD Guiding
PHD Guiding keeps the star in the same position at all times allowing the PEC to be trained
Data read with PEC Editor (MyScopeShort) and saved as *.txt file for further analysis
PHD Settings
1st PEC
- RA_PEC_DATA1.TXT
- 0.2s
- Default Advanced Settings with:
- Full Frame
2nd PEC
- RA_PEC_DATA2.TXT
- 0.2s
- Default Advanced Settings but:
- Subframe
Processing Code:
- To be added
Plots for PEC Data:
Test images:
NGC6675 (Spiral Galaxy) - 1 (ngc6675_possible) and 5 min (ngc6675_definite) exposure, 2x2 Binning
M57 (Ring Nebula) - 1 min exposure, 2x2 Binning

Focus and Filters
Average filter wavelength
- Blue: 450mm
- Green: 550mm
- Red: 650mm
ST-8ME Quantum Efficiency:
- Blue: 55%
- 1.82x exposure from clear
- 60s clear -> 109s
- Green: 70%
- 1.43x exposure from clear
- 60s clear -> 86s
- Red: 75%
- 1.33x exposure from clear
- 60s clear -> 80s
Test Images
M57 - Ring Nebula
M56 - Globular Cluster
- 1x60s Luminance image
M27 - Dumbbell Nebula
- 9x60s Luminance images stacked to form a 6x60s image
- 1x109s Blue image
- 1x86s + 2x60s Green images
- 1x86s + 5x60s Red images
During the Dumbbell Nebula imaging the filters were accidentally changed due to the mouse scroll.
- Possible workarounds:
- Use autosave function to take images
- Check before taking a new single image

* [[http://iminuit.github.io/iminuit/api.html][iMinuit]]
*Performance (measured with Python %timeit() magic function):*
* PyMinuit: best of 3: 13.9 s per loop
* iMinuit: best of 3: 11 s per loop
*Conclusions:*
* iMinuit is easier to install than PyMinuit
* iMinuit is faster than PyMinuit
* iMinuit have more features than minuit (e.g. export to LaTeX and fake functions)
* Both detected and successfully minimized a 2D Gaussian on all the stars with same parameters
* PyMinuit "accidentely" fitted more Hot Pixels than iMinuit
* PyMinuit includes Simplex and Scan methods, which are not available on iMinuit
* PyMinuit is more stable - annoing bug in latest version cause segfault it limits, steps, ... are not set
Keep PyMinuit for now.

pre-requisite: have [[http://www.cygwin.com/][Cygwin]] installed and a GNU compiler.
Cygwin comes with python pre-installed, from there one can install new packages with:
* easy_install packageName
* pip install packageName
To use ==pip== you must install it first using ==easy_install pip==
The ==pip== method is favorable for it allows you to search, uninstall and upgrade packages easily.
==pip== guide:
* ==pip freeze== - display currently installed packages
* ==pip search packageName==
* ==pip install packageName [--upgrade]== - installs or upgrade an already installed package
* ==pip uninstall packageName== - uninstall a package
*Packages installed*
* ipython
* numpy
* scipy
* pyfits
*To be installed:*
* matplotlib
* opengl
* pyside
* pywin32 (don't support cygwin)
* pyminuit ([[http://code.google.com/p/pyminuit/wiki/HowToInstall][detailed guide]])
1 Download the required files: [[http://code.google.com/p/pyminuit/downloads/detail?name=Minuit-1_7_9-patch1.tar.gz][Minuit-1_7_9]] and [[http://pyminuit.googlecode.com/files/pyminuit-1.2.1.tgz][pyminuit-1.2.1]]
1 Extract and change to Minuit directory (under cygwin)
1 Compile Minuit with:
1 bash configure
make
make install
1 Change to pyminuit directory ( ==cd ../pyminuit-1.2.1== )
1 Build and install with: ==python setup.py install --with-minuit=/location/of/Minuit-1_7_9==
Abandoned. No pywin32 support, changing for full Windows python.

Ring Galaxy (NGC1291)
Protostar (IRAS 20324+4057) 
"The bizarre looking ring galaxy NGC 1291 in Eridanus.
These fairly rare types of galaxy are usually much fainter objects, but this one at "only" 33 million light years away is easily visible in modest size telescopes though the faint outer ring of material is much fainter than this.
Its strange appearance is the likely the result of a collision with another galaxy in the distant past.
20"CDK with FLI-PL6303e camera. LRGB. L: 70mins. RGB: 5/5/10mins" - Damian Peach
IRAS 20324+4057 is a Protostar in the Cygnus OB2 Association, 4,500 light-years (1,380 parsecs) away.
This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
INT: H-alpha
cyan ACS: F606W (V)
blue
ACS: F814W (I)
red

After turning telescope on, it successfully received GPS signal and did not started the usual RA movement.
The Camera was connected to Python via MaximDL
Telescope and Focuser connected to Python via the POTH Hub
Coordinates in agrement between Scope, Python and Stellarium
Target was set to be -0.1º RA from current telescope position and Python SlewToTarget was tested.
Telescope moved the right amount and stopped, both telescope and Python alerted when ready.
A second test was made with +0.5º RA. Also successfully.
Still with small (-0.1º RA/DEC and +0.5º RA) movements, Python SlewToCoordinates was tested successfully.
With the tests done, the telescope was moved to Vega via controled movements on Stellarium
Vega was inside the Camera Range, demonstrating that the Park Method works.
Vega was recentered (-0.01 on RA) and the telescope was manually synced.
During this test, movements as small as 0.003º on RA proved to have no effect whatsoever.
The next step was to test the focuser and the camera.
First, while still on continuous mode of the camera, the Python-Focuser connection was tested.
Python can read the position and move the focuser. Units are steps. 1 step = 20µm
Having confirmed that one can move the focuser with Python, Vega was taken out of focus to test if we could focus the star using a small

*Focus movements*
* Positive -> In
* Negative -> Out
*Tests*
The data below have a significant experimental error associated with the not fixed measuring equipment.
Also, they can have errors related to a possible angle between the measuring equipment and the in-out axis therefore, the real value would differ by a factor of cos(theta)
*out*
* move(-5000) - 1.86mm
* move(-5000) - 1.80mm
* move(-5000) - 1.86mm
* move(-5000) - 1.81mm
* move(-5000) - 1.88mm
* *mean = (1.842 ± 0.031)mm*
* move(-1000) - 0.31mm
* move(-1000) - 0.40mm
* move(-1000) - 0.44mm
* move(-1000) - 0.27mm
* move(-1000) - 0.45mm
* *mean = (0.378 ± 0.076)mm*
The out movement is coherent and 5000 steps is indeed equivalent to 5x1000 steps
This give 1 step aprox 0.37µm
*in*
* move(5000) - 1.52mm
* move(5000) - 1.55mm
* move(5000) - 1.52mm
* move(5000) - 1.48mm
* move(5000) - 1.57mm
* *mean = (1.528 ± 0.031)mm*
* move(1000) - 0.21mm
* move(1000) - 0.20mm
* move(1000) - 0.15mm
* move(1000) - 0.30mm
* move(1000) - 0.18mm
* *mean = (0.208 ± 0.050)mm*
The in movement is 25 to 50% smaller than the out movement (depending on the movement size) with larger movements closer to the equivalent out.
This give 1 step being between 0.2 and 0.3µm
*Conclusions*
The execution of the above movements led to the following conclusions:
* Focuser always finishes in a 'in-movement' (e.g. asking to move out will make the focuser goes more than needed and come back about 1mm)
* This causes the isMoving check to return before the focus being ready.
* Focuser limit less than aprox 30k steps when going in.
* When close to the limit, focuser will overstep (move(5000) caused the focuser to move 2.76mm)
* Focuser isn't ready when isMoving returns False.
* There's a time gap when a second comand will be accepted but not executed.

[[http://www.newastro.com/book_new/ebook/c2d.pdf][Diffraction aids]]
---------+++ Using a Bahtinov mask to find the focus:
Based on Laurie's idea and [[http://starryvistas.net/articles/focusmask/focusmask.aspx][this article]] a set of 144 images were taken.
3 images for each of the 48 moves made by the focuser. All the movements were 'in' moves of 250 steps.
The images had a 5s exposure time and a master dark (made of 10 dark) was made and reduced from the images.
On each image, a gaussian was fitted to the brightest star (142/144 success) and the amplitude and sigma median were taken for each set of 3 images per focuser position.
The data was then plotted and assumed to be in a quadratic form. The results can be seen on the images below.
For the Sigma X values, the minimum can be found at: 4841 steps
While Sigma Y minimum is at: 5411 steps
And the Amplitude maximum at: 6804 steps
According to [[LogBookAstronomyEntry0015]], the 2000 step (aprox 600µm) difference would be more than double the depth of field for the telescope [[http://starizona.com/acb/ccd/advtheoryfoc.aspx][(287µm on a f/10)]].
A visual analysis of the graphs would suggest a minimum and a maximum for Sigma Y and the Amplitude close to 6000 steps and, visually, the image at step 5750 (image set 23) is the sharpest presenting a nice 'X' diffraction pattern produced by the Bahtinov mask.

Proceeded to take another 120 dark frames at -7.5 degrees, as with coolers on 100% sensor temp would not go below -10.6 degrees.
Proceeded to take anothe 120 dark frames at -2.5 degrees.
CCD will then be reset to 0 degrees, and frames will be taken every 30 seconds as it is cooled from 0 to -10 degrees. The exposure time will be 2 seconds. Due to lack of time this will be postponed until next week.

---------+ Project meeting on 24 / 10 /2013
Present: Chris Haynes, Paul Hallam, Ryan Cheale, Dr Boogert, Professor Cowan.
Continued discussion on taking and analysis of dark frames.
Due to the dome not being cold enough during the day, it is difficult to cool the camera down to -15 or -20 celcius. Therefore, the remaining readings will be taken further into winter, when the dome is colder.
Objectives for analysis of dark frames:
* Plot a histogram of the -5°C, 60 second frame and compute the mean, median and standard deviation.
* Plot the column mean and consider the standard deviation for all columns.
* Plot the standard deviation as the square root of the mean and check to see if it's a Poisson Distribution.
Additionally, we should think about the dark current rate (the rate at which an electric current is generated in the chip due to the production of electrons and holes) and how to compensate for it.
We should also consider what the faintest star we could detect would be, looking at the point spread function of our telescope.

* Began the use of the canopy environment to begin data analysis in Python.
* Running into multiple problems with the canopy environment with plotting graphs
* Have made plots for the mean, standard deviation, max and min values of the data set T-05.0-NNN-E0600
* Struggling to create histogram plots, either the kernal or the environment tends to crash when trying to create a histogram of a single fit file
* Next steps:
* Produce median plots
* Refine code so only needs slight input alteration for other data sets
* Produce histograms and then further plots based off of the histograms
* begin analysis on cool down data.

Please edit and put your text etc. here
A study into the variation of background pixel count with temperature.
Initial CCD temperature was recorded to be 18 degrees. Coolers were turned on and CCD cooled to 0 degrees over the course of an hour, to ensure the entirety of the CCD began at zero degrees for the following study.
Coolers were then set to cool the CCD to -10 degrees, and one second exposures were to be taken every 30 seconds for one hour over this cool down period.
The data shall be saved in the following format: Cooler_Study-001E001
Also this shall also provide 29s exposures between the 1s exposures, which shall appear like this: Cooler_Study-001E029. This data will not be analysed.
When this collection of data has been finished, CCD was at a constant -10 degrees. The CCD coolers were switched off, and the CCD warmed back up to room temperature. Using the same method, one second exposures was taken every 30 seconds for one hour over this period.
The data shall be saved in the following format: Cooler_Study_2-001E001

---------+++ Telescope Set Up
* Target Delta Cephei selected using Stellarium and AAVSO catalogs
* Open shutters (ropes, pull apart, tie off ropes, motor control
* Turn power on
* Press power switch on telescope
* Removelens caps
* Point towards Vega
* Line up with finer scope
* Take continuous frames 0.1s
* Center Vega in frame
* Synchronise Vega with Maxim DL and Stellarium
---------+++ Target Information
* Pulsating Variable star, magnitude variation 3.5 - 4.4, Δm = 0.9
* Period 5.4 days
* Next maximum, 07/12/2013, 9:32
* RA: 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From simulated light curve - expected Δm(max) = 0.26, expected Δm(min) = 0.01
* From light curve of Delta Cephei, and time of next maximum, we believe the magnitude should be decreasing
* Companion star HIP 110988 used as a reference star
---------+++ Initial Observation of Delta Cephei
* Centered on Delta Cephei - did not use Stellarium as could move telescope through the pole
* Frames were taken using different filters, initial exposure times:
* No filters - 1s
* Blue filter - 10s
* Green filter - 3s
* Red filter - 3s
* Took sample frames using this-set up, max pixel count was found using Python
* Re-evaluate exposure time to ensure max pixel count was in the range 55000 - 60000
* Re-evaluated exposure times:
* Focus filter - 1.1s
* No filter - 1s
* Blue filter - 10s
* Green filter - 5.1s
* Red filter - 3.3s
* Decided to take 5 repeats for each of these, and 10 repeats for Dark and Bias frames
* Autosave feature was used to take a sample set of data
* Residual image of Star found on Dark frames - low pixel count
* Implemented a 'Trash' frame before the Dark frame to attempt to remove this -> some residual image still remained
---------+++ Observation of Delta Cephei
* Autosave feature took approximately 10 - 15 minutes to run
* Approximately three runs were taken per hour
* Delta Cephei was observed for 5 - 6 hours
---------+++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope
* Turn off camera
* Turn off telescope
* Put cover back on camera
* Close dome shutters
* Turn off PC monitors
* Turn off lights and leave dome

20140213 LN
Reasonably clear and forecast to be good. Worth a try to get some practice in.
* CCD at -15oC
* Aligned to capella - very high in sky.
* Went down from 46 to 37 DE to theta_aur as capella saturates the camera.
* Take subframes to practice focussing. Recorded 400 frames of theat_aur for analysis later. SNR is good as super bright. Peak around 30000 ADU. Jumps around A LOT so will have to align by centroid. Then can have a look at PSF.
* Exposure 0.1s
* 300 exposures recorded in 10m12s
* 400 exposures recorded in 13m37s *Sat bhatinov mask carefully on front of scope. Recorded 50 images with same setup as before. Not so clear.
* Exposure 0.5s
* Not so clear. Pattern seems very small indeed on CCD compared to internet images. Collimation is definitely poor and its windy so don't expect it to be great. Anyway, reasonably good in focus.
* Having a look at the Pleiades. Too extended to see anything nice and certainly with the seeing. The stars are very bright and the nebulosity not so, so quite hard to observe under these conditions.
* Imaged Andromeda ok. 30s exposures.

Reduced range to 19mm to 20.5mm in steps of 0.10
Reduced range further to 19.50mm to 19.80mm in steps of 0.05
*Camera Angle*
Exposure time: 0.1s; Grating distance 1.814mm; Focus distance was 19.60mm for this
Used continuous range to find staring point.
Used range of 2.50mm to 5.50mm in increments of 0.5mm to start.
Reduced range to 4.00mm to 5.00mm in steps of 0.10mm
Reduced range further to 4.45mm to 4.65mm in steps of 0.05mm
Found the best angle to be _4.60mm_
*Brightest Peak Data*
Looking through the spectrum the brightest peak, found at 4.00mm in grating micrometer.
This was saturated so the lamp was moved back by 5cm which was still saturated, then we moved it back by another 5cm which put the lamp back from the optical fibre by 25cm. This reduced saturation where refocus was done. Seemed to saturate at 50,000 confirming it was brightest peak.
Used this to check the focus and recalculate.
used a range from 19.50mm to 20.50mm in steps of 0.10mm
Found best focus distance on micrometer to be _20.10mm_

27th Oct 2014 Msc Observation.
*Begun:* 18:30
*Finished:* 22:30
Conditions: Mostly clear, a little muggy. No cloud coverage.
Begun observation session with a run down of the procedure to prepare the dome.
*Dome Procedure:*
-
Enter dome
- Close the hatch to prevent heat rising and entering the dome. The floors beneath are heated which causes a ‘chimney’ like effect if the hatch is left open as the hot air from below will rise up through it. Ideally the scope and dome should remain cool so noise due to thermal fluctuations is kept to a minimum.
- In the Maxim DL suiteconnect to the telescope. This allows control of the camera for example you can set exposure times and capture images from the program.
- Enable the CCD cooler in Maxim. This should be done ~1 hour before taking exposures. If you take observations too soon after enabling the cooler you get a ring like effect on your observations around the outer area of the frame. The ring progresses further to the sides of the frame as the CCD cools until it eventually disappears.The set-point of the cooler is set to -10 degrees celcius and the CCD itself fluctuated around this point slightly once the cooler had taken full effect.
- Untie the ropes that control the shutter of the dome. Pull on ropes to open the shutter of dome, if the shutters do not open with ease, there is a long stick with a metal prod at one end which can be used to manually push the shutters open from near the top of the dome.
- Once shutter is open, tie the ropes off again to make sure that they are kept out the way of the moving parts of the done which can rotate bothe counter and clock-wise
- Using the door on side of dome, go outside and do some preliminary naked eye observations to find an interesting object to observe (this is important for aligning the telescope as detailed later on). This allows you to plan roughly where the telescope and open shutter should be pointing to allow unrestricted viewing.
- Using the dome control unit, align the dome opening with what you want to observe.
- When finished observing, realign both the dome and telescope to their origional position. Close the dome shutters and tie up the ropes.
To begin making observations you need to align the telescope to a bright object in the sky and then enable tracking. Tracking corrects the position of the telescope relative to the sedereal motion of the stars. This is necessary because the field of view of the telescope is so narrow if it was left stationary, the object you are observing will move out of frame. To align the telescope, the first step is to identify a bright object visible to the naked eye in the nights sky. You can acess the roof from the dome via. the door on the side. Once on the roof you are able to evaluate potential targets. We identified the star Vega (25ly away, 2.1M0, alpha lyrae - the brightest star in the lyra constellation and 5th brighest in the night's sky). The star charts provided in the program stellarium coupled with manual positional measurements allow you to identify the star you are looking at with the naked eye.
Once a object in the sky has been chosen, the next step is to align the telescope to enable the activation of tracking.
- *Telescope Alignment:*
-
Use a high speed on the control paddle (speed button -> 9 is fastest, 1 is slowest on number pad) to crudely align the scope with what you want to observe using the arrow buttons. This can be done roughly by eye by lining up the two bolts on the side of the telescope with what you are looking for.
- Then use the viewfinder which has a set of crosshairs to align the scope more accurately with the object in the sky. A medium speed setting on the paddle can be used to move the scope with a greater deal of precision.
- Once the crosshairs are centred on the object you wish to view, take an exposure in the maxim DL suite. Once the image has been taken and downloaded you can adjust the scope to get the object centred in the frame. If you set maxim DL to take continuous ~1s exposures you can get a better sense of the best way to align scope and object.
- Once the scope is aligned, enable GPS lock. This continuously corrects the scope to account for the rotation of the earth. The field of view of the scope is very narrow causing the object you are observing to move through the frame if the scope remains stationary.
- Once tracking is enabled, the scope should keep the object you are trying to view in frame automatically.
- Using the control paddle, tell the telescope which star/object it is currently aligned to
- With the telescope connected to stellarium which now allows you to control the scope through the program itself. Using the star charts, you can align the scope to stars/objects shown in stelarrium. (Wait for the ‘beep’ if you move the scope in the program. The scope moves quickly at first but then makes finer corrections to ensure the scope is aligned well. The 'beep' occurs once the telescope is properly aligned, it can take some time ~20-30 secs).
- While repositioning the telescope it is important to be aware of it's orientation with respect to it's base. The telescope is capable of flipping over on itself which can cause the CCD attatchment to collide with the stand. In a situation where this may happen, power down the telescope via the power controls located on its stand immediately.
With the telescope aligned you can control where it is looking via. the stellarium program. Multiple exposures of Vega were taken at different exposure lengths using the Maxim DL program.
Using stellarium, the telescope was then trained on the open cluster M-39 in the constellation cyganus (800ly away from earth). Again took multiple exposures. The cluster is composed of a number of stars. Using the star chart in stellarrium the star patterns were compared to that shown in the exposure allowing for individual identification of the stars the cluster is made up of.
You have the ability to manually focus the telescope. If it is out of focus the exposures of stars can present as donuts (dark centres with bright outer ring) or they seem flat and blurred at it's edges. The procedue to manually focus the telescope is first to 'unlock' the mechanism. There are two dials, the shorter one can be rotated to unlock the device allowing the second longer dial to be turned focusing the telescope.
Last target of the night was the andromeda galaxy known as M-31 (as it is a messier object) and is 2.5x106 ly away from earth and the closest spiral galaxy to the milky way group. This galaxy has a mass ~ 1.5x10^12 M0. 10 exposures were taken one after the other with the intention of eventually using them to form 1 image with considerably less noise.
An interesting point to note is that movement of the atmosphere above the telescope can cause exposures to shift in and out of focus. This was made evident as during continuous exposures of M-39, the stars were alternating between being in focus and out of focus.
The exposures taken during the night of observation are attached to this post.

*Observations of the Spectrum of Betelgeuse*
Started looking at Capella. Using a small sheet of tracing paper to allign the star in the optic fibre coupling. With Capella at a high Altitude we switched to Betelgeuse as a target to make allignment easier.
Viewed Capella at
5hrs 20' 30'' RA
45deg 8' 2'' DEC
with the micrometer at Grating-4mm, Angle-3.25mm, Focus 20.2mm.
changed the RA 5'' either side to align it centrally while observing the intensity recieved.
*Betelgeuse*
Next look at Betelgeuse,
5hrs 58' 32' RA
6deg 25' 30'' DEC
Took a 30s exposure at 4mm to look at the spectrum as best as possible. Then took 60s exposures of Betelgeuse between 0mm and 10mm in steps of 0.5mm.
After Betelgeuse we briefly moved to the Orion nebula however it was too dim to observe.
*Pollux*
7hrs 46' 14'' RA
27deg 59' 18'' DEC
Again took 60s exposures from 0mm on the grating position micrometer too 10mm in steps of 0.5mm.
Laurie left at 23:00
*Castor*
7hrs 35' 22'' RA
31deg 51' 40'' DEC

Start Time: 19:00
Conditions: Slightly cloudy at start, quickly became clear around 8pm and remained clear.
Observations:
*Castor (Alpha Gem)*
Aligned to Castor, RA: 7h 34m 35.87s, Dec: 31dg 53' 17.82" Apparent Mag: 1.93
Ring visible due to cooling of CCD chip taking place.
*Near Castor*
Observed multiple stars near Castor with low magnitude (10 - 15)
No images taken.
Ring still visible.
*NGC2388*
Centred on galaxy NGC2388, Apparent Mag: 14.
NGC2388 was chosen as a target as it is known to currently contain a Supernaova of Apparent Magnitude 15. See http://www.rochesterastronomy.org/snimages/snactive.html
Supernovae: PSN J07285387+3349106, RA: 07:28:53.87, Dec: +33:49:10.6, z = 0.013790
One frame was taken at 120s exposure. Stars were cross checked with Stellarium and were found to be low magnitude (10-16). Two other galaxies were also clearly visible, NGC2385 and NGC2389. The cooling ring was still visible at the edges of the frame. This location was chosen for the target of this observation due to the number of low magnitude stars, and the presence of three galaxies.
Uploaded a frame to astrometry.net
Experimented with 180s exposure, decided to use 120s.
Stacked frames using MaximDL built in image stacker to invstigate noise reduction.
Images taken:
Data was taken in bursts of 9 images, 3 Light Frames with 120s exposure, 3 Dark Frames at 120s exposure and 3 Bias frames.
Dome was realigned every 2 bursts to ensure unobstructed view of the sky.

---------+ 2015 05 20 LN DSLR Observation
* Trying out DSLR on back of scope
* Benefit - easy live video to investigate focussing, wide field of view
---------++ 20:30 start
* Dismounted SBIG camera (in case)
* Canon DSLR bayonet adapter + BADER 2" - T/2 Nosepiece on back of micro-focuser
* Observed Moon, Venus & Jupiter during twilight ~ 21:40
* Aligned & synchronised to artturus star to the south as visible to the naked eye
* image of M3 globular cluster ~ magnitude 6 - can make out ok in photos but still blue sky background as still slightly light
* 2155
* Trial of Deep sky object - still lightish but will keep iterating over objects
* Bodes Nebula mag 6.9
* Of note is that the DSLR is slim enough for a polar flip of the mount. Haven't, but can.
* Whirlpool Galaxy
* Getting better images but can only really see core of galaxy - still to much sky glow
From images of a single bright star or say of Jupiter and it's moons, you can see what appears to be both coma and chromatic aberration. The edges of non-point like objects have an orange tinge on one side and a blueish tinge on the other. Jupiter is relatively low just now so there is a strong affect from the atmosphere / imaging but still Jupiter had an asymmetric tinge. The moons were also quite distorted. Although the 'live view' gives you some indication, it simulates the exposure settings and can distort the image a little. Best to take images directly and zoom in to compare. Not too different from live view though.
* Telescope likely needs collimation, but the trouble is finding a good enough night for to be able to observe any improvement.
Sky much darker now. While no clouds around, there is a bit of haze - can't see huge multitude of stars.
* Starting at 3845 images of great cluster in hercules.

---------++ *Before taking data*
* Time of turn on: 18.20.
* Cooler set to -7 degrees.
* Temp at -6.9 degrees at 18.30.
* Center the telescope on Vega.
* Aling the telescope to Vega. (~Mode on the controller)
* Speed 5 and later 3 on controller while focusing on Vega.
* Microfocuser used to fine focus.
* Speed 3 to place Vega in the center of the image.
---------+++ Alpha Persei Cluster (Cr 39, Mel 20)
* We chose our cluster as the Alpha Persei cluster.
* To focus on the cluster we chose a nearby bright star Mirphak.
* We used it to correct our ofocusing and we synched Stellarium wityh the telescope.
* We choice a patch of the cluster (HIP16001) and took 10 vimages of 10 second exposures. ( x binning set to 1, x anmd y originally inverted, this was reversed)
* 5 bias frames and dark frames of 5 1min exposure.
* Took 3 40 s red.
* Took 3 40-s gtreen.
* Took 3 90 s blue.
*
* Move to a different patch (around RA:3h29min29s, DEC:49deg44'16")
* Ian joined us at 20:00
* 3 images of 60s visual.
* 3 images of 120s red.
* 3 images of 120s green.
* Finished taking data at 8.30 pm.
---------+++ Dark and bias frames
* Started taking dark frames. 5 images of 120s.
* Take 10 bias aswell.
Observation finished at 8.56pm.

The aim of the session was to modify the parameters of the camera. Using only OpenCv it was impossible to set the camera's parameters with known units.
py-ic-imaging-control was downloaded from: https://github.com/morefigs/py-ic-imaging-control
py-ic-imaging-control is a python wrapper for the IC imaging control software development kit from the imaging source (TIS). It provides control to TIS cameras, and can serve as an alternative to using OpenCv to access the cameras parameters.

The DMK camera was fixed to a tripod and pointed at the moon.
Run1: Gain set to 180 and images were recorded of the moon at a frame rate of 7.5 frames per second. The algorithm left the exposure setting on 1 as the image was not over or under exposed on this setting.
Run2: Gain was increased to 1023. The images were over exposed and the algorithm accounted for this by changing the exposure setting in increments of 1. It was noted that this was very slow to respond to large and sudden changes in conditions.
Run3: The code was modified such that the amount the algorithm changed the exposure setting depended on the number of pixels that were saturated. This massively decreased the time the algorithm took to find the correct exposure setting. See screen shot.
Images were also taken of Orion's Nebula, see image file names for parameter settings.

Az/Alt: 318deg 44'20''/38deg34'50''
Took testing pictures: Cooling_1 and cooling_2, can be seen a ring surrounded by the ice. Secong image shows larger ring, meaning hte camera is cooling down
Cooling_3 image is clear and even
Checked the wether with met office, clouds are exopected to clear for the rest of the night
Finding the star by eye, alighning the tescope, using stllarium found it was Procyon
As it wasn't clear that the star is Procyon, checked with Rigel
Took images of the delta cep with no filter and with filters: red, green, blue and spectroscope. Aimed for 50 000 pixel value - the closest to the maximum possible p.v.
Exposure time was increased as different filters were applied, because different filters obsurb more light.
Cloudy weather led to taking many pictures for blue filter with longer exp time, 16 sec.

Please edit and put your text etc. here
---------+ Finding focus of optical fibre
* The focus of the optical fibre was found by taking a relative distance between the lens and the position of the optical fibre, and measuring the amplitude of a spectral line from the laser found at 3.5mm.
* taken at 1mm intervals between 230m and 270mm.
* Fit with hyperbolae as approximation
* distance measured with ruler so very approximate i.e ±1mm
* Best focus was found at 250mm±2mm
* Iris was almost closed as the laser would saturate camera at shortest exposure.
* also took more data as SBIG ST-7E was cooling.
* Just need extra part to connect firewire camera, so that the alignment can be competed.

Please edit and put your text etc. here
---------+ Focussing Beam Splitter
* To find best focus should be able to focus onto a single fibre, once one illuminated, in focus. will have to use extension rings for optical fibre.
* CCD camera can then be adjusted until in focus.
* Focus by shifting backwards and forwards on rails.
* Find focus of camera with max intensity and minimum width of laser.
* Use diffuser or neutral density filter, will need neutral density filter.
* Make two plots of intensity on camera and fiber and adjust until peaks overlap.
* Such that there are two plots which look similar to:
---------+ Aligning Beam Splitter
* Align by moving the mirror horizontally and vertically until maximum intensity
* possibly get 3 more irises, to control aperture at camera, fibre and entry, to make sure always have good alignment.
* As now in focus, can scan around fibres and find the relative positions compared to the end where they are arranged into line.
* This could help with finding best position of ray on camera
* Look up mirror and see how much change in angle before lost fibre, one full turn until laser out of view.
* try to get two irises as far away from each other for best alignment.
* once part for CCD arrives, move around and find relative positions on camera to positions on optical fibre.
---------+ Relating to telescope
* Have to use larger beam size so that f# is the same as the telescope, f# = 10,
* currently 3 dioptre lens, so 1/3 m focal length, this means need a beam diameter of 33.3 mm or a longer focal length.
* as 
, where f is the focal length, d is the diameter of beam or aperture and f# is the f number.
* consider which camera to be used.
* beam splitter reflects 30% and transmits 70% so check this.
---------+ testing intensity
* tested the intensity at reflection and transmission, with diffuser and tissue in front of laser, tissue made intensity vary substantially so averaged over five frames, the reflection intensity was found to be 3% of the transmission intensity, however there could be problems with focus and alignment at the refection, need better analysis of this.

---------+ Aligning Camera and optical fiber
* Spectrum images,
* Exposure: 0.1s
* Temp: 10 deg
* used subframes around spectral to speed up
* FireWire camera * Exposure: 1/500 s
* The FireWire camera was attached to the beam splitter and connected to IC capture
* Optical fiber was attached using a spacer to approximate the same focal length as the FireWire CCD
* Initially an approximate focus was found on the FireWire camera.
* Then the angle of the mirror was adjusted vertically such that the laser beam was scanned vertically.
* images of the position on the CCD and the spectrum were taken at a range of positions.
* The amplitude of the spectral line was then recorded with position on the CCD.
* This gave a plot shown below for the maximum intensity. i.e centre of fiber
*
* This was then repeated for a scan horizontally, which gave the plot below.
* The best positions were found to be at [190,218] pixels, i.e 190 pixels across and 218 pixels down
* The the focus of the image was to be found.
* The box which the beam splitter and camera is attached to was placed on the rails and scanned backwards and forwards using a ruler for approximate focal length.
* Images were recorded for both the camera and optical fiber, and the amplitudes were plotted against focal length.

Please edit and put your text etc. here
---------+ Alignment of Camera and Optical Fiber
* SBIG camera,
* Temp: 10deg
* Exposure: 0.1s
* subframe around fibers
* FireWire Camera,
* Exposure: 1/500 s
* Took focus measurements first by moving beam splitter to find best focus.
* Best focus was found by subtraction background of spectral line image and summing pixels
* Best focus for image was found by finding max pixel value
*
* The optical fiber focussed ~6mm from the FireWire camera
* Optical fiber was adjusted such that it is as far out as possible using the smallest spacer, and the camera was adjusted so that it was as close to the beam splitter as possible.
* This was to close the 6mm gap found earlier
* The fiber and camera were then realigned as the FireWire camera will have been rotated slightly and moved out of alignment.
* Both horizontal and vertical alignment were used and the best positions were found at maximum intensity the same as for the focus.
*
---------+ Attachment of guidescope
* Two mounts for the dovetail plates attached on the top of telescope, plate then attached.
* The two dovetail plate mounts for the bottom of the telescope have to have small section removed due to bolts on the telescope which were in the way.
* Bottom dovetail plate then attached.
* guidescope rings and guidescope attached to the top plate
* counterweight attached to bottom.
* The telescope was then approximately balanced by adjusting the counterweights position on the plate and by unscrewing the counterweights so they were further from the OTA.

---------+ Alignment of fiber horizontally and vertically
* SBIG camera for spectrometer:
* Exposure: 0.1s
* Temp: 10 deg
* Subframes
* FireWire Camera:
* records video at 30fps
* Exposure: 1/500 s
* Approximate focus was first found. set at 255 mm
* The mirror was adjusted horizontally such that the laser moved horizontally in the camera frame.
* Images were then taken of both the spectral line of the laser and the image on the FireWire camera as it was scanned, 40 images were taken.
* The maximum intensity of the beam and its position were recorded on the FireWire camera and the summed intensity was recorded for the spectrum with removal of backgorund.
* The intensity on the spectral line was then plotted against the position on the FireWire camera, this gave a plot shown below.
* The peak position on the above plot is then used to set the position of the beam on the camera, which is approximately at a position of 200 pixels.
* Once the position has been set the process was repeated scanning this time vertically, this gave a plot as shown below.
* The best position for the beam to be on the camera for max intensity at this stage is then at pixel values [200,216].
---------+ Focussing the beam
* Once the beam has been set to the best position as found earlier the camera and optical fiber were adjusted between distances of 220mm-290mm in 2mm intervals to find the best focus.
* Here the same measurements as before were made. The intensity of the spectral line and the maximum intensity of the FireWire camera are plotted against focal distance.
* The plot of both the camera and optical fiber is shown below.
* With this image the approximate best focus was set at 250mm
---------+ Repeat of alignment
* The alignment process was then repeated as before, this gave the below plots.
* These gave maxima at a pixel position of [201,217], The image below shows the position of the laser of the camera at this point:
---------+ Horizontal Scans at different Focal lengths
* For 6 different focal lengths, 240,244,248,252,256,260, a horizontal scan of the laser was recored on the camera and the spectrometer. This range was chosen as in the above focus plots, this is where the intensity flattens.
* For each of these the position of the laser of the FireWire camera was plotted against the total intensity of the fibers.
* The aim was that the focal length which gives the smallest width of a spectral line is the correct focus.
* The plot below shows the intensity plot for each of the focal lengths, and the widths of the line.
* This shows the widths does not change much in that range, this could be due to the fact that the focus is smaller than the size of the optical fiber, therefore, the integrated amplitude will remain the same in this range.
* Therefore, by selecting a single fiber to integrate the intensity over, it should be possible to find focus.
* The below plot shows the same results for a single fiber
* This shows that the width of the line drops in the range of 252-256 mm .
* by fitting a Gaussian function to both the image on the firewire camera and the plots above, the widths could be plotted against the focal length for both.
* Each of these were then fit with a hyperbola function,
* This gave parameters of,
| parameter | FireWire | Fiber |
| mean | 254.8±1.2 | 255.2±1.1 |
| a | 4.28±0.92 | 6.12±1.25 |

Saqib Hussain + Jervis Ong Arrived at 16:24, weather clear
* AA arrived 17:30
* Took example flats with both cameras
* Setup telescope, synched on Vega
* focused the telescope on a star
* took a few dark frames to distinguish dust on the telescope
* Primary observation target identified : rho Cyg- 73 Cyg - HIG 106481, right ascension = 21h 33m 58.85298s, declination = 45° 35′ 29.1 "
* Checked the camera cooler temperatures: -5.2 for ST8 and -15.0 for ST8300
* Took exposures with exposure time 0.1s for ST8300 and 0.5s for ST8
* For ST8300, file names begin with odd alphabets (a,c and so on) whereas for ST8 file names begin with even alphabets
* The data is compiled as below:
| Telescope | Exposure time/s | Time frame/minutes | No.of Images | File starts with |
| ST8300 | 0.1 | 12 | 66 | a |
| ST8 | 0.5 | 12 | 45 | b |
| ST8300 | 0.1 | 16 | 100 | c |
| ST8 | 0.5 | 11 | 45 | d |
| ST8300 | 0.1 | 9 | 45 | e |
| ST8 | 0.5 | | 45 | f |
* Moved on to collate data for atmospheric extinction
* For ST8, we tried to take images with different filters (luminescence, red, green, blue) for an exposure time of 0.4s
* However, due to technical problems we were unable to take images with colour filters
* We continued taking unfiltered images every 10 minutes (as the star moved from the azimuth to the horizon), saving them as files beginning with L
* Exposure time is 0.5s for every image
* Cooling power was within the range of 40 and 49%
* Data are as follows:
| Time | File Name |
| 2158 | L1 |
| 2208 | L2 |
| 2218 | L3 |
| 2228 | L4 |
| 2238 | L5 |
| 2248 | L6 |
| 2258 | L7 |
| 2308 | L8 |
| 2318 | L9 |
| 2328 | L10 |
| 2338 | L11 |
* took a photo of Andromeda
* Turned the coolers off, disconnected the cameras. Double checked everything was disconnected.
* Exported data into USB stick.

set up procedure
* check for damages on solar filters
* solar fillters on finders scope and main scope
* mount camrea
* use a SCT connector
* screw onto fliter and telescop
* RGB filter
* clip onto tube
* C-mount to 1.25 inch tube
* screw onto camera
* camera
* mount camera unto telescope by unscrewing the big ccd camera
* fire wire cable connected to the camera(clips in)
* with them, covered you can open the dome doors
* switch on telescope
things differe form a normal observation:
* use different type of camera( imaging source dmk 21af04.as)
* use a different piece of software
* stop the tracking
IC capture
* open IC capture
* click camear being used
* device properties click off auto gain and exposure
* check if histogram isnt saturated
* adjust exposure so it is not saturated
* saving sequnece of image
* capture -> squence settings
* file name and target, pick a directory(desktop/data/YYYYMMDD) -> index at 1
* file type BMP
* Automated sequence -> interval at 1 sec -> end sequence after 400 Frames
* capture -> sequence timer -> start timer
how to turn off tracking
* set up -> enter
* targets -> enter
* trestral or astonamical ->enter
we are going to be using 2016-11-02 data

time: 17:22 arrived in dome. ENK JT AS AC AA
remove rain cover from telescope
open doors of dome (ropes(tie up), bolts)
go onto roof and observe sky
select Capella(HIP 24608) on Stellarium
RA/Dec 5h17m57.85s / 46deg 00' 40.4''
h(capella) = LST(egham) - \alpha = 1h41m52.8s(egham) - 5h17m57.85s(capella) =-3h36m5.05s
rotate dome to correct direction
callibrate telescope - move telescope manually to point at Capella, it can then know its position on the night sky and be moved using the stellarium programme
first take caps off telescope, turn telescope on(make sure everything is plugged in and switched on,checking all leads and sockets)
telescope automatically moves towards the west)
centre capella in finder scope(scope speed 5)
Synchronise coordinates on Capella ( object -> star -> named -> Capella -> Enter (2 seconds) -> Enter to sync)
move telescope away from capella
use the go-to key to get back to capella
Move to almaaz(HIP 23416) using the hipparcus catalogue method outlined in the script
Use Hip method again to move to Betelgeuse (HIP 27989), and bellatrix (HIP 25336)
open MaxIm DL Pro 5
exposure 1 sec start poor out of focus picture
change exposure to 0.1 sec, X bin 4 continuously taking images
use knobs on scope to unlock mirror and change the focal length, simultaneously slowly moving scope to get the star in the centre of the field of view of the CCD
get star in and out of focus and take picture
calibrate telescope to set on aldebaran
use focus (4 on pad) to get good focus with microfocuser that changes the camera not the mirror
take images in different exposuresmove to fainter section of sky, star cluster near aldebaran cluster 2 shows fringe from coolingtake 10 images to find saturation around 65000 for this CCD
move to 02 Tau and found bleeding and saturation at 10s, took multiple images at different exp times (1x1 binning)
found that simple auto dark callibration was on contiunued with this then took one without this

time 10:30am arrived in dome. A Cozens, L Lenz D Bedingham S Boogert
poor weather conitions so no solar data could be recorded
used SLR camera to take images of boiler house in order to understand how the manual settings of the camera affect images
took 30 images with different exposure times and varying the ISO number, as ISO increases smaller exposure times are required so not to saturate the image.
The images are located
C:\users\astrodome\desktop\3_data\20171018_Solar
with two files showing the dark frame images taken to show the noise of the camera with the cap on the lens and light brick images taken at different exposure times with different ISO

10:30 dome. Bedingham, Cozens, Lenz
* good weather => took a few images with Canon SLR camera
* The following settings received best results: ISO=100, exposure time=1/4s to 1/8s, max. f-number
* Used rawkit Python package to transform .cr2 files into .tiff
* Applied Hough transformation to find circles in image
* Measured brick width L with ruler and received distance D from dome to boiler house brick via Google Maps
=> L = 22cm, D=104m
* From this calculated angle to be θ = 2*arctan((L/2)/D) = 0.117° = 0.22x(angular separation of sun(0.5°))
* Next steps: - take image of smooth white background to measure the vignetting effect of camera
- adjust parameters of Hough transformation to find correct circle

Time 10:30am-1pm in dome, A Cozens, L Lenz, D Bedingham, S Boogert
Weather cloudy, intermittently clear
use DSLR to take white images to look at the natural vignetting effects of the camera, took many exposure times so to get an unsaturated image. Need to process these to get a pixel vs intensity curve to show that the fractional ratio of intensity does not depend on exposure. Also look at different colour channels and create a plot to show all 3
Then set up the telescope so as to record data, fit with sun filters and imaging source camera. Using ICcapture software.
Use shadow of the telescope to align, and adjust further with finder scope.
set telescope to the west of the sun to see it passing through the window, takes around 1min to fully pass no data recorded
Use DSLR to take images of the sun, lowering the exposure times to find an unsaturated image. Use circle finder code to analyse the intensity array across a diameter of the sun.
Attached Text files show the image numbers on the DSLR for varying exposure times ISO=100 for targets of the sun then a white light source evenly lit for investigating the vignetting effect.

* cloudy weather => took no images of Sun
* Vignetting images from last week were not symmetric
=> will have to retake those images with diffuse light (outside) and a variety of exposure times to achieve different max/min intensity values,
the ratio of I_max/I_min should be approx the same throughout
Next steps:
* Take correct vignetting images with different exposure times and diffuse light
* Analyse new vignetting images and apply curve fitting to it => V(x) => can receive real intensity with I(x)*V_max/V(x)
* Estimate unscattered intensity f of Sun images
* Fit curve to unscattered intensity => Gaußian fit => should get data back (~Gaußian curve)
* Optimise f

2: No Filter Gain 180, Exp 1/250s, no auto corrections
3: refocus camera retake no filter G 180 E 1/250
4: Blue Filter G180 E1/7s every other image goes dark then light? unsure why as no auto settings --> NT look at thisEDIT try taking longer images of a couple seconds etc in order to see if the effect is still there
5:Green Filter G180 E 1/19s filter is very dirty
6: Red Filter G180 E 1/38s good set

Time in dome: 10:00 A Cozens, L Lenz, D Bedingham, S Boogert
looking into error in blue filter images taken previously
is an error in the programme with the readout, reboots and restarts did not solve this. Updated the verison of IC Capture from 2015 model to 2017, this had some minimal effect
Look at changing the Frames Per Second to a smaller amount (from 30 to 3.75) this did correct for the oscillation problem looking at blue sky
Move to try and take images of sun again with filter
Wait for sun to be away from tree.

Weather Conditions: Clear
Time: 22:40 - 1:50
Targets: Betelgeuse & Pleiades Cluster in RBG filters
Cameras Used: SBIG ST 8XME(camera 1) and SBIG ST-8300M(camera 2)
Both cooled to -20deg
Telescope already synchronised, moved and focused on Betelgeuse. Target too bright for filters. Kept saturating.
Moved to a new target, the star, Bellatrix. Again too bright for filters.
Moved to another new target, HIP26594. 15 images taken for all three filters RBG, exposure time 1.5s.
Then moved to the Pleiades, in narrow view camera (camera 1). We took ten images in each filter with exposure time 10s. And we took ten images in each of the green and blue filters with exposure time 40s.
We switched to camera 2, a wide view that could take an image of the whole cluster. The image is inverted in camera 2. We took 20 images with exposure time 0.4s with no filter.

* Attached cameras: make sure plugged in switched on
* Cameras: SBIG ST8-XME (main scope LX200(bottom one)), SBIG-ST8300M(monochromatic)
* Star Alignement: on remote: Mode --, use arrows to move telescope until can see star over top of barrel without seeing barrel. Target: Betelgeuse, speed 9
* generated Maxim dl, connected both cameras, set exposure time to 0.1s
* set to speed 5, center
* start exposure, bin 4, continuous, center object, speed 3
* adjust focus, unlock primary mirror clockwise 2 revolutions, bracketing process(see how the object is changing), object keeps moving, brightness changes, focus as much as possible, center it again speed 3, synchronize-object,star,named, click for 2 sec
* observede diffraction pattern- something is wrong with the camera, filter plate not moving, adjusting, fixed filter changing
* change exposure time to 0.3s, get star off center, focus on other, dimmer stars, adjust focus once more to see clearly
* discovered diffraction pattern in filter image
* took apart camera with help of Prof Boogert
* once camera filter in working condition, resumed observation
* took exposures of far field stars near Betelgeuse in order to focus the telescope
* shifted focus to plaidees - Atlas and Cleo
* used Astrometry in order to determine our location in the night sky
* once Atlas and Cleo found, took 0.1 interval exposures from 1 to 5 seconds until stars were saturating pixel value
* once pixel values saturated, shifted view to m41 orions nebula
* took one 7 second exposure
* ended observation around 20:25

15/2/18 Began: 17:30
Started up telescope & opened observatory. Connected to camera with maximdl (disabled camera 2), turned on cooler to -15.
Found Capella @ LST=3:45, h= 22:27, rotated telescope mount. Changed declination to 46 degrees. Located star in viewfinder.
Began continuous 0.1s 4x4 binning image capture of CCD view. Moved telescope (speed 1) opposite to image view due to CCD being upside down, to centre Capella.
Go-to button used, caused telescope to move way off target. Recallibrating as a result. Now LST=4:15, so h = 22:57, relocated Capella. Centered etc.
With LST 4:27, Atlas found at h=0:32. dec 24 deg 6 min.
Used astrometry.net to work out stars from unknown image 1, located area in stellarium
Moved to bright stars (i.e atlas and pleione), checked again with astrometry and stellarium. Synced to Pleione HIP 17851 SAO 76229 on both telescope and stellarium (connected to telescope)
Centred on Pleione. Tested stellarium movement to other stars.
Centred on Atlas, took multiple images at several exposure times, saturating the image individually for both bright stars.
zeroed telescope, closed up dome.
Finished 20:00

Logbook for PH3010 Solar limb darkening mini-project, initial setup meeting
Present: DB, MA, JC, HS
Order of tasks for observation of the sun:
1) DO NOT STARE DIRECTLY AT SUN. DO NOT POINT UNPROTECTED TELESCOPE AT SUN
2) Go outside dome and check that sun will not be obscured by the tree, wind thingy. If it will be, will have to wait before able to take images of sun
3) Check solar filters are not damaged. Fit solar filters to main scope (and if using finder scope, fit solar filter to that). Fit CCTV lens to camera, camera to filters, filters to telescope.
4) Open dome, move opening so that allows shadow of telescope to be seen on dome wall
5) Use the shadow of the top scope (the one secured by two sets of three prongs) to align the telescope with the sun. When the shadows from both sets of prongs overlap, the telescope is (roughly) aligned with the sun
6) If using finder scope, use to target edge of sun.
7) Use IC Capture program to view camera feed (really need to jam the cable into the back of the camera to get the pc to detect it). In device-properties can control gain and exposure settings
8) Use live camera feed to target edge of sun and focus (unlock and use know on back of telescope)
9) Change declination of telescope and monitor live camera feed. Need to find centre-line of sun. This is when any change in declination results in the suns edge moving out of frame (away from centre, only changing declination in one direction will move it out of frame - the other will move it more in frame)
10) On telescope control setup-targets-terrestrial or astronomical
terrestrial will keep telescope at fixed angle, astronomical follows objects through the sky
11) Choose filter to image with. Point telescope as closely as possible to centre of sun and view image histogram. Adjust and exposure until the image is not fully saturating (has a narrow yellow bar - the zero readings - visible) but has as full a range of values as practical.
12) Return telescope to point at edge of sun, in the centre. In IC capture go to the timed capture settings. Choose an appropriate target folder and image capture filenames, set the image type to bmp, turn the 'auto display capture' to off and set an appropriate capture interval and number of captures.
Note: Sun subtends an angle of about 0.5 degrees. Previous years have taken 405 seconds worth of images for this project.
13) capture images. Repeat step 11 onwards for another filter

* Dome entered 10am. Present: MA, JC, HS, supervised by Dr. DB
* Telescope cover removed, solar filters put on
* camera and colour filters were already attached to telescope. setup checked just to be sure
* Telescope setup reviewed+approved by DB
* Dome doors opened, telescope turned on
* Moon was still visible in sky - dome doors moved to allow viewing of it
* Moon used for focus (coarse and fine), took a couple of images of nice craters
* Moon found by (roughly) lining it up with the telescope, then with the finder scope, then with the camera image
* Dome doors moved to allow viewing of sun, telescope slewed to find sun
* telescope shadow aligned on wall behind telescope
* telescope moved to bring the two rows of knobs into alignment (i.e. telescope pointing at sun)
* Using camera feed, approximate equator of sun found at one edge
* Test images taken
* Moon and test sun images stored in focus_images folder
* Colour image sets taken.
* All image sets performed by pointing telescope ahead of suns motion and switching to terrestrial mode - motion of sun across sky then carries sun across the frame of view.
* All image sets taken over 3 minutes 10 seconds. This time determined by timing a test run of the method.
* 1 image per second taken for the length of the image set.
* Used maximum gain for all image sets. Exposure determined by manually slewing across the sun and trialling different exposures. Aim was to get as close to having maximum pixel values in the image, without actually having any maxed out pixels
* Where necessary, solar eclipse glasses were used to directly view sun e.g. to determine if clouds were obstructing the sun, or just the area around it
* Clear Filter 1:
* Gain 799, exposure 1/1000 seconds
* trees obstructing parts of image set - produces obvious errors in dataset
* Clear Filter 2:
* Gain 1023, exposure 1/4000 seconds
* Blue Filter 1
* Gain 1023, exposure 1/154 seconds
* Some obstruction of sun by clouds
* Blue Filter 2
* Gain 1023, exposure 1/154 seconds
* Still some clouds, but far fewer than with Blue Filter 1
* Green Filter 1
* Gain 1023, exposure 1/308 seconds
* Lots of clouds
* Green 2
* Gain 1023, exposure 1/308 seconds
* Even more clouds
* Red 1
* Gain 1023, exposure 1/1241 seconds
* A few false starts (so the file indexing is messed up), but managed to get a good run of images
* Was not able to perform another run with the green filter, due to increasing cloud cover
* Dome doors repositioned above door to roof and closed.
* Solar filter removed and lens cap replaced. Filter stored back in its home.
* Telescope returned to 0h0d
* NOTE: Minor mix-up with imgae file names. All image sets are stored in the appropriate folders / .zips for the colour filter used, but the some image sets use the wrong colour name in the individual image filenames. Recommend handling image sets carefully / renaming appropriately when used.

* Present JC, AD
* Began cooling at 16:45 to -12 deg C (~90%)
* Filter wheel set to Clear, Red, Green, Blue
* Centred on Capella and took GPS-fix. Encountered problem: telescope believed it was -1h RA from Capella however this offset was constant.
* Edit: This seemed to just be an issue with the coordinates read-out on the paddle.
* Centred on M35 and took 1000x0.1s exposures to focus.
* Then took 60s exposure- significant effects of moonlight on image- change target to M36 (RA/DEC: 05 37 13.8/34 09 04)
* Light pollution significantly reduced suggesting moon was indeed the source.
* took 60s and 90s exp in all filters
* moved to (RA/DEC: 05 37 31/34 07 50) and repeated.
* took dark and bias frames before finishing observation at 9:30pm.

PEC Training
Meade LX200GPS Pec Training
- Setup -> Telescope -> RA PEC -> Training
Method
- Connect to Stellarium and MaximDL
- Telescope pointed at Vega synced
- Moved to Epsilon Lyrae (epsilon_lyrae)
- Camera disconnected from MaximDL and connected to PHD Guiding
PHD Guiding keeps the star in the same position at all times allowing the PEC to be trained
Data read with PEC Editor (MyScopeShort) and saved as *.txt file for further analysis
PHD Settings
1st PEC
- RA_PEC_DATA1.TXT
- 0.2s
- Default Advanced Settings with:
- Full Frame
2nd PEC
- RA_PEC_DATA2.TXT
- 0.2s
- Default Advanced Settings but:
- Subframe
Processing Code:
- To be added
Plots for PEC Data:
Test images:
NGC6675 (Spiral Galaxy) - 1 (ngc6675_possible) and 5 min (ngc6675_definite) exposure, 2x2 Binning

Focus and Filters
Average filter wavelength
- Blue: 450mm
- Green: 550mm
- Red: 650mm
ST-8ME Quantum Efficiency:
- Blue: 55%
- 1.82x exposure from clear
- 60s clear -> 109s
- Green: 70%
- 1.43x exposure from clear
- 60s clear -> 86s
- Red: 75%
- 1.33x exposure from clear
- 60s clear -> 80s
Test Images
M57 - Ring Nebula
M56 - Globular Cluster
- 1x60s Luminance image
M27 - Dumbbell Nebula
- 9x60s Luminance images stacked to form a 6x60s image
- 1x109s Blue image
- 1x86s + 2x60s Green images
- 1x86s + 5x60s Red images
During the Dumbbell Nebula imaging the filters were accidentally changed due to the mouse scroll.
- Possible workarounds:
- Use autosave function to take images
- Check before taking a new single image

APIs:
* [[http://seal.web.cern.ch/seal/documents/minuit/mnusersguide.pdf][Seal Minuit]]
* [[http://iminuit.github.io/iminuit/api.html][iMinuit]]
*Performance (measured with Python %timeit() magic function):*
* PyMinuit: best of 3: 13.9 s per loop
* iMinuit: best of 3: 11 s per loop
*Conclusions:*
* iMinuit is easier to install than PyMinuit
* iMinuit is faster than PyMinuit
* iMinuit have more features than minuit (e.g. export to LaTeX and fake functions)
* Both detected and successfully minimized a 2D Gaussian on all the stars with same parameters
* PyMinuit "accidentely" fitted more Hot Pixels than iMinuit
* PyMinuit includes Simplex and Scan methods, which are not available on iMinuit
* PyMinuit is more stable - annoing bug in latest version cause segfault it limits, steps, ... are not set
Keep PyMinuit for now.

| Created: 10 Sep 2013 16:48:33 | Last Revised: 11 Sep 2013 15:49:16 | Public.PedroPaiva | Building Python on cygwin |
pre-requisite: have [[http://www.cygwin.com/][Cygwin]] installed and a GNU compiler.
Cygwin comes with python pre-installed, from there one can install new packages with:
* easy_install packageName
* pip install packageName
To use ==pip== you must install it first using ==easy_install pip==
The ==pip== method is favorable for it allows you to search, uninstall and upgrade packages easily.
==pip== guide:
* ==pip freeze== - display currently installed packages
* ==pip search packageName==
* ==pip install packageName [--upgrade]== - installs or upgrade an already installed package
* ==pip uninstall packageName== - uninstall a package
*Packages installed*
* ipython
* numpy
* scipy
* pyfits
*To be installed:*
* matplotlib
* opengl
* pyside
* pywin32 (don't support cygwin)
* pyminuit ([[http://code.google.com/p/pyminuit/wiki/HowToInstall][detailed guide]])
1 Download the required files: [[http://code.google.com/p/pyminuit/downloads/detail?name=Minuit-1_7_9-patch1.tar.gz][Minuit-1_7_9]] and [[http://pyminuit.googlecode.com/files/pyminuit-1.2.1.tgz][pyminuit-1.2.1]]
1 Extract and change to Minuit directory (under cygwin)
1 Compile Minuit with:
1 bash configure
make
make install
1 Change to pyminuit directory ( ==cd ../pyminuit-1.2.1== )
1 Build and install with: ==python setup.py install --with-minuit=/location/of/Minuit-1_7_9==

Ring Galaxy (NGC1291)
Protostar (IRAS 20324+4057) "The bizarre looking ring galaxy NGC 1291 in Eridanus.
These fairly rare types of galaxy are usually much fainter objects, but this one at "only" 33 million light years away is easily visible in modest size telescopes though the faint outer ring of material is much fainter than this.
Its strange appearance is the likely the result of a collision with another galaxy in the distant past.
20"CDK with FLI-PL6303e camera. LRGB. L: 70mins. RGB: 5/5/10mins" - Damian Peach
IRAS 20324+4057 is a Protostar in the Cygnus OB2 Association, 4,500 light-years (1,380 parsecs) away.
This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
INT: H-alpha
cyan ACS: F606W (V)

After turning telescope on, it successfully received GPS signal and did not started the usual RA movement.
The Camera was connected to Python via MaximDL
Telescope and Focuser connected to Python via the POTH Hub
Coordinates in agrement between Scope, Python and Stellarium
Target was set to be -0.1º RA from current telescope position and Python SlewToTarget was tested.
Telescope moved the right amount and stopped, both telescope and Python alerted when ready.
A second test was made with +0.5º RA. Also successfully.
Still with small (-0.1º RA/DEC and +0.5º RA) movements, Python SlewToCoordinates was tested successfully.
With the tests done, the telescope was moved to Vega via controled movements on Stellarium
Vega was inside the Camera Range, demonstrating that the Park Method works.
Vega was recentered (-0.01 on RA) and the telescope was manually synced.
During this test, movements as small as 0.003º on RA proved to have no effect whatsoever.
The next step was to test the focuser and the camera.
First, while still on continuous mode of the camera, the Python-Focuser connection was tested.
Python can read the position and move the focuser. Units are steps. 1 step = 20µm
Having confirmed that one can move the focuser with Python, Vega was taken out of focus to test if we could focus the star using a small

prin = True

POTHFocuser.Move(step)
while POTHFocuser.IsMoving:
if not prin:

*Focus movements*
* Positive -> In
* Negative -> Out
*Tests*
The data below have a significant experimental error associated with the not fixed measuring equipment.
Also, they can have errors related to a possible angle between the measuring equipment and the in-out axis therefore, the real value would differ by a factor of cos(theta)
*out*
* move(-5000) - 1.86mm
* move(-5000) - 1.80mm
* move(-5000) - 1.86mm
* move(-5000) - 1.81mm
* move(-5000) - 1.88mm
* *mean = (1.842 ± 0.031)mm*
* move(-1000) - 0.31mm
* move(-1000) - 0.40mm
* move(-1000) - 0.44mm
* move(-1000) - 0.27mm
* move(-1000) - 0.45mm
* *mean = (0.378 ± 0.076)mm*
The out movement is coherent and 5000 steps is indeed equivalent to 5x1000 steps
This give 1 step aprox 0.37µm
*in*
* move(5000) - 1.52mm
* move(5000) - 1.55mm
* move(5000) - 1.52mm
* move(5000) - 1.48mm
* move(5000) - 1.57mm
* *mean = (1.528 ± 0.031)mm*
* move(1000) - 0.21mm
* move(1000) - 0.20mm
* move(1000) - 0.15mm
* move(1000) - 0.30mm
* move(1000) - 0.18mm
* *mean = (0.208 ± 0.050)mm*
The in movement is 25 to 50% smaller than the out movement (depending on the movement size) with larger movements closer to the equivalent out.
This give 1 step being between 0.2 and 0.3µm
*Conclusions*
The execution of the above movements led to the following conclusions:
* Focuser always finishes in a 'in-movement' (e.g. asking to move out will make the focuser goes more than needed and come back about 1mm)
* This causes the isMoving check to return before the focus being ready.
* Focuser limit less than aprox 30k steps when going in.
* When close to the limit, focuser will overstep (move(5000) caused the focuser to move 2.76mm)
* Focuser isn't ready when isMoving returns False.
* There's a time gap when a second comand will be accepted but not executed.

[[http://www.newastro.com/book_new/ebook/c2d.pdf][Diffraction aids]]
---------+++ Using a Bahtinov mask to find the focus:
Based on Laurie's idea and [[http://starryvistas.net/articles/focusmask/focusmask.aspx][this article]] a set of 144 images were taken.
3 images for each of the 48 moves made by the focuser. All the movements were 'in' moves of 250 steps.
The images had a 5s exposure time and a master dark (made of 10 dark) was made and reduced from the images.
On each image, a gaussian was fitted to the brightest star (142/144 success) and the amplitude and sigma median were taken for each set of 3 images per focuser position.
The data was then plotted and assumed to be in a quadratic form. The results can be seen on the images below.
For the Sigma X values, the minimum can be found at: 4841 steps
While Sigma Y minimum is at: 5411 steps
And the Amplitude maximum at: 6804 steps
According to [[LogBookAstronomyEntry0015]], the 2000 step (aprox 600µm) difference would be more than double the depth of field for the telescope [[http://starizona.com/acb/ccd/advtheoryfoc.aspx][(287µm on a f/10)]].
A visual analysis of the graphs would suggest a minimum and a maximum for Sigma Y and the Amplitude close to 6000 steps and, visually, the image at step 5750 (image set 23) is the sharpest presenting a nice 'X' diffraction pattern produced by the Bahtinov mask.

* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* Attempted Installation of Python Canopy on personal laptop to begin data analysis but fails to install on Windows 8.0 (Attempting update to 8.1 to see if it rectifies issue) [Installed 32 bit version instead]
* Set temperature value to -07.5 deg C, left for 30 - 40 mins to stabalise.
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* For data analysis will need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.

Using Autosave feature to speed up process, Hence file format has changed to: T-10.0-001-E0001
Must go back to data taken on the 18/10/2013 and rename files for consistancy -> Done.
Proceeded to take another 120 dark frames at -7.5 degrees, as with coolers on 100% sensor temp would not go below -10.6 degrees.
Proceeded to take anothe 120 dark frames at -2.5 degrees.
CCD will then be reset to 0 degrees, and frames will be taken every 30 seconds as it is cooled from 0 to -10 degrees. The exposure time will be 2 seconds. Due to lack of time this will be postponed until next week.

---------+ Project meeting on 24 / 10 /2013
Present: Chris Haynes, Paul Hallam, Ryan Cheale, Dr Boogert, Professor Cowan.
Continued discussion on taking and analysis of dark frames.
Due to the dome not being cold enough during the day, it is difficult to cool the camera down to -15 or -20 celcius. Therefore, the remaining readings will be taken further into winter, when the dome is colder.
Objectives for analysis of dark frames:
* Plot a histogram of the -5°C, 60 second frame and compute the mean, median and standard deviation.
* Plot the column mean and consider the standard deviation for all columns.
* Plot the standard deviation as the square root of the mean and check to see if it's a Poisson Distribution.
Additionally, we should think about the dark current rate (the rate at which an electric current is generated in the chip due to the production of electrons and holes) and how to compensate for it.
We should also consider what the faintest star we could detect would be, looking at the point spread function of our telescope.

---------+++ Activity Log
* Took off cover for telescope & Camera
* Turned on Camera and followed steps detailed [[Students.UnderGraduates.RyanChealeCameraTechnicalAspects][here]]
* Set temperature to -10 deg C, waited 30 - 40 mins for stable temperature
* Used Autosave Sequence located at 'Desktop/Data/20131016_RC/25darks60s.seq'
* Autosave feature allows running of each permutation whilst saving automatically
* Format T-tt.t - NNN - Eeeee.fit where T - temperature, t - temperature value, N - repetition (==20) , E - Exposure, e- Exposure time value (0.1s, 1s, 5s, 10s, 60s, 180s)
* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* turned off the coolers on the camera to allow it to reutn to room temperature.
* Proceeded to take data in 30s intervals for 30mins whilst turning the coolers back on and allowing the temperature to reduce to -10 deg C to see what effects allowing the temperature to stabalise has
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* For data analysis still need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.
Python
* Began the use of the canopy environment to begin data analysis in Python.
* Running into multiple problems with the canopy environment with plotting graphs
* Have made plots for the mean, standard deviation, max and min values of the data set T-05.0-NNN-E0600
* Struggling to create histogram plots, either the kernal or the environment tends to crash when trying to create a histogram of a single fit file
* Next steps:
* Produce median plots
* Refine code so only needs slight input alteration for other data sets
* Produce histograms and then further plots based off of the histograms
* begin analysis on cool down data.

A study into the variation of background pixel count with temperature.
Initial CCD temperature was recorded to be 18 degrees. Coolers were turned on and CCD cooled to 0 degrees over the course of an hour, to ensure the entirety of the CCD began at zero degrees for the following study.
Coolers were then set to cool the CCD to -10 degrees, and one second exposures were to be taken every 30 seconds for one hour over this cool down period.
The data shall be saved in the following format: Cooler_Study-001E001
Also this shall also provide 29s exposures between the 1s exposures, which shall appear like this: Cooler_Study-001E029. This data will not be analysed.
When this collection of data has been finished, CCD was at a constant -10 degrees. The CCD coolers were switched off, and the CCD warmed back up to room temperature. Using the same method, one second exposures was taken every 30 seconds for one hour over this period.
The data shall be saved in the following format: Cooler_Study_2-001E001
Again this will also produce data that will not be analysed, in the form of: Cooler_Study_2-001E029
Room temperature in this case is 25.6 degrees.

---------+++ Telescope Set Up
* Target Delta Cephei selected using Stellarium and AAVSO catalogs
* Open shutters (ropes, pull apart, tie off ropes, motor control
* Turn power on
* Press power switch on telescope
* Removelens caps
* Point towards Vega
* Line up with finer scope
* Take continuous frames 0.1s
* Center Vega in frame
* Synchronise Vega with Maxim DL and Stellarium
---------+++ Target Information
* Pulsating Variable star, magnitude variation 3.5 - 4.4, Δm = 0.9
* Period 5.4 days
* Next maximum, 07/12/2013, 9:32
* RA: 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From simulated light curve - expected Δm(max) = 0.26, expected Δm(min) = 0.01
* From light curve of Delta Cephei, and time of next maximum, we believe the magnitude should be decreasing
* Companion star HIP 110988 used as a reference star
---------+++ Initial Observation of Delta Cephei
* Centered on Delta Cephei - did not use Stellarium as could move telescope through the pole
* Frames were taken using different filters, initial exposure times:
* No filters - 1s
* Blue filter - 10s
* Green filter - 3s
* Red filter - 3s
* Took sample frames using this-set up, max pixel count was found using Python
* Re-evaluate exposure time to ensure max pixel count was in the range 55000 - 60000
* Re-evaluated exposure times:
* Focus filter - 1.1s
* No filter - 1s
* Blue filter - 10s
* Green filter - 5.1s
* Red filter - 3.3s
* Decided to take 5 repeats for each of these, and 10 repeats for Dark and Bias frames
* Autosave feature was used to take a sample set of data
* Residual image of Star found on Dark frames - low pixel count
* Implemented a 'Trash' frame before the Dark frame to attempt to remove this -> some residual image still remained
---------+++ Observation of Delta Cephei
* Autosave feature took approximately 10 - 15 minutes to run
* Approximately three runs were taken per hour
* Delta Cephei was observed for 5 - 6 hours
---------+++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope
* Turn off camera
* Turn off telescope
* Put cover back on camera
* Close dome shutters
* Turn off PC monitors
* Turn off lights and leave dome

20140213 LN
Reasonably clear and forecast to be good. Worth a try to get some practice in.
* CCD at -15oC
* Aligned to capella - very high in sky.
* Went down from 46 to 37 DE to theta_aur as capella saturates the camera.
* Take subframes to practice focussing. Recorded 400 frames of theat_aur for analysis later. SNR is good as super bright. Peak around 30000 ADU. Jumps around A LOT so will have to align by centroid. Then can have a look at PSF.
* Exposure 0.1s
* 300 exposures recorded in 10m12s
* 400 exposures recorded in 13m37s *Sat bhatinov mask carefully on front of scope. Recorded 50 images with same setup as before. Not so clear.
* Exposure 0.5s
* Not so clear. Pattern seems very small indeed on CCD compared to internet images. Collimation is definitely poor and its windy so don't expect it to be great. Anyway, reasonably good in focus.
* Having a look at the Pleiades. Too extended to see anything nice and certainly with the seeing. The stars are very bright and the nebulosity not so, so quite hard to observe under these conditions.
* Imaged Andromeda ok. 30s exposures.

Using the spectrometer to find the brightest spectral line in mercury and Find the best micrometer reading for the angle of the camera.
Camera was ST-7E, Setup SBIG Universal.
Temperature for all the images was -6.5 deg C.
*Focus*
Exposure time: 0.1s; Grating distance 1.814mm; Camera angle micrometer reading 2.495 (heavily sloped)
Used continuous range to find a reasonable staring point.
Used range of 18mm to 20.5 mm in steps of 0.5
Reduced range to 19mm to 20.5mm in steps of 0.10
Reduced range further to 19.50mm to 19.80mm in steps of 0.05
*Camera Angle*
Exposure time: 0.1s; Grating distance 1.814mm; Focus distance was 19.60mm for this
Used continuous range to find staring point.
Used range of 2.50mm to 5.50mm in increments of 0.5mm to start.
Reduced range to 4.00mm to 5.00mm in steps of 0.10mm
Reduced range further to 4.45mm to 4.65mm in steps of 0.05mm
Found the best angle to be _4.60mm_
*Brightest Peak Data*
Looking through the spectrum the brightest peak, found at 4.00mm in grating micrometer.
This was saturated so the lamp was moved back by 5cm which was still saturated, then we moved it back by another 5cm which put the lamp back from the optical fibre by 25cm. This reduced saturation where refocus was done. Seemed to saturate at 50,000 confirming it was brightest peak.
Used this to check the focus and recalculate.
used a range from 19.50mm to 20.50mm in steps of 0.10mm
Found best focus distance on micrometer to be _20.10mm_

27th Oct 2014 Msc Observation.
*Begun:* 18:30
*Finished:* 22:30
Conditions: Mostly clear, a little muggy. No cloud coverage.
Begun observation session with a run down of the procedure to prepare the dome.
*Dome Procedure:*
-
Enter dome
- Close the hatch to prevent heat rising and entering the dome. The floors beneath are heated which causes a ‘chimney’ like effect if the hatch is left open as the hot air from below will rise up through it. Ideally the scope and dome should remain cool so noise due to thermal fluctuations is kept to a minimum.
- In the Maxim DL suiteconnect to the telescope. This allows control of the camera for example you can set exposure times and capture images from the program.
- Enable the CCD cooler in Maxim. This should be done ~1 hour before taking exposures. If you take observations too soon after enabling the cooler you get a ring like effect on your observations around the outer area of the frame. The ring progresses further to the sides of the frame as the CCD cools until it eventually disappears.The set-point of the cooler is set to -10 degrees celcius and the CCD itself fluctuated around this point slightly once the cooler had taken full effect.
- Untie the ropes that control the shutter of the dome. Pull on ropes to open the shutter of dome, if the shutters do not open with ease, there is a long stick with a metal prod at one end which can be used to manually push the shutters open from near the top of the dome.
- Once shutter is open, tie the ropes off again to make sure that they are kept out the way of the moving parts of the done which can rotate bothe counter and clock-wise
- Using the door on side of dome, go outside and do some preliminary naked eye observations to find an interesting object to observe (this is important for aligning the telescope as detailed later on). This allows you to plan roughly where the telescope and open shutter should be pointing to allow unrestricted viewing.
- Using the dome control unit, align the dome opening with what you want to observe.
- When finished observing, realign both the dome and telescope to their origional position. Close the dome shutters and tie up the ropes.
To begin making observations you need to align the telescope to a bright object in the sky and then enable tracking. Tracking corrects the position of the telescope relative to the sedereal motion of the stars. This is necessary because the field of view of the telescope is so narrow if it was left stationary, the object you are observing will move out of frame. To align the telescope, the first step is to identify a bright object visible to the naked eye in the nights sky. You can acess the roof from the dome via. the door on the side. Once on the roof you are able to evaluate potential targets. We identified the star Vega (25ly away, 2.1M0, alpha lyrae - the brightest star in the lyra constellation and 5th brighest in the night's sky). The star charts provided in the program stellarium coupled with manual positional measurements allow you to identify the star you are looking at with the naked eye.
Once a object in the sky has been chosen, the next step is to align the telescope to enable the activation of tracking.
- *Telescope Alignment:*
-
Use a high speed on the control paddle (speed button -> 9 is fastest, 1 is slowest on number pad) to crudely align the scope with what you want to observe using the arrow buttons. This can be done roughly by eye by lining up the two bolts on the side of the telescope with what you are looking for.
- Then use the viewfinder which has a set of crosshairs to align the scope more accurately with the object in the sky. A medium speed setting on the paddle can be used to move the scope with a greater deal of precision.
- Once the crosshairs are centred on the object you wish to view, take an exposure in the maxim DL suite. Once the image has been taken and downloaded you can adjust the scope to get the object centred in the frame. If you set maxim DL to take continuous ~1s exposures you can get a better sense of the best way to align scope and object.
- Once the scope is aligned, enable GPS lock. This continuously corrects the scope to account for the rotation of the earth. The field of view of the scope is very narrow causing the object you are observing to move through the frame if the scope remains stationary.
- Once tracking is enabled, the scope should keep the object you are trying to view in frame automatically.
- Using the control paddle, tell the telescope which star/object it is currently aligned to
- With the telescope connected to stellarium which now allows you to control the scope through the program itself. Using the star charts, you can align the scope to stars/objects shown in stelarrium. (Wait for the ‘beep’ if you move the scope in the program. The scope moves quickly at first but then makes finer corrections to ensure the scope is aligned well. The 'beep' occurs once the telescope is properly aligned, it can take some time ~20-30 secs).
- While repositioning the telescope it is important to be aware of it's orientation with respect to it's base. The telescope is capable of flipping over on itself which can cause the CCD attatchment to collide with the stand. In a situation where this may happen, power down the telescope via the power controls located on its stand immediately.
With the telescope aligned you can control where it is looking via. the stellarium program. Multiple exposures of Vega were taken at different exposure lengths using the Maxim DL program.
Using stellarium, the telescope was then trained on the open cluster M-39 in the constellation cyganus (800ly away from earth). Again took multiple exposures. The cluster is composed of a number of stars. Using the star chart in stellarrium the star patterns were compared to that shown in the exposure allowing for individual identification of the stars the cluster is made up of.
You have the ability to manually focus the telescope. If it is out of focus the exposures of stars can present as donuts (dark centres with bright outer ring) or they seem flat and blurred at it's edges. The procedue to manually focus the telescope is first to 'unlock' the mechanism. There are two dials, the shorter one can be rotated to unlock the device allowing the second longer dial to be turned focusing the telescope.
Last target of the night was the andromeda galaxy known as M-31 (as it is a messier object) and is 2.5x106 ly away from earth and the closest spiral galaxy to the milky way group. This galaxy has a mass ~ 1.5x10^12 M0. 10 exposures were taken one after the other with the intention of eventually using them to form 1 image with considerably less noise.
An interesting point to note is that movement of the atmosphere above the telescope can cause exposures to shift in and out of focus. This was made evident as during continuous exposures of M-39, the stars were alternating between being in focus and out of focus.
The exposures taken during the night of observation are attached to this post.

*Observations of the Spectrum of Betelgeuse*
Started looking at Capella. Using a small sheet of tracing paper to allign the star in the optic fibre coupling. With Capella at a high Altitude we switched to Betelgeuse as a target to make allignment easier.
Viewed Capella at
5hrs 20' 30'' RA
45deg 8' 2'' DEC
with the micrometer at Grating-4mm, Angle-3.25mm, Focus 20.2mm.
changed the RA 5'' either side to align it centrally while observing the intensity recieved.
*Betelgeuse*
Next look at Betelgeuse,
5hrs 58' 32' RA
6deg 25' 30'' DEC
Took a 30s exposure at 4mm to look at the spectrum as best as possible. Then took 60s exposures of Betelgeuse between 0mm and 10mm in steps of 0.5mm.
After Betelgeuse we briefly moved to the Orion nebula however it was too dim to observe.
*Pollux*
7hrs 46' 14'' RA
27deg 59' 18'' DEC
Again took 60s exposures from 0mm on the grating position micrometer too 10mm in steps of 0.5mm.
Laurie left at 23:00
*Castor*
7hrs 35' 22'' RA

Please edit and put your text etc. here
Start Time: 19:00
Conditions: Slightly cloudy at start, quickly became clear around 8pm and remained clear.
Observations:
*Castor (Alpha Gem)*
Aligned to Castor, RA: 7h 34m 35.87s, Dec: 31dg 53' 17.82" Apparent Mag: 1.93
Ring visible due to cooling of CCD chip taking place.
*Near Castor*
Observed multiple stars near Castor with low magnitude (10 - 15)
No images taken.
Ring still visible.
*NGC2388*
Centred on galaxy NGC2388, Apparent Mag: 14.
NGC2388 was chosen as a target as it is known to currently contain a Supernaova of Apparent Magnitude 15. See http://www.rochesterastronomy.org/snimages/snactive.html
Supernovae: PSN J07285387+3349106, RA: 07:28:53.87, Dec: +33:49:10.6, z = 0.013790
One frame was taken at 120s exposure. Stars were cross checked with Stellarium and were found to be low magnitude (10-16). Two other galaxies were also clearly visible, NGC2385 and NGC2389. The cooling ring was still visible at the edges of the frame. This location was chosen for the target of this observation due to the number of low magnitude stars, and the presence of three galaxies.
Uploaded a frame to astrometry.net
Experimented with 180s exposure, decided to use 120s.
Stacked frames using MaximDL built in image stacker to invstigate noise reduction.
Images taken:
Data was taken in bursts of 9 images, 3 Light Frames with 120s exposure, 3 Dark Frames at 120s exposure and 3 Bias frames.
Dome was realigned every 2 bursts to ensure unobstructed view of the sky.

---------+ 2015 05 20 LN DSLR Observation
* Trying out DSLR on back of scope
* Benefit - easy live video to investigate focussing, wide field of view
---------++ 20:30 start
* Dismounted SBIG camera (in case)
* Canon DSLR bayonet adapter + BADER 2" - T/2 Nosepiece on back of micro-focuser
* Observed Moon, Venus & Jupiter during twilight ~ 21:40
* Aligned & synchronised to artturus star to the south as visible to the naked eye
* image of M3 globular cluster ~ magnitude 6 - can make out ok in photos but still blue sky background as still slightly light
* 2155
* Trial of Deep sky object - still lightish but will keep iterating over objects
* Bodes Nebula mag 6.9
* Of note is that the DSLR is slim enough for a polar flip of the mount. Haven't, but can.
* Whirlpool Galaxy
* Getting better images but can only really see core of galaxy - still to much sky glow
From images of a single bright star or say of Jupiter and it's moons, you can see what appears to be both coma and chromatic aberration. The edges of non-point like objects have an orange tinge on one side and a blueish tinge on the other. Jupiter is relatively low just now so there is a strong affect from the atmosphere / imaging but still Jupiter had an asymmetric tinge. The moons were also quite distorted. Although the 'live view' gives you some indication, it simulates the exposure settings and can distort the image a little. Best to take images directly and zoom in to compare. Not too different from live view though.
* Telescope likely needs collimation, but the trouble is finding a good enough night for to be able to observe any improvement.
Sky much darker now. While no clouds around, there is a bit of haze - can't see huge multitude of stars.
* Starting at 3845 images of great cluster in hercules.
Finish at 22:20

---------++ *Before taking data*
* Time of turn on: 18.20.
* Cooler set to -7 degrees.
* Temp at -6.9 degrees at 18.30.
* Center the telescope on Vega.
* Aling the telescope to Vega. (~Mode on the controller)
* Speed 5 and later 3 on controller while focusing on Vega.
* Microfocuser used to fine focus.
* Speed 3 to place Vega in the center of the image.
---------+++ Alpha Persei Cluster (Cr 39, Mel 20)
* We chose our cluster as the Alpha Persei cluster.
* To focus on the cluster we chose a nearby bright star Mirphak.
* We used it to correct our ofocusing and we synched Stellarium wityh the telescope.
* We choice a patch of the cluster (HIP16001) and took 10 vimages of 10 second exposures. ( x binning set to 1, x anmd y originally inverted, this was reversed)
* 5 bias frames and dark frames of 5 1min exposure.
* Took 3 40 s red.
* Took 3 40-s gtreen.
* Took 3 90 s blue.
*
* Move to a different patch (around RA:3h29min29s, DEC:49deg44'16")
* Ian joined us at 20:00
* 3 images of 60s visual.
* 3 images of 120s red.
* 3 images of 120s green.
* Finished taking data at 8.30 pm.
---------+++ Dark and bias frames
* Started taking dark frames. 5 images of 120s.
* Take 10 bias aswell.
Observation finished at 8.56pm.

The aim of the session was to modify the parameters of the camera. Using only OpenCv it was impossible to set the camera's parameters with known units.
py-ic-imaging-control was downloaded from: https://github.com/morefigs/py-ic-imaging-control
py-ic-imaging-control is a python wrapper for the IC imaging control software development kit from the imaging source (TIS). It provides control to TIS cameras, and can serve as an alternative to using OpenCv to access the cameras parameters.

The DMK camera was fixed to a tripod and pointed at the moon.
Run1: Gain set to 180 and images were recorded of the moon at a frame rate of 7.5 frames per second. The algorithm left the exposure setting on 1 as the image was not over or under exposed on this setting.
Run2: Gain was increased to 1023. The images were over exposed and the algorithm accounted for this by changing the exposure setting in increments of 1. It was noted that this was very slow to respond to large and sudden changes in conditions.
Run3: The code was modified such that the amount the algorithm changed the exposure setting depended on the number of pixels that were saturated. This massively decreased the time the algorithm took to find the correct exposure setting. See screen shot.
Images were also taken of Orion's Nebula, see image file names for parameter settings.

Az/Alt: 318deg 44'20''/38deg34'50''
Took testing pictures: Cooling_1 and cooling_2, can be seen a ring surrounded by the ice. Secong image shows larger ring, meaning hte camera is cooling down
Cooling_3 image is clear and even
Checked the wether with met office, clouds are exopected to clear for the rest of the night
Finding the star by eye, alighning the tescope, using stllarium found it was Procyon
As it wasn't clear that the star is Procyon, checked with Rigel
Took images of the delta cep with no filter and with filters: red, green, blue and spectroscope. Aimed for 50 000 pixel value - the closest to the maximum possible p.v.
Exposure time was increased as different filters were applied, because different filters obsurb more light.
Cloudy weather led to taking many pictures for blue filter with longer exp time, 16 sec.

Please edit and put your text etc. here
---------+ Finding focus of optical fibre
* The focus of the optical fibre was found by taking a relative distance between the lens and the position of the optical fibre, and measuring the amplitude of a spectral line from the laser found at 3.5mm.
* taken at 1mm intervals between 230m and 270mm.
* Fit with hyperbolae as approximation
* distance measured with ruler so very approximate i.e ±1mm
* Best focus was found at 250mm±2mm
* Iris was almost closed as the laser would saturate camera at shortest exposure.
* also took more data as SBIG ST-7E was cooling.
* Just need extra part to connect firewire camera, so that the alignment can be competed.

Please edit and put your text etc. here
---------+ Focussing Beam Splitter
* To find best focus should be able to focus onto a single fibre, once one illuminated, in focus. will have to use extension rings for optical fibre.
* CCD camera can then be adjusted until in focus.
* Focus by shifting backwards and forwards on rails.
* Find focus of camera with max intensity and minimum width of laser.
* Use diffuser or neutral density filter, will need neutral density filter.
* Make two plots of intensity on camera and fiber and adjust until peaks overlap.
* Such that there are two plots which look similar to:
---------+ Aligning Beam Splitter
* Align by moving the mirror horizontally and vertically until maximum intensity
* possibly get 3 more irises, to control aperture at camera, fibre and entry, to make sure always have good alignment.
* As now in focus, can scan around fibres and find the relative positions compared to the end where they are arranged into line.
* This could help with finding best position of ray on camera
* Look up mirror and see how much change in angle before lost fibre, one full turn until laser out of view.
* try to get two irises as far away from each other for best alignment.
* once part for CCD arrives, move around and find relative positions on camera to positions on optical fibre.
---------+ Relating to telescope
* Have to use larger beam size so that f# is the same as the telescope, f# = 10,
* currently 3 dioptre lens, so 1/3 m focal length, this means need a beam diameter of 33.3 mm or a longer focal length.
* as , where f is the focal length, d is the diameter of beam or aperture and f# is the f number.
* consider which camera to be used.
* beam splitter reflects 30% and transmits 70% so check this.
---------+ testing intensity
* tested the intensity at reflection and transmission, with diffuser and tissue in front of laser, tissue made intensity vary substantially so averaged over five frames, the reflection intensity was found to be 3% of the transmission intensity, however there could be problems with focus and alignment at the refection, need better analysis of this.

---------+ Aligning Camera and optical fiber
* Spectrum images,
* Exposure: 0.1s
* Temp: 10 deg
* used subframes around spectral to speed up
* FireWire camera * Exposure: 1/500 s
* The FireWire camera was attached to the beam splitter and connected to IC capture
* Optical fiber was attached using a spacer to approximate the same focal length as the FireWire CCD
* Initially an approximate focus was found on the FireWire camera.
* Then the angle of the mirror was adjusted vertically such that the laser beam was scanned vertically.
* images of the position on the CCD and the spectrum were taken at a range of positions.
* The amplitude of the spectral line was then recorded with position on the CCD.
* This gave a plot shown below for the maximum intensity. i.e centre of fiber
*
* This was then repeated for a scan horizontally, which gave the plot below.
* The best positions were found to be at [190,218] pixels, i.e 190 pixels across and 218 pixels down
* The the focus of the image was to be found.
* The box which the beam splitter and camera is attached to was placed on the rails and scanned backwards and forwards using a ruler for approximate focal length.
* Images were recorded for both the camera and optical fiber, and the amplitudes were plotted against focal length.

Please edit and put your text etc. here
---------+ Alignment of Camera and Optical Fiber
* SBIG camera,
* Temp: 10deg
* Exposure: 0.1s
* subframe around fibers
* FireWire Camera,
* Exposure: 1/500 s
* Took focus measurements first by moving beam splitter to find best focus.
* Best focus was found by subtraction background of spectral line image and summing pixels
* Best focus for image was found by finding max pixel value
*
* The optical fiber focussed ~6mm from the FireWire camera
* Optical fiber was adjusted such that it is as far out as possible using the smallest spacer, and the camera was adjusted so that it was as close to the beam splitter as possible.
* This was to close the 6mm gap found earlier
* The fiber and camera were then realigned as the FireWire camera will have been rotated slightly and moved out of alignment.
* Both horizontal and vertical alignment were used and the best positions were found at maximum intensity the same as for the focus.
*
---------+ Attachment of guidescope
* Two mounts for the dovetail plates attached on the top of telescope, plate then attached.
* The two dovetail plate mounts for the bottom of the telescope have to have small section removed due to bolts on the telescope which were in the way.
* Bottom dovetail plate then attached.
* guidescope rings and guidescope attached to the top plate
* counterweight attached to bottom.
* The telescope was then approximately balanced by adjusting the counterweights position on the plate and by unscrewing the counterweights so they were further from the OTA.

Please edit and put your text etc. here
---------+ Alignment of fiber horizontally and vertically
* SBIG camera for spectrometer:
* Exposure: 0.1s
* Temp: 10 deg
* Subframes
* FireWire Camera:
* records video at 30fps
* Exposure: 1/500 s
* Approximate focus was first found. set at 255 mm
* The mirror was adjusted horizontally such that the laser moved horizontally in the camera frame.
* Images were then taken of both the spectral line of the laser and the image on the FireWire camera as it was scanned, 40 images were taken.
* The maximum intensity of the beam and its position were recorded on the FireWire camera and the summed intensity was recorded for the spectrum with removal of backgorund.
* The intensity on the spectral line was then plotted against the position on the FireWire camera, this gave a plot shown below.
* The peak position on the above plot is then used to set the position of the beam on the camera, which is approximately at a position of 200 pixels.
* Once the position has been set the process was repeated scanning this time vertically, this gave a plot as shown below.
* The best position for the beam to be on the camera for max intensity at this stage is then at pixel values [200,216].
---------+ Focussing the beam
* Once the beam has been set to the best position as found earlier the camera and optical fiber were adjusted between distances of 220mm-290mm in 2mm intervals to find the best focus.
* Here the same measurements as before were made. The intensity of the spectral line and the maximum intensity of the FireWire camera are plotted against focal distance.
* The plot of both the camera and optical fiber is shown below.
* With this image the approximate best focus was set at 250mm
---------+ Repeat of alignment
* The alignment process was then repeated as before, this gave the below plots.
* These gave maxima at a pixel position of [201,217], The image below shows the position of the laser of the camera at this point:
---------+ Horizontal Scans at different Focal lengths
* For 6 different focal lengths, 240,244,248,252,256,260, a horizontal scan of the laser was recored on the camera and the spectrometer. This range was chosen as in the above focus plots, this is where the intensity flattens.
* For each of these the position of the laser of the FireWire camera was plotted against the total intensity of the fibers.
* The aim was that the focal length which gives the smallest width of a spectral line is the correct focus.
* The plot below shows the intensity plot for each of the focal lengths, and the widths of the line.
* This shows the widths does not change much in that range, this could be due to the fact that the focus is smaller than the size of the optical fiber, therefore, the integrated amplitude will remain the same in this range.
* Therefore, by selecting a single fiber to integrate the intensity over, it should be possible to find focus.
* The below plot shows the same results for a single fiber
* This shows that the width of the line drops in the range of 252-256 mm .
* by fitting a Gaussian function to both the image on the firewire camera and the plots above, the widths could be plotted against the focal length for both.
* Each of these were then fit with a hyperbola function,
* This gave parameters of,
| parameter | FireWire | Fiber |
| mean | 254.8±1.2 | 255.2±1.1 |
| a | 4.28±0.92 | 6.12±1.25 |

Saqib Hussain + Jervis Ong Arrived at 16:24, weather clear
* AA arrived 17:30
* Took example flats with both cameras
* Setup telescope, synched on Vega
* focused the telescope on a star
* took a few dark frames to distinguish dust on the telescope
* Primary observation target identified : rho Cyg- 73 Cyg - HIG 106481, right ascension = 21h 33m 58.85298s, declination = 45° 35′ 29.1 "
* Checked the camera cooler temperatures: -5.2 for ST8 and -15.0 for ST8300
* Took exposures with exposure time 0.1s for ST8300 and 0.5s for ST8
* For ST8300, file names begin with odd alphabets (a,c and so on) whereas for ST8 file names begin with even alphabets
* The data is compiled as below:
| Telescope | Exposure time/s | Time frame/minutes | No.of Images | File starts with |
| ST8300 | 0.1 | 12 | 66 | a |
| ST8 | 0.5 | 12 | 45 | b |
| ST8300 | 0.1 | 16 | 100 | c |
| ST8 | 0.5 | 11 | 45 | d |
| ST8300 | 0.1 | 9 | 45 | e |
| ST8 | 0.5 | | 45 | f |
* Moved on to collate data for atmospheric extinction
* For ST8, we tried to take images with different filters (luminescence, red, green, blue) for an exposure time of 0.4s
* However, due to technical problems we were unable to take images with colour filters
* We continued taking unfiltered images every 10 minutes (as the star moved from the azimuth to the horizon), saving them as files beginning with L
* Exposure time is 0.5s for every image
* Cooling power was within the range of 40 and 49%
* Data are as follows:
| Time | File Name |
| 2158 | L1 |
| 2208 | L2 |
| 2218 | L3 |
| 2228 | L4 |
| 2238 | L5 |
| 2248 | L6 |
| 2258 | L7 |
| 2308 | L8 |
| 2318 | L9 |
| 2328 | L10 |
| 2338 | L11 |
* took a photo of Andromeda
* Turned the coolers off, disconnected the cameras. Double checked everything was disconnected.
* Exported data into USB stick.

set up procedure
* check for damages on solar filters
* solar fillters on finders scope and main scope
* mount camrea
* use a SCT connector
* screw onto fliter and telescop
* RGB filter
* clip onto tube
* C-mount to 1.25 inch tube
* screw onto camera
* camera
* mount camera unto telescope by unscrewing the big ccd camera
* fire wire cable connected to the camera(clips in)
* with them, covered you can open the dome doors
* switch on telescope
things differe form a normal observation:
* use different type of camera( imaging source dmk 21af04.as)
* use a different piece of software
* stop the tracking
IC capture
* open IC capture
* click camear being used
* device properties click off auto gain and exposure
* check if histogram isnt saturated
* adjust exposure so it is not saturated
* saving sequnece of image
* capture -> squence settings
* file name and target, pick a directory(desktop/data/YYYYMMDD) -> index at 1
* file type BMP
* Automated sequence -> interval at 1 sec -> end sequence after 400 Frames
* capture -> sequence timer -> start timer
how to turn off tracking
* set up -> enter
* targets -> enter
* trestral or astonamical ->enter
we are going to be using 2016-11-02 data

time: 17:22 arrived in dome. ENK JT AS AC AA
remove rain cover from telescope
open doors of dome (ropes(tie up), bolts)
go onto roof and observe sky
select Capella(HIP 24608) on Stellarium
RA/Dec 5h17m57.85s / 46deg 00' 40.4''
h(capella) = LST(egham) - \alpha = 1h41m52.8s(egham) - 5h17m57.85s(capella) =-3h36m5.05s
rotate dome to correct direction
callibrate telescope - move telescope manually to point at Capella, it can then know its position on the night sky and be moved using the stellarium programme
first take caps off telescope, turn telescope on(make sure everything is plugged in and switched on,checking all leads and sockets)
telescope automatically moves towards the west)
centre capella in finder scope(scope speed 5)
Synchronise coordinates on Capella ( object -> star -> named -> Capella -> Enter (2 seconds) -> Enter to sync)
move telescope away from capella
use the go-to key to get back to capella
Move to almaaz(HIP 23416) using the hipparcus catalogue method outlined in the script
Use Hip method again to move to Betelgeuse (HIP 27989), and bellatrix (HIP 25336)
open MaxIm DL Pro 5
exposure 1 sec start poor out of focus picture
change exposure to 0.1 sec, X bin 4 continuously taking images
use knobs on scope to unlock mirror and change the focal length, simultaneously slowly moving scope to get the star in the centre of the field of view of the CCD
get star in and out of focus and take picture
calibrate telescope to set on aldebaran
use focus (4 on pad) to get good focus with microfocuser that changes the camera not the mirror
take images in different exposuresmove to fainter section of sky, star cluster near aldebaran cluster 2 shows fringe from coolingtake 10 images to find saturation around 65000 for this CCD
move to 02 Tau and found bleeding and saturation at 10s, took multiple images at different exp times (1x1 binning)
found that simple auto dark callibration was on contiunued with this then took one without this

Weather - cloudy fairly poor visibility
* set up telescope, open dome, take off caps etc
* take picture of blank space, set up guide camera also
* twilight point scope at blank space look at cooling and non cooling effects
* target is betelgeuse, use to focus and synchronise camera
* move scope to pleiades, new target in order to take pictures of cluster, image with multiple stars
* centre on atlas and pleione
* look at error in plate scale as a function of flux ALL FRAMES!!!!!!!!!!!!!!!
* f[0].header this shows all the info about the image and the telescope
* shape(d) Out[40]: (1020, 1530) dx1 = d[0:500,:].sum(0) dx2 = d[501:,:].sum(0) plot(dx1) this will set a range on the x/y axis

time 10:30am arrived in dome. A Cozens, L Lenz D Bedingham S Boogert
poor weather conitions so no solar data could be recorded
used SLR camera to take images of boiler house in order to understand how the manual settings of the camera affect images
took 30 images with different exposure times and varying the ISO number, as ISO increases smaller exposure times are required so not to saturate the image.
The images are located
C:\users\astrodome\desktop\3_data\20171018_Solar
with two files showing the dark frame images taken to show the noise of the camera with the cap on the lens and light brick images taken at different exposure times with different ISO

10:30 dome. Bedingham, Cozens, Lenz
* good weather => took a few images with Canon SLR camera
* The following settings received best results: ISO=100, exposure time=1/4s to 1/8s, max. f-number
* Used rawkit Python package to transform .cr2 files into .tiff
* Applied Hough transformation to find circles in image
* Measured brick width L with ruler and received distance D from dome to boiler house brick via Google Maps
=> L = 22cm, D=104m
* From this calculated angle to be θ = 2*arctan((L/2)/D) = 0.117° = 0.22x(angular separation of sun(0.5°))
* Next steps: - take image of smooth white background to measure the vignetting effect of camera
- adjust parameters of Hough transformation to find correct circle

use DSLR to take white images to look at the natural vignetting effects of the camera, took many exposure times so to get an unsaturated image. Need to process these to get a pixel vs intensity curve to show that the fractional ratio of intensity does not depend on exposure. Also look at different colour channels and create a plot to show all 3
Then set up the telescope so as to record data, fit with sun filters and imaging source camera. Using ICcapture software.
Use shadow of the telescope to align, and adjust further with finder scope.
set telescope to the west of the sun to see it passing through the window, takes around 1min to fully pass no data recorded
Use DSLR to take images of the sun, lowering the exposure times to find an unsaturated image. Use circle finder code to analyse the intensity array across a diameter of the sun.
Attached Text files show the image numbers on the DSLR for varying exposure times ISO=100 for targets of the sun then a white light source evenly lit for investigating the vignetting effect.

10:30 at dome, D. Bedingham, L. Lenz
* cloudy weather => took no images of Sun
* Vignetting images from last week were not symmetric
=> will have to retake those images with diffuse light (outside) and a variety of exposure times to achieve different max/min intensity values,
the ratio of I_max/I_min should be approx the same throughout
Next steps:
* Take correct vignetting images with different exposure times and diffuse light
* Analyse new vignetting images and apply curve fitting to it => V(x) => can receive real intensity with I(x)*V_max/V(x)
* Estimate unscattered intensity f of Sun images
* Fit curve to unscattered intensity => Gaußian fit => should get data back (~Gaußian curve)
* Optimise f

looking into error in blue filter images taken previously
is an error in the programme with the readout, reboots and restarts did not solve this. Updated the verison of IC Capture from 2015 model to 2017, this had some minimal effect
Look at changing the Frames Per Second to a smaller amount (from 30 to 3.75) this did correct for the oscillation problem looking at blue sky
Move to try and take images of sun again with filter
Wait for sun to be away from tree.

Weather Conditions: Clear
Time: 22:40 - 1:50
Targets: Betelgeuse & Pleiades Cluster in RBG filters
Cameras Used: SBIG ST 8XME(camera 1) and SBIG ST-8300M(camera 2)
Both cooled to -20deg
Telescope already synchronised, moved and focused on Betelgeuse. Target too bright for filters. Kept saturating.
Moved to a new target, the star, Bellatrix. Again too bright for filters.
Moved to another new target, HIP26594. 15 images taken for all three filters RBG, exposure time 1.5s.
Then moved to the Pleiades, in narrow view camera (camera 1). We took ten images in each filter with exposure time 10s. And we took ten images in each of the green and blue filters with exposure time 40s.
We switched to camera 2, a wide view that could take an image of the whole cluster. The image is inverted in camera 2. We took 20 images with exposure time 0.4s with no filter.

* set to speed 5, center
* start exposure, bin 4, continuous, center object, speed 3
* adjust focus, unlock primary mirror clockwise 2 revolutions, bracketing process(see how the object is changing), object keeps moving, brightness changes, focus as much as possible, center it again speed 3, synchronize-object,star,named, click for 2 sec
* observede diffraction pattern- something is wrong with the camera, filter plate not moving, adjusting, fixed filter changing
* change exposure time to 0.3s, get star off center, focus on other, dimmer stars, adjust focus once more to see clearly
* discovered diffraction pattern in filter image
* took apart camera with help of Prof Boogert
* once camera filter in working condition, resumed observation
* took exposures of far field stars near Betelgeuse in order to focus the telescope
* shifted focus to plaidees - Atlas and Cleo
* used Astrometry in order to determine our location in the night sky
* once Atlas and Cleo found, took 0.1 interval exposures from 1 to 5 seconds until stars were saturating pixel value
* once pixel values saturated, shifted view to m41 orions nebula
* took one 7 second exposure

15/2/18 Began: 17:30
Started up telescope & opened observatory. Connected to camera with maximdl (disabled camera 2), turned on cooler to -15.
Found Capella @ LST=3:45, h= 22:27, rotated telescope mount. Changed declination to 46 degrees. Located star in viewfinder.
Began continuous 0.1s 4x4 binning image capture of CCD view. Moved telescope (speed 1) opposite to image view due to CCD being upside down, to centre Capella.
Go-to button used, caused telescope to move way off target. Recallibrating as a result. Now LST=4:15, so h = 22:57, relocated Capella. Centered etc.
With LST 4:27, Atlas found at h=0:32. dec 24 deg 6 min.
Used astrometry.net to work out stars from unknown image 1, located area in stellarium
Moved to bright stars (i.e atlas and pleione), checked again with astrometry and stellarium. Synced to Pleione HIP 17851 SAO 76229 on both telescope and stellarium (connected to telescope)
Centred on Pleione. Tested stellarium movement to other stars.
Centred on Atlas, took multiple images at several exposure times, saturating the image individually for both bright stars.
zeroed telescope, closed up dome.
Finished 20:00

Logbook for PH3010 Solar limb darkening mini-project, initial setup meeting
Present: DB, MA, JC, HS
Order of tasks for observation of the sun:
1) DO NOT STARE DIRECTLY AT SUN. DO NOT POINT UNPROTECTED TELESCOPE AT SUN
2) Go outside dome and check that sun will not be obscured by the tree, wind thingy. If it will be, will have to wait before able to take images of sun
3) Check solar filters are not damaged. Fit solar filters to main scope (and if using finder scope, fit solar filter to that). Fit CCTV lens to camera, camera to filters, filters to telescope.
4) Open dome, move opening so that allows shadow of telescope to be seen on dome wall
5) Use the shadow of the top scope (the one secured by two sets of three prongs) to align the telescope with the sun. When the shadows from both sets of prongs overlap, the telescope is (roughly) aligned with the sun
6) If using finder scope, use to target edge of sun.
7) Use IC Capture program to view camera feed (really need to jam the cable into the back of the camera to get the pc to detect it). In device-properties can control gain and exposure settings
8) Use live camera feed to target edge of sun and focus (unlock and use know on back of telescope)
9) Change declination of telescope and monitor live camera feed. Need to find centre-line of sun. This is when any change in declination results in the suns edge moving out of frame (away from centre, only changing declination in one direction will move it out of frame - the other will move it more in frame)
10) On telescope control setup-targets-terrestrial or astronomical
terrestrial will keep telescope at fixed angle, astronomical follows objects through the sky
11) Choose filter to image with. Point telescope as closely as possible to centre of sun and view image histogram. Adjust and exposure until the image is not fully saturating (has a narrow yellow bar - the zero readings - visible) but has as full a range of values as practical.
12) Return telescope to point at edge of sun, in the centre. In IC capture go to the timed capture settings. Choose an appropriate target folder and image capture filenames, set the image type to bmp, turn the 'auto display capture' to off and set an appropriate capture interval and number of captures.
Note: Sun subtends an angle of about 0.5 degrees. Previous years have taken 405 seconds worth of images for this project.
13) capture images. Repeat step 11 onwards for another filter

* Dome entered 10am. Present: MA, JC, HS, supervised by Dr. DB
* Telescope cover removed, solar filters put on
* camera and colour filters were already attached to telescope. setup checked just to be sure
* Telescope setup reviewed+approved by DB
* Dome doors opened, telescope turned on
* Moon was still visible in sky - dome doors moved to allow viewing of it
* Moon used for focus (coarse and fine), took a couple of images of nice craters
* Moon found by (roughly) lining it up with the telescope, then with the finder scope, then with the camera image
* Dome doors moved to allow viewing of sun, telescope slewed to find sun
* telescope shadow aligned on wall behind telescope
* telescope moved to bring the two rows of knobs into alignment (i.e. telescope pointing at sun)
* Using camera feed, approximate equator of sun found at one edge
* Test images taken
* Moon and test sun images stored in focus_images folder
* Colour image sets taken.
* All image sets performed by pointing telescope ahead of suns motion and switching to terrestrial mode - motion of sun across sky then carries sun across the frame of view.
* All image sets taken over 3 minutes 10 seconds. This time determined by timing a test run of the method.
* 1 image per second taken for the length of the image set.
* Used maximum gain for all image sets. Exposure determined by manually slewing across the sun and trialling different exposures. Aim was to get as close to having maximum pixel values in the image, without actually having any maxed out pixels
* Where necessary, solar eclipse glasses were used to directly view sun e.g. to determine if clouds were obstructing the sun, or just the area around it
* Clear Filter 1:
* Gain 799, exposure 1/1000 seconds
* trees obstructing parts of image set - produces obvious errors in dataset
* Clear Filter 2:
* Gain 1023, exposure 1/4000 seconds
* Blue Filter 1
* Gain 1023, exposure 1/154 seconds
* Some obstruction of sun by clouds
* Blue Filter 2
* Gain 1023, exposure 1/154 seconds
* Still some clouds, but far fewer than with Blue Filter 1
* Green Filter 1
* Gain 1023, exposure 1/308 seconds
* Lots of clouds
* Green 2
* Gain 1023, exposure 1/308 seconds
* Even more clouds
* Red 1
* Gain 1023, exposure 1/1241 seconds
* A few false starts (so the file indexing is messed up), but managed to get a good run of images
* Was not able to perform another run with the green filter, due to increasing cloud cover
* Dome doors repositioned above door to roof and closed.
* Solar filter removed and lens cap replaced. Filter stored back in its home.
* Telescope returned to 0h0d
* NOTE: Minor mix-up with imgae file names. All image sets are stored in the appropriate folders / .zips for the colour filter used, but the some image sets use the wrong colour name in the individual image filenames. Recommend handling image sets carefully / renaming appropriately when used.

* Present JC, AD
* Began cooling at 16:45 to -12 deg C (~90%)
* Filter wheel set to Clear, Red, Green, Blue
* Centred on Capella and took GPS-fix. Encountered problem: telescope believed it was -1h RA from Capella however this offset was constant.
* Edit: This seemed to just be an issue with the coordinates read-out on the paddle.
* Centred on M35 and took 1000x0.1s exposures to focus.
* Then took 60s exposure- significant effects of moonlight on image- change target to M36 (RA/DEC: 05 37 13.8/34 09 04)
* Light pollution significantly reduced suggesting moon was indeed the source.
* took 60s and 90s exp in all filters
* moved to (RA/DEC: 05 37 31/34 07 50) and repeated.
* took dark and bias frames before finishing observation at 9:30pm.

PEC Training
Meade LX200GPS Pec Training
- Setup -> Telescope -> RA PEC -> Training
Method
- Connect to Stellarium and MaximDL
- Telescope pointed at Vega synced
- Moved to Epsilon Lyrae (epsilon_lyrae)
- Camera disconnected from MaximDL and connected to PHD Guiding
PHD Guiding keeps the star in the same position at all times allowing the PEC to be trained
Data read with PEC Editor (MyScopeShort) and saved as *.txt file for further analysis
PHD Settings
1st PEC
- RA_PEC_DATA1.TXT
- 0.2s
- Default Advanced Settings with:
- Full Frame
2nd PEC
- RA_PEC_DATA2.TXT
- 0.2s
- Default Advanced Settings but:
- Subframe
Processing Code:
- To be added
Plots for PEC Data:
Test images:
NGC6675 (Spiral Galaxy) - 1 (ngc6675_possible) and 5 min (ngc6675_definite) exposure, 2x2 Binning

Focus and Filters
Average filter wavelength
- Blue: 450mm
- Green: 550mm
- Red: 650mm
ST-8ME Quantum Efficiency:
- Blue: 55%
- 1.82x exposure from clear
- 60s clear -> 109s
- Green: 70%
- 1.43x exposure from clear
- 60s clear -> 86s
- Red: 75%
- 1.33x exposure from clear
- 60s clear -> 80s
Test Images
M57 - Ring Nebula
M56 - Globular Cluster
- 1x60s Luminance image
M27 - Dumbbell Nebula
- 9x60s Luminance images stacked to form a 6x60s image
- 1x109s Blue image
- 1x86s + 2x60s Green images
- 1x86s + 5x60s Red images
During the Dumbbell Nebula imaging the filters were accidentally changed due to the mouse scroll.
- Possible workarounds:
- Use autosave function to take images
- Check before taking a new single image

APIs:
* [[http://seal.web.cern.ch/seal/documents/minuit/mnusersguide.pdf][Seal Minuit]]
* [[http://iminuit.github.io/iminuit/api.html][iMinuit]]
*Performance (measured with Python %timeit() magic function):*
* PyMinuit: best of 3: 13.9 s per loop
* iMinuit: best of 3: 11 s per loop
*Conclusions:*
* iMinuit is easier to install than PyMinuit
* iMinuit is faster than PyMinuit
* iMinuit have more features than minuit (e.g. export to LaTeX and fake functions)
* Both detected and successfully minimized a 2D Gaussian on all the stars with same parameters
* PyMinuit "accidentely" fitted more Hot Pixels than iMinuit
* PyMinuit includes Simplex and Scan methods, which are not available on iMinuit
* PyMinuit is more stable - annoing bug in latest version cause segfault it limits, steps, ... are not set
Keep PyMinuit for now.

| Created: 10 Sep 2013 16:48:33 | Last Revised: 11 Sep 2013 15:49:16 | Public.PedroPaiva | Building Python on cygwin |
pre-requisite: have [[http://www.cygwin.com/][Cygwin]] installed and a GNU compiler.
Cygwin comes with python pre-installed, from there one can install new packages with:
* easy_install packageName
* pip install packageName
To use ==pip== you must install it first using ==easy_install pip==
The ==pip== method is favorable for it allows you to search, uninstall and upgrade packages easily.
==pip== guide:
* ==pip freeze== - display currently installed packages
* ==pip search packageName==
* ==pip install packageName [--upgrade]== - installs or upgrade an already installed package
* ==pip uninstall packageName== - uninstall a package
*Packages installed*
* ipython
* numpy
* scipy
* pyfits
*To be installed:*
* matplotlib
* opengl
* pyside
* pywin32 (don't support cygwin)
* pyminuit ([[http://code.google.com/p/pyminuit/wiki/HowToInstall][detailed guide]])
1 Download the required files: [[http://code.google.com/p/pyminuit/downloads/detail?name=Minuit-1_7_9-patch1.tar.gz][Minuit-1_7_9]] and [[http://pyminuit.googlecode.com/files/pyminuit-1.2.1.tgz][pyminuit-1.2.1]]
1 Extract and change to Minuit directory (under cygwin)
1 Compile Minuit with:
1 bash configure
make
make install
1 Change to pyminuit directory ( ==cd ../pyminuit-1.2.1== )
1 Build and install with: ==python setup.py install --with-minuit=/location/of/Minuit-1_7_9==

Ring Galaxy (NGC1291)
Protostar (IRAS 20324+4057) "The bizarre looking ring galaxy NGC 1291 in Eridanus.
These fairly rare types of galaxy are usually much fainter objects, but this one at "only" 33 million light years away is easily visible in modest size telescopes though the faint outer ring of material is much fainter than this.
Its strange appearance is the likely the result of a collision with another galaxy in the distant past.
20"CDK with FLI-PL6303e camera. LRGB. L: 70mins. RGB: 5/5/10mins" - Damian Peach
IRAS 20324+4057 is a Protostar in the Cygnus OB2 Association, 4,500 light-years (1,380 parsecs) away.
This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
INT: H-alpha
cyan ACS: F606W (V)

After turning telescope on, it successfully received GPS signal and did not started the usual RA movement.
The Camera was connected to Python via MaximDL
Telescope and Focuser connected to Python via the POTH Hub
Coordinates in agrement between Scope, Python and Stellarium
Target was set to be -0.1º RA from current telescope position and Python SlewToTarget was tested.
Telescope moved the right amount and stopped, both telescope and Python alerted when ready.
A second test was made with +0.5º RA. Also successfully.
Still with small (-0.1º RA/DEC and +0.5º RA) movements, Python SlewToCoordinates was tested successfully.
With the tests done, the telescope was moved to Vega via controled movements on Stellarium
Vega was inside the Camera Range, demonstrating that the Park Method works.
Vega was recentered (-0.01 on RA) and the telescope was manually synced.
During this test, movements as small as 0.003º on RA proved to have no effect whatsoever.
The next step was to test the focuser and the camera.
First, while still on continuous mode of the camera, the Python-Focuser connection was tested.
Python can read the position and move the focuser. Units are steps. 1 step = 20µm
Having confirmed that one can move the focuser with Python, Vega was taken out of focus to test if we could focus the star using a small

prin = True

POTHFocuser.Move(step)
while POTHFocuser.IsMoving:
if not prin:

*Focus movements*
* Positive -> In
* Negative -> Out
*Tests*
The data below have a significant experimental error associated with the not fixed measuring equipment.
Also, they can have errors related to a possible angle between the measuring equipment and the in-out axis therefore, the real value would differ by a factor of cos(theta)
*out*
* move(-5000) - 1.86mm
* move(-5000) - 1.80mm
* move(-5000) - 1.86mm
* move(-5000) - 1.81mm
* move(-5000) - 1.88mm
* *mean = (1.842 ± 0.031)mm*
* move(-1000) - 0.31mm
* move(-1000) - 0.40mm
* move(-1000) - 0.44mm
* move(-1000) - 0.27mm
* move(-1000) - 0.45mm
* *mean = (0.378 ± 0.076)mm*
The out movement is coherent and 5000 steps is indeed equivalent to 5x1000 steps
This give 1 step aprox 0.37µm
*in*
* move(5000) - 1.52mm
* move(5000) - 1.55mm
* move(5000) - 1.52mm
* move(5000) - 1.48mm
* move(5000) - 1.57mm
* *mean = (1.528 ± 0.031)mm*
* move(1000) - 0.21mm
* move(1000) - 0.20mm
* move(1000) - 0.15mm
* move(1000) - 0.30mm
* move(1000) - 0.18mm
* *mean = (0.208 ± 0.050)mm*
The in movement is 25 to 50% smaller than the out movement (depending on the movement size) with larger movements closer to the equivalent out.
This give 1 step being between 0.2 and 0.3µm
*Conclusions*
The execution of the above movements led to the following conclusions:
* Focuser always finishes in a 'in-movement' (e.g. asking to move out will make the focuser goes more than needed and come back about 1mm)
* This causes the isMoving check to return before the focus being ready.
* Focuser limit less than aprox 30k steps when going in.
* When close to the limit, focuser will overstep (move(5000) caused the focuser to move 2.76mm)
* Focuser isn't ready when isMoving returns False.
* There's a time gap when a second comand will be accepted but not executed.

[[http://www.newastro.com/book_new/ebook/c2d.pdf][Diffraction aids]]
---------+++ Using a Bahtinov mask to find the focus:
Based on Laurie's idea and [[http://starryvistas.net/articles/focusmask/focusmask.aspx][this article]] a set of 144 images were taken.
3 images for each of the 48 moves made by the focuser. All the movements were 'in' moves of 250 steps.
The images had a 5s exposure time and a master dark (made of 10 dark) was made and reduced from the images.
On each image, a gaussian was fitted to the brightest star (142/144 success) and the amplitude and sigma median were taken for each set of 3 images per focuser position.
The data was then plotted and assumed to be in a quadratic form. The results can be seen on the images below.
For the Sigma X values, the minimum can be found at: 4841 steps
While Sigma Y minimum is at: 5411 steps
And the Amplitude maximum at: 6804 steps
According to [[LogBookAstronomyEntry0015]], the 2000 step (aprox 600µm) difference would be more than double the depth of field for the telescope [[http://starizona.com/acb/ccd/advtheoryfoc.aspx][(287µm on a f/10)]].
A visual analysis of the graphs would suggest a minimum and a maximum for Sigma Y and the Amplitude close to 6000 steps and, visually, the image at step 5750 (image set 23) is the sharpest presenting a nice 'X' diffraction pattern produced by the Bahtinov mask.

* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* Attempted Installation of Python Canopy on personal laptop to begin data analysis but fails to install on Windows 8.0 (Attempting update to 8.1 to see if it rectifies issue) [Installed 32 bit version instead]
* Set temperature value to -07.5 deg C, left for 30 - 40 mins to stabalise.
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* For data analysis will need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.

Using Autosave feature to speed up process, Hence file format has changed to: T-10.0-001-E0001
Must go back to data taken on the 18/10/2013 and rename files for consistancy -> Done.
Proceeded to take another 120 dark frames at -7.5 degrees, as with coolers on 100% sensor temp would not go below -10.6 degrees.
Proceeded to take anothe 120 dark frames at -2.5 degrees.
CCD will then be reset to 0 degrees, and frames will be taken every 30 seconds as it is cooled from 0 to -10 degrees. The exposure time will be 2 seconds. Due to lack of time this will be postponed until next week.

---------+ Project meeting on 24 / 10 /2013
Present: Chris Haynes, Paul Hallam, Ryan Cheale, Dr Boogert, Professor Cowan.
Continued discussion on taking and analysis of dark frames.
Due to the dome not being cold enough during the day, it is difficult to cool the camera down to -15 or -20 celcius. Therefore, the remaining readings will be taken further into winter, when the dome is colder.
Objectives for analysis of dark frames:
* Plot a histogram of the -5°C, 60 second frame and compute the mean, median and standard deviation.
* Plot the column mean and consider the standard deviation for all columns.
* Plot the standard deviation as the square root of the mean and check to see if it's a Poisson Distribution.
Additionally, we should think about the dark current rate (the rate at which an electric current is generated in the chip due to the production of electrons and holes) and how to compensate for it.
We should also consider what the faintest star we could detect would be, looking at the point spread function of our telescope.

---------+++ Activity Log
* Took off cover for telescope & Camera
* Turned on Camera and followed steps detailed [[Students.UnderGraduates.RyanChealeCameraTechnicalAspects][here]]
* Set temperature to -10 deg C, waited 30 - 40 mins for stable temperature
* Used Autosave Sequence located at 'Desktop/Data/20131016_RC/25darks60s.seq'
* Autosave feature allows running of each permutation whilst saving automatically
* Format T-tt.t - NNN - Eeeee.fit where T - temperature, t - temperature value, N - repetition (==20) , E - Exposure, e- Exposure time value (0.1s, 1s, 5s, 10s, 60s, 180s)
* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* turned off the coolers on the camera to allow it to reutn to room temperature.
* Proceeded to take data in 30s intervals for 30mins whilst turning the coolers back on and allowing the temperature to reduce to -10 deg C to see what effects allowing the temperature to stabalise has
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* For data analysis still need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.
Python
* Began the use of the canopy environment to begin data analysis in Python.
* Running into multiple problems with the canopy environment with plotting graphs
* Have made plots for the mean, standard deviation, max and min values of the data set T-05.0-NNN-E0600
* Struggling to create histogram plots, either the kernal or the environment tends to crash when trying to create a histogram of a single fit file
* Next steps:
* Produce median plots
* Refine code so only needs slight input alteration for other data sets
* Produce histograms and then further plots based off of the histograms
* begin analysis on cool down data.

A study into the variation of background pixel count with temperature.
Initial CCD temperature was recorded to be 18 degrees. Coolers were turned on and CCD cooled to 0 degrees over the course of an hour, to ensure the entirety of the CCD began at zero degrees for the following study.
Coolers were then set to cool the CCD to -10 degrees, and one second exposures were to be taken every 30 seconds for one hour over this cool down period.
The data shall be saved in the following format: Cooler_Study-001E001
Also this shall also provide 29s exposures between the 1s exposures, which shall appear like this: Cooler_Study-001E029. This data will not be analysed.
When this collection of data has been finished, CCD was at a constant -10 degrees. The CCD coolers were switched off, and the CCD warmed back up to room temperature. Using the same method, one second exposures was taken every 30 seconds for one hour over this period.
The data shall be saved in the following format: Cooler_Study_2-001E001
Again this will also produce data that will not be analysed, in the form of: Cooler_Study_2-001E029
Room temperature in this case is 25.6 degrees.

---------+++ Telescope Set Up
* Target Delta Cephei selected using Stellarium and AAVSO catalogs
* Open shutters (ropes, pull apart, tie off ropes, motor control
* Turn power on
* Press power switch on telescope
* Removelens caps
* Point towards Vega
* Line up with finer scope
* Take continuous frames 0.1s
* Center Vega in frame
* Synchronise Vega with Maxim DL and Stellarium
---------+++ Target Information
* Pulsating Variable star, magnitude variation 3.5 - 4.4, Δm = 0.9
* Period 5.4 days
* Next maximum, 07/12/2013, 9:32
* RA: 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From simulated light curve - expected Δm(max) = 0.26, expected Δm(min) = 0.01
* From light curve of Delta Cephei, and time of next maximum, we believe the magnitude should be decreasing
* Companion star HIP 110988 used as a reference star
---------+++ Initial Observation of Delta Cephei
* Centered on Delta Cephei - did not use Stellarium as could move telescope through the pole
* Frames were taken using different filters, initial exposure times:
* No filters - 1s
* Blue filter - 10s
* Green filter - 3s
* Red filter - 3s
* Took sample frames using this-set up, max pixel count was found using Python
* Re-evaluate exposure time to ensure max pixel count was in the range 55000 - 60000
* Re-evaluated exposure times:
* Focus filter - 1.1s
* No filter - 1s
* Blue filter - 10s
* Green filter - 5.1s
* Red filter - 3.3s
* Decided to take 5 repeats for each of these, and 10 repeats for Dark and Bias frames
* Autosave feature was used to take a sample set of data
* Residual image of Star found on Dark frames - low pixel count
* Implemented a 'Trash' frame before the Dark frame to attempt to remove this -> some residual image still remained
---------+++ Observation of Delta Cephei
* Autosave feature took approximately 10 - 15 minutes to run
* Approximately three runs were taken per hour
* Delta Cephei was observed for 5 - 6 hours
---------+++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope
* Turn off camera
* Turn off telescope
* Put cover back on camera
* Close dome shutters
* Turn off PC monitors
* Turn off lights and leave dome

20140213 LN
Reasonably clear and forecast to be good. Worth a try to get some practice in.
* CCD at -15oC
* Aligned to capella - very high in sky.
* Went down from 46 to 37 DE to theta_aur as capella saturates the camera.
* Take subframes to practice focussing. Recorded 400 frames of theat_aur for analysis later. SNR is good as super bright. Peak around 30000 ADU. Jumps around A LOT so will have to align by centroid. Then can have a look at PSF.
* Exposure 0.1s
* 300 exposures recorded in 10m12s
* 400 exposures recorded in 13m37s *Sat bhatinov mask carefully on front of scope. Recorded 50 images with same setup as before. Not so clear.
* Exposure 0.5s
* Not so clear. Pattern seems very small indeed on CCD compared to internet images. Collimation is definitely poor and its windy so don't expect it to be great. Anyway, reasonably good in focus.
* Having a look at the Pleiades. Too extended to see anything nice and certainly with the seeing. The stars are very bright and the nebulosity not so, so quite hard to observe under these conditions.
* Imaged Andromeda ok. 30s exposures.

Using the spectrometer to find the brightest spectral line in mercury and Find the best micrometer reading for the angle of the camera.
Camera was ST-7E, Setup SBIG Universal.
Temperature for all the images was -6.5 deg C.
*Focus*
Exposure time: 0.1s; Grating distance 1.814mm; Camera angle micrometer reading 2.495 (heavily sloped)
Used continuous range to find a reasonable staring point.
Used range of 18mm to 20.5 mm in steps of 0.5
Reduced range to 19mm to 20.5mm in steps of 0.10
Reduced range further to 19.50mm to 19.80mm in steps of 0.05
*Camera Angle*
Exposure time: 0.1s; Grating distance 1.814mm; Focus distance was 19.60mm for this
Used continuous range to find staring point.
Used range of 2.50mm to 5.50mm in increments of 0.5mm to start.
Reduced range to 4.00mm to 5.00mm in steps of 0.10mm
Reduced range further to 4.45mm to 4.65mm in steps of 0.05mm
Found the best angle to be _4.60mm_
*Brightest Peak Data*
Looking through the spectrum the brightest peak, found at 4.00mm in grating micrometer.
This was saturated so the lamp was moved back by 5cm which was still saturated, then we moved it back by another 5cm which put the lamp back from the optical fibre by 25cm. This reduced saturation where refocus was done. Seemed to saturate at 50,000 confirming it was brightest peak.
Used this to check the focus and recalculate.
used a range from 19.50mm to 20.50mm in steps of 0.10mm
Found best focus distance on micrometer to be _20.10mm_

27th Oct 2014 Msc Observation.
*Begun:* 18:30
*Finished:* 22:30
Conditions: Mostly clear, a little muggy. No cloud coverage.
Begun observation session with a run down of the procedure to prepare the dome.
*Dome Procedure:*
-
Enter dome
- Close the hatch to prevent heat rising and entering the dome. The floors beneath are heated which causes a ‘chimney’ like effect if the hatch is left open as the hot air from below will rise up through it. Ideally the scope and dome should remain cool so noise due to thermal fluctuations is kept to a minimum.
- In the Maxim DL suiteconnect to the telescope. This allows control of the camera for example you can set exposure times and capture images from the program.
- Enable the CCD cooler in Maxim. This should be done ~1 hour before taking exposures. If you take observations too soon after enabling the cooler you get a ring like effect on your observations around the outer area of the frame. The ring progresses further to the sides of the frame as the CCD cools until it eventually disappears.The set-point of the cooler is set to -10 degrees celcius and the CCD itself fluctuated around this point slightly once the cooler had taken full effect.
- Untie the ropes that control the shutter of the dome. Pull on ropes to open the shutter of dome, if the shutters do not open with ease, there is a long stick with a metal prod at one end which can be used to manually push the shutters open from near the top of the dome.
- Once shutter is open, tie the ropes off again to make sure that they are kept out the way of the moving parts of the done which can rotate bothe counter and clock-wise
- Using the door on side of dome, go outside and do some preliminary naked eye observations to find an interesting object to observe (this is important for aligning the telescope as detailed later on). This allows you to plan roughly where the telescope and open shutter should be pointing to allow unrestricted viewing.
- Using the dome control unit, align the dome opening with what you want to observe.
- When finished observing, realign both the dome and telescope to their origional position. Close the dome shutters and tie up the ropes.
To begin making observations you need to align the telescope to a bright object in the sky and then enable tracking. Tracking corrects the position of the telescope relative to the sedereal motion of the stars. This is necessary because the field of view of the telescope is so narrow if it was left stationary, the object you are observing will move out of frame. To align the telescope, the first step is to identify a bright object visible to the naked eye in the nights sky. You can acess the roof from the dome via. the door on the side. Once on the roof you are able to evaluate potential targets. We identified the star Vega (25ly away, 2.1M0, alpha lyrae - the brightest star in the lyra constellation and 5th brighest in the night's sky). The star charts provided in the program stellarium coupled with manual positional measurements allow you to identify the star you are looking at with the naked eye.
Once a object in the sky has been chosen, the next step is to align the telescope to enable the activation of tracking.
- *Telescope Alignment:*
-
Use a high speed on the control paddle (speed button -> 9 is fastest, 1 is slowest on number pad) to crudely align the scope with what you want to observe using the arrow buttons. This can be done roughly by eye by lining up the two bolts on the side of the telescope with what you are looking for.
- Then use the viewfinder which has a set of crosshairs to align the scope more accurately with the object in the sky. A medium speed setting on the paddle can be used to move the scope with a greater deal of precision.
- Once the crosshairs are centred on the object you wish to view, take an exposure in the maxim DL suite. Once the image has been taken and downloaded you can adjust the scope to get the object centred in the frame. If you set maxim DL to take continuous ~1s exposures you can get a better sense of the best way to align scope and object.
- Once the scope is aligned, enable GPS lock. This continuously corrects the scope to account for the rotation of the earth. The field of view of the scope is very narrow causing the object you are observing to move through the frame if the scope remains stationary.
- Once tracking is enabled, the scope should keep the object you are trying to view in frame automatically.
- Using the control paddle, tell the telescope which star/object it is currently aligned to
- With the telescope connected to stellarium which now allows you to control the scope through the program itself. Using the star charts, you can align the scope to stars/objects shown in stelarrium. (Wait for the ‘beep’ if you move the scope in the program. The scope moves quickly at first but then makes finer corrections to ensure the scope is aligned well. The 'beep' occurs once the telescope is properly aligned, it can take some time ~20-30 secs).
- While repositioning the telescope it is important to be aware of it's orientation with respect to it's base. The telescope is capable of flipping over on itself which can cause the CCD attatchment to collide with the stand. In a situation where this may happen, power down the telescope via the power controls located on its stand immediately.
With the telescope aligned you can control where it is looking via. the stellarium program. Multiple exposures of Vega were taken at different exposure lengths using the Maxim DL program.
Using stellarium, the telescope was then trained on the open cluster M-39 in the constellation cyganus (800ly away from earth). Again took multiple exposures. The cluster is composed of a number of stars. Using the star chart in stellarrium the star patterns were compared to that shown in the exposure allowing for individual identification of the stars the cluster is made up of.
You have the ability to manually focus the telescope. If it is out of focus the exposures of stars can present as donuts (dark centres with bright outer ring) or they seem flat and blurred at it's edges. The procedue to manually focus the telescope is first to 'unlock' the mechanism. There are two dials, the shorter one can be rotated to unlock the device allowing the second longer dial to be turned focusing the telescope.
Last target of the night was the andromeda galaxy known as M-31 (as it is a messier object) and is 2.5x106 ly away from earth and the closest spiral galaxy to the milky way group. This galaxy has a mass ~ 1.5x10^12 M0. 10 exposures were taken one after the other with the intention of eventually using them to form 1 image with considerably less noise.
An interesting point to note is that movement of the atmosphere above the telescope can cause exposures to shift in and out of focus. This was made evident as during continuous exposures of M-39, the stars were alternating between being in focus and out of focus.
The exposures taken during the night of observation are attached to this post.

*Observations of the Spectrum of Betelgeuse*
Started looking at Capella. Using a small sheet of tracing paper to allign the star in the optic fibre coupling. With Capella at a high Altitude we switched to Betelgeuse as a target to make allignment easier.
Viewed Capella at
5hrs 20' 30'' RA
45deg 8' 2'' DEC
with the micrometer at Grating-4mm, Angle-3.25mm, Focus 20.2mm.
changed the RA 5'' either side to align it centrally while observing the intensity recieved.
*Betelgeuse*
Next look at Betelgeuse,
5hrs 58' 32' RA
6deg 25' 30'' DEC
Took a 30s exposure at 4mm to look at the spectrum as best as possible. Then took 60s exposures of Betelgeuse between 0mm and 10mm in steps of 0.5mm.
After Betelgeuse we briefly moved to the Orion nebula however it was too dim to observe.
*Pollux*
7hrs 46' 14'' RA
27deg 59' 18'' DEC
Again took 60s exposures from 0mm on the grating position micrometer too 10mm in steps of 0.5mm.
Laurie left at 23:00
*Castor*
7hrs 35' 22'' RA

Please edit and put your text etc. here
Start Time: 19:00
Conditions: Slightly cloudy at start, quickly became clear around 8pm and remained clear.
Observations:
*Castor (Alpha Gem)*
Aligned to Castor, RA: 7h 34m 35.87s, Dec: 31dg 53' 17.82" Apparent Mag: 1.93
Ring visible due to cooling of CCD chip taking place.
*Near Castor*
Observed multiple stars near Castor with low magnitude (10 - 15)
No images taken.
Ring still visible.
*NGC2388*
Centred on galaxy NGC2388, Apparent Mag: 14.
NGC2388 was chosen as a target as it is known to currently contain a Supernaova of Apparent Magnitude 15. See http://www.rochesterastronomy.org/snimages/snactive.html
Supernovae: PSN J07285387+3349106, RA: 07:28:53.87, Dec: +33:49:10.6, z = 0.013790
One frame was taken at 120s exposure. Stars were cross checked with Stellarium and were found to be low magnitude (10-16). Two other galaxies were also clearly visible, NGC2385 and NGC2389. The cooling ring was still visible at the edges of the frame. This location was chosen for the target of this observation due to the number of low magnitude stars, and the presence of three galaxies.
Uploaded a frame to astrometry.net
Experimented with 180s exposure, decided to use 120s.
Stacked frames using MaximDL built in image stacker to invstigate noise reduction.
Images taken:
Data was taken in bursts of 9 images, 3 Light Frames with 120s exposure, 3 Dark Frames at 120s exposure and 3 Bias frames.
Dome was realigned every 2 bursts to ensure unobstructed view of the sky.

---------+ 2015 05 20 LN DSLR Observation
* Trying out DSLR on back of scope
* Benefit - easy live video to investigate focussing, wide field of view
---------++ 20:30 start
* Dismounted SBIG camera (in case)
* Canon DSLR bayonet adapter + BADER 2" - T/2 Nosepiece on back of micro-focuser
* Observed Moon, Venus & Jupiter during twilight ~ 21:40
* Aligned & synchronised to artturus star to the south as visible to the naked eye
* image of M3 globular cluster ~ magnitude 6 - can make out ok in photos but still blue sky background as still slightly light
* 2155
* Trial of Deep sky object - still lightish but will keep iterating over objects
* Bodes Nebula mag 6.9
* Of note is that the DSLR is slim enough for a polar flip of the mount. Haven't, but can.
* Whirlpool Galaxy
* Getting better images but can only really see core of galaxy - still to much sky glow
From images of a single bright star or say of Jupiter and it's moons, you can see what appears to be both coma and chromatic aberration. The edges of non-point like objects have an orange tinge on one side and a blueish tinge on the other. Jupiter is relatively low just now so there is a strong affect from the atmosphere / imaging but still Jupiter had an asymmetric tinge. The moons were also quite distorted. Although the 'live view' gives you some indication, it simulates the exposure settings and can distort the image a little. Best to take images directly and zoom in to compare. Not too different from live view though.
* Telescope likely needs collimation, but the trouble is finding a good enough night for to be able to observe any improvement.
Sky much darker now. While no clouds around, there is a bit of haze - can't see huge multitude of stars.
* Starting at 3845 images of great cluster in hercules.
Finish at 22:20

---------++ *Before taking data*
* Time of turn on: 18.20.
* Cooler set to -7 degrees.
* Temp at -6.9 degrees at 18.30.
* Center the telescope on Vega.
* Aling the telescope to Vega. (~Mode on the controller)
* Speed 5 and later 3 on controller while focusing on Vega.
* Microfocuser used to fine focus.
* Speed 3 to place Vega in the center of the image.
---------+++ Alpha Persei Cluster (Cr 39, Mel 20)
* We chose our cluster as the Alpha Persei cluster.
* To focus on the cluster we chose a nearby bright star Mirphak.
* We used it to correct our ofocusing and we synched Stellarium wityh the telescope.
* We choice a patch of the cluster (HIP16001) and took 10 vimages of 10 second exposures. ( x binning set to 1, x anmd y originally inverted, this was reversed)
* 5 bias frames and dark frames of 5 1min exposure.
* Took 3 40 s red.
* Took 3 40-s gtreen.
* Took 3 90 s blue.
*
* Move to a different patch (around RA:3h29min29s, DEC:49deg44'16")
* Ian joined us at 20:00
* 3 images of 60s visual.
* 3 images of 120s red.
* 3 images of 120s green.
* Finished taking data at 8.30 pm.
---------+++ Dark and bias frames
* Started taking dark frames. 5 images of 120s.
* Take 10 bias aswell.
Observation finished at 8.56pm.

The aim of the session was to modify the parameters of the camera. Using only OpenCv it was impossible to set the camera's parameters with known units.
py-ic-imaging-control was downloaded from: https://github.com/morefigs/py-ic-imaging-control
py-ic-imaging-control is a python wrapper for the IC imaging control software development kit from the imaging source (TIS). It provides control to TIS cameras, and can serve as an alternative to using OpenCv to access the cameras parameters.

The DMK camera was fixed to a tripod and pointed at the moon.
Run1: Gain set to 180 and images were recorded of the moon at a frame rate of 7.5 frames per second. The algorithm left the exposure setting on 1 as the image was not over or under exposed on this setting.
Run2: Gain was increased to 1023. The images were over exposed and the algorithm accounted for this by changing the exposure setting in increments of 1. It was noted that this was very slow to respond to large and sudden changes in conditions.
Run3: The code was modified such that the amount the algorithm changed the exposure setting depended on the number of pixels that were saturated. This massively decreased the time the algorithm took to find the correct exposure setting. See screen shot.
Images were also taken of Orion's Nebula, see image file names for parameter settings.

Az/Alt: 318deg 44'20''/38deg34'50''
Took testing pictures: Cooling_1 and cooling_2, can be seen a ring surrounded by the ice. Secong image shows larger ring, meaning hte camera is cooling down
Cooling_3 image is clear and even
Checked the wether with met office, clouds are exopected to clear for the rest of the night
Finding the star by eye, alighning the tescope, using stllarium found it was Procyon
As it wasn't clear that the star is Procyon, checked with Rigel
Took images of the delta cep with no filter and with filters: red, green, blue and spectroscope. Aimed for 50 000 pixel value - the closest to the maximum possible p.v.
Exposure time was increased as different filters were applied, because different filters obsurb more light.
Cloudy weather led to taking many pictures for blue filter with longer exp time, 16 sec.

Please edit and put your text etc. here
---------+ Finding focus of optical fibre
* The focus of the optical fibre was found by taking a relative distance between the lens and the position of the optical fibre, and measuring the amplitude of a spectral line from the laser found at 3.5mm.
* taken at 1mm intervals between 230m and 270mm.
* Fit with hyperbolae as approximation
* distance measured with ruler so very approximate i.e ±1mm
* Best focus was found at 250mm±2mm
* Iris was almost closed as the laser would saturate camera at shortest exposure.
* also took more data as SBIG ST-7E was cooling.
* Just need extra part to connect firewire camera, so that the alignment can be competed.

Please edit and put your text etc. here
---------+ Focussing Beam Splitter
* To find best focus should be able to focus onto a single fibre, once one illuminated, in focus. will have to use extension rings for optical fibre.
* CCD camera can then be adjusted until in focus.
* Focus by shifting backwards and forwards on rails.
* Find focus of camera with max intensity and minimum width of laser.
* Use diffuser or neutral density filter, will need neutral density filter.
* Make two plots of intensity on camera and fiber and adjust until peaks overlap.
* Such that there are two plots which look similar to:
---------+ Aligning Beam Splitter
* Align by moving the mirror horizontally and vertically until maximum intensity
* possibly get 3 more irises, to control aperture at camera, fibre and entry, to make sure always have good alignment.
* As now in focus, can scan around fibres and find the relative positions compared to the end where they are arranged into line.
* This could help with finding best position of ray on camera
* Look up mirror and see how much change in angle before lost fibre, one full turn until laser out of view.
* try to get two irises as far away from each other for best alignment.
* once part for CCD arrives, move around and find relative positions on camera to positions on optical fibre.
---------+ Relating to telescope
* Have to use larger beam size so that f# is the same as the telescope, f# = 10,
* currently 3 dioptre lens, so 1/3 m focal length, this means need a beam diameter of 33.3 mm or a longer focal length.
* as , where f is the focal length, d is the diameter of beam or aperture and f# is the f number.
* consider which camera to be used.
* beam splitter reflects 30% and transmits 70% so check this.
---------+ testing intensity
* tested the intensity at reflection and transmission, with diffuser and tissue in front of laser, tissue made intensity vary substantially so averaged over five frames, the reflection intensity was found to be 3% of the transmission intensity, however there could be problems with focus and alignment at the refection, need better analysis of this.

---------+ Aligning Camera and optical fiber
* Spectrum images,
* Exposure: 0.1s
* Temp: 10 deg
* used subframes around spectral to speed up
* FireWire camera * Exposure: 1/500 s
* The FireWire camera was attached to the beam splitter and connected to IC capture
* Optical fiber was attached using a spacer to approximate the same focal length as the FireWire CCD
* Initially an approximate focus was found on the FireWire camera.
* Then the angle of the mirror was adjusted vertically such that the laser beam was scanned vertically.
* images of the position on the CCD and the spectrum were taken at a range of positions.
* The amplitude of the spectral line was then recorded with position on the CCD.
* This gave a plot shown below for the maximum intensity. i.e centre of fiber
*
* This was then repeated for a scan horizontally, which gave the plot below.
* The best positions were found to be at [190,218] pixels, i.e 190 pixels across and 218 pixels down
* The the focus of the image was to be found.
* The box which the beam splitter and camera is attached to was placed on the rails and scanned backwards and forwards using a ruler for approximate focal length.
* Images were recorded for both the camera and optical fiber, and the amplitudes were plotted against focal length.

Please edit and put your text etc. here
---------+ Alignment of Camera and Optical Fiber
* SBIG camera,
* Temp: 10deg
* Exposure: 0.1s
* subframe around fibers
* FireWire Camera,
* Exposure: 1/500 s
* Took focus measurements first by moving beam splitter to find best focus.
* Best focus was found by subtraction background of spectral line image and summing pixels
* Best focus for image was found by finding max pixel value
*
* The optical fiber focussed ~6mm from the FireWire camera
* Optical fiber was adjusted such that it is as far out as possible using the smallest spacer, and the camera was adjusted so that it was as close to the beam splitter as possible.
* This was to close the 6mm gap found earlier
* The fiber and camera were then realigned as the FireWire camera will have been rotated slightly and moved out of alignment.
* Both horizontal and vertical alignment were used and the best positions were found at maximum intensity the same as for the focus.
*
---------+ Attachment of guidescope
* Two mounts for the dovetail plates attached on the top of telescope, plate then attached.
* The two dovetail plate mounts for the bottom of the telescope have to have small section removed due to bolts on the telescope which were in the way.
* Bottom dovetail plate then attached.
* guidescope rings and guidescope attached to the top plate
* counterweight attached to bottom.
* The telescope was then approximately balanced by adjusting the counterweights position on the plate and by unscrewing the counterweights so they were further from the OTA.

Please edit and put your text etc. here
---------+ Alignment of fiber horizontally and vertically
* SBIG camera for spectrometer:
* Exposure: 0.1s
* Temp: 10 deg
* Subframes
* FireWire Camera:
* records video at 30fps
* Exposure: 1/500 s
* Approximate focus was first found. set at 255 mm
* The mirror was adjusted horizontally such that the laser moved horizontally in the camera frame.
* Images were then taken of both the spectral line of the laser and the image on the FireWire camera as it was scanned, 40 images were taken.
* The maximum intensity of the beam and its position were recorded on the FireWire camera and the summed intensity was recorded for the spectrum with removal of backgorund.
* The intensity on the spectral line was then plotted against the position on the FireWire camera, this gave a plot shown below.
* The peak position on the above plot is then used to set the position of the beam on the camera, which is approximately at a position of 200 pixels.
* Once the position has been set the process was repeated scanning this time vertically, this gave a plot as shown below.
* The best position for the beam to be on the camera for max intensity at this stage is then at pixel values [200,216].
---------+ Focussing the beam
* Once the beam has been set to the best position as found earlier the camera and optical fiber were adjusted between distances of 220mm-290mm in 2mm intervals to find the best focus.
* Here the same measurements as before were made. The intensity of the spectral line and the maximum intensity of the FireWire camera are plotted against focal distance.
* The plot of both the camera and optical fiber is shown below.
* With this image the approximate best focus was set at 250mm
---------+ Repeat of alignment
* The alignment process was then repeated as before, this gave the below plots.
* These gave maxima at a pixel position of [201,217], The image below shows the position of the laser of the camera at this point:
---------+ Horizontal Scans at different Focal lengths
* For 6 different focal lengths, 240,244,248,252,256,260, a horizontal scan of the laser was recored on the camera and the spectrometer. This range was chosen as in the above focus plots, this is where the intensity flattens.
* For each of these the position of the laser of the FireWire camera was plotted against the total intensity of the fibers.
* The aim was that the focal length which gives the smallest width of a spectral line is the correct focus.
* The plot below shows the intensity plot for each of the focal lengths, and the widths of the line.
* This shows the widths does not change much in that range, this could be due to the fact that the focus is smaller than the size of the optical fiber, therefore, the integrated amplitude will remain the same in this range.
* Therefore, by selecting a single fiber to integrate the intensity over, it should be possible to find focus.
* The below plot shows the same results for a single fiber
* This shows that the width of the line drops in the range of 252-256 mm .
* by fitting a Gaussian function to both the image on the firewire camera and the plots above, the widths could be plotted against the focal length for both.
* Each of these were then fit with a hyperbola function,
* This gave parameters of,
| parameter | FireWire | Fiber |
| mean | 254.8±1.2 | 255.2±1.1 |
| a | 4.28±0.92 | 6.12±1.25 |

Saqib Hussain + Jervis Ong Arrived at 16:24, weather clear
* AA arrived 17:30
* Took example flats with both cameras
* Setup telescope, synched on Vega
* focused the telescope on a star
* took a few dark frames to distinguish dust on the telescope
* Primary observation target identified : rho Cyg- 73 Cyg - HIG 106481, right ascension = 21h 33m 58.85298s, declination = 45° 35′ 29.1 "
* Checked the camera cooler temperatures: -5.2 for ST8 and -15.0 for ST8300
* Took exposures with exposure time 0.1s for ST8300 and 0.5s for ST8
* For ST8300, file names begin with odd alphabets (a,c and so on) whereas for ST8 file names begin with even alphabets
* The data is compiled as below:
| Telescope | Exposure time/s | Time frame/minutes | No.of Images | File starts with |
| ST8300 | 0.1 | 12 | 66 | a |
| ST8 | 0.5 | 12 | 45 | b |
| ST8300 | 0.1 | 16 | 100 | c |
| ST8 | 0.5 | 11 | 45 | d |
| ST8300 | 0.1 | 9 | 45 | e |
| ST8 | 0.5 | | 45 | f |
* Moved on to collate data for atmospheric extinction
* For ST8, we tried to take images with different filters (luminescence, red, green, blue) for an exposure time of 0.4s
* However, due to technical problems we were unable to take images with colour filters
* We continued taking unfiltered images every 10 minutes (as the star moved from the azimuth to the horizon), saving them as files beginning with L
* Exposure time is 0.5s for every image
* Cooling power was within the range of 40 and 49%
* Data are as follows:
| Time | File Name |
| 2158 | L1 |
| 2208 | L2 |
| 2218 | L3 |
| 2228 | L4 |
| 2238 | L5 |
| 2248 | L6 |
| 2258 | L7 |
| 2308 | L8 |
| 2318 | L9 |
| 2328 | L10 |
| 2338 | L11 |
* took a photo of Andromeda
* Turned the coolers off, disconnected the cameras. Double checked everything was disconnected.
* Exported data into USB stick.

set up procedure
* check for damages on solar filters
* solar fillters on finders scope and main scope
* mount camrea
* use a SCT connector
* screw onto fliter and telescop
* RGB filter
* clip onto tube
* C-mount to 1.25 inch tube
* screw onto camera
* camera
* mount camera unto telescope by unscrewing the big ccd camera
* fire wire cable connected to the camera(clips in)
* with them, covered you can open the dome doors
* switch on telescope
things differe form a normal observation:
* use different type of camera( imaging source dmk 21af04.as)
* use a different piece of software
* stop the tracking
IC capture
* open IC capture
* click camear being used
* device properties click off auto gain and exposure
* check if histogram isnt saturated
* adjust exposure so it is not saturated
* saving sequnece of image
* capture -> squence settings
* file name and target, pick a directory(desktop/data/YYYYMMDD) -> index at 1
* file type BMP
* Automated sequence -> interval at 1 sec -> end sequence after 400 Frames
* capture -> sequence timer -> start timer
how to turn off tracking
* set up -> enter
* targets -> enter
* trestral or astonamical ->enter
we are going to be using 2016-11-02 data

time: 17:22 arrived in dome. ENK JT AS AC AA
remove rain cover from telescope
open doors of dome (ropes(tie up), bolts)
go onto roof and observe sky
select Capella(HIP 24608) on Stellarium
RA/Dec 5h17m57.85s / 46deg 00' 40.4''
h(capella) = LST(egham) - \alpha = 1h41m52.8s(egham) - 5h17m57.85s(capella) =-3h36m5.05s
rotate dome to correct direction
callibrate telescope - move telescope manually to point at Capella, it can then know its position on the night sky and be moved using the stellarium programme
first take caps off telescope, turn telescope on(make sure everything is plugged in and switched on,checking all leads and sockets)
telescope automatically moves towards the west)
centre capella in finder scope(scope speed 5)
Synchronise coordinates on Capella ( object -> star -> named -> Capella -> Enter (2 seconds) -> Enter to sync)
move telescope away from capella
use the go-to key to get back to capella
Move to almaaz(HIP 23416) using the hipparcus catalogue method outlined in the script
Use Hip method again to move to Betelgeuse (HIP 27989), and bellatrix (HIP 25336)
open MaxIm DL Pro 5
exposure 1 sec start poor out of focus picture
change exposure to 0.1 sec, X bin 4 continuously taking images
use knobs on scope to unlock mirror and change the focal length, simultaneously slowly moving scope to get the star in the centre of the field of view of the CCD
get star in and out of focus and take picture
calibrate telescope to set on aldebaran
use focus (4 on pad) to get good focus with microfocuser that changes the camera not the mirror
take images in different exposuresmove to fainter section of sky, star cluster near aldebaran cluster 2 shows fringe from coolingtake 10 images to find saturation around 65000 for this CCD
move to 02 Tau and found bleeding and saturation at 10s, took multiple images at different exp times (1x1 binning)
found that simple auto dark callibration was on contiunued with this then took one without this

Weather - cloudy fairly poor visibility
* set up telescope, open dome, take off caps etc
* take picture of blank space, set up guide camera also
* twilight point scope at blank space look at cooling and non cooling effects
* target is betelgeuse, use to focus and synchronise camera
* move scope to pleiades, new target in order to take pictures of cluster, image with multiple stars
* centre on atlas and pleione
* look at error in plate scale as a function of flux ALL FRAMES!!!!!!!!!!!!!!!
* f[0].header this shows all the info about the image and the telescope
* shape(d) Out[40]: (1020, 1530) dx1 = d[0:500,:].sum(0) dx2 = d[501:,:].sum(0) plot(dx1) this will set a range on the x/y axis

time 10:30am arrived in dome. A Cozens, L Lenz D Bedingham S Boogert
poor weather conitions so no solar data could be recorded
used SLR camera to take images of boiler house in order to understand how the manual settings of the camera affect images
took 30 images with different exposure times and varying the ISO number, as ISO increases smaller exposure times are required so not to saturate the image.
The images are located
C:\users\astrodome\desktop\3_data\20171018_Solar
with two files showing the dark frame images taken to show the noise of the camera with the cap on the lens and light brick images taken at different exposure times with different ISO

10:30 dome. Bedingham, Cozens, Lenz
* good weather => took a few images with Canon SLR camera
* The following settings received best results: ISO=100, exposure time=1/4s to 1/8s, max. f-number
* Used rawkit Python package to transform .cr2 files into .tiff
* Applied Hough transformation to find circles in image
* Measured brick width L with ruler and received distance D from dome to boiler house brick via Google Maps
=> L = 22cm, D=104m
* From this calculated angle to be θ = 2*arctan((L/2)/D) = 0.117° = 0.22x(angular separation of sun(0.5°))
* Next steps: - take image of smooth white background to measure the vignetting effect of camera
- adjust parameters of Hough transformation to find correct circle

use DSLR to take white images to look at the natural vignetting effects of the camera, took many exposure times so to get an unsaturated image. Need to process these to get a pixel vs intensity curve to show that the fractional ratio of intensity does not depend on exposure. Also look at different colour channels and create a plot to show all 3
Then set up the telescope so as to record data, fit with sun filters and imaging source camera. Using ICcapture software.
Use shadow of the telescope to align, and adjust further with finder scope.
set telescope to the west of the sun to see it passing through the window, takes around 1min to fully pass no data recorded
Use DSLR to take images of the sun, lowering the exposure times to find an unsaturated image. Use circle finder code to analyse the intensity array across a diameter of the sun.
Attached Text files show the image numbers on the DSLR for varying exposure times ISO=100 for targets of the sun then a white light source evenly lit for investigating the vignetting effect.

10:30 at dome, D. Bedingham, L. Lenz
* cloudy weather => took no images of Sun
* Vignetting images from last week were not symmetric
=> will have to retake those images with diffuse light (outside) and a variety of exposure times to achieve different max/min intensity values,
the ratio of I_max/I_min should be approx the same throughout
Next steps:
* Take correct vignetting images with different exposure times and diffuse light
* Analyse new vignetting images and apply curve fitting to it => V(x) => can receive real intensity with I(x)*V_max/V(x)
* Estimate unscattered intensity f of Sun images
* Fit curve to unscattered intensity => Gaußian fit => should get data back (~Gaußian curve)
* Optimise f

looking into error in blue filter images taken previously
is an error in the programme with the readout, reboots and restarts did not solve this. Updated the verison of IC Capture from 2015 model to 2017, this had some minimal effect
Look at changing the Frames Per Second to a smaller amount (from 30 to 3.75) this did correct for the oscillation problem looking at blue sky
Move to try and take images of sun again with filter
Wait for sun to be away from tree.

Weather Conditions: Clear
Time: 22:40 - 1:50
Targets: Betelgeuse & Pleiades Cluster in RBG filters
Cameras Used: SBIG ST 8XME(camera 1) and SBIG ST-8300M(camera 2)
Both cooled to -20deg
Telescope already synchronised, moved and focused on Betelgeuse. Target too bright for filters. Kept saturating.
Moved to a new target, the star, Bellatrix. Again too bright for filters.
Moved to another new target, HIP26594. 15 images taken for all three filters RBG, exposure time 1.5s.
Then moved to the Pleiades, in narrow view camera (camera 1). We took ten images in each filter with exposure time 10s. And we took ten images in each of the green and blue filters with exposure time 40s.
We switched to camera 2, a wide view that could take an image of the whole cluster. The image is inverted in camera 2. We took 20 images with exposure time 0.4s with no filter.

* set to speed 5, center
* start exposure, bin 4, continuous, center object, speed 3
* adjust focus, unlock primary mirror clockwise 2 revolutions, bracketing process(see how the object is changing), object keeps moving, brightness changes, focus as much as possible, center it again speed 3, synchronize-object,star,named, click for 2 sec
* observede diffraction pattern- something is wrong with the camera, filter plate not moving, adjusting, fixed filter changing
* change exposure time to 0.3s, get star off center, focus on other, dimmer stars, adjust focus once more to see clearly
* discovered diffraction pattern in filter image
* took apart camera with help of Prof Boogert
* once camera filter in working condition, resumed observation
* took exposures of far field stars near Betelgeuse in order to focus the telescope
* shifted focus to plaidees - Atlas and Cleo
* used Astrometry in order to determine our location in the night sky
* once Atlas and Cleo found, took 0.1 interval exposures from 1 to 5 seconds until stars were saturating pixel value
* once pixel values saturated, shifted view to m41 orions nebula
* took one 7 second exposure

15/2/18 Began: 17:30
Started up telescope & opened observatory. Connected to camera with maximdl (disabled camera 2), turned on cooler to -15.
Found Capella @ LST=3:45, h= 22:27, rotated telescope mount. Changed declination to 46 degrees. Located star in viewfinder.
Began continuous 0.1s 4x4 binning image capture of CCD view. Moved telescope (speed 1) opposite to image view due to CCD being upside down, to centre Capella.
Go-to button used, caused telescope to move way off target. Recallibrating as a result. Now LST=4:15, so h = 22:57, relocated Capella. Centered etc.
With LST 4:27, Atlas found at h=0:32. dec 24 deg 6 min.
Used astrometry.net to work out stars from unknown image 1, located area in stellarium
Moved to bright stars (i.e atlas and pleione), checked again with astrometry and stellarium. Synced to Pleione HIP 17851 SAO 76229 on both telescope and stellarium (connected to telescope)
Centred on Pleione. Tested stellarium movement to other stars.
Centred on Atlas, took multiple images at several exposure times, saturating the image individually for both bright stars.
zeroed telescope, closed up dome.
Finished 20:00

Logbook for PH3010 Solar limb darkening mini-project, initial setup meeting
Present: DB, MA, JC, HS
Order of tasks for observation of the sun:
1) DO NOT STARE DIRECTLY AT SUN. DO NOT POINT UNPROTECTED TELESCOPE AT SUN
2) Go outside dome and check that sun will not be obscured by the tree, wind thingy. If it will be, will have to wait before able to take images of sun
3) Check solar filters are not damaged. Fit solar filters to main scope (and if using finder scope, fit solar filter to that). Fit CCTV lens to camera, camera to filters, filters to telescope.
4) Open dome, move opening so that allows shadow of telescope to be seen on dome wall
5) Use the shadow of the top scope (the one secured by two sets of three prongs) to align the telescope with the sun. When the shadows from both sets of prongs overlap, the telescope is (roughly) aligned with the sun
6) If using finder scope, use to target edge of sun.
7) Use IC Capture program to view camera feed (really need to jam the cable into the back of the camera to get the pc to detect it). In device-properties can control gain and exposure settings
8) Use live camera feed to target edge of sun and focus (unlock and use know on back of telescope)
9) Change declination of telescope and monitor live camera feed. Need to find centre-line of sun. This is when any change in declination results in the suns edge moving out of frame (away from centre, only changing declination in one direction will move it out of frame - the other will move it more in frame)
10) On telescope control setup-targets-terrestrial or astronomical
terrestrial will keep telescope at fixed angle, astronomical follows objects through the sky
11) Choose filter to image with. Point telescope as closely as possible to centre of sun and view image histogram. Adjust and exposure until the image is not fully saturating (has a narrow yellow bar - the zero readings - visible) but has as full a range of values as practical.
12) Return telescope to point at edge of sun, in the centre. In IC capture go to the timed capture settings. Choose an appropriate target folder and image capture filenames, set the image type to bmp, turn the 'auto display capture' to off and set an appropriate capture interval and number of captures.
Note: Sun subtends an angle of about 0.5 degrees. Previous years have taken 405 seconds worth of images for this project.
13) capture images. Repeat step 11 onwards for another filter

* Dome entered 10am. Present: MA, JC, HS, supervised by Dr. DB
* Telescope cover removed, solar filters put on
* camera and colour filters were already attached to telescope. setup checked just to be sure
* Telescope setup reviewed+approved by DB
* Dome doors opened, telescope turned on
* Moon was still visible in sky - dome doors moved to allow viewing of it
* Moon used for focus (coarse and fine), took a couple of images of nice craters
* Moon found by (roughly) lining it up with the telescope, then with the finder scope, then with the camera image
* Dome doors moved to allow viewing of sun, telescope slewed to find sun
* telescope shadow aligned on wall behind telescope
* telescope moved to bring the two rows of knobs into alignment (i.e. telescope pointing at sun)
* Using camera feed, approximate equator of sun found at one edge
* Test images taken
* Moon and test sun images stored in focus_images folder
* Colour image sets taken.
* All image sets performed by pointing telescope ahead of suns motion and switching to terrestrial mode - motion of sun across sky then carries sun across the frame of view.
* All image sets taken over 3 minutes 10 seconds. This time determined by timing a test run of the method.
* 1 image per second taken for the length of the image set.
* Used maximum gain for all image sets. Exposure determined by manually slewing across the sun and trialling different exposures. Aim was to get as close to having maximum pixel values in the image, without actually having any maxed out pixels
* Where necessary, solar eclipse glasses were used to directly view sun e.g. to determine if clouds were obstructing the sun, or just the area around it
* Clear Filter 1:
* Gain 799, exposure 1/1000 seconds
* trees obstructing parts of image set - produces obvious errors in dataset
* Clear Filter 2:
* Gain 1023, exposure 1/4000 seconds
* Blue Filter 1
* Gain 1023, exposure 1/154 seconds
* Some obstruction of sun by clouds
* Blue Filter 2
* Gain 1023, exposure 1/154 seconds
* Still some clouds, but far fewer than with Blue Filter 1
* Green Filter 1
* Gain 1023, exposure 1/308 seconds
* Lots of clouds
* Green 2
* Gain 1023, exposure 1/308 seconds
* Even more clouds
* Red 1
* Gain 1023, exposure 1/1241 seconds
* A few false starts (so the file indexing is messed up), but managed to get a good run of images
* Was not able to perform another run with the green filter, due to increasing cloud cover
* Dome doors repositioned above door to roof and closed.
* Solar filter removed and lens cap replaced. Filter stored back in its home.
* Telescope returned to 0h0d
* NOTE: Minor mix-up with imgae file names. All image sets are stored in the appropriate folders / .zips for the colour filter used, but the some image sets use the wrong colour name in the individual image filenames. Recommend handling image sets carefully / renaming appropriately when used.

* Present JC, AD
* Began cooling at 16:45 to -12 deg C (~90%)
* Filter wheel set to Clear, Red, Green, Blue
* Centred on Capella and took GPS-fix. Encountered problem: telescope believed it was -1h RA from Capella however this offset was constant.
* Edit: This seemed to just be an issue with the coordinates read-out on the paddle.
* Centred on M35 and took 1000x0.1s exposures to focus.
* Then took 60s exposure- significant effects of moonlight on image- change target to M36 (RA/DEC: 05 37 13.8/34 09 04)
* Light pollution significantly reduced suggesting moon was indeed the source.
* took 60s and 90s exp in all filters
* moved to (RA/DEC: 05 37 31/34 07 50) and repeated.
* took dark and bias frames before finishing observation at 9:30pm.

PEC Training
Meade LX200GPS Pec Training
- Setup -> Telescope -> RA PEC -> Training
Method
- Connect to Stellarium and MaximDL
- Telescope pointed at Vega synced
- Moved to Epsilon Lyrae (epsilon_lyrae)
- Camera disconnected from MaximDL and connected to PHD Guiding
PHD Guiding keeps the star in the same position at all times allowing the PEC to be trained
Data read with PEC Editor (MyScopeShort) and saved as *.txt file for further analysis
PHD Settings
1st PEC
- RA_PEC_DATA1.TXT
- 0.2s
- Default Advanced Settings with:
- Full Frame
2nd PEC
- RA_PEC_DATA2.TXT
- 0.2s
- Default Advanced Settings but:
- Subframe
Processing Code:
- To be added
Plots for PEC Data:
Test images:
NGC6675 (Spiral Galaxy) - 1 (ngc6675_possible) and 5 min (ngc6675_definite) exposure, 2x2 Binning
M57 (Ring Nebula) - 1 min exposure, 2x2 Binning

Focus and Filters
Average filter wavelength
- Blue: 450mm
- Green: 550mm
- Red: 650mm
ST-8ME Quantum Efficiency:
- Blue: 55%
- 1.82x exposure from clear
- 60s clear -> 109s
- Green: 70%
- 1.43x exposure from clear
- 60s clear -> 86s
- Red: 75%
- 1.33x exposure from clear
- 60s clear -> 80s
Test Images
M57 - Ring Nebula
M56 - Globular Cluster
- 1x60s Luminance image
M27 - Dumbbell Nebula
- 9x60s Luminance images stacked to form a 6x60s image
- 1x109s Blue image
- 1x86s + 2x60s Green images
- 1x86s + 5x60s Red images
During the Dumbbell Nebula imaging the filters were accidentally changed due to the mouse scroll.
- Possible workarounds:
- Use autosave function to take images
- Check before taking a new single image

APIs:
* [[http://seal.web.cern.ch/seal/documents/minuit/mnusersguide.pdf][Seal Minuit]]
* [[http://iminuit.github.io/iminuit/api.html][iMinuit]]
*Performance (measured with Python %timeit() magic function):*
* PyMinuit: best of 3: 13.9 s per loop
* iMinuit: best of 3: 11 s per loop
*Conclusions:*
* iMinuit is easier to install than PyMinuit
* iMinuit is faster than PyMinuit
* iMinuit have more features than minuit (e.g. export to LaTeX and fake functions)
* Both detected and successfully minimized a 2D Gaussian on all the stars with same parameters
* PyMinuit "accidentely" fitted more Hot Pixels than iMinuit
* PyMinuit includes Simplex and Scan methods, which are not available on iMinuit
* PyMinuit is more stable - annoing bug in latest version cause segfault it limits, steps, ... are not set
Keep PyMinuit for now.

| Created: 10 Sep 2013 16:48:33 | Last Revised: 11 Sep 2013 15:49:16 | Public.PedroPaiva | Building Python on cygwin |
pre-requisite: have [[http://www.cygwin.com/][Cygwin]] installed and a GNU compiler.
Cygwin comes with python pre-installed, from there one can install new packages with:
* easy_install packageName
* pip install packageName
To use ==pip== you must install it first using ==easy_install pip==
The ==pip== method is favorable for it allows you to search, uninstall and upgrade packages easily.
==pip== guide:
* ==pip freeze== - display currently installed packages
* ==pip search packageName==
* ==pip install packageName [--upgrade]== - installs or upgrade an already installed package
* ==pip uninstall packageName== - uninstall a package
*Packages installed*
* ipython
* numpy
* scipy
* pyfits
*To be installed:*
* matplotlib
* opengl
* pyside
* pywin32 (don't support cygwin)
* pyminuit ([[http://code.google.com/p/pyminuit/wiki/HowToInstall][detailed guide]])
1 Download the required files: [[http://code.google.com/p/pyminuit/downloads/detail?name=Minuit-1_7_9-patch1.tar.gz][Minuit-1_7_9]] and [[http://pyminuit.googlecode.com/files/pyminuit-1.2.1.tgz][pyminuit-1.2.1]]
1 Extract and change to Minuit directory (under cygwin)
1 Compile Minuit with:
1 bash configure
make
make install
1 Change to pyminuit directory ( ==cd ../pyminuit-1.2.1== )
1 Build and install with: ==python setup.py install --with-minuit=/location/of/Minuit-1_7_9==

Ring Galaxy (NGC1291)
Protostar (IRAS 20324+4057) "The bizarre looking ring galaxy NGC 1291 in Eridanus.
These fairly rare types of galaxy are usually much fainter objects, but this one at "only" 33 million light years away is easily visible in modest size telescopes though the faint outer ring of material is much fainter than this.
Its strange appearance is the likely the result of a collision with another galaxy in the distant past.
20"CDK with FLI-PL6303e camera. LRGB. L: 70mins. RGB: 5/5/10mins" - Damian Peach
IRAS 20324+4057 is a Protostar in the Cygnus OB2 Association, 4,500 light-years (1,380 parsecs) away.
This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
INT: H-alpha
cyan ACS: F606W (V)

After turning telescope on, it successfully received GPS signal and did not started the usual RA movement.
The Camera was connected to Python via MaximDL
Telescope and Focuser connected to Python via the POTH Hub
Coordinates in agrement between Scope, Python and Stellarium
Target was set to be -0.1º RA from current telescope position and Python SlewToTarget was tested.
Telescope moved the right amount and stopped, both telescope and Python alerted when ready.
A second test was made with +0.5º RA. Also successfully.
Still with small (-0.1º RA/DEC and +0.5º RA) movements, Python SlewToCoordinates was tested successfully.
With the tests done, the telescope was moved to Vega via controled movements on Stellarium
Vega was inside the Camera Range, demonstrating that the Park Method works.
Vega was recentered (-0.01 on RA) and the telescope was manually synced.
During this test, movements as small as 0.003º on RA proved to have no effect whatsoever.
The next step was to test the focuser and the camera.
First, while still on continuous mode of the camera, the Python-Focuser connection was tested.
Python can read the position and move the focuser. Units are steps. 1 step = 20µm
Having confirmed that one can move the focuser with Python, Vega was taken out of focus to test if we could focus the star using a small

prin = True

POTHFocuser.Move(step)
while POTHFocuser.IsMoving:
if not prin:

*Focus movements*
* Positive -> In
* Negative -> Out
*Tests*
The data below have a significant experimental error associated with the not fixed measuring equipment.
Also, they can have errors related to a possible angle between the measuring equipment and the in-out axis therefore, the real value would differ by a factor of cos(theta)
*out*
* move(-5000) - 1.86mm
* move(-5000) - 1.80mm
* move(-5000) - 1.86mm
* move(-5000) - 1.81mm
* move(-5000) - 1.88mm
* *mean = (1.842 ± 0.031)mm*
* move(-1000) - 0.31mm
* move(-1000) - 0.40mm
* move(-1000) - 0.44mm
* move(-1000) - 0.27mm
* move(-1000) - 0.45mm
* *mean = (0.378 ± 0.076)mm*
The out movement is coherent and 5000 steps is indeed equivalent to 5x1000 steps
This give 1 step aprox 0.37µm
*in*
* move(5000) - 1.52mm
* move(5000) - 1.55mm
* move(5000) - 1.52mm
* move(5000) - 1.48mm
* move(5000) - 1.57mm
* *mean = (1.528 ± 0.031)mm*
* move(1000) - 0.21mm
* move(1000) - 0.20mm
* move(1000) - 0.15mm
* move(1000) - 0.30mm
* move(1000) - 0.18mm
* *mean = (0.208 ± 0.050)mm*
The in movement is 25 to 50% smaller than the out movement (depending on the movement size) with larger movements closer to the equivalent out.
This give 1 step being between 0.2 and 0.3µm
*Conclusions*
The execution of the above movements led to the following conclusions:
* Focuser always finishes in a 'in-movement' (e.g. asking to move out will make the focuser goes more than needed and come back about 1mm)
* This causes the isMoving check to return before the focus being ready.
* Focuser limit less than aprox 30k steps when going in.
* When close to the limit, focuser will overstep (move(5000) caused the focuser to move 2.76mm)
* Focuser isn't ready when isMoving returns False.
* There's a time gap when a second comand will be accepted but not executed.

[[http://www.newastro.com/book_new/ebook/c2d.pdf][Diffraction aids]]
---------+++ Using a Bahtinov mask to find the focus:
Based on Laurie's idea and [[http://starryvistas.net/articles/focusmask/focusmask.aspx][this article]] a set of 144 images were taken.
3 images for each of the 48 moves made by the focuser. All the movements were 'in' moves of 250 steps.
The images had a 5s exposure time and a master dark (made of 10 dark) was made and reduced from the images.
On each image, a gaussian was fitted to the brightest star (142/144 success) and the amplitude and sigma median were taken for each set of 3 images per focuser position.
The data was then plotted and assumed to be in a quadratic form. The results can be seen on the images below.
For the Sigma X values, the minimum can be found at: 4841 steps
While Sigma Y minimum is at: 5411 steps
And the Amplitude maximum at: 6804 steps
According to [[LogBookAstronomyEntry0015]], the 2000 step (aprox 600µm) difference would be more than double the depth of field for the telescope [[http://starizona.com/acb/ccd/advtheoryfoc.aspx][(287µm on a f/10)]].
A visual analysis of the graphs would suggest a minimum and a maximum for Sigma Y and the Amplitude close to 6000 steps and, visually, the image at step 5750 (image set 23) is the sharpest presenting a nice 'X' diffraction pattern produced by the Bahtinov mask.

* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* Attempted Installation of Python Canopy on personal laptop to begin data analysis but fails to install on Windows 8.0 (Attempting update to 8.1 to see if it rectifies issue) [Installed 32 bit version instead]
* Set temperature value to -07.5 deg C, left for 30 - 40 mins to stabalise.
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* For data analysis will need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.

Using Autosave feature to speed up process, Hence file format has changed to: T-10.0-001-E0001
Must go back to data taken on the 18/10/2013 and rename files for consistancy -> Done.
Proceeded to take another 120 dark frames at -7.5 degrees, as with coolers on 100% sensor temp would not go below -10.6 degrees.
Proceeded to take anothe 120 dark frames at -2.5 degrees.
CCD will then be reset to 0 degrees, and frames will be taken every 30 seconds as it is cooled from 0 to -10 degrees. The exposure time will be 2 seconds. Due to lack of time this will be postponed until next week.

---------+ Project meeting on 24 / 10 /2013
Present: Chris Haynes, Paul Hallam, Ryan Cheale, Dr Boogert, Professor Cowan.
Continued discussion on taking and analysis of dark frames.
Due to the dome not being cold enough during the day, it is difficult to cool the camera down to -15 or -20 celcius. Therefore, the remaining readings will be taken further into winter, when the dome is colder.
Objectives for analysis of dark frames:
* Plot a histogram of the -5°C, 60 second frame and compute the mean, median and standard deviation.
* Plot the column mean and consider the standard deviation for all columns.
* Plot the standard deviation as the square root of the mean and check to see if it's a Poisson Distribution.
Additionally, we should think about the dark current rate (the rate at which an electric current is generated in the chip due to the production of electrons and holes) and how to compensate for it.
We should also consider what the faintest star we could detect would be, looking at the point spread function of our telescope.

---------+++ Activity Log
* Took off cover for telescope & Camera
* Turned on Camera and followed steps detailed [[Students.UnderGraduates.RyanChealeCameraTechnicalAspects][here]]
* Set temperature to -10 deg C, waited 30 - 40 mins for stable temperature
* Used Autosave Sequence located at 'Desktop/Data/20131016_RC/25darks60s.seq'
* Autosave feature allows running of each permutation whilst saving automatically
* Format T-tt.t - NNN - Eeeee.fit where T - temperature, t - temperature value, N - repetition (==20) , E - Exposure, e- Exposure time value (0.1s, 1s, 5s, 10s, 60s, 180s)
* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* turned off the coolers on the camera to allow it to reutn to room temperature.
* Proceeded to take data in 30s intervals for 30mins whilst turning the coolers back on and allowing the temperature to reduce to -10 deg C to see what effects allowing the temperature to stabalise has
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* For data analysis still need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.
Python
* Began the use of the canopy environment to begin data analysis in Python.
* Running into multiple problems with the canopy environment with plotting graphs
* Have made plots for the mean, standard deviation, max and min values of the data set T-05.0-NNN-E0600
* Struggling to create histogram plots, either the kernal or the environment tends to crash when trying to create a histogram of a single fit file
* Next steps:
* Produce median plots
* Refine code so only needs slight input alteration for other data sets
* Produce histograms and then further plots based off of the histograms
* begin analysis on cool down data.

A study into the variation of background pixel count with temperature.
Initial CCD temperature was recorded to be 18 degrees. Coolers were turned on and CCD cooled to 0 degrees over the course of an hour, to ensure the entirety of the CCD began at zero degrees for the following study.
Coolers were then set to cool the CCD to -10 degrees, and one second exposures were to be taken every 30 seconds for one hour over this cool down period.
The data shall be saved in the following format: Cooler_Study-001E001
Also this shall also provide 29s exposures between the 1s exposures, which shall appear like this: Cooler_Study-001E029. This data will not be analysed.
When this collection of data has been finished, CCD was at a constant -10 degrees. The CCD coolers were switched off, and the CCD warmed back up to room temperature. Using the same method, one second exposures was taken every 30 seconds for one hour over this period.
The data shall be saved in the following format: Cooler_Study_2-001E001
Again this will also produce data that will not be analysed, in the form of: Cooler_Study_2-001E029
Room temperature in this case is 25.6 degrees.

---------+++ Telescope Set Up
* Target Delta Cephei selected using Stellarium and AAVSO catalogs
* Open shutters (ropes, pull apart, tie off ropes, motor control
* Turn power on
* Press power switch on telescope
* Removelens caps
* Point towards Vega
* Line up with finer scope
* Take continuous frames 0.1s
* Center Vega in frame
* Synchronise Vega with Maxim DL and Stellarium
---------+++ Target Information
* Pulsating Variable star, magnitude variation 3.5 - 4.4, Δm = 0.9
* Period 5.4 days
* Next maximum, 07/12/2013, 9:32
* RA: 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From simulated light curve - expected Δm(max) = 0.26, expected Δm(min) = 0.01
* From light curve of Delta Cephei, and time of next maximum, we believe the magnitude should be decreasing
* Companion star HIP 110988 used as a reference star
---------+++ Initial Observation of Delta Cephei
* Centered on Delta Cephei - did not use Stellarium as could move telescope through the pole
* Frames were taken using different filters, initial exposure times:
* No filters - 1s
* Blue filter - 10s
* Green filter - 3s
* Red filter - 3s
* Took sample frames using this-set up, max pixel count was found using Python
* Re-evaluate exposure time to ensure max pixel count was in the range 55000 - 60000
* Re-evaluated exposure times:
* Focus filter - 1.1s
* No filter - 1s
* Blue filter - 10s
* Green filter - 5.1s
* Red filter - 3.3s
* Decided to take 5 repeats for each of these, and 10 repeats for Dark and Bias frames
* Autosave feature was used to take a sample set of data
* Residual image of Star found on Dark frames - low pixel count
* Implemented a 'Trash' frame before the Dark frame to attempt to remove this -> some residual image still remained
---------+++ Observation of Delta Cephei
* Autosave feature took approximately 10 - 15 minutes to run
* Approximately three runs were taken per hour
* Delta Cephei was observed for 5 - 6 hours
---------+++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope
* Turn off camera
* Turn off telescope
* Put cover back on camera
* Close dome shutters
* Turn off PC monitors
* Turn off lights and leave dome

20140213 LN
Reasonably clear and forecast to be good. Worth a try to get some practice in.
* CCD at -15oC
* Aligned to capella - very high in sky.
* Went down from 46 to 37 DE to theta_aur as capella saturates the camera.
* Take subframes to practice focussing. Recorded 400 frames of theat_aur for analysis later. SNR is good as super bright. Peak around 30000 ADU. Jumps around A LOT so will have to align by centroid. Then can have a look at PSF.
* Exposure 0.1s
* 300 exposures recorded in 10m12s
* 400 exposures recorded in 13m37s *Sat bhatinov mask carefully on front of scope. Recorded 50 images with same setup as before. Not so clear.
* Exposure 0.5s
* Not so clear. Pattern seems very small indeed on CCD compared to internet images. Collimation is definitely poor and its windy so don't expect it to be great. Anyway, reasonably good in focus.
* Having a look at the Pleiades. Too extended to see anything nice and certainly with the seeing. The stars are very bright and the nebulosity not so, so quite hard to observe under these conditions.
* Imaged Andromeda ok. 30s exposures.

Using the spectrometer to find the brightest spectral line in mercury and Find the best micrometer reading for the angle of the camera.
Camera was ST-7E, Setup SBIG Universal.
Temperature for all the images was -6.5 deg C.
*Focus*
Exposure time: 0.1s; Grating distance 1.814mm; Camera angle micrometer reading 2.495 (heavily sloped)
Used continuous range to find a reasonable staring point.
Used range of 18mm to 20.5 mm in steps of 0.5
Reduced range to 19mm to 20.5mm in steps of 0.10
Reduced range further to 19.50mm to 19.80mm in steps of 0.05
*Camera Angle*
Exposure time: 0.1s; Grating distance 1.814mm; Focus distance was 19.60mm for this
Used continuous range to find staring point.
Used range of 2.50mm to 5.50mm in increments of 0.5mm to start.
Reduced range to 4.00mm to 5.00mm in steps of 0.10mm
Reduced range further to 4.45mm to 4.65mm in steps of 0.05mm
Found the best angle to be _4.60mm_
*Brightest Peak Data*
Looking through the spectrum the brightest peak, found at 4.00mm in grating micrometer.
This was saturated so the lamp was moved back by 5cm which was still saturated, then we moved it back by another 5cm which put the lamp back from the optical fibre by 25cm. This reduced saturation where refocus was done. Seemed to saturate at 50,000 confirming it was brightest peak.
Used this to check the focus and recalculate.
used a range from 19.50mm to 20.50mm in steps of 0.10mm
Found best focus distance on micrometer to be _20.10mm_

27th Oct 2014 Msc Observation.
*Begun:* 18:30
*Finished:* 22:30
Conditions: Mostly clear, a little muggy. No cloud coverage.
Begun observation session with a run down of the procedure to prepare the dome.
*Dome Procedure:*
-
Enter dome
- Close the hatch to prevent heat rising and entering the dome. The floors beneath are heated which causes a ‘chimney’ like effect if the hatch is left open as the hot air from below will rise up through it. Ideally the scope and dome should remain cool so noise due to thermal fluctuations is kept to a minimum.
- In the Maxim DL suiteconnect to the telescope. This allows control of the camera for example you can set exposure times and capture images from the program.
- Enable the CCD cooler in Maxim. This should be done ~1 hour before taking exposures. If you take observations too soon after enabling the cooler you get a ring like effect on your observations around the outer area of the frame. The ring progresses further to the sides of the frame as the CCD cools until it eventually disappears.The set-point of the cooler is set to -10 degrees celcius and the CCD itself fluctuated around this point slightly once the cooler had taken full effect.
- Untie the ropes that control the shutter of the dome. Pull on ropes to open the shutter of dome, if the shutters do not open with ease, there is a long stick with a metal prod at one end which can be used to manually push the shutters open from near the top of the dome.
- Once shutter is open, tie the ropes off again to make sure that they are kept out the way of the moving parts of the done which can rotate bothe counter and clock-wise
- Using the door on side of dome, go outside and do some preliminary naked eye observations to find an interesting object to observe (this is important for aligning the telescope as detailed later on). This allows you to plan roughly where the telescope and open shutter should be pointing to allow unrestricted viewing.
- Using the dome control unit, align the dome opening with what you want to observe.
- When finished observing, realign both the dome and telescope to their origional position. Close the dome shutters and tie up the ropes.
To begin making observations you need to align the telescope to a bright object in the sky and then enable tracking. Tracking corrects the position of the telescope relative to the sedereal motion of the stars. This is necessary because the field of view of the telescope is so narrow if it was left stationary, the object you are observing will move out of frame. To align the telescope, the first step is to identify a bright object visible to the naked eye in the nights sky. You can acess the roof from the dome via. the door on the side. Once on the roof you are able to evaluate potential targets. We identified the star Vega (25ly away, 2.1M0, alpha lyrae - the brightest star in the lyra constellation and 5th brighest in the night's sky). The star charts provided in the program stellarium coupled with manual positional measurements allow you to identify the star you are looking at with the naked eye.
Once a object in the sky has been chosen, the next step is to align the telescope to enable the activation of tracking.
- *Telescope Alignment:*
-
Use a high speed on the control paddle (speed button -> 9 is fastest, 1 is slowest on number pad) to crudely align the scope with what you want to observe using the arrow buttons. This can be done roughly by eye by lining up the two bolts on the side of the telescope with what you are looking for.
- Then use the viewfinder which has a set of crosshairs to align the scope more accurately with the object in the sky. A medium speed setting on the paddle can be used to move the scope with a greater deal of precision.
- Once the crosshairs are centred on the object you wish to view, take an exposure in the maxim DL suite. Once the image has been taken and downloaded you can adjust the scope to get the object centred in the frame. If you set maxim DL to take continuous ~1s exposures you can get a better sense of the best way to align scope and object.
- Once the scope is aligned, enable GPS lock. This continuously corrects the scope to account for the rotation of the earth. The field of view of the scope is very narrow causing the object you are observing to move through the frame if the scope remains stationary.
- Once tracking is enabled, the scope should keep the object you are trying to view in frame automatically.
- Using the control paddle, tell the telescope which star/object it is currently aligned to
- With the telescope connected to stellarium which now allows you to control the scope through the program itself. Using the star charts, you can align the scope to stars/objects shown in stelarrium. (Wait for the ‘beep’ if you move the scope in the program. The scope moves quickly at first but then makes finer corrections to ensure the scope is aligned well. The 'beep' occurs once the telescope is properly aligned, it can take some time ~20-30 secs).
- While repositioning the telescope it is important to be aware of it's orientation with respect to it's base. The telescope is capable of flipping over on itself which can cause the CCD attatchment to collide with the stand. In a situation where this may happen, power down the telescope via the power controls located on its stand immediately.
With the telescope aligned you can control where it is looking via. the stellarium program. Multiple exposures of Vega were taken at different exposure lengths using the Maxim DL program.
Using stellarium, the telescope was then trained on the open cluster M-39 in the constellation cyganus (800ly away from earth). Again took multiple exposures. The cluster is composed of a number of stars. Using the star chart in stellarrium the star patterns were compared to that shown in the exposure allowing for individual identification of the stars the cluster is made up of.
You have the ability to manually focus the telescope. If it is out of focus the exposures of stars can present as donuts (dark centres with bright outer ring) or they seem flat and blurred at it's edges. The procedue to manually focus the telescope is first to 'unlock' the mechanism. There are two dials, the shorter one can be rotated to unlock the device allowing the second longer dial to be turned focusing the telescope.
Last target of the night was the andromeda galaxy known as M-31 (as it is a messier object) and is 2.5x106 ly away from earth and the closest spiral galaxy to the milky way group. This galaxy has a mass ~ 1.5x10^12 M0. 10 exposures were taken one after the other with the intention of eventually using them to form 1 image with considerably less noise.
An interesting point to note is that movement of the atmosphere above the telescope can cause exposures to shift in and out of focus. This was made evident as during continuous exposures of M-39, the stars were alternating between being in focus and out of focus.
The exposures taken during the night of observation are attached to this post.

*Observations of the Spectrum of Betelgeuse*
Started looking at Capella. Using a small sheet of tracing paper to allign the star in the optic fibre coupling. With Capella at a high Altitude we switched to Betelgeuse as a target to make allignment easier.
Viewed Capella at
5hrs 20' 30'' RA
45deg 8' 2'' DEC
with the micrometer at Grating-4mm, Angle-3.25mm, Focus 20.2mm.
changed the RA 5'' either side to align it centrally while observing the intensity recieved.
*Betelgeuse*
Next look at Betelgeuse,
5hrs 58' 32' RA
6deg 25' 30'' DEC
Took a 30s exposure at 4mm to look at the spectrum as best as possible. Then took 60s exposures of Betelgeuse between 0mm and 10mm in steps of 0.5mm.
After Betelgeuse we briefly moved to the Orion nebula however it was too dim to observe.
*Pollux*
7hrs 46' 14'' RA
27deg 59' 18'' DEC
Again took 60s exposures from 0mm on the grating position micrometer too 10mm in steps of 0.5mm.
Laurie left at 23:00
*Castor*
7hrs 35' 22'' RA

Please edit and put your text etc. here
Start Time: 19:00
Conditions: Slightly cloudy at start, quickly became clear around 8pm and remained clear.
Observations:
*Castor (Alpha Gem)*
Aligned to Castor, RA: 7h 34m 35.87s, Dec: 31dg 53' 17.82" Apparent Mag: 1.93
Ring visible due to cooling of CCD chip taking place.
*Near Castor*
Observed multiple stars near Castor with low magnitude (10 - 15)
No images taken.
Ring still visible.
*NGC2388*
Centred on galaxy NGC2388, Apparent Mag: 14.
NGC2388 was chosen as a target as it is known to currently contain a Supernaova of Apparent Magnitude 15. See http://www.rochesterastronomy.org/snimages/snactive.html
Supernovae: PSN J07285387+3349106, RA: 07:28:53.87, Dec: +33:49:10.6, z = 0.013790
One frame was taken at 120s exposure. Stars were cross checked with Stellarium and were found to be low magnitude (10-16). Two other galaxies were also clearly visible, NGC2385 and NGC2389. The cooling ring was still visible at the edges of the frame. This location was chosen for the target of this observation due to the number of low magnitude stars, and the presence of three galaxies.
Uploaded a frame to astrometry.net
Experimented with 180s exposure, decided to use 120s.
Stacked frames using MaximDL built in image stacker to invstigate noise reduction.
Images taken:
Data was taken in bursts of 9 images, 3 Light Frames with 120s exposure, 3 Dark Frames at 120s exposure and 3 Bias frames.
Dome was realigned every 2 bursts to ensure unobstructed view of the sky.

---------+ 2015 05 20 LN DSLR Observation
* Trying out DSLR on back of scope
* Benefit - easy live video to investigate focussing, wide field of view
---------++ 20:30 start
* Dismounted SBIG camera (in case)
* Canon DSLR bayonet adapter + BADER 2" - T/2 Nosepiece on back of micro-focuser
* Observed Moon, Venus & Jupiter during twilight ~ 21:40
* Aligned & synchronised to artturus star to the south as visible to the naked eye
* image of M3 globular cluster ~ magnitude 6 - can make out ok in photos but still blue sky background as still slightly light
* 2155
* Trial of Deep sky object - still lightish but will keep iterating over objects
* Bodes Nebula mag 6.9
* Of note is that the DSLR is slim enough for a polar flip of the mount. Haven't, but can.
* Whirlpool Galaxy
* Getting better images but can only really see core of galaxy - still to much sky glow
From images of a single bright star or say of Jupiter and it's moons, you can see what appears to be both coma and chromatic aberration. The edges of non-point like objects have an orange tinge on one side and a blueish tinge on the other. Jupiter is relatively low just now so there is a strong affect from the atmosphere / imaging but still Jupiter had an asymmetric tinge. The moons were also quite distorted. Although the 'live view' gives you some indication, it simulates the exposure settings and can distort the image a little. Best to take images directly and zoom in to compare. Not too different from live view though.
* Telescope likely needs collimation, but the trouble is finding a good enough night for to be able to observe any improvement.
Sky much darker now. While no clouds around, there is a bit of haze - can't see huge multitude of stars.
* Starting at 3845 images of great cluster in hercules.
Finish at 22:20

---------++ *Before taking data*
* Time of turn on: 18.20.
* Cooler set to -7 degrees.
* Temp at -6.9 degrees at 18.30.
* Center the telescope on Vega.
* Aling the telescope to Vega. (~Mode on the controller)
* Speed 5 and later 3 on controller while focusing on Vega.
* Microfocuser used to fine focus.
* Speed 3 to place Vega in the center of the image.
---------+++ Alpha Persei Cluster (Cr 39, Mel 20)
* We chose our cluster as the Alpha Persei cluster.
* To focus on the cluster we chose a nearby bright star Mirphak.
* We used it to correct our ofocusing and we synched Stellarium wityh the telescope.
* We choice a patch of the cluster (HIP16001) and took 10 vimages of 10 second exposures. ( x binning set to 1, x anmd y originally inverted, this was reversed)
* 5 bias frames and dark frames of 5 1min exposure.
* Took 3 40 s red.
* Took 3 40-s gtreen.
* Took 3 90 s blue.
*
* Move to a different patch (around RA:3h29min29s, DEC:49deg44'16")
* Ian joined us at 20:00
* 3 images of 60s visual.
* 3 images of 120s red.
* 3 images of 120s green.
* Finished taking data at 8.30 pm.
---------+++ Dark and bias frames
* Started taking dark frames. 5 images of 120s.
* Take 10 bias aswell.
Observation finished at 8.56pm.

The aim of the session was to modify the parameters of the camera. Using only OpenCv it was impossible to set the camera's parameters with known units.
py-ic-imaging-control was downloaded from: https://github.com/morefigs/py-ic-imaging-control
py-ic-imaging-control is a python wrapper for the IC imaging control software development kit from the imaging source (TIS). It provides control to TIS cameras, and can serve as an alternative to using OpenCv to access the cameras parameters.

The DMK camera was fixed to a tripod and pointed at the moon.
Run1: Gain set to 180 and images were recorded of the moon at a frame rate of 7.5 frames per second. The algorithm left the exposure setting on 1 as the image was not over or under exposed on this setting.
Run2: Gain was increased to 1023. The images were over exposed and the algorithm accounted for this by changing the exposure setting in increments of 1. It was noted that this was very slow to respond to large and sudden changes in conditions.
Run3: The code was modified such that the amount the algorithm changed the exposure setting depended on the number of pixels that were saturated. This massively decreased the time the algorithm took to find the correct exposure setting. See screen shot.
Images were also taken of Orion's Nebula, see image file names for parameter settings.

Az/Alt: 318deg 44'20''/38deg34'50''
Took testing pictures: Cooling_1 and cooling_2, can be seen a ring surrounded by the ice. Secong image shows larger ring, meaning hte camera is cooling down
Cooling_3 image is clear and even
Checked the wether with met office, clouds are exopected to clear for the rest of the night
Finding the star by eye, alighning the tescope, using stllarium found it was Procyon
As it wasn't clear that the star is Procyon, checked with Rigel
Took images of the delta cep with no filter and with filters: red, green, blue and spectroscope. Aimed for 50 000 pixel value - the closest to the maximum possible p.v.
Exposure time was increased as different filters were applied, because different filters obsurb more light.
Cloudy weather led to taking many pictures for blue filter with longer exp time, 16 sec.

Please edit and put your text etc. here
---------+ Finding focus of optical fibre
* The focus of the optical fibre was found by taking a relative distance between the lens and the position of the optical fibre, and measuring the amplitude of a spectral line from the laser found at 3.5mm.
* taken at 1mm intervals between 230m and 270mm.
* Fit with hyperbolae as approximation
* distance measured with ruler so very approximate i.e ±1mm
* Best focus was found at 250mm±2mm
* Iris was almost closed as the laser would saturate camera at shortest exposure.
* also took more data as SBIG ST-7E was cooling.
* Just need extra part to connect firewire camera, so that the alignment can be competed.

Please edit and put your text etc. here
---------+ Focussing Beam Splitter
* To find best focus should be able to focus onto a single fibre, once one illuminated, in focus. will have to use extension rings for optical fibre.
* CCD camera can then be adjusted until in focus.
* Focus by shifting backwards and forwards on rails.
* Find focus of camera with max intensity and minimum width of laser.
* Use diffuser or neutral density filter, will need neutral density filter.
* Make two plots of intensity on camera and fiber and adjust until peaks overlap.
* Such that there are two plots which look similar to:
---------+ Aligning Beam Splitter
* Align by moving the mirror horizontally and vertically until maximum intensity
* possibly get 3 more irises, to control aperture at camera, fibre and entry, to make sure always have good alignment.
* As now in focus, can scan around fibres and find the relative positions compared to the end where they are arranged into line.
* This could help with finding best position of ray on camera
* Look up mirror and see how much change in angle before lost fibre, one full turn until laser out of view.
* try to get two irises as far away from each other for best alignment.
* once part for CCD arrives, move around and find relative positions on camera to positions on optical fibre.
---------+ Relating to telescope
* Have to use larger beam size so that f# is the same as the telescope, f# = 10,
* currently 3 dioptre lens, so 1/3 m focal length, this means need a beam diameter of 33.3 mm or a longer focal length.
* as , where f is the focal length, d is the diameter of beam or aperture and f# is the f number.
* consider which camera to be used.
* beam splitter reflects 30% and transmits 70% so check this.
---------+ testing intensity
* tested the intensity at reflection and transmission, with diffuser and tissue in front of laser, tissue made intensity vary substantially so averaged over five frames, the reflection intensity was found to be 3% of the transmission intensity, however there could be problems with focus and alignment at the refection, need better analysis of this.

---------+ Aligning Camera and optical fiber
* Spectrum images,
* Exposure: 0.1s
* Temp: 10 deg
* used subframes around spectral to speed up
* FireWire camera * Exposure: 1/500 s
* The FireWire camera was attached to the beam splitter and connected to IC capture
* Optical fiber was attached using a spacer to approximate the same focal length as the FireWire CCD
* Initially an approximate focus was found on the FireWire camera.
* Then the angle of the mirror was adjusted vertically such that the laser beam was scanned vertically.
* images of the position on the CCD and the spectrum were taken at a range of positions.
* The amplitude of the spectral line was then recorded with position on the CCD.
* This gave a plot shown below for the maximum intensity. i.e centre of fiber
*
* This was then repeated for a scan horizontally, which gave the plot below.
* The best positions were found to be at [190,218] pixels, i.e 190 pixels across and 218 pixels down
* The the focus of the image was to be found.
* The box which the beam splitter and camera is attached to was placed on the rails and scanned backwards and forwards using a ruler for approximate focal length.
* Images were recorded for both the camera and optical fiber, and the amplitudes were plotted against focal length.

Please edit and put your text etc. here
---------+ Alignment of Camera and Optical Fiber
* SBIG camera,
* Temp: 10deg
* Exposure: 0.1s
* subframe around fibers
* FireWire Camera,
* Exposure: 1/500 s
* Took focus measurements first by moving beam splitter to find best focus.
* Best focus was found by subtraction background of spectral line image and summing pixels
* Best focus for image was found by finding max pixel value
*
* The optical fiber focussed ~6mm from the FireWire camera
* Optical fiber was adjusted such that it is as far out as possible using the smallest spacer, and the camera was adjusted so that it was as close to the beam splitter as possible.
* This was to close the 6mm gap found earlier
* The fiber and camera were then realigned as the FireWire camera will have been rotated slightly and moved out of alignment.
* Both horizontal and vertical alignment were used and the best positions were found at maximum intensity the same as for the focus.
*
---------+ Attachment of guidescope
* Two mounts for the dovetail plates attached on the top of telescope, plate then attached.
* The two dovetail plate mounts for the bottom of the telescope have to have small section removed due to bolts on the telescope which were in the way.
* Bottom dovetail plate then attached.
* guidescope rings and guidescope attached to the top plate
* counterweight attached to bottom.
* The telescope was then approximately balanced by adjusting the counterweights position on the plate and by unscrewing the counterweights so they were further from the OTA.

Please edit and put your text etc. here
---------+ Alignment of fiber horizontally and vertically
* SBIG camera for spectrometer:
* Exposure: 0.1s
* Temp: 10 deg
* Subframes
* FireWire Camera:
* records video at 30fps
* Exposure: 1/500 s
* Approximate focus was first found. set at 255 mm
* The mirror was adjusted horizontally such that the laser moved horizontally in the camera frame.
* Images were then taken of both the spectral line of the laser and the image on the FireWire camera as it was scanned, 40 images were taken.
* The maximum intensity of the beam and its position were recorded on the FireWire camera and the summed intensity was recorded for the spectrum with removal of backgorund.
* The intensity on the spectral line was then plotted against the position on the FireWire camera, this gave a plot shown below.
* The peak position on the above plot is then used to set the position of the beam on the camera, which is approximately at a position of 200 pixels.
* Once the position has been set the process was repeated scanning this time vertically, this gave a plot as shown below.
* The best position for the beam to be on the camera for max intensity at this stage is then at pixel values [200,216].
---------+ Focussing the beam
* Once the beam has been set to the best position as found earlier the camera and optical fiber were adjusted between distances of 220mm-290mm in 2mm intervals to find the best focus.
* Here the same measurements as before were made. The intensity of the spectral line and the maximum intensity of the FireWire camera are plotted against focal distance.
* The plot of both the camera and optical fiber is shown below.
* With this image the approximate best focus was set at 250mm
---------+ Repeat of alignment
* The alignment process was then repeated as before, this gave the below plots.
* These gave maxima at a pixel position of [201,217], The image below shows the position of the laser of the camera at this point:
---------+ Horizontal Scans at different Focal lengths
* For 6 different focal lengths, 240,244,248,252,256,260, a horizontal scan of the laser was recored on the camera and the spectrometer. This range was chosen as in the above focus plots, this is where the intensity flattens.
* For each of these the position of the laser of the FireWire camera was plotted against the total intensity of the fibers.
* The aim was that the focal length which gives the smallest width of a spectral line is the correct focus.
* The plot below shows the intensity plot for each of the focal lengths, and the widths of the line.
* This shows the widths does not change much in that range, this could be due to the fact that the focus is smaller than the size of the optical fiber, therefore, the integrated amplitude will remain the same in this range.
* Therefore, by selecting a single fiber to integrate the intensity over, it should be possible to find focus.
* The below plot shows the same results for a single fiber
* This shows that the width of the line drops in the range of 252-256 mm .
* by fitting a Gaussian function to both the image on the firewire camera and the plots above, the widths could be plotted against the focal length for both.
* Each of these were then fit with a hyperbola function,
* This gave parameters of,
| parameter | FireWire | Fiber |
| mean | 254.8±1.2 | 255.2±1.1 |
| a | 4.28±0.92 | 6.12±1.25 |

Saqib Hussain + Jervis Ong Arrived at 16:24, weather clear
* AA arrived 17:30
* Took example flats with both cameras
* Setup telescope, synched on Vega
* focused the telescope on a star
* took a few dark frames to distinguish dust on the telescope
* Primary observation target identified : rho Cyg- 73 Cyg - HIG 106481, right ascension = 21h 33m 58.85298s, declination = 45° 35′ 29.1 "
* Checked the camera cooler temperatures: -5.2 for ST8 and -15.0 for ST8300
* Took exposures with exposure time 0.1s for ST8300 and 0.5s for ST8
* For ST8300, file names begin with odd alphabets (a,c and so on) whereas for ST8 file names begin with even alphabets
* The data is compiled as below:
| Telescope | Exposure time/s | Time frame/minutes | No.of Images | File starts with |
| ST8300 | 0.1 | 12 | 66 | a |
| ST8 | 0.5 | 12 | 45 | b |
| ST8300 | 0.1 | 16 | 100 | c |
| ST8 | 0.5 | 11 | 45 | d |
| ST8300 | 0.1 | 9 | 45 | e |
| ST8 | 0.5 | | 45 | f |
* Moved on to collate data for atmospheric extinction
* For ST8, we tried to take images with different filters (luminescence, red, green, blue) for an exposure time of 0.4s
* However, due to technical problems we were unable to take images with colour filters
* We continued taking unfiltered images every 10 minutes (as the star moved from the azimuth to the horizon), saving them as files beginning with L
* Exposure time is 0.5s for every image
* Cooling power was within the range of 40 and 49%
* Data are as follows:
| Time | File Name |
| 2158 | L1 |
| 2208 | L2 |
| 2218 | L3 |
| 2228 | L4 |
| 2238 | L5 |
| 2248 | L6 |
| 2258 | L7 |
| 2308 | L8 |
| 2318 | L9 |
| 2328 | L10 |
| 2338 | L11 |
* took a photo of Andromeda
* Turned the coolers off, disconnected the cameras. Double checked everything was disconnected.
* Exported data into USB stick.

set up procedure
* check for damages on solar filters
* solar fillters on finders scope and main scope
* mount camrea
* use a SCT connector
* screw onto fliter and telescop
* RGB filter
* clip onto tube
* C-mount to 1.25 inch tube
* screw onto camera
* camera
* mount camera unto telescope by unscrewing the big ccd camera
* fire wire cable connected to the camera(clips in)
* with them, covered you can open the dome doors
* switch on telescope
things differe form a normal observation:
* use different type of camera( imaging source dmk 21af04.as)
* use a different piece of software
* stop the tracking
IC capture
* open IC capture
* click camear being used
* device properties click off auto gain and exposure
* check if histogram isnt saturated
* adjust exposure so it is not saturated
* saving sequnece of image
* capture -> squence settings
* file name and target, pick a directory(desktop/data/YYYYMMDD) -> index at 1
* file type BMP
* Automated sequence -> interval at 1 sec -> end sequence after 400 Frames
* capture -> sequence timer -> start timer
how to turn off tracking
* set up -> enter
* targets -> enter
* trestral or astonamical ->enter
we are going to be using 2016-11-02 data

time: 17:22 arrived in dome. ENK JT AS AC AA
remove rain cover from telescope
open doors of dome (ropes(tie up), bolts)
go onto roof and observe sky
select Capella(HIP 24608) on Stellarium
RA/Dec 5h17m57.85s / 46deg 00' 40.4''
h(capella) = LST(egham) - \alpha = 1h41m52.8s(egham) - 5h17m57.85s(capella) =-3h36m5.05s
rotate dome to correct direction
callibrate telescope - move telescope manually to point at Capella, it can then know its position on the night sky and be moved using the stellarium programme
first take caps off telescope, turn telescope on(make sure everything is plugged in and switched on,checking all leads and sockets)
telescope automatically moves towards the west)
centre capella in finder scope(scope speed 5)
Synchronise coordinates on Capella ( object -> star -> named -> Capella -> Enter (2 seconds) -> Enter to sync)
move telescope away from capella
use the go-to key to get back to capella
Move to almaaz(HIP 23416) using the hipparcus catalogue method outlined in the script
Use Hip method again to move to Betelgeuse (HIP 27989), and bellatrix (HIP 25336)
open MaxIm DL Pro 5
exposure 1 sec start poor out of focus picture
change exposure to 0.1 sec, X bin 4 continuously taking images
use knobs on scope to unlock mirror and change the focal length, simultaneously slowly moving scope to get the star in the centre of the field of view of the CCD
get star in and out of focus and take picture
calibrate telescope to set on aldebaran
use focus (4 on pad) to get good focus with microfocuser that changes the camera not the mirror
take images in different exposuresmove to fainter section of sky, star cluster near aldebaran cluster 2 shows fringe from coolingtake 10 images to find saturation around 65000 for this CCD
move to 02 Tau and found bleeding and saturation at 10s, took multiple images at different exp times (1x1 binning)
found that simple auto dark callibration was on contiunued with this then took one without this

Weather - cloudy fairly poor visibility
* set up telescope, open dome, take off caps etc
* take picture of blank space, set up guide camera also
* twilight point scope at blank space look at cooling and non cooling effects
* target is betelgeuse, use to focus and synchronise camera
* move scope to pleiades, new target in order to take pictures of cluster, image with multiple stars
* centre on atlas and pleione
* look at error in plate scale as a function of flux ALL FRAMES!!!!!!!!!!!!!!!
* f[0].header this shows all the info about the image and the telescope
* shape(d) Out[40]: (1020, 1530) dx1 = d[0:500,:].sum(0) dx2 = d[501:,:].sum(0) plot(dx1) this will set a range on the x/y axis

time 10:30am arrived in dome. A Cozens, L Lenz D Bedingham S Boogert
poor weather conitions so no solar data could be recorded
used SLR camera to take images of boiler house in order to understand how the manual settings of the camera affect images
took 30 images with different exposure times and varying the ISO number, as ISO increases smaller exposure times are required so not to saturate the image.
The images are located
C:\users\astrodome\desktop\3_data\20171018_Solar
with two files showing the dark frame images taken to show the noise of the camera with the cap on the lens and light brick images taken at different exposure times with different ISO

10:30 dome. Bedingham, Cozens, Lenz
* good weather => took a few images with Canon SLR camera
* The following settings received best results: ISO=100, exposure time=1/4s to 1/8s, max. f-number
* Used rawkit Python package to transform .cr2 files into .tiff
* Applied Hough transformation to find circles in image
* Measured brick width L with ruler and received distance D from dome to boiler house brick via Google Maps
=> L = 22cm, D=104m
* From this calculated angle to be θ = 2*arctan((L/2)/D) = 0.117° = 0.22x(angular separation of sun(0.5°))
* Next steps: - take image of smooth white background to measure the vignetting effect of camera
- adjust parameters of Hough transformation to find correct circle

use DSLR to take white images to look at the natural vignetting effects of the camera, took many exposure times so to get an unsaturated image. Need to process these to get a pixel vs intensity curve to show that the fractional ratio of intensity does not depend on exposure. Also look at different colour channels and create a plot to show all 3
Then set up the telescope so as to record data, fit with sun filters and imaging source camera. Using ICcapture software.
Use shadow of the telescope to align, and adjust further with finder scope.
set telescope to the west of the sun to see it passing through the window, takes around 1min to fully pass no data recorded
Use DSLR to take images of the sun, lowering the exposure times to find an unsaturated image. Use circle finder code to analyse the intensity array across a diameter of the sun.
Attached Text files show the image numbers on the DSLR for varying exposure times ISO=100 for targets of the sun then a white light source evenly lit for investigating the vignetting effect.

10:30 at dome, D. Bedingham, L. Lenz
* cloudy weather => took no images of Sun
* Vignetting images from last week were not symmetric
=> will have to retake those images with diffuse light (outside) and a variety of exposure times to achieve different max/min intensity values,
the ratio of I_max/I_min should be approx the same throughout
Next steps:
* Take correct vignetting images with different exposure times and diffuse light
* Analyse new vignetting images and apply curve fitting to it => V(x) => can receive real intensity with I(x)*V_max/V(x)
* Estimate unscattered intensity f of Sun images
* Fit curve to unscattered intensity => Gaußian fit => should get data back (~Gaußian curve)
* Optimise f

looking into error in blue filter images taken previously
is an error in the programme with the readout, reboots and restarts did not solve this. Updated the verison of IC Capture from 2015 model to 2017, this had some minimal effect
Look at changing the Frames Per Second to a smaller amount (from 30 to 3.75) this did correct for the oscillation problem looking at blue sky
Move to try and take images of sun again with filter
Wait for sun to be away from tree.

Weather Conditions: Clear
Time: 22:40 - 1:50
Targets: Betelgeuse & Pleiades Cluster in RBG filters
Cameras Used: SBIG ST 8XME(camera 1) and SBIG ST-8300M(camera 2)
Both cooled to -20deg
Telescope already synchronised, moved and focused on Betelgeuse. Target too bright for filters. Kept saturating.
Moved to a new target, the star, Bellatrix. Again too bright for filters.
Moved to another new target, HIP26594. 15 images taken for all three filters RBG, exposure time 1.5s.
Then moved to the Pleiades, in narrow view camera (camera 1). We took ten images in each filter with exposure time 10s. And we took ten images in each of the green and blue filters with exposure time 40s.
We switched to camera 2, a wide view that could take an image of the whole cluster. The image is inverted in camera 2. We took 20 images with exposure time 0.4s with no filter.

* set to speed 5, center
* start exposure, bin 4, continuous, center object, speed 3
* adjust focus, unlock primary mirror clockwise 2 revolutions, bracketing process(see how the object is changing), object keeps moving, brightness changes, focus as much as possible, center it again speed 3, synchronize-object,star,named, click for 2 sec
* observede diffraction pattern- something is wrong with the camera, filter plate not moving, adjusting, fixed filter changing
* change exposure time to 0.3s, get star off center, focus on other, dimmer stars, adjust focus once more to see clearly
* discovered diffraction pattern in filter image
* took apart camera with help of Prof Boogert
* once camera filter in working condition, resumed observation
* took exposures of far field stars near Betelgeuse in order to focus the telescope
* shifted focus to plaidees - Atlas and Cleo
* used Astrometry in order to determine our location in the night sky
* once Atlas and Cleo found, took 0.1 interval exposures from 1 to 5 seconds until stars were saturating pixel value
* once pixel values saturated, shifted view to m41 orions nebula
* took one 7 second exposure

15/2/18 Began: 17:30
Started up telescope & opened observatory. Connected to camera with maximdl (disabled camera 2), turned on cooler to -15.
Found Capella @ LST=3:45, h= 22:27, rotated telescope mount. Changed declination to 46 degrees. Located star in viewfinder.
Began continuous 0.1s 4x4 binning image capture of CCD view. Moved telescope (speed 1) opposite to image view due to CCD being upside down, to centre Capella.
Go-to button used, caused telescope to move way off target. Recallibrating as a result. Now LST=4:15, so h = 22:57, relocated Capella. Centered etc.
With LST 4:27, Atlas found at h=0:32. dec 24 deg 6 min.
Used astrometry.net to work out stars from unknown image 1, located area in stellarium
Moved to bright stars (i.e atlas and pleione), checked again with astrometry and stellarium. Synced to Pleione HIP 17851 SAO 76229 on both telescope and stellarium (connected to telescope)
Centred on Pleione. Tested stellarium movement to other stars.
Centred on Atlas, took multiple images at several exposure times, saturating the image individually for both bright stars.
zeroed telescope, closed up dome.
Finished 20:00

Logbook for PH3010 Solar limb darkening mini-project, initial setup meeting
Present: DB, MA, JC, HS
Order of tasks for observation of the sun:
1) DO NOT STARE DIRECTLY AT SUN. DO NOT POINT UNPROTECTED TELESCOPE AT SUN
2) Go outside dome and check that sun will not be obscured by the tree, wind thingy. If it will be, will have to wait before able to take images of sun
3) Check solar filters are not damaged. Fit solar filters to main scope (and if using finder scope, fit solar filter to that). Fit CCTV lens to camera, camera to filters, filters to telescope.
4) Open dome, move opening so that allows shadow of telescope to be seen on dome wall
5) Use the shadow of the top scope (the one secured by two sets of three prongs) to align the telescope with the sun. When the shadows from both sets of prongs overlap, the telescope is (roughly) aligned with the sun
6) If using finder scope, use to target edge of sun.
7) Use IC Capture program to view camera feed (really need to jam the cable into the back of the camera to get the pc to detect it). In device-properties can control gain and exposure settings
8) Use live camera feed to target edge of sun and focus (unlock and use know on back of telescope)
9) Change declination of telescope and monitor live camera feed. Need to find centre-line of sun. This is when any change in declination results in the suns edge moving out of frame (away from centre, only changing declination in one direction will move it out of frame - the other will move it more in frame)
10) On telescope control setup-targets-terrestrial or astronomical
terrestrial will keep telescope at fixed angle, astronomical follows objects through the sky
11) Choose filter to image with. Point telescope as closely as possible to centre of sun and view image histogram. Adjust and exposure until the image is not fully saturating (has a narrow yellow bar - the zero readings - visible) but has as full a range of values as practical.
12) Return telescope to point at edge of sun, in the centre. In IC capture go to the timed capture settings. Choose an appropriate target folder and image capture filenames, set the image type to bmp, turn the 'auto display capture' to off and set an appropriate capture interval and number of captures.
Note: Sun subtends an angle of about 0.5 degrees. Previous years have taken 405 seconds worth of images for this project.
13) capture images. Repeat step 11 onwards for another filter

* Dome entered 10am. Present: MA, JC, HS, supervised by Dr. DB
* Telescope cover removed, solar filters put on
* camera and colour filters were already attached to telescope. setup checked just to be sure
* Telescope setup reviewed+approved by DB
* Dome doors opened, telescope turned on
* Moon was still visible in sky - dome doors moved to allow viewing of it
* Moon used for focus (coarse and fine), took a couple of images of nice craters
* Moon found by (roughly) lining it up with the telescope, then with the finder scope, then with the camera image
* Dome doors moved to allow viewing of sun, telescope slewed to find sun
* telescope shadow aligned on wall behind telescope
* telescope moved to bring the two rows of knobs into alignment (i.e. telescope pointing at sun)
* Using camera feed, approximate equator of sun found at one edge
* Test images taken
* Moon and test sun images stored in focus_images folder
* Colour image sets taken.
* All image sets performed by pointing telescope ahead of suns motion and switching to terrestrial mode - motion of sun across sky then carries sun across the frame of view.
* All image sets taken over 3 minutes 10 seconds. This time determined by timing a test run of the method.
* 1 image per second taken for the length of the image set.
* Used maximum gain for all image sets. Exposure determined by manually slewing across the sun and trialling different exposures. Aim was to get as close to having maximum pixel values in the image, without actually having any maxed out pixels
* Where necessary, solar eclipse glasses were used to directly view sun e.g. to determine if clouds were obstructing the sun, or just the area around it
* Clear Filter 1:
* Gain 799, exposure 1/1000 seconds
* trees obstructing parts of image set - produces obvious errors in dataset
* Clear Filter 2:
* Gain 1023, exposure 1/4000 seconds
* Blue Filter 1
* Gain 1023, exposure 1/154 seconds
* Some obstruction of sun by clouds
* Blue Filter 2
* Gain 1023, exposure 1/154 seconds
* Still some clouds, but far fewer than with Blue Filter 1
* Green Filter 1
* Gain 1023, exposure 1/308 seconds
* Lots of clouds
* Green 2
* Gain 1023, exposure 1/308 seconds
* Even more clouds
* Red 1
* Gain 1023, exposure 1/1241 seconds
* A few false starts (so the file indexing is messed up), but managed to get a good run of images
* Was not able to perform another run with the green filter, due to increasing cloud cover
* Dome doors repositioned above door to roof and closed.
* Solar filter removed and lens cap replaced. Filter stored back in its home.
* Telescope returned to 0h0d
* NOTE: Minor mix-up with imgae file names. All image sets are stored in the appropriate folders / .zips for the colour filter used, but the some image sets use the wrong colour name in the individual image filenames. Recommend handling image sets carefully / renaming appropriately when used.

* Present JC, AD
* Began cooling at 16:45 to -12 deg C (~90%)
* Filter wheel set to Clear, Red, Green, Blue
* Centred on Capella and took GPS-fix. Encountered problem: telescope believed it was -1h RA from Capella however this offset was constant.
* Edit: This seemed to just be an issue with the coordinates read-out on the paddle.
* Centred on M35 and took 1000x0.1s exposures to focus.
* Then took 60s exposure- significant effects of moonlight on image- change target to M36 (RA/DEC: 05 37 13.8/34 09 04)
* Light pollution significantly reduced suggesting moon was indeed the source.
* took 60s and 90s exp in all filters
* moved to (RA/DEC: 05 37 31/34 07 50) and repeated.
* took dark and bias frames before finishing observation at 9:30pm.

PEC Training
Meade LX200GPS Pec Training
- Setup -> Telescope -> RA PEC -> Training
Method
- Connect to Stellarium and MaximDL
- Telescope pointed at Vega synced
- Moved to Epsilon Lyrae (epsilon_lyrae)
- Camera disconnected from MaximDL and connected to PHD Guiding
PHD Guiding keeps the star in the same position at all times allowing the PEC to be trained
Data read with PEC Editor (MyScopeShort) and saved as *.txt file for further analysis
PHD Settings
1st PEC
- RA_PEC_DATA1.TXT
- 0.2s
- Default Advanced Settings with:
- Full Frame
2nd PEC
- RA_PEC_DATA2.TXT
- 0.2s
- Default Advanced Settings but:
- Subframe
Processing Code:
- To be added
Plots for PEC Data:
Test images:
NGC6675 (Spiral Galaxy) - 1 (ngc6675_possible) and 5 min (ngc6675_definite) exposure, 2x2 Binning
M57 (Ring Nebula) - 1 min exposure, 2x2 Binning

Focus and Filters
Average filter wavelength
- Blue: 450mm
- Green: 550mm
- Red: 650mm
ST-8ME Quantum Efficiency:
- Blue: 55%
- 1.82x exposure from clear
- 60s clear -> 109s
- Green: 70%
- 1.43x exposure from clear
- 60s clear -> 86s
- Red: 75%
- 1.33x exposure from clear
- 60s clear -> 80s
Test Images
M57 - Ring Nebula
M56 - Globular Cluster
- 1x60s Luminance image
M27 - Dumbbell Nebula
- 9x60s Luminance images stacked to form a 6x60s image
- 1x109s Blue image
- 1x86s + 2x60s Green images
- 1x86s + 5x60s Red images
During the Dumbbell Nebula imaging the filters were accidentally changed due to the mouse scroll.
- Possible workarounds:
- Use autosave function to take images
- Check before taking a new single image

APIs:
* [[http://seal.web.cern.ch/seal/documents/minuit/mnusersguide.pdf][Seal Minuit]]
* [[http://iminuit.github.io/iminuit/api.html][iMinuit]]
*Performance (measured with Python %timeit() magic function):*
* PyMinuit: best of 3: 13.9 s per loop
* iMinuit: best of 3: 11 s per loop
*Conclusions:*
* iMinuit is easier to install than PyMinuit
* iMinuit is faster than PyMinuit
* iMinuit have more features than minuit (e.g. export to LaTeX and fake functions)
* Both detected and successfully minimized a 2D Gaussian on all the stars with same parameters
* PyMinuit "accidentely" fitted more Hot Pixels than iMinuit
* PyMinuit includes Simplex and Scan methods, which are not available on iMinuit
* PyMinuit is more stable - annoing bug in latest version cause segfault it limits, steps, ... are not set
Keep PyMinuit for now.

| Created: 10 Sep 2013 16:48:33 | Last Revised: 11 Sep 2013 15:49:16 | Public.PedroPaiva | Building Python on cygwin |
pre-requisite: have [[http://www.cygwin.com/][Cygwin]] installed and a GNU compiler.
Cygwin comes with python pre-installed, from there one can install new packages with:
* easy_install packageName
* pip install packageName
To use ==pip== you must install it first using ==easy_install pip==
The ==pip== method is favorable for it allows you to search, uninstall and upgrade packages easily.
==pip== guide:
* ==pip freeze== - display currently installed packages
* ==pip search packageName==
* ==pip install packageName [--upgrade]== - installs or upgrade an already installed package
* ==pip uninstall packageName== - uninstall a package
*Packages installed*
* ipython
* numpy
* scipy
* pyfits
*To be installed:*
* matplotlib
* opengl
* pyside
* pywin32 (don't support cygwin)
* pyminuit ([[http://code.google.com/p/pyminuit/wiki/HowToInstall][detailed guide]])
1 Download the required files: [[http://code.google.com/p/pyminuit/downloads/detail?name=Minuit-1_7_9-patch1.tar.gz][Minuit-1_7_9]] and [[http://pyminuit.googlecode.com/files/pyminuit-1.2.1.tgz][pyminuit-1.2.1]]
1 Extract and change to Minuit directory (under cygwin)
1 Compile Minuit with:
1 bash configure
make
make install
1 Change to pyminuit directory ( ==cd ../pyminuit-1.2.1== )
1 Build and install with: ==python setup.py install --with-minuit=/location/of/Minuit-1_7_9==

Ring Galaxy (NGC1291)
Protostar (IRAS 20324+4057) "The bizarre looking ring galaxy NGC 1291 in Eridanus.
These fairly rare types of galaxy are usually much fainter objects, but this one at "only" 33 million light years away is easily visible in modest size telescopes though the faint outer ring of material is much fainter than this.
Its strange appearance is the likely the result of a collision with another galaxy in the distant past.
20"CDK with FLI-PL6303e camera. LRGB. L: 70mins. RGB: 5/5/10mins" - Damian Peach
IRAS 20324+4057 is a Protostar in the Cygnus OB2 Association, 4,500 light-years (1,380 parsecs) away.
This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
INT: H-alpha
cyan ACS: F606W (V)

After turning telescope on, it successfully received GPS signal and did not started the usual RA movement.
The Camera was connected to Python via MaximDL
Telescope and Focuser connected to Python via the POTH Hub
Coordinates in agrement between Scope, Python and Stellarium
Target was set to be -0.1º RA from current telescope position and Python SlewToTarget was tested.
Telescope moved the right amount and stopped, both telescope and Python alerted when ready.
A second test was made with +0.5º RA. Also successfully.
Still with small (-0.1º RA/DEC and +0.5º RA) movements, Python SlewToCoordinates was tested successfully.
With the tests done, the telescope was moved to Vega via controled movements on Stellarium
Vega was inside the Camera Range, demonstrating that the Park Method works.
Vega was recentered (-0.01 on RA) and the telescope was manually synced.
During this test, movements as small as 0.003º on RA proved to have no effect whatsoever.
The next step was to test the focuser and the camera.
First, while still on continuous mode of the camera, the Python-Focuser connection was tested.
Python can read the position and move the focuser. Units are steps. 1 step = 20µm
Having confirmed that one can move the focuser with Python, Vega was taken out of focus to test if we could focus the star using a small

prin = True

POTHFocuser.Move(step)
while POTHFocuser.IsMoving:
if not prin:

*Focus movements*
* Positive -> In
* Negative -> Out
*Tests*
The data below have a significant experimental error associated with the not fixed measuring equipment.
Also, they can have errors related to a possible angle between the measuring equipment and the in-out axis therefore, the real value would differ by a factor of cos(theta)
*out*
* move(-5000) - 1.86mm
* move(-5000) - 1.80mm
* move(-5000) - 1.86mm
* move(-5000) - 1.81mm
* move(-5000) - 1.88mm
* *mean = (1.842 ± 0.031)mm*
* move(-1000) - 0.31mm
* move(-1000) - 0.40mm
* move(-1000) - 0.44mm
* move(-1000) - 0.27mm
* move(-1000) - 0.45mm
* *mean = (0.378 ± 0.076)mm*
The out movement is coherent and 5000 steps is indeed equivalent to 5x1000 steps
This give 1 step aprox 0.37µm
*in*
* move(5000) - 1.52mm
* move(5000) - 1.55mm
* move(5000) - 1.52mm
* move(5000) - 1.48mm
* move(5000) - 1.57mm
* *mean = (1.528 ± 0.031)mm*
* move(1000) - 0.21mm
* move(1000) - 0.20mm
* move(1000) - 0.15mm
* move(1000) - 0.30mm
* move(1000) - 0.18mm
* *mean = (0.208 ± 0.050)mm*
The in movement is 25 to 50% smaller than the out movement (depending on the movement size) with larger movements closer to the equivalent out.
This give 1 step being between 0.2 and 0.3µm
*Conclusions*
The execution of the above movements led to the following conclusions:
* Focuser always finishes in a 'in-movement' (e.g. asking to move out will make the focuser goes more than needed and come back about 1mm)
* This causes the isMoving check to return before the focus being ready.
* Focuser limit less than aprox 30k steps when going in.
* When close to the limit, focuser will overstep (move(5000) caused the focuser to move 2.76mm)
* Focuser isn't ready when isMoving returns False.
* There's a time gap when a second comand will be accepted but not executed.

[[http://www.newastro.com/book_new/ebook/c2d.pdf][Diffraction aids]]
---------+++ Using a Bahtinov mask to find the focus:
Based on Laurie's idea and [[http://starryvistas.net/articles/focusmask/focusmask.aspx][this article]] a set of 144 images were taken.
3 images for each of the 48 moves made by the focuser. All the movements were 'in' moves of 250 steps.
The images had a 5s exposure time and a master dark (made of 10 dark) was made and reduced from the images.
On each image, a gaussian was fitted to the brightest star (142/144 success) and the amplitude and sigma median were taken for each set of 3 images per focuser position.
The data was then plotted and assumed to be in a quadratic form. The results can be seen on the images below.
For the Sigma X values, the minimum can be found at: 4841 steps
While Sigma Y minimum is at: 5411 steps
And the Amplitude maximum at: 6804 steps
According to [[LogBookAstronomyEntry0015]], the 2000 step (aprox 600µm) difference would be more than double the depth of field for the telescope [[http://starizona.com/acb/ccd/advtheoryfoc.aspx][(287µm on a f/10)]].
A visual analysis of the graphs would suggest a minimum and a maximum for Sigma Y and the Amplitude close to 6000 steps and, visually, the image at step 5750 (image set 23) is the sharpest presenting a nice 'X' diffraction pattern produced by the Bahtinov mask.

* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* Attempted Installation of Python Canopy on personal laptop to begin data analysis but fails to install on Windows 8.0 (Attempting update to 8.1 to see if it rectifies issue) [Installed 32 bit version instead]
* Set temperature value to -07.5 deg C, left for 30 - 40 mins to stabalise.
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* For data analysis will need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.

Using Autosave feature to speed up process, Hence file format has changed to: T-10.0-001-E0001
Must go back to data taken on the 18/10/2013 and rename files for consistancy -> Done.
Proceeded to take another 120 dark frames at -7.5 degrees, as with coolers on 100% sensor temp would not go below -10.6 degrees.
Proceeded to take anothe 120 dark frames at -2.5 degrees.
CCD will then be reset to 0 degrees, and frames will be taken every 30 seconds as it is cooled from 0 to -10 degrees. The exposure time will be 2 seconds. Due to lack of time this will be postponed until next week.

---------+ Project meeting on 24 / 10 /2013
Present: Chris Haynes, Paul Hallam, Ryan Cheale, Dr Boogert, Professor Cowan.
Continued discussion on taking and analysis of dark frames.
Due to the dome not being cold enough during the day, it is difficult to cool the camera down to -15 or -20 celcius. Therefore, the remaining readings will be taken further into winter, when the dome is colder.
Objectives for analysis of dark frames:
* Plot a histogram of the -5°C, 60 second frame and compute the mean, median and standard deviation.
* Plot the column mean and consider the standard deviation for all columns.
* Plot the standard deviation as the square root of the mean and check to see if it's a Poisson Distribution.
Additionally, we should think about the dark current rate (the rate at which an electric current is generated in the chip due to the production of electrons and holes) and how to compensate for it.
We should also consider what the faintest star we could detect would be, looking at the point spread function of our telescope.

---------+++ Activity Log
* Took off cover for telescope & Camera
* Turned on Camera and followed steps detailed [[Students.UnderGraduates.RyanChealeCameraTechnicalAspects][here]]
* Set temperature to -10 deg C, waited 30 - 40 mins for stable temperature
* Used Autosave Sequence located at 'Desktop/Data/20131016_RC/25darks60s.seq'
* Autosave feature allows running of each permutation whilst saving automatically
* Format T-tt.t - NNN - Eeeee.fit where T - temperature, t - temperature value, N - repetition (==20) , E - Exposure, e- Exposure time value (0.1s, 1s, 5s, 10s, 60s, 180s)
* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* turned off the coolers on the camera to allow it to reutn to room temperature.
* Proceeded to take data in 30s intervals for 30mins whilst turning the coolers back on and allowing the temperature to reduce to -10 deg C to see what effects allowing the temperature to stabalise has
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* For data analysis still need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.
Python
* Began the use of the canopy environment to begin data analysis in Python.
* Running into multiple problems with the canopy environment with plotting graphs
* Have made plots for the mean, standard deviation, max and min values of the data set T-05.0-NNN-E0600
* Struggling to create histogram plots, either the kernal or the environment tends to crash when trying to create a histogram of a single fit file
* Next steps:
* Produce median plots
* Refine code so only needs slight input alteration for other data sets
* Produce histograms and then further plots based off of the histograms
* begin analysis on cool down data.

A study into the variation of background pixel count with temperature.
Initial CCD temperature was recorded to be 18 degrees. Coolers were turned on and CCD cooled to 0 degrees over the course of an hour, to ensure the entirety of the CCD began at zero degrees for the following study.
Coolers were then set to cool the CCD to -10 degrees, and one second exposures were to be taken every 30 seconds for one hour over this cool down period.
The data shall be saved in the following format: Cooler_Study-001E001
Also this shall also provide 29s exposures between the 1s exposures, which shall appear like this: Cooler_Study-001E029. This data will not be analysed.
When this collection of data has been finished, CCD was at a constant -10 degrees. The CCD coolers were switched off, and the CCD warmed back up to room temperature. Using the same method, one second exposures was taken every 30 seconds for one hour over this period.
The data shall be saved in the following format: Cooler_Study_2-001E001
Again this will also produce data that will not be analysed, in the form of: Cooler_Study_2-001E029
Room temperature in this case is 25.6 degrees.

---------+++ Telescope Set Up
* Target Delta Cephei selected using Stellarium and AAVSO catalogs
* Open shutters (ropes, pull apart, tie off ropes, motor control
* Turn power on
* Press power switch on telescope
* Removelens caps
* Point towards Vega
* Line up with finer scope
* Take continuous frames 0.1s
* Center Vega in frame
* Synchronise Vega with Maxim DL and Stellarium
---------+++ Target Information
* Pulsating Variable star, magnitude variation 3.5 - 4.4, Δm = 0.9
* Period 5.4 days
* Next maximum, 07/12/2013, 9:32
* RA: 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From simulated light curve - expected Δm(max) = 0.26, expected Δm(min) = 0.01
* From light curve of Delta Cephei, and time of next maximum, we believe the magnitude should be decreasing
* Companion star HIP 110988 used as a reference star
---------+++ Initial Observation of Delta Cephei
* Centered on Delta Cephei - did not use Stellarium as could move telescope through the pole
* Frames were taken using different filters, initial exposure times:
* No filters - 1s
* Blue filter - 10s
* Green filter - 3s
* Red filter - 3s
* Took sample frames using this-set up, max pixel count was found using Python
* Re-evaluate exposure time to ensure max pixel count was in the range 55000 - 60000
* Re-evaluated exposure times:
* Focus filter - 1.1s
* No filter - 1s
* Blue filter - 10s
* Green filter - 5.1s
* Red filter - 3.3s
* Decided to take 5 repeats for each of these, and 10 repeats for Dark and Bias frames
* Autosave feature was used to take a sample set of data
* Residual image of Star found on Dark frames - low pixel count
* Implemented a 'Trash' frame before the Dark frame to attempt to remove this -> some residual image still remained
---------+++ Observation of Delta Cephei
* Autosave feature took approximately 10 - 15 minutes to run
* Approximately three runs were taken per hour
* Delta Cephei was observed for 5 - 6 hours
---------+++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope
* Turn off camera
* Turn off telescope
* Put cover back on camera
* Close dome shutters
* Turn off PC monitors
* Turn off lights and leave dome

20140213 LN
Reasonably clear and forecast to be good. Worth a try to get some practice in.
* CCD at -15oC
* Aligned to capella - very high in sky.
* Went down from 46 to 37 DE to theta_aur as capella saturates the camera.
* Take subframes to practice focussing. Recorded 400 frames of theat_aur for analysis later. SNR is good as super bright. Peak around 30000 ADU. Jumps around A LOT so will have to align by centroid. Then can have a look at PSF.
* Exposure 0.1s
* 300 exposures recorded in 10m12s
* 400 exposures recorded in 13m37s *Sat bhatinov mask carefully on front of scope. Recorded 50 images with same setup as before. Not so clear.
* Exposure 0.5s
* Not so clear. Pattern seems very small indeed on CCD compared to internet images. Collimation is definitely poor and its windy so don't expect it to be great. Anyway, reasonably good in focus.
* Having a look at the Pleiades. Too extended to see anything nice and certainly with the seeing. The stars are very bright and the nebulosity not so, so quite hard to observe under these conditions.
* Imaged Andromeda ok. 30s exposures.

Using the spectrometer to find the brightest spectral line in mercury and Find the best micrometer reading for the angle of the camera.
Camera was ST-7E, Setup SBIG Universal.
Temperature for all the images was -6.5 deg C.
*Focus*
Exposure time: 0.1s; Grating distance 1.814mm; Camera angle micrometer reading 2.495 (heavily sloped)
Used continuous range to find a reasonable staring point.
Used range of 18mm to 20.5 mm in steps of 0.5
Reduced range to 19mm to 20.5mm in steps of 0.10
Reduced range further to 19.50mm to 19.80mm in steps of 0.05
*Camera Angle*
Exposure time: 0.1s; Grating distance 1.814mm; Focus distance was 19.60mm for this
Used continuous range to find staring point.
Used range of 2.50mm to 5.50mm in increments of 0.5mm to start.
Reduced range to 4.00mm to 5.00mm in steps of 0.10mm
Reduced range further to 4.45mm to 4.65mm in steps of 0.05mm
Found the best angle to be _4.60mm_
*Brightest Peak Data*
Looking through the spectrum the brightest peak, found at 4.00mm in grating micrometer.
This was saturated so the lamp was moved back by 5cm which was still saturated, then we moved it back by another 5cm which put the lamp back from the optical fibre by 25cm. This reduced saturation where refocus was done. Seemed to saturate at 50,000 confirming it was brightest peak.
Used this to check the focus and recalculate.
used a range from 19.50mm to 20.50mm in steps of 0.10mm
Found best focus distance on micrometer to be _20.10mm_

27th Oct 2014 Msc Observation.
*Begun:* 18:30
*Finished:* 22:30
Conditions: Mostly clear, a little muggy. No cloud coverage.
Begun observation session with a run down of the procedure to prepare the dome.
*Dome Procedure:*
-
Enter dome
- Close the hatch to prevent heat rising and entering the dome. The floors beneath are heated which causes a ‘chimney’ like effect if the hatch is left open as the hot air from below will rise up through it. Ideally the scope and dome should remain cool so noise due to thermal fluctuations is kept to a minimum.
- In the Maxim DL suiteconnect to the telescope. This allows control of the camera for example you can set exposure times and capture images from the program.
- Enable the CCD cooler in Maxim. This should be done ~1 hour before taking exposures. If you take observations too soon after enabling the cooler you get a ring like effect on your observations around the outer area of the frame. The ring progresses further to the sides of the frame as the CCD cools until it eventually disappears.The set-point of the cooler is set to -10 degrees celcius and the CCD itself fluctuated around this point slightly once the cooler had taken full effect.
- Untie the ropes that control the shutter of the dome. Pull on ropes to open the shutter of dome, if the shutters do not open with ease, there is a long stick with a metal prod at one end which can be used to manually push the shutters open from near the top of the dome.
- Once shutter is open, tie the ropes off again to make sure that they are kept out the way of the moving parts of the done which can rotate bothe counter and clock-wise
- Using the door on side of dome, go outside and do some preliminary naked eye observations to find an interesting object to observe (this is important for aligning the telescope as detailed later on). This allows you to plan roughly where the telescope and open shutter should be pointing to allow unrestricted viewing.
- Using the dome control unit, align the dome opening with what you want to observe.
- When finished observing, realign both the dome and telescope to their origional position. Close the dome shutters and tie up the ropes.
To begin making observations you need to align the telescope to a bright object in the sky and then enable tracking. Tracking corrects the position of the telescope relative to the sedereal motion of the stars. This is necessary because the field of view of the telescope is so narrow if it was left stationary, the object you are observing will move out of frame. To align the telescope, the first step is to identify a bright object visible to the naked eye in the nights sky. You can acess the roof from the dome via. the door on the side. Once on the roof you are able to evaluate potential targets. We identified the star Vega (25ly away, 2.1M0, alpha lyrae - the brightest star in the lyra constellation and 5th brighest in the night's sky). The star charts provided in the program stellarium coupled with manual positional measurements allow you to identify the star you are looking at with the naked eye.
Once a object in the sky has been chosen, the next step is to align the telescope to enable the activation of tracking.
- *Telescope Alignment:*
-
Use a high speed on the control paddle (speed button -> 9 is fastest, 1 is slowest on number pad) to crudely align the scope with what you want to observe using the arrow buttons. This can be done roughly by eye by lining up the two bolts on the side of the telescope with what you are looking for.
- Then use the viewfinder which has a set of crosshairs to align the scope more accurately with the object in the sky. A medium speed setting on the paddle can be used to move the scope with a greater deal of precision.
- Once the crosshairs are centred on the object you wish to view, take an exposure in the maxim DL suite. Once the image has been taken and downloaded you can adjust the scope to get the object centred in the frame. If you set maxim DL to take continuous ~1s exposures you can get a better sense of the best way to align scope and object.
- Once the scope is aligned, enable GPS lock. This continuously corrects the scope to account for the rotation of the earth. The field of view of the scope is very narrow causing the object you are observing to move through the frame if the scope remains stationary.
- Once tracking is enabled, the scope should keep the object you are trying to view in frame automatically.
- Using the control paddle, tell the telescope which star/object it is currently aligned to
- With the telescope connected to stellarium which now allows you to control the scope through the program itself. Using the star charts, you can align the scope to stars/objects shown in stelarrium. (Wait for the ‘beep’ if you move the scope in the program. The scope moves quickly at first but then makes finer corrections to ensure the scope is aligned well. The 'beep' occurs once the telescope is properly aligned, it can take some time ~20-30 secs).
- While repositioning the telescope it is important to be aware of it's orientation with respect to it's base. The telescope is capable of flipping over on itself which can cause the CCD attatchment to collide with the stand. In a situation where this may happen, power down the telescope via the power controls located on its stand immediately.
With the telescope aligned you can control where it is looking via. the stellarium program. Multiple exposures of Vega were taken at different exposure lengths using the Maxim DL program.
Using stellarium, the telescope was then trained on the open cluster M-39 in the constellation cyganus (800ly away from earth). Again took multiple exposures. The cluster is composed of a number of stars. Using the star chart in stellarrium the star patterns were compared to that shown in the exposure allowing for individual identification of the stars the cluster is made up of.
You have the ability to manually focus the telescope. If it is out of focus the exposures of stars can present as donuts (dark centres with bright outer ring) or they seem flat and blurred at it's edges. The procedue to manually focus the telescope is first to 'unlock' the mechanism. There are two dials, the shorter one can be rotated to unlock the device allowing the second longer dial to be turned focusing the telescope.
Last target of the night was the andromeda galaxy known as M-31 (as it is a messier object) and is 2.5x106 ly away from earth and the closest spiral galaxy to the milky way group. This galaxy has a mass ~ 1.5x10^12 M0. 10 exposures were taken one after the other with the intention of eventually using them to form 1 image with considerably less noise.
An interesting point to note is that movement of the atmosphere above the telescope can cause exposures to shift in and out of focus. This was made evident as during continuous exposures of M-39, the stars were alternating between being in focus and out of focus.
The exposures taken during the night of observation are attached to this post.

*Observations of the Spectrum of Betelgeuse*
Started looking at Capella. Using a small sheet of tracing paper to allign the star in the optic fibre coupling. With Capella at a high Altitude we switched to Betelgeuse as a target to make allignment easier.
Viewed Capella at
5hrs 20' 30'' RA
45deg 8' 2'' DEC
with the micrometer at Grating-4mm, Angle-3.25mm, Focus 20.2mm.
changed the RA 5'' either side to align it centrally while observing the intensity recieved.
*Betelgeuse*
Next look at Betelgeuse,
5hrs 58' 32' RA
6deg 25' 30'' DEC
Took a 30s exposure at 4mm to look at the spectrum as best as possible. Then took 60s exposures of Betelgeuse between 0mm and 10mm in steps of 0.5mm.
After Betelgeuse we briefly moved to the Orion nebula however it was too dim to observe.
*Pollux*
7hrs 46' 14'' RA
27deg 59' 18'' DEC
Again took 60s exposures from 0mm on the grating position micrometer too 10mm in steps of 0.5mm.
Laurie left at 23:00
*Castor*
7hrs 35' 22'' RA

Please edit and put your text etc. here
Start Time: 19:00
Conditions: Slightly cloudy at start, quickly became clear around 8pm and remained clear.
Observations:
*Castor (Alpha Gem)*
Aligned to Castor, RA: 7h 34m 35.87s, Dec: 31dg 53' 17.82" Apparent Mag: 1.93
Ring visible due to cooling of CCD chip taking place.
*Near Castor*
Observed multiple stars near Castor with low magnitude (10 - 15)
No images taken.
Ring still visible.
*NGC2388*
Centred on galaxy NGC2388, Apparent Mag: 14.
NGC2388 was chosen as a target as it is known to currently contain a Supernaova of Apparent Magnitude 15. See http://www.rochesterastronomy.org/snimages/snactive.html
Supernovae: PSN J07285387+3349106, RA: 07:28:53.87, Dec: +33:49:10.6, z = 0.013790
One frame was taken at 120s exposure. Stars were cross checked with Stellarium and were found to be low magnitude (10-16). Two other galaxies were also clearly visible, NGC2385 and NGC2389. The cooling ring was still visible at the edges of the frame. This location was chosen for the target of this observation due to the number of low magnitude stars, and the presence of three galaxies.
Uploaded a frame to astrometry.net
Experimented with 180s exposure, decided to use 120s.
Stacked frames using MaximDL built in image stacker to invstigate noise reduction.
Images taken:
Data was taken in bursts of 9 images, 3 Light Frames with 120s exposure, 3 Dark Frames at 120s exposure and 3 Bias frames.
Dome was realigned every 2 bursts to ensure unobstructed view of the sky.

---------+ 2015 05 20 LN DSLR Observation
* Trying out DSLR on back of scope
* Benefit - easy live video to investigate focussing, wide field of view
---------++ 20:30 start
* Dismounted SBIG camera (in case)
* Canon DSLR bayonet adapter + BADER 2" - T/2 Nosepiece on back of micro-focuser
* Observed Moon, Venus & Jupiter during twilight ~ 21:40
* Aligned & synchronised to artturus star to the south as visible to the naked eye
* image of M3 globular cluster ~ magnitude 6 - can make out ok in photos but still blue sky background as still slightly light
* 2155
* Trial of Deep sky object - still lightish but will keep iterating over objects
* Bodes Nebula mag 6.9
* Of note is that the DSLR is slim enough for a polar flip of the mount. Haven't, but can.
* Whirlpool Galaxy
* Getting better images but can only really see core of galaxy - still to much sky glow
From images of a single bright star or say of Jupiter and it's moons, you can see what appears to be both coma and chromatic aberration. The edges of non-point like objects have an orange tinge on one side and a blueish tinge on the other. Jupiter is relatively low just now so there is a strong affect from the atmosphere / imaging but still Jupiter had an asymmetric tinge. The moons were also quite distorted. Although the 'live view' gives you some indication, it simulates the exposure settings and can distort the image a little. Best to take images directly and zoom in to compare. Not too different from live view though.
* Telescope likely needs collimation, but the trouble is finding a good enough night for to be able to observe any improvement.
Sky much darker now. While no clouds around, there is a bit of haze - can't see huge multitude of stars.
* Starting at 3845 images of great cluster in hercules.
Finish at 22:20

---------++ *Before taking data*
* Time of turn on: 18.20.
* Cooler set to -7 degrees.
* Temp at -6.9 degrees at 18.30.
* Center the telescope on Vega.
* Aling the telescope to Vega. (~Mode on the controller)
* Speed 5 and later 3 on controller while focusing on Vega.
* Microfocuser used to fine focus.
* Speed 3 to place Vega in the center of the image.
---------+++ Alpha Persei Cluster (Cr 39, Mel 20)
* We chose our cluster as the Alpha Persei cluster.
* To focus on the cluster we chose a nearby bright star Mirphak.
* We used it to correct our ofocusing and we synched Stellarium wityh the telescope.
* We choice a patch of the cluster (HIP16001) and took 10 vimages of 10 second exposures. ( x binning set to 1, x anmd y originally inverted, this was reversed)
* 5 bias frames and dark frames of 5 1min exposure.
* Took 3 40 s red.
* Took 3 40-s gtreen.
* Took 3 90 s blue.
*
* Move to a different patch (around RA:3h29min29s, DEC:49deg44'16")
* Ian joined us at 20:00
* 3 images of 60s visual.
* 3 images of 120s red.
* 3 images of 120s green.
* Finished taking data at 8.30 pm.
---------+++ Dark and bias frames
* Started taking dark frames. 5 images of 120s.
* Take 10 bias aswell.
Observation finished at 8.56pm.

The aim of the session was to modify the parameters of the camera. Using only OpenCv it was impossible to set the camera's parameters with known units.
py-ic-imaging-control was downloaded from: https://github.com/morefigs/py-ic-imaging-control
py-ic-imaging-control is a python wrapper for the IC imaging control software development kit from the imaging source (TIS). It provides control to TIS cameras, and can serve as an alternative to using OpenCv to access the cameras parameters.

The DMK camera was fixed to a tripod and pointed at the moon.
Run1: Gain set to 180 and images were recorded of the moon at a frame rate of 7.5 frames per second. The algorithm left the exposure setting on 1 as the image was not over or under exposed on this setting.
Run2: Gain was increased to 1023. The images were over exposed and the algorithm accounted for this by changing the exposure setting in increments of 1. It was noted that this was very slow to respond to large and sudden changes in conditions.
Run3: The code was modified such that the amount the algorithm changed the exposure setting depended on the number of pixels that were saturated. This massively decreased the time the algorithm took to find the correct exposure setting. See screen shot.
Images were also taken of Orion's Nebula, see image file names for parameter settings.

Az/Alt: 318deg 44'20''/38deg34'50''
Took testing pictures: Cooling_1 and cooling_2, can be seen a ring surrounded by the ice. Secong image shows larger ring, meaning hte camera is cooling down
Cooling_3 image is clear and even
Checked the wether with met office, clouds are exopected to clear for the rest of the night
Finding the star by eye, alighning the tescope, using stllarium found it was Procyon
As it wasn't clear that the star is Procyon, checked with Rigel
Took images of the delta cep with no filter and with filters: red, green, blue and spectroscope. Aimed for 50 000 pixel value - the closest to the maximum possible p.v.
Exposure time was increased as different filters were applied, because different filters obsurb more light.
Cloudy weather led to taking many pictures for blue filter with longer exp time, 16 sec.

Please edit and put your text etc. here
---------+ Finding focus of optical fibre
* The focus of the optical fibre was found by taking a relative distance between the lens and the position of the optical fibre, and measuring the amplitude of a spectral line from the laser found at 3.5mm.
* taken at 1mm intervals between 230m and 270mm.
* Fit with hyperbolae as approximation
* distance measured with ruler so very approximate i.e ±1mm
* Best focus was found at 250mm±2mm
* Iris was almost closed as the laser would saturate camera at shortest exposure.
* also took more data as SBIG ST-7E was cooling.
* Just need extra part to connect firewire camera, so that the alignment can be competed.

Please edit and put your text etc. here
---------+ Focussing Beam Splitter
* To find best focus should be able to focus onto a single fibre, once one illuminated, in focus. will have to use extension rings for optical fibre.
* CCD camera can then be adjusted until in focus.
* Focus by shifting backwards and forwards on rails.
* Find focus of camera with max intensity and minimum width of laser.
* Use diffuser or neutral density filter, will need neutral density filter.
* Make two plots of intensity on camera and fiber and adjust until peaks overlap.
* Such that there are two plots which look similar to:
---------+ Aligning Beam Splitter
* Align by moving the mirror horizontally and vertically until maximum intensity
* possibly get 3 more irises, to control aperture at camera, fibre and entry, to make sure always have good alignment.
* As now in focus, can scan around fibres and find the relative positions compared to the end where they are arranged into line.
* This could help with finding best position of ray on camera
* Look up mirror and see how much change in angle before lost fibre, one full turn until laser out of view.
* try to get two irises as far away from each other for best alignment.
* once part for CCD arrives, move around and find relative positions on camera to positions on optical fibre.
---------+ Relating to telescope
* Have to use larger beam size so that f# is the same as the telescope, f# = 10,
* currently 3 dioptre lens, so 1/3 m focal length, this means need a beam diameter of 33.3 mm or a longer focal length.
* as , where f is the focal length, d is the diameter of beam or aperture and f# is the f number.
* consider which camera to be used.
* beam splitter reflects 30% and transmits 70% so check this.
---------+ testing intensity
* tested the intensity at reflection and transmission, with diffuser and tissue in front of laser, tissue made intensity vary substantially so averaged over five frames, the reflection intensity was found to be 3% of the transmission intensity, however there could be problems with focus and alignment at the refection, need better analysis of this.

---------+ Aligning Camera and optical fiber
* Spectrum images,
* Exposure: 0.1s
* Temp: 10 deg
* used subframes around spectral to speed up
* FireWire camera * Exposure: 1/500 s
* The FireWire camera was attached to the beam splitter and connected to IC capture
* Optical fiber was attached using a spacer to approximate the same focal length as the FireWire CCD
* Initially an approximate focus was found on the FireWire camera.
* Then the angle of the mirror was adjusted vertically such that the laser beam was scanned vertically.
* images of the position on the CCD and the spectrum were taken at a range of positions.
* The amplitude of the spectral line was then recorded with position on the CCD.
* This gave a plot shown below for the maximum intensity. i.e centre of fiber
*
* This was then repeated for a scan horizontally, which gave the plot below.
* The best positions were found to be at [190,218] pixels, i.e 190 pixels across and 218 pixels down
* The the focus of the image was to be found.
* The box which the beam splitter and camera is attached to was placed on the rails and scanned backwards and forwards using a ruler for approximate focal length.
* Images were recorded for both the camera and optical fiber, and the amplitudes were plotted against focal length.

Please edit and put your text etc. here
---------+ Alignment of Camera and Optical Fiber
* SBIG camera,
* Temp: 10deg
* Exposure: 0.1s
* subframe around fibers
* FireWire Camera,
* Exposure: 1/500 s
* Took focus measurements first by moving beam splitter to find best focus.
* Best focus was found by subtraction background of spectral line image and summing pixels
* Best focus for image was found by finding max pixel value
*
* The optical fiber focussed ~6mm from the FireWire camera
* Optical fiber was adjusted such that it is as far out as possible using the smallest spacer, and the camera was adjusted so that it was as close to the beam splitter as possible.
* This was to close the 6mm gap found earlier
* The fiber and camera were then realigned as the FireWire camera will have been rotated slightly and moved out of alignment.
* Both horizontal and vertical alignment were used and the best positions were found at maximum intensity the same as for the focus.
*
---------+ Attachment of guidescope
* Two mounts for the dovetail plates attached on the top of telescope, plate then attached.
* The two dovetail plate mounts for the bottom of the telescope have to have small section removed due to bolts on the telescope which were in the way.
* Bottom dovetail plate then attached.
* guidescope rings and guidescope attached to the top plate
* counterweight attached to bottom.
* The telescope was then approximately balanced by adjusting the counterweights position on the plate and by unscrewing the counterweights so they were further from the OTA.

Please edit and put your text etc. here
---------+ Alignment of fiber horizontally and vertically
* SBIG camera for spectrometer:
* Exposure: 0.1s
* Temp: 10 deg
* Subframes
* FireWire Camera:
* records video at 30fps
* Exposure: 1/500 s
* Approximate focus was first found. set at 255 mm
* The mirror was adjusted horizontally such that the laser moved horizontally in the camera frame.
* Images were then taken of both the spectral line of the laser and the image on the FireWire camera as it was scanned, 40 images were taken.
* The maximum intensity of the beam and its position were recorded on the FireWire camera and the summed intensity was recorded for the spectrum with removal of backgorund.
* The intensity on the spectral line was then plotted against the position on the FireWire camera, this gave a plot shown below.
* The peak position on the above plot is then used to set the position of the beam on the camera, which is approximately at a position of 200 pixels.
* Once the position has been set the process was repeated scanning this time vertically, this gave a plot as shown below.
* The best position for the beam to be on the camera for max intensity at this stage is then at pixel values [200,216].
---------+ Focussing the beam
* Once the beam has been set to the best position as found earlier the camera and optical fiber were adjusted between distances of 220mm-290mm in 2mm intervals to find the best focus.
* Here the same measurements as before were made. The intensity of the spectral line and the maximum intensity of the FireWire camera are plotted against focal distance.
* The plot of both the camera and optical fiber is shown below.
* With this image the approximate best focus was set at 250mm
---------+ Repeat of alignment
* The alignment process was then repeated as before, this gave the below plots.
* These gave maxima at a pixel position of [201,217], The image below shows the position of the laser of the camera at this point:
---------+ Horizontal Scans at different Focal lengths
* For 6 different focal lengths, 240,244,248,252,256,260, a horizontal scan of the laser was recored on the camera and the spectrometer. This range was chosen as in the above focus plots, this is where the intensity flattens.
* For each of these the position of the laser of the FireWire camera was plotted against the total intensity of the fibers.
* The aim was that the focal length which gives the smallest width of a spectral line is the correct focus.
* The plot below shows the intensity plot for each of the focal lengths, and the widths of the line.
* This shows the widths does not change much in that range, this could be due to the fact that the focus is smaller than the size of the optical fiber, therefore, the integrated amplitude will remain the same in this range.
* Therefore, by selecting a single fiber to integrate the intensity over, it should be possible to find focus.
* The below plot shows the same results for a single fiber
* This shows that the width of the line drops in the range of 252-256 mm .
* by fitting a Gaussian function to both the image on the firewire camera and the plots above, the widths could be plotted against the focal length for both.
* Each of these were then fit with a hyperbola function,
* This gave parameters of,
| parameter | FireWire | Fiber |
| mean | 254.8±1.2 | 255.2±1.1 |
| a | 4.28±0.92 | 6.12±1.25 |

Saqib Hussain + Jervis Ong Arrived at 16:24, weather clear
* AA arrived 17:30
* Took example flats with both cameras
* Setup telescope, synched on Vega
* focused the telescope on a star
* took a few dark frames to distinguish dust on the telescope
* Primary observation target identified : rho Cyg- 73 Cyg - HIG 106481, right ascension = 21h 33m 58.85298s, declination = 45° 35′ 29.1 "
* Checked the camera cooler temperatures: -5.2 for ST8 and -15.0 for ST8300
* Took exposures with exposure time 0.1s for ST8300 and 0.5s for ST8
* For ST8300, file names begin with odd alphabets (a,c and so on) whereas for ST8 file names begin with even alphabets
* The data is compiled as below:
| Telescope | Exposure time/s | Time frame/minutes | No.of Images | File starts with |
| ST8300 | 0.1 | 12 | 66 | a |
| ST8 | 0.5 | 12 | 45 | b |
| ST8300 | 0.1 | 16 | 100 | c |
| ST8 | 0.5 | 11 | 45 | d |
| ST8300 | 0.1 | 9 | 45 | e |
| ST8 | 0.5 | | 45 | f |
* Moved on to collate data for atmospheric extinction
* For ST8, we tried to take images with different filters (luminescence, red, green, blue) for an exposure time of 0.4s
* However, due to technical problems we were unable to take images with colour filters
* We continued taking unfiltered images every 10 minutes (as the star moved from the azimuth to the horizon), saving them as files beginning with L
* Exposure time is 0.5s for every image
* Cooling power was within the range of 40 and 49%
* Data are as follows:
| Time | File Name |
| 2158 | L1 |
| 2208 | L2 |
| 2218 | L3 |
| 2228 | L4 |
| 2238 | L5 |
| 2248 | L6 |
| 2258 | L7 |
| 2308 | L8 |
| 2318 | L9 |
| 2328 | L10 |
| 2338 | L11 |
* took a photo of Andromeda
* Turned the coolers off, disconnected the cameras. Double checked everything was disconnected.
* Exported data into USB stick.

set up procedure
* check for damages on solar filters
* solar fillters on finders scope and main scope
* mount camrea
* use a SCT connector
* screw onto fliter and telescop
* RGB filter
* clip onto tube
* C-mount to 1.25 inch tube
* screw onto camera
* camera
* mount camera unto telescope by unscrewing the big ccd camera
* fire wire cable connected to the camera(clips in)
* with them, covered you can open the dome doors
* switch on telescope
things differe form a normal observation:
* use different type of camera( imaging source dmk 21af04.as)
* use a different piece of software
* stop the tracking
IC capture
* open IC capture
* click camear being used
* device properties click off auto gain and exposure
* check if histogram isnt saturated
* adjust exposure so it is not saturated
* saving sequnece of image
* capture -> squence settings
* file name and target, pick a directory(desktop/data/YYYYMMDD) -> index at 1
* file type BMP
* Automated sequence -> interval at 1 sec -> end sequence after 400 Frames
* capture -> sequence timer -> start timer
how to turn off tracking
* set up -> enter
* targets -> enter
* trestral or astonamical ->enter
we are going to be using 2016-11-02 data

time: 17:22 arrived in dome. ENK JT AS AC AA
remove rain cover from telescope
open doors of dome (ropes(tie up), bolts)
go onto roof and observe sky
select Capella(HIP 24608) on Stellarium
RA/Dec 5h17m57.85s / 46deg 00' 40.4''
h(capella) = LST(egham) - \alpha = 1h41m52.8s(egham) - 5h17m57.85s(capella) =-3h36m5.05s
rotate dome to correct direction
callibrate telescope - move telescope manually to point at Capella, it can then know its position on the night sky and be moved using the stellarium programme
first take caps off telescope, turn telescope on(make sure everything is plugged in and switched on,checking all leads and sockets)
telescope automatically moves towards the west)
centre capella in finder scope(scope speed 5)
Synchronise coordinates on Capella ( object -> star -> named -> Capella -> Enter (2 seconds) -> Enter to sync)
move telescope away from capella
use the go-to key to get back to capella
Move to almaaz(HIP 23416) using the hipparcus catalogue method outlined in the script
Use Hip method again to move to Betelgeuse (HIP 27989), and bellatrix (HIP 25336)
open MaxIm DL Pro 5
exposure 1 sec start poor out of focus picture
change exposure to 0.1 sec, X bin 4 continuously taking images
use knobs on scope to unlock mirror and change the focal length, simultaneously slowly moving scope to get the star in the centre of the field of view of the CCD
get star in and out of focus and take picture
calibrate telescope to set on aldebaran
use focus (4 on pad) to get good focus with microfocuser that changes the camera not the mirror
take images in different exposuresmove to fainter section of sky, star cluster near aldebaran cluster 2 shows fringe from coolingtake 10 images to find saturation around 65000 for this CCD
move to 02 Tau and found bleeding and saturation at 10s, took multiple images at different exp times (1x1 binning)
found that simple auto dark callibration was on contiunued with this then took one without this

Weather - cloudy fairly poor visibility
* set up telescope, open dome, take off caps etc
* take picture of blank space, set up guide camera also
* twilight point scope at blank space look at cooling and non cooling effects
* target is betelgeuse, use to focus and synchronise camera
* move scope to pleiades, new target in order to take pictures of cluster, image with multiple stars
* centre on atlas and pleione
* look at error in plate scale as a function of flux ALL FRAMES!!!!!!!!!!!!!!!
* f[0].header this shows all the info about the image and the telescope
* shape(d) Out[40]: (1020, 1530) dx1 = d[0:500,:].sum(0) dx2 = d[501:,:].sum(0) plot(dx1) this will set a range on the x/y axis

time 10:30am arrived in dome. A Cozens, L Lenz D Bedingham S Boogert
poor weather conitions so no solar data could be recorded
used SLR camera to take images of boiler house in order to understand how the manual settings of the camera affect images
took 30 images with different exposure times and varying the ISO number, as ISO increases smaller exposure times are required so not to saturate the image.
The images are located
C:\users\astrodome\desktop\3_data\20171018_Solar
with two files showing the dark frame images taken to show the noise of the camera with the cap on the lens and light brick images taken at different exposure times with different ISO

10:30 dome. Bedingham, Cozens, Lenz
* good weather => took a few images with Canon SLR camera
* The following settings received best results: ISO=100, exposure time=1/4s to 1/8s, max. f-number
* Used rawkit Python package to transform .cr2 files into .tiff
* Applied Hough transformation to find circles in image
* Measured brick width L with ruler and received distance D from dome to boiler house brick via Google Maps
=> L = 22cm, D=104m
* From this calculated angle to be θ = 2*arctan((L/2)/D) = 0.117° = 0.22x(angular separation of sun(0.5°))
* Next steps: - take image of smooth white background to measure the vignetting effect of camera
- adjust parameters of Hough transformation to find correct circle

use DSLR to take white images to look at the natural vignetting effects of the camera, took many exposure times so to get an unsaturated image. Need to process these to get a pixel vs intensity curve to show that the fractional ratio of intensity does not depend on exposure. Also look at different colour channels and create a plot to show all 3
Then set up the telescope so as to record data, fit with sun filters and imaging source camera. Using ICcapture software.
Use shadow of the telescope to align, and adjust further with finder scope.
set telescope to the west of the sun to see it passing through the window, takes around 1min to fully pass no data recorded
Use DSLR to take images of the sun, lowering the exposure times to find an unsaturated image. Use circle finder code to analyse the intensity array across a diameter of the sun.
Attached Text files show the image numbers on the DSLR for varying exposure times ISO=100 for targets of the sun then a white light source evenly lit for investigating the vignetting effect.

10:30 at dome, D. Bedingham, L. Lenz
* cloudy weather => took no images of Sun
* Vignetting images from last week were not symmetric
=> will have to retake those images with diffuse light (outside) and a variety of exposure times to achieve different max/min intensity values,
the ratio of I_max/I_min should be approx the same throughout
Next steps:
* Take correct vignetting images with different exposure times and diffuse light
* Analyse new vignetting images and apply curve fitting to it => V(x) => can receive real intensity with I(x)*V_max/V(x)
* Estimate unscattered intensity f of Sun images
* Fit curve to unscattered intensity => Gaußian fit => should get data back (~Gaußian curve)
* Optimise f

looking into error in blue filter images taken previously
is an error in the programme with the readout, reboots and restarts did not solve this. Updated the verison of IC Capture from 2015 model to 2017, this had some minimal effect
Look at changing the Frames Per Second to a smaller amount (from 30 to 3.75) this did correct for the oscillation problem looking at blue sky
Move to try and take images of sun again with filter
Wait for sun to be away from tree.

Weather Conditions: Clear
Time: 22:40 - 1:50
Targets: Betelgeuse & Pleiades Cluster in RBG filters
Cameras Used: SBIG ST 8XME(camera 1) and SBIG ST-8300M(camera 2)
Both cooled to -20deg
Telescope already synchronised, moved and focused on Betelgeuse. Target too bright for filters. Kept saturating.
Moved to a new target, the star, Bellatrix. Again too bright for filters.
Moved to another new target, HIP26594. 15 images taken for all three filters RBG, exposure time 1.5s.
Then moved to the Pleiades, in narrow view camera (camera 1). We took ten images in each filter with exposure time 10s. And we took ten images in each of the green and blue filters with exposure time 40s.
We switched to camera 2, a wide view that could take an image of the whole cluster. The image is inverted in camera 2. We took 20 images with exposure time 0.4s with no filter.

* set to speed 5, center
* start exposure, bin 4, continuous, center object, speed 3
* adjust focus, unlock primary mirror clockwise 2 revolutions, bracketing process(see how the object is changing), object keeps moving, brightness changes, focus as much as possible, center it again speed 3, synchronize-object,star,named, click for 2 sec
* observede diffraction pattern- something is wrong with the camera, filter plate not moving, adjusting, fixed filter changing
* change exposure time to 0.3s, get star off center, focus on other, dimmer stars, adjust focus once more to see clearly
* discovered diffraction pattern in filter image
* took apart camera with help of Prof Boogert
* once camera filter in working condition, resumed observation
* took exposures of far field stars near Betelgeuse in order to focus the telescope
* shifted focus to plaidees - Atlas and Cleo
* used Astrometry in order to determine our location in the night sky
* once Atlas and Cleo found, took 0.1 interval exposures from 1 to 5 seconds until stars were saturating pixel value
* once pixel values saturated, shifted view to m41 orions nebula
* took one 7 second exposure

15/2/18 Began: 17:30
Started up telescope & opened observatory. Connected to camera with maximdl (disabled camera 2), turned on cooler to -15.
Found Capella @ LST=3:45, h= 22:27, rotated telescope mount. Changed declination to 46 degrees. Located star in viewfinder.
Began continuous 0.1s 4x4 binning image capture of CCD view. Moved telescope (speed 1) opposite to image view due to CCD being upside down, to centre Capella.
Go-to button used, caused telescope to move way off target. Recallibrating as a result. Now LST=4:15, so h = 22:57, relocated Capella. Centered etc.
With LST 4:27, Atlas found at h=0:32. dec 24 deg 6 min.
Used astrometry.net to work out stars from unknown image 1, located area in stellarium
Moved to bright stars (i.e atlas and pleione), checked again with astrometry and stellarium. Synced to Pleione HIP 17851 SAO 76229 on both telescope and stellarium (connected to telescope)
Centred on Pleione. Tested stellarium movement to other stars.
Centred on Atlas, took multiple images at several exposure times, saturating the image individually for both bright stars.
zeroed telescope, closed up dome.
Finished 20:00

Logbook for PH3010 Solar limb darkening mini-project, initial setup meeting
Present: DB, MA, JC, HS
Order of tasks for observation of the sun:
1) DO NOT STARE DIRECTLY AT SUN. DO NOT POINT UNPROTECTED TELESCOPE AT SUN
2) Go outside dome and check that sun will not be obscured by the tree, wind thingy. If it will be, will have to wait before able to take images of sun
3) Check solar filters are not damaged. Fit solar filters to main scope (and if using finder scope, fit solar filter to that). Fit CCTV lens to camera, camera to filters, filters to telescope.
4) Open dome, move opening so that allows shadow of telescope to be seen on dome wall
5) Use the shadow of the top scope (the one secured by two sets of three prongs) to align the telescope with the sun. When the shadows from both sets of prongs overlap, the telescope is (roughly) aligned with the sun
6) If using finder scope, use to target edge of sun.
7) Use IC Capture program to view camera feed (really need to jam the cable into the back of the camera to get the pc to detect it). In device-properties can control gain and exposure settings
8) Use live camera feed to target edge of sun and focus (unlock and use know on back of telescope)
9) Change declination of telescope and monitor live camera feed. Need to find centre-line of sun. This is when any change in declination results in the suns edge moving out of frame (away from centre, only changing declination in one direction will move it out of frame - the other will move it more in frame)
10) On telescope control setup-targets-terrestrial or astronomical
terrestrial will keep telescope at fixed angle, astronomical follows objects through the sky
11) Choose filter to image with. Point telescope as closely as possible to centre of sun and view image histogram. Adjust and exposure until the image is not fully saturating (has a narrow yellow bar - the zero readings - visible) but has as full a range of values as practical.
12) Return telescope to point at edge of sun, in the centre. In IC capture go to the timed capture settings. Choose an appropriate target folder and image capture filenames, set the image type to bmp, turn the 'auto display capture' to off and set an appropriate capture interval and number of captures.
Note: Sun subtends an angle of about 0.5 degrees. Previous years have taken 405 seconds worth of images for this project.
13) capture images. Repeat step 11 onwards for another filter

* Dome entered 10am. Present: MA, JC, HS, supervised by Dr. DB
* Telescope cover removed, solar filters put on
* camera and colour filters were already attached to telescope. setup checked just to be sure
* Telescope setup reviewed+approved by DB
* Dome doors opened, telescope turned on
* Moon was still visible in sky - dome doors moved to allow viewing of it
* Moon used for focus (coarse and fine), took a couple of images of nice craters
* Moon found by (roughly) lining it up with the telescope, then with the finder scope, then with the camera image
* Dome doors moved to allow viewing of sun, telescope slewed to find sun
* telescope shadow aligned on wall behind telescope
* telescope moved to bring the two rows of knobs into alignment (i.e. telescope pointing at sun)
* Using camera feed, approximate equator of sun found at one edge
* Test images taken
* Moon and test sun images stored in focus_images folder
* Colour image sets taken.
* All image sets performed by pointing telescope ahead of suns motion and switching to terrestrial mode - motion of sun across sky then carries sun across the frame of view.
* All image sets taken over 3 minutes 10 seconds. This time determined by timing a test run of the method.
* 1 image per second taken for the length of the image set.
* Used maximum gain for all image sets. Exposure determined by manually slewing across the sun and trialling different exposures. Aim was to get as close to having maximum pixel values in the image, without actually having any maxed out pixels
* Where necessary, solar eclipse glasses were used to directly view sun e.g. to determine if clouds were obstructing the sun, or just the area around it
* Clear Filter 1:
* Gain 799, exposure 1/1000 seconds
* trees obstructing parts of image set - produces obvious errors in dataset
* Clear Filter 2:
* Gain 1023, exposure 1/4000 seconds
* Blue Filter 1
* Gain 1023, exposure 1/154 seconds
* Some obstruction of sun by clouds
* Blue Filter 2
* Gain 1023, exposure 1/154 seconds
* Still some clouds, but far fewer than with Blue Filter 1
* Green Filter 1
* Gain 1023, exposure 1/308 seconds
* Lots of clouds
* Green 2
* Gain 1023, exposure 1/308 seconds
* Even more clouds
* Red 1
* Gain 1023, exposure 1/1241 seconds
* A few false starts (so the file indexing is messed up), but managed to get a good run of images
* Was not able to perform another run with the green filter, due to increasing cloud cover
* Dome doors repositioned above door to roof and closed.
* Solar filter removed and lens cap replaced. Filter stored back in its home.
* Telescope returned to 0h0d
* NOTE: Minor mix-up with imgae file names. All image sets are stored in the appropriate folders / .zips for the colour filter used, but the some image sets use the wrong colour name in the individual image filenames. Recommend handling image sets carefully / renaming appropriately when used.

* Present JC, AD
* Began cooling at 16:45 to -12 deg C (~90%)
* Filter wheel set to Clear, Red, Green, Blue
* Centred on Capella and took GPS-fix. Encountered problem: telescope believed it was -1h RA from Capella however this offset was constant.
* Edit: This seemed to just be an issue with the coordinates read-out on the paddle.
* Centred on M35 and took 1000x0.1s exposures to focus.
* Then took 60s exposure- significant effects of moonlight on image- change target to M36 (RA/DEC: 05 37 13.8/34 09 04)
* Light pollution significantly reduced suggesting moon was indeed the source.
* took 60s and 90s exp in all filters
* moved to (RA/DEC: 05 37 31/34 07 50) and repeated.
* took dark and bias frames before finishing observation at 9:30pm.

PEC Training
Meade LX200GPS Pec Training
- Setup -> Telescope -> RA PEC -> Training
Method
- Connect to Stellarium and MaximDL
- Telescope pointed at Vega synced
- Moved to Epsilon Lyrae (epsilon_lyrae)
- Camera disconnected from MaximDL and connected to PHD Guiding
PHD Guiding keeps the star in the same position at all times allowing the PEC to be trained
Data read with PEC Editor (MyScopeShort) and saved as *.txt file for further analysis
PHD Settings
1st PEC
- RA_PEC_DATA1.TXT
- 0.2s
- Default Advanced Settings with:
- Full Frame
2nd PEC
- RA_PEC_DATA2.TXT
- 0.2s
- Default Advanced Settings but:
- Subframe
Processing Code:
- To be added
Plots for PEC Data:
Test images:
NGC6675 (Spiral Galaxy) - 1 (ngc6675_possible) and 5 min (ngc6675_definite) exposure, 2x2 Binning
M57 (Ring Nebula) - 1 min exposure, 2x2 Binning

Focus and Filters
Average filter wavelength
- Blue: 450mm
- Green: 550mm
- Red: 650mm
ST-8ME Quantum Efficiency:
- Blue: 55%
- 1.82x exposure from clear
- 60s clear -> 109s
- Green: 70%
- 1.43x exposure from clear
- 60s clear -> 86s
- Red: 75%
- 1.33x exposure from clear
- 60s clear -> 80s
Test Images
M57 - Ring Nebula
M56 - Globular Cluster
- 1x60s Luminance image
M27 - Dumbbell Nebula
- 9x60s Luminance images stacked to form a 6x60s image
- 1x109s Blue image
- 1x86s + 2x60s Green images
- 1x86s + 5x60s Red images
During the Dumbbell Nebula imaging the filters were accidentally changed due to the mouse scroll.
- Possible workarounds:
- Use autosave function to take images
- Check before taking a new single image

APIs:
* [[http://seal.web.cern.ch/seal/documents/minuit/mnusersguide.pdf][Seal Minuit]]
* [[http://iminuit.github.io/iminuit/api.html][iMinuit]]
*Performance (measured with Python %timeit() magic function):*
* PyMinuit: best of 3: 13.9 s per loop
* iMinuit: best of 3: 11 s per loop
*Conclusions:*
* iMinuit is easier to install than PyMinuit
* iMinuit is faster than PyMinuit
* iMinuit have more features than minuit (e.g. export to LaTeX and fake functions)
* Both detected and successfully minimized a 2D Gaussian on all the stars with same parameters
* PyMinuit "accidentely" fitted more Hot Pixels than iMinuit
* PyMinuit includes Simplex and Scan methods, which are not available on iMinuit
* PyMinuit is more stable - annoing bug in latest version cause segfault it limits, steps, ... are not set
Keep PyMinuit for now.

| Created: 10 Sep 2013 16:48:33 | Last Revised: 11 Sep 2013 15:49:16 | Public.PedroPaiva | Building Python on cygwin |
pre-requisite: have [[http://www.cygwin.com/][Cygwin]] installed and a GNU compiler.
Cygwin comes with python pre-installed, from there one can install new packages with:
* easy_install packageName
* pip install packageName
To use ==pip== you must install it first using ==easy_install pip==
The ==pip== method is favorable for it allows you to search, uninstall and upgrade packages easily.
==pip== guide:
* ==pip freeze== - display currently installed packages
* ==pip search packageName==
* ==pip install packageName [--upgrade]== - installs or upgrade an already installed package
* ==pip uninstall packageName== - uninstall a package
*Packages installed*
* ipython
* numpy
* scipy
* pyfits
*To be installed:*
* matplotlib
* opengl
* pyside
* pywin32 (don't support cygwin)
* pyminuit ([[http://code.google.com/p/pyminuit/wiki/HowToInstall][detailed guide]])
1 Download the required files: [[http://code.google.com/p/pyminuit/downloads/detail?name=Minuit-1_7_9-patch1.tar.gz][Minuit-1_7_9]] and [[http://pyminuit.googlecode.com/files/pyminuit-1.2.1.tgz][pyminuit-1.2.1]]
1 Extract and change to Minuit directory (under cygwin)
1 Compile Minuit with:
1 bash configure
make
make install
1 Change to pyminuit directory ( ==cd ../pyminuit-1.2.1== )
1 Build and install with: ==python setup.py install --with-minuit=/location/of/Minuit-1_7_9==

Ring Galaxy (NGC1291)
Protostar (IRAS 20324+4057) "The bizarre looking ring galaxy NGC 1291 in Eridanus.
These fairly rare types of galaxy are usually much fainter objects, but this one at "only" 33 million light years away is easily visible in modest size telescopes though the faint outer ring of material is much fainter than this.
Its strange appearance is the likely the result of a collision with another galaxy in the distant past.
20"CDK with FLI-PL6303e camera. LRGB. L: 70mins. RGB: 5/5/10mins" - Damian Peach
IRAS 20324+4057 is a Protostar in the Cygnus OB2 Association, 4,500 light-years (1,380 parsecs) away.
This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
INT: H-alpha
cyan ACS: F606W (V)

After turning telescope on, it successfully received GPS signal and did not started the usual RA movement.
The Camera was connected to Python via MaximDL
Telescope and Focuser connected to Python via the POTH Hub
Coordinates in agrement between Scope, Python and Stellarium
Target was set to be -0.1º RA from current telescope position and Python SlewToTarget was tested.
Telescope moved the right amount and stopped, both telescope and Python alerted when ready.
A second test was made with +0.5º RA. Also successfully.
Still with small (-0.1º RA/DEC and +0.5º RA) movements, Python SlewToCoordinates was tested successfully.
With the tests done, the telescope was moved to Vega via controled movements on Stellarium
Vega was inside the Camera Range, demonstrating that the Park Method works.
Vega was recentered (-0.01 on RA) and the telescope was manually synced.
During this test, movements as small as 0.003º on RA proved to have no effect whatsoever.
The next step was to test the focuser and the camera.
First, while still on continuous mode of the camera, the Python-Focuser connection was tested.
Python can read the position and move the focuser. Units are steps. 1 step = 20µm
Having confirmed that one can move the focuser with Python, Vega was taken out of focus to test if we could focus the star using a small

prin = True

POTHFocuser.Move(step)
while POTHFocuser.IsMoving:
if not prin:

*Focus movements*
* Positive -> In
* Negative -> Out
*Tests*
The data below have a significant experimental error associated with the not fixed measuring equipment.
Also, they can have errors related to a possible angle between the measuring equipment and the in-out axis therefore, the real value would differ by a factor of cos(theta)
*out*
* move(-5000) - 1.86mm
* move(-5000) - 1.80mm
* move(-5000) - 1.86mm
* move(-5000) - 1.81mm
* move(-5000) - 1.88mm
* *mean = (1.842 ± 0.031)mm*
* move(-1000) - 0.31mm
* move(-1000) - 0.40mm
* move(-1000) - 0.44mm
* move(-1000) - 0.27mm
* move(-1000) - 0.45mm
* *mean = (0.378 ± 0.076)mm*
The out movement is coherent and 5000 steps is indeed equivalent to 5x1000 steps
This give 1 step aprox 0.37µm
*in*
* move(5000) - 1.52mm
* move(5000) - 1.55mm
* move(5000) - 1.52mm
* move(5000) - 1.48mm
* move(5000) - 1.57mm
* *mean = (1.528 ± 0.031)mm*
* move(1000) - 0.21mm
* move(1000) - 0.20mm
* move(1000) - 0.15mm
* move(1000) - 0.30mm
* move(1000) - 0.18mm
* *mean = (0.208 ± 0.050)mm*
The in movement is 25 to 50% smaller than the out movement (depending on the movement size) with larger movements closer to the equivalent out.
This give 1 step being between 0.2 and 0.3µm
*Conclusions*
The execution of the above movements led to the following conclusions:
* Focuser always finishes in a 'in-movement' (e.g. asking to move out will make the focuser goes more than needed and come back about 1mm)
* This causes the isMoving check to return before the focus being ready.
* Focuser limit less than aprox 30k steps when going in.
* When close to the limit, focuser will overstep (move(5000) caused the focuser to move 2.76mm)
* Focuser isn't ready when isMoving returns False.
* There's a time gap when a second comand will be accepted but not executed.

[[http://www.newastro.com/book_new/ebook/c2d.pdf][Diffraction aids]]
---------+++ Using a Bahtinov mask to find the focus:
Based on Laurie's idea and [[http://starryvistas.net/articles/focusmask/focusmask.aspx][this article]] a set of 144 images were taken.
3 images for each of the 48 moves made by the focuser. All the movements were 'in' moves of 250 steps.
The images had a 5s exposure time and a master dark (made of 10 dark) was made and reduced from the images.
On each image, a gaussian was fitted to the brightest star (142/144 success) and the amplitude and sigma median were taken for each set of 3 images per focuser position.
The data was then plotted and assumed to be in a quadratic form. The results can be seen on the images below.
For the Sigma X values, the minimum can be found at: 4841 steps
While Sigma Y minimum is at: 5411 steps
And the Amplitude maximum at: 6804 steps
According to [[LogBookAstronomyEntry0015]], the 2000 step (aprox 600µm) difference would be more than double the depth of field for the telescope [[http://starizona.com/acb/ccd/advtheoryfoc.aspx][(287µm on a f/10)]].
A visual analysis of the graphs would suggest a minimum and a maximum for Sigma Y and the Amplitude close to 6000 steps and, visually, the image at step 5750 (image set 23) is the sharpest presenting a nice 'X' diffraction pattern produced by the Bahtinov mask.

* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* Attempted Installation of Python Canopy on personal laptop to begin data analysis but fails to install on Windows 8.0 (Attempting update to 8.1 to see if it rectifies issue) [Installed 32 bit version instead]
* Set temperature value to -07.5 deg C, left for 30 - 40 mins to stabalise.
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* For data analysis will need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.

Using Autosave feature to speed up process, Hence file format has changed to: T-10.0-001-E0001
Must go back to data taken on the 18/10/2013 and rename files for consistancy -> Done.
Proceeded to take another 120 dark frames at -7.5 degrees, as with coolers on 100% sensor temp would not go below -10.6 degrees.
Proceeded to take anothe 120 dark frames at -2.5 degrees.
CCD will then be reset to 0 degrees, and frames will be taken every 30 seconds as it is cooled from 0 to -10 degrees. The exposure time will be 2 seconds. Due to lack of time this will be postponed until next week.

---------+ Project meeting on 24 / 10 /2013
Present: Chris Haynes, Paul Hallam, Ryan Cheale, Dr Boogert, Professor Cowan.
Continued discussion on taking and analysis of dark frames.
Due to the dome not being cold enough during the day, it is difficult to cool the camera down to -15 or -20 celcius. Therefore, the remaining readings will be taken further into winter, when the dome is colder.
Objectives for analysis of dark frames:
* Plot a histogram of the -5°C, 60 second frame and compute the mean, median and standard deviation.
* Plot the column mean and consider the standard deviation for all columns.
* Plot the standard deviation as the square root of the mean and check to see if it's a Poisson Distribution.
Additionally, we should think about the dark current rate (the rate at which an electric current is generated in the chip due to the production of electrons and holes) and how to compensate for it.
We should also consider what the faintest star we could detect would be, looking at the point spread function of our telescope.

---------+++ Activity Log
* Took off cover for telescope & Camera
* Turned on Camera and followed steps detailed [[Students.UnderGraduates.RyanChealeCameraTechnicalAspects][here]]
* Set temperature to -10 deg C, waited 30 - 40 mins for stable temperature
* Used Autosave Sequence located at 'Desktop/Data/20131016_RC/25darks60s.seq'
* Autosave feature allows running of each permutation whilst saving automatically
* Format T-tt.t - NNN - Eeeee.fit where T - temperature, t - temperature value, N - repetition (==20) , E - Exposure, e- Exposure time value (0.1s, 1s, 5s, 10s, 60s, 180s)
* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* turned off the coolers on the camera to allow it to reutn to room temperature.
* Proceeded to take data in 30s intervals for 30mins whilst turning the coolers back on and allowing the temperature to reduce to -10 deg C to see what effects allowing the temperature to stabalise has
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* For data analysis still need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.
Python
* Began the use of the canopy environment to begin data analysis in Python.
* Running into multiple problems with the canopy environment with plotting graphs
* Have made plots for the mean, standard deviation, max and min values of the data set T-05.0-NNN-E0600
* Struggling to create histogram plots, either the kernal or the environment tends to crash when trying to create a histogram of a single fit file
* Next steps:
* Produce median plots
* Refine code so only needs slight input alteration for other data sets
* Produce histograms and then further plots based off of the histograms
* begin analysis on cool down data.

A study into the variation of background pixel count with temperature.
Initial CCD temperature was recorded to be 18 degrees. Coolers were turned on and CCD cooled to 0 degrees over the course of an hour, to ensure the entirety of the CCD began at zero degrees for the following study.
Coolers were then set to cool the CCD to -10 degrees, and one second exposures were to be taken every 30 seconds for one hour over this cool down period.
The data shall be saved in the following format: Cooler_Study-001E001
Also this shall also provide 29s exposures between the 1s exposures, which shall appear like this: Cooler_Study-001E029. This data will not be analysed.
When this collection of data has been finished, CCD was at a constant -10 degrees. The CCD coolers were switched off, and the CCD warmed back up to room temperature. Using the same method, one second exposures was taken every 30 seconds for one hour over this period.
The data shall be saved in the following format: Cooler_Study_2-001E001
Again this will also produce data that will not be analysed, in the form of: Cooler_Study_2-001E029
Room temperature in this case is 25.6 degrees.

---------+++ Telescope Set Up
* Target Delta Cephei selected using Stellarium and AAVSO catalogs
* Open shutters (ropes, pull apart, tie off ropes, motor control
* Turn power on
* Press power switch on telescope
* Removelens caps
* Point towards Vega
* Line up with finer scope
* Take continuous frames 0.1s
* Center Vega in frame
* Synchronise Vega with Maxim DL and Stellarium
---------+++ Target Information
* Pulsating Variable star, magnitude variation 3.5 - 4.4, Δm = 0.9
* Period 5.4 days
* Next maximum, 07/12/2013, 9:32
* RA: 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From simulated light curve - expected Δm(max) = 0.26, expected Δm(min) = 0.01
* From light curve of Delta Cephei, and time of next maximum, we believe the magnitude should be decreasing
* Companion star HIP 110988 used as a reference star
---------+++ Initial Observation of Delta Cephei
* Centered on Delta Cephei - did not use Stellarium as could move telescope through the pole
* Frames were taken using different filters, initial exposure times:
* No filters - 1s
* Blue filter - 10s
* Green filter - 3s
* Red filter - 3s
* Took sample frames using this-set up, max pixel count was found using Python
* Re-evaluate exposure time to ensure max pixel count was in the range 55000 - 60000
* Re-evaluated exposure times:
* Focus filter - 1.1s
* No filter - 1s
* Blue filter - 10s
* Green filter - 5.1s
* Red filter - 3.3s
* Decided to take 5 repeats for each of these, and 10 repeats for Dark and Bias frames
* Autosave feature was used to take a sample set of data
* Residual image of Star found on Dark frames - low pixel count
* Implemented a 'Trash' frame before the Dark frame to attempt to remove this -> some residual image still remained
---------+++ Observation of Delta Cephei
* Autosave feature took approximately 10 - 15 minutes to run
* Approximately three runs were taken per hour
* Delta Cephei was observed for 5 - 6 hours
---------+++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope
* Turn off camera
* Turn off telescope
* Put cover back on camera
* Close dome shutters
* Turn off PC monitors
* Turn off lights and leave dome

20140213 LN
Reasonably clear and forecast to be good. Worth a try to get some practice in.
* CCD at -15oC
* Aligned to capella - very high in sky.
* Went down from 46 to 37 DE to theta_aur as capella saturates the camera.
* Take subframes to practice focussing. Recorded 400 frames of theat_aur for analysis later. SNR is good as super bright. Peak around 30000 ADU. Jumps around A LOT so will have to align by centroid. Then can have a look at PSF.
* Exposure 0.1s
* 300 exposures recorded in 10m12s
* 400 exposures recorded in 13m37s *Sat bhatinov mask carefully on front of scope. Recorded 50 images with same setup as before. Not so clear.
* Exposure 0.5s
* Not so clear. Pattern seems very small indeed on CCD compared to internet images. Collimation is definitely poor and its windy so don't expect it to be great. Anyway, reasonably good in focus.
* Having a look at the Pleiades. Too extended to see anything nice and certainly with the seeing. The stars are very bright and the nebulosity not so, so quite hard to observe under these conditions.
* Imaged Andromeda ok. 30s exposures.

Using the spectrometer to find the brightest spectral line in mercury and Find the best micrometer reading for the angle of the camera.
Camera was ST-7E, Setup SBIG Universal.
Temperature for all the images was -6.5 deg C.
*Focus*
Exposure time: 0.1s; Grating distance 1.814mm; Camera angle micrometer reading 2.495 (heavily sloped)
Used continuous range to find a reasonable staring point.
Used range of 18mm to 20.5 mm in steps of 0.5
Reduced range to 19mm to 20.5mm in steps of 0.10
Reduced range further to 19.50mm to 19.80mm in steps of 0.05
*Camera Angle*
Exposure time: 0.1s; Grating distance 1.814mm; Focus distance was 19.60mm for this
Used continuous range to find staring point.
Used range of 2.50mm to 5.50mm in increments of 0.5mm to start.
Reduced range to 4.00mm to 5.00mm in steps of 0.10mm
Reduced range further to 4.45mm to 4.65mm in steps of 0.05mm
Found the best angle to be _4.60mm_
*Brightest Peak Data*
Looking through the spectrum the brightest peak, found at 4.00mm in grating micrometer.
This was saturated so the lamp was moved back by 5cm which was still saturated, then we moved it back by another 5cm which put the lamp back from the optical fibre by 25cm. This reduced saturation where refocus was done. Seemed to saturate at 50,000 confirming it was brightest peak.
Used this to check the focus and recalculate.
used a range from 19.50mm to 20.50mm in steps of 0.10mm
Found best focus distance on micrometer to be _20.10mm_

27th Oct 2014 Msc Observation.
*Begun:* 18:30
*Finished:* 22:30
Conditions: Mostly clear, a little muggy. No cloud coverage.
Begun observation session with a run down of the procedure to prepare the dome.
*Dome Procedure:*
-
Enter dome
- Close the hatch to prevent heat rising and entering the dome. The floors beneath are heated which causes a ‘chimney’ like effect if the hatch is left open as the hot air from below will rise up through it. Ideally the scope and dome should remain cool so noise due to thermal fluctuations is kept to a minimum.
- In the Maxim DL suiteconnect to the telescope. This allows control of the camera for example you can set exposure times and capture images from the program.
- Enable the CCD cooler in Maxim. This should be done ~1 hour before taking exposures. If you take observations too soon after enabling the cooler you get a ring like effect on your observations around the outer area of the frame. The ring progresses further to the sides of the frame as the CCD cools until it eventually disappears.The set-point of the cooler is set to -10 degrees celcius and the CCD itself fluctuated around this point slightly once the cooler had taken full effect.
- Untie the ropes that control the shutter of the dome. Pull on ropes to open the shutter of dome, if the shutters do not open with ease, there is a long stick with a metal prod at one end which can be used to manually push the shutters open from near the top of the dome.
- Once shutter is open, tie the ropes off again to make sure that they are kept out the way of the moving parts of the done which can rotate bothe counter and clock-wise
- Using the door on side of dome, go outside and do some preliminary naked eye observations to find an interesting object to observe (this is important for aligning the telescope as detailed later on). This allows you to plan roughly where the telescope and open shutter should be pointing to allow unrestricted viewing.
- Using the dome control unit, align the dome opening with what you want to observe.
- When finished observing, realign both the dome and telescope to their origional position. Close the dome shutters and tie up the ropes.
To begin making observations you need to align the telescope to a bright object in the sky and then enable tracking. Tracking corrects the position of the telescope relative to the sedereal motion of the stars. This is necessary because the field of view of the telescope is so narrow if it was left stationary, the object you are observing will move out of frame. To align the telescope, the first step is to identify a bright object visible to the naked eye in the nights sky. You can acess the roof from the dome via. the door on the side. Once on the roof you are able to evaluate potential targets. We identified the star Vega (25ly away, 2.1M0, alpha lyrae - the brightest star in the lyra constellation and 5th brighest in the night's sky). The star charts provided in the program stellarium coupled with manual positional measurements allow you to identify the star you are looking at with the naked eye.
Once a object in the sky has been chosen, the next step is to align the telescope to enable the activation of tracking.
- *Telescope Alignment:*
-
Use a high speed on the control paddle (speed button -> 9 is fastest, 1 is slowest on number pad) to crudely align the scope with what you want to observe using the arrow buttons. This can be done roughly by eye by lining up the two bolts on the side of the telescope with what you are looking for.
- Then use the viewfinder which has a set of crosshairs to align the scope more accurately with the object in the sky. A medium speed setting on the paddle can be used to move the scope with a greater deal of precision.
- Once the crosshairs are centred on the object you wish to view, take an exposure in the maxim DL suite. Once the image has been taken and downloaded you can adjust the scope to get the object centred in the frame. If you set maxim DL to take continuous ~1s exposures you can get a better sense of the best way to align scope and object.
- Once the scope is aligned, enable GPS lock. This continuously corrects the scope to account for the rotation of the earth. The field of view of the scope is very narrow causing the object you are observing to move through the frame if the scope remains stationary.
- Once tracking is enabled, the scope should keep the object you are trying to view in frame automatically.
- Using the control paddle, tell the telescope which star/object it is currently aligned to
- With the telescope connected to stellarium which now allows you to control the scope through the program itself. Using the star charts, you can align the scope to stars/objects shown in stelarrium. (Wait for the ‘beep’ if you move the scope in the program. The scope moves quickly at first but then makes finer corrections to ensure the scope is aligned well. The 'beep' occurs once the telescope is properly aligned, it can take some time ~20-30 secs).
- While repositioning the telescope it is important to be aware of it's orientation with respect to it's base. The telescope is capable of flipping over on itself which can cause the CCD attatchment to collide with the stand. In a situation where this may happen, power down the telescope via the power controls located on its stand immediately.
With the telescope aligned you can control where it is looking via. the stellarium program. Multiple exposures of Vega were taken at different exposure lengths using the Maxim DL program.
Using stellarium, the telescope was then trained on the open cluster M-39 in the constellation cyganus (800ly away from earth). Again took multiple exposures. The cluster is composed of a number of stars. Using the star chart in stellarrium the star patterns were compared to that shown in the exposure allowing for individual identification of the stars the cluster is made up of.
You have the ability to manually focus the telescope. If it is out of focus the exposures of stars can present as donuts (dark centres with bright outer ring) or they seem flat and blurred at it's edges. The procedue to manually focus the telescope is first to 'unlock' the mechanism. There are two dials, the shorter one can be rotated to unlock the device allowing the second longer dial to be turned focusing the telescope.
Last target of the night was the andromeda galaxy known as M-31 (as it is a messier object) and is 2.5x106 ly away from earth and the closest spiral galaxy to the milky way group. This galaxy has a mass ~ 1.5x10^12 M0. 10 exposures were taken one after the other with the intention of eventually using them to form 1 image with considerably less noise.
An interesting point to note is that movement of the atmosphere above the telescope can cause exposures to shift in and out of focus. This was made evident as during continuous exposures of M-39, the stars were alternating between being in focus and out of focus.
The exposures taken during the night of observation are attached to this post.

*Observations of the Spectrum of Betelgeuse*
Started looking at Capella. Using a small sheet of tracing paper to allign the star in the optic fibre coupling. With Capella at a high Altitude we switched to Betelgeuse as a target to make allignment easier.
Viewed Capella at
5hrs 20' 30'' RA
45deg 8' 2'' DEC
with the micrometer at Grating-4mm, Angle-3.25mm, Focus 20.2mm.
changed the RA 5'' either side to align it centrally while observing the intensity recieved.
*Betelgeuse*
Next look at Betelgeuse,
5hrs 58' 32' RA
6deg 25' 30'' DEC
Took a 30s exposure at 4mm to look at the spectrum as best as possible. Then took 60s exposures of Betelgeuse between 0mm and 10mm in steps of 0.5mm.
After Betelgeuse we briefly moved to the Orion nebula however it was too dim to observe.
*Pollux*
7hrs 46' 14'' RA
27deg 59' 18'' DEC
Again took 60s exposures from 0mm on the grating position micrometer too 10mm in steps of 0.5mm.
Laurie left at 23:00
*Castor*
7hrs 35' 22'' RA

Please edit and put your text etc. here
Start Time: 19:00
Conditions: Slightly cloudy at start, quickly became clear around 8pm and remained clear.
Observations:
*Castor (Alpha Gem)*
Aligned to Castor, RA: 7h 34m 35.87s, Dec: 31dg 53' 17.82" Apparent Mag: 1.93
Ring visible due to cooling of CCD chip taking place.
*Near Castor*
Observed multiple stars near Castor with low magnitude (10 - 15)
No images taken.
Ring still visible.
*NGC2388*
Centred on galaxy NGC2388, Apparent Mag: 14.
NGC2388 was chosen as a target as it is known to currently contain a Supernaova of Apparent Magnitude 15. See http://www.rochesterastronomy.org/snimages/snactive.html
Supernovae: PSN J07285387+3349106, RA: 07:28:53.87, Dec: +33:49:10.6, z = 0.013790
One frame was taken at 120s exposure. Stars were cross checked with Stellarium and were found to be low magnitude (10-16). Two other galaxies were also clearly visible, NGC2385 and NGC2389. The cooling ring was still visible at the edges of the frame. This location was chosen for the target of this observation due to the number of low magnitude stars, and the presence of three galaxies.
Uploaded a frame to astrometry.net
Experimented with 180s exposure, decided to use 120s.
Stacked frames using MaximDL built in image stacker to invstigate noise reduction.
Images taken:
Data was taken in bursts of 9 images, 3 Light Frames with 120s exposure, 3 Dark Frames at 120s exposure and 3 Bias frames.
Dome was realigned every 2 bursts to ensure unobstructed view of the sky.

---------+ 2015 05 20 LN DSLR Observation
* Trying out DSLR on back of scope
* Benefit - easy live video to investigate focussing, wide field of view
---------++ 20:30 start
* Dismounted SBIG camera (in case)
* Canon DSLR bayonet adapter + BADER 2" - T/2 Nosepiece on back of micro-focuser
* Observed Moon, Venus & Jupiter during twilight ~ 21:40
* Aligned & synchronised to artturus star to the south as visible to the naked eye
* image of M3 globular cluster ~ magnitude 6 - can make out ok in photos but still blue sky background as still slightly light
* 2155
* Trial of Deep sky object - still lightish but will keep iterating over objects
* Bodes Nebula mag 6.9
* Of note is that the DSLR is slim enough for a polar flip of the mount. Haven't, but can.
* Whirlpool Galaxy
* Getting better images but can only really see core of galaxy - still to much sky glow
From images of a single bright star or say of Jupiter and it's moons, you can see what appears to be both coma and chromatic aberration. The edges of non-point like objects have an orange tinge on one side and a blueish tinge on the other. Jupiter is relatively low just now so there is a strong affect from the atmosphere / imaging but still Jupiter had an asymmetric tinge. The moons were also quite distorted. Although the 'live view' gives you some indication, it simulates the exposure settings and can distort the image a little. Best to take images directly and zoom in to compare. Not too different from live view though.
* Telescope likely needs collimation, but the trouble is finding a good enough night for to be able to observe any improvement.
Sky much darker now. While no clouds around, there is a bit of haze - can't see huge multitude of stars.
* Starting at 3845 images of great cluster in hercules.
Finish at 22:20

---------++ *Before taking data*
* Time of turn on: 18.20.
* Cooler set to -7 degrees.
* Temp at -6.9 degrees at 18.30.
* Center the telescope on Vega.
* Aling the telescope to Vega. (~Mode on the controller)
* Speed 5 and later 3 on controller while focusing on Vega.
* Microfocuser used to fine focus.
* Speed 3 to place Vega in the center of the image.
---------+++ Alpha Persei Cluster (Cr 39, Mel 20)
* We chose our cluster as the Alpha Persei cluster.
* To focus on the cluster we chose a nearby bright star Mirphak.
* We used it to correct our ofocusing and we synched Stellarium wityh the telescope.
* We choice a patch of the cluster (HIP16001) and took 10 vimages of 10 second exposures. ( x binning set to 1, x anmd y originally inverted, this was reversed)
* 5 bias frames and dark frames of 5 1min exposure.
* Took 3 40 s red.
* Took 3 40-s gtreen.
* Took 3 90 s blue.
*
* Move to a different patch (around RA:3h29min29s, DEC:49deg44'16")
* Ian joined us at 20:00
* 3 images of 60s visual.
* 3 images of 120s red.
* 3 images of 120s green.
* Finished taking data at 8.30 pm.
---------+++ Dark and bias frames
* Started taking dark frames. 5 images of 120s.
* Take 10 bias aswell.
Observation finished at 8.56pm.

The aim of the session was to modify the parameters of the camera. Using only OpenCv it was impossible to set the camera's parameters with known units.
py-ic-imaging-control was downloaded from: https://github.com/morefigs/py-ic-imaging-control
py-ic-imaging-control is a python wrapper for the IC imaging control software development kit from the imaging source (TIS). It provides control to TIS cameras, and can serve as an alternative to using OpenCv to access the cameras parameters.

The DMK camera was fixed to a tripod and pointed at the moon.
Run1: Gain set to 180 and images were recorded of the moon at a frame rate of 7.5 frames per second. The algorithm left the exposure setting on 1 as the image was not over or under exposed on this setting.
Run2: Gain was increased to 1023. The images were over exposed and the algorithm accounted for this by changing the exposure setting in increments of 1. It was noted that this was very slow to respond to large and sudden changes in conditions.
Run3: The code was modified such that the amount the algorithm changed the exposure setting depended on the number of pixels that were saturated. This massively decreased the time the algorithm took to find the correct exposure setting. See screen shot.
Images were also taken of Orion's Nebula, see image file names for parameter settings.

Az/Alt: 318deg 44'20''/38deg34'50''
Took testing pictures: Cooling_1 and cooling_2, can be seen a ring surrounded by the ice. Secong image shows larger ring, meaning hte camera is cooling down
Cooling_3 image is clear and even
Checked the wether with met office, clouds are exopected to clear for the rest of the night
Finding the star by eye, alighning the tescope, using stllarium found it was Procyon
As it wasn't clear that the star is Procyon, checked with Rigel
Took images of the delta cep with no filter and with filters: red, green, blue and spectroscope. Aimed for 50 000 pixel value - the closest to the maximum possible p.v.
Exposure time was increased as different filters were applied, because different filters obsurb more light.
Cloudy weather led to taking many pictures for blue filter with longer exp time, 16 sec.

Please edit and put your text etc. here
---------+ Finding focus of optical fibre
* The focus of the optical fibre was found by taking a relative distance between the lens and the position of the optical fibre, and measuring the amplitude of a spectral line from the laser found at 3.5mm.
* taken at 1mm intervals between 230m and 270mm.
* Fit with hyperbolae as approximation
* distance measured with ruler so very approximate i.e ±1mm
* Best focus was found at 250mm±2mm
* Iris was almost closed as the laser would saturate camera at shortest exposure.
* also took more data as SBIG ST-7E was cooling.
* Just need extra part to connect firewire camera, so that the alignment can be competed.

Please edit and put your text etc. here
---------+ Focussing Beam Splitter
* To find best focus should be able to focus onto a single fibre, once one illuminated, in focus. will have to use extension rings for optical fibre.
* CCD camera can then be adjusted until in focus.
* Focus by shifting backwards and forwards on rails.
* Find focus of camera with max intensity and minimum width of laser.
* Use diffuser or neutral density filter, will need neutral density filter.
* Make two plots of intensity on camera and fiber and adjust until peaks overlap.
* Such that there are two plots which look similar to:
---------+ Aligning Beam Splitter
* Align by moving the mirror horizontally and vertically until maximum intensity
* possibly get 3 more irises, to control aperture at camera, fibre and entry, to make sure always have good alignment.
* As now in focus, can scan around fibres and find the relative positions compared to the end where they are arranged into line.
* This could help with finding best position of ray on camera
* Look up mirror and see how much change in angle before lost fibre, one full turn until laser out of view.
* try to get two irises as far away from each other for best alignment.
* once part for CCD arrives, move around and find relative positions on camera to positions on optical fibre.
---------+ Relating to telescope
* Have to use larger beam size so that f# is the same as the telescope, f# = 10,
* currently 3 dioptre lens, so 1/3 m focal length, this means need a beam diameter of 33.3 mm or a longer focal length.
* as , where f is the focal length, d is the diameter of beam or aperture and f# is the f number.
* consider which camera to be used.
* beam splitter reflects 30% and transmits 70% so check this.
---------+ testing intensity
* tested the intensity at reflection and transmission, with diffuser and tissue in front of laser, tissue made intensity vary substantially so averaged over five frames, the reflection intensity was found to be 3% of the transmission intensity, however there could be problems with focus and alignment at the refection, need better analysis of this.

---------+ Aligning Camera and optical fiber
* Spectrum images,
* Exposure: 0.1s
* Temp: 10 deg
* used subframes around spectral to speed up
* FireWire camera * Exposure: 1/500 s
* The FireWire camera was attached to the beam splitter and connected to IC capture
* Optical fiber was attached using a spacer to approximate the same focal length as the FireWire CCD
* Initially an approximate focus was found on the FireWire camera.
* Then the angle of the mirror was adjusted vertically such that the laser beam was scanned vertically.
* images of the position on the CCD and the spectrum were taken at a range of positions.
* The amplitude of the spectral line was then recorded with position on the CCD.
* This gave a plot shown below for the maximum intensity. i.e centre of fiber
*
* This was then repeated for a scan horizontally, which gave the plot below.
* The best positions were found to be at [190,218] pixels, i.e 190 pixels across and 218 pixels down
* The the focus of the image was to be found.
* The box which the beam splitter and camera is attached to was placed on the rails and scanned backwards and forwards using a ruler for approximate focal length.
* Images were recorded for both the camera and optical fiber, and the amplitudes were plotted against focal length.

Please edit and put your text etc. here
---------+ Alignment of Camera and Optical Fiber
* SBIG camera,
* Temp: 10deg
* Exposure: 0.1s
* subframe around fibers
* FireWire Camera,
* Exposure: 1/500 s
* Took focus measurements first by moving beam splitter to find best focus.
* Best focus was found by subtraction background of spectral line image and summing pixels
* Best focus for image was found by finding max pixel value
*
* The optical fiber focussed ~6mm from the FireWire camera
* Optical fiber was adjusted such that it is as far out as possible using the smallest spacer, and the camera was adjusted so that it was as close to the beam splitter as possible.
* This was to close the 6mm gap found earlier
* The fiber and camera were then realigned as the FireWire camera will have been rotated slightly and moved out of alignment.
* Both horizontal and vertical alignment were used and the best positions were found at maximum intensity the same as for the focus.
*
---------+ Attachment of guidescope
* Two mounts for the dovetail plates attached on the top of telescope, plate then attached.
* The two dovetail plate mounts for the bottom of the telescope have to have small section removed due to bolts on the telescope which were in the way.
* Bottom dovetail plate then attached.
* guidescope rings and guidescope attached to the top plate
* counterweight attached to bottom.
* The telescope was then approximately balanced by adjusting the counterweights position on the plate and by unscrewing the counterweights so they were further from the OTA.

Please edit and put your text etc. here
---------+ Alignment of fiber horizontally and vertically
* SBIG camera for spectrometer:
* Exposure: 0.1s
* Temp: 10 deg
* Subframes
* FireWire Camera:
* records video at 30fps
* Exposure: 1/500 s
* Approximate focus was first found. set at 255 mm
* The mirror was adjusted horizontally such that the laser moved horizontally in the camera frame.
* Images were then taken of both the spectral line of the laser and the image on the FireWire camera as it was scanned, 40 images were taken.
* The maximum intensity of the beam and its position were recorded on the FireWire camera and the summed intensity was recorded for the spectrum with removal of backgorund.
* The intensity on the spectral line was then plotted against the position on the FireWire camera, this gave a plot shown below.
* The peak position on the above plot is then used to set the position of the beam on the camera, which is approximately at a position of 200 pixels.
* Once the position has been set the process was repeated scanning this time vertically, this gave a plot as shown below.
* The best position for the beam to be on the camera for max intensity at this stage is then at pixel values [200,216].
---------+ Focussing the beam
* Once the beam has been set to the best position as found earlier the camera and optical fiber were adjusted between distances of 220mm-290mm in 2mm intervals to find the best focus.
* Here the same measurements as before were made. The intensity of the spectral line and the maximum intensity of the FireWire camera are plotted against focal distance.
* The plot of both the camera and optical fiber is shown below.
* With this image the approximate best focus was set at 250mm
---------+ Repeat of alignment
* The alignment process was then repeated as before, this gave the below plots.
* These gave maxima at a pixel position of [201,217], The image below shows the position of the laser of the camera at this point:
---------+ Horizontal Scans at different Focal lengths
* For 6 different focal lengths, 240,244,248,252,256,260, a horizontal scan of the laser was recored on the camera and the spectrometer. This range was chosen as in the above focus plots, this is where the intensity flattens.
* For each of these the position of the laser of the FireWire camera was plotted against the total intensity of the fibers.
* The aim was that the focal length which gives the smallest width of a spectral line is the correct focus.
* The plot below shows the intensity plot for each of the focal lengths, and the widths of the line.
* This shows the widths does not change much in that range, this could be due to the fact that the focus is smaller than the size of the optical fiber, therefore, the integrated amplitude will remain the same in this range.
* Therefore, by selecting a single fiber to integrate the intensity over, it should be possible to find focus.
* The below plot shows the same results for a single fiber
* This shows that the width of the line drops in the range of 252-256 mm .
* by fitting a Gaussian function to both the image on the firewire camera and the plots above, the widths could be plotted against the focal length for both.
* Each of these were then fit with a hyperbola function,
* This gave parameters of,
| parameter | FireWire | Fiber |
| mean | 254.8±1.2 | 255.2±1.1 |
| a | 4.28±0.92 | 6.12±1.25 |

Saqib Hussain + Jervis Ong Arrived at 16:24, weather clear
* AA arrived 17:30
* Took example flats with both cameras
* Setup telescope, synched on Vega
* focused the telescope on a star
* took a few dark frames to distinguish dust on the telescope
* Primary observation target identified : rho Cyg- 73 Cyg - HIG 106481, right ascension = 21h 33m 58.85298s, declination = 45° 35′ 29.1 "
* Checked the camera cooler temperatures: -5.2 for ST8 and -15.0 for ST8300
* Took exposures with exposure time 0.1s for ST8300 and 0.5s for ST8
* For ST8300, file names begin with odd alphabets (a,c and so on) whereas for ST8 file names begin with even alphabets
* The data is compiled as below:
| Telescope | Exposure time/s | Time frame/minutes | No.of Images | File starts with |
| ST8300 | 0.1 | 12 | 66 | a |
| ST8 | 0.5 | 12 | 45 | b |
| ST8300 | 0.1 | 16 | 100 | c |
| ST8 | 0.5 | 11 | 45 | d |
| ST8300 | 0.1 | 9 | 45 | e |
| ST8 | 0.5 | | 45 | f |
* Moved on to collate data for atmospheric extinction
* For ST8, we tried to take images with different filters (luminescence, red, green, blue) for an exposure time of 0.4s
* However, due to technical problems we were unable to take images with colour filters
* We continued taking unfiltered images every 10 minutes (as the star moved from the azimuth to the horizon), saving them as files beginning with L
* Exposure time is 0.5s for every image
* Cooling power was within the range of 40 and 49%
* Data are as follows:
| Time | File Name |
| 2158 | L1 |
| 2208 | L2 |
| 2218 | L3 |
| 2228 | L4 |
| 2238 | L5 |
| 2248 | L6 |
| 2258 | L7 |
| 2308 | L8 |
| 2318 | L9 |
| 2328 | L10 |
| 2338 | L11 |
* took a photo of Andromeda
* Turned the coolers off, disconnected the cameras. Double checked everything was disconnected.
* Exported data into USB stick.

set up procedure
* check for damages on solar filters
* solar fillters on finders scope and main scope
* mount camrea
* use a SCT connector
* screw onto fliter and telescop
* RGB filter
* clip onto tube
* C-mount to 1.25 inch tube
* screw onto camera
* camera
* mount camera unto telescope by unscrewing the big ccd camera
* fire wire cable connected to the camera(clips in)
* with them, covered you can open the dome doors
* switch on telescope
things differe form a normal observation:
* use different type of camera( imaging source dmk 21af04.as)
* use a different piece of software
* stop the tracking
IC capture
* open IC capture
* click camear being used
* device properties click off auto gain and exposure
* check if histogram isnt saturated
* adjust exposure so it is not saturated
* saving sequnece of image
* capture -> squence settings
* file name and target, pick a directory(desktop/data/YYYYMMDD) -> index at 1
* file type BMP
* Automated sequence -> interval at 1 sec -> end sequence after 400 Frames
* capture -> sequence timer -> start timer
how to turn off tracking
* set up -> enter
* targets -> enter
* trestral or astonamical ->enter
we are going to be using 2016-11-02 data

time: 17:22 arrived in dome. ENK JT AS AC AA
remove rain cover from telescope
open doors of dome (ropes(tie up), bolts)
go onto roof and observe sky
select Capella(HIP 24608) on Stellarium
RA/Dec 5h17m57.85s / 46deg 00' 40.4''
h(capella) = LST(egham) - \alpha = 1h41m52.8s(egham) - 5h17m57.85s(capella) =-3h36m5.05s
rotate dome to correct direction
callibrate telescope - move telescope manually to point at Capella, it can then know its position on the night sky and be moved using the stellarium programme
first take caps off telescope, turn telescope on(make sure everything is plugged in and switched on,checking all leads and sockets)
telescope automatically moves towards the west)
centre capella in finder scope(scope speed 5)
Synchronise coordinates on Capella ( object -> star -> named -> Capella -> Enter (2 seconds) -> Enter to sync)
move telescope away from capella
use the go-to key to get back to capella
Move to almaaz(HIP 23416) using the hipparcus catalogue method outlined in the script
Use Hip method again to move to Betelgeuse (HIP 27989), and bellatrix (HIP 25336)
open MaxIm DL Pro 5
exposure 1 sec start poor out of focus picture
change exposure to 0.1 sec, X bin 4 continuously taking images
use knobs on scope to unlock mirror and change the focal length, simultaneously slowly moving scope to get the star in the centre of the field of view of the CCD
get star in and out of focus and take picture
calibrate telescope to set on aldebaran
use focus (4 on pad) to get good focus with microfocuser that changes the camera not the mirror
take images in different exposuresmove to fainter section of sky, star cluster near aldebaran cluster 2 shows fringe from coolingtake 10 images to find saturation around 65000 for this CCD
move to 02 Tau and found bleeding and saturation at 10s, took multiple images at different exp times (1x1 binning)
found that simple auto dark callibration was on contiunued with this then took one without this

Weather - cloudy fairly poor visibility
* set up telescope, open dome, take off caps etc
* take picture of blank space, set up guide camera also
* twilight point scope at blank space look at cooling and non cooling effects
* target is betelgeuse, use to focus and synchronise camera
* move scope to pleiades, new target in order to take pictures of cluster, image with multiple stars
* centre on atlas and pleione
* look at error in plate scale as a function of flux ALL FRAMES!!!!!!!!!!!!!!!
* f[0].header this shows all the info about the image and the telescope
* shape(d) Out[40]: (1020, 1530) dx1 = d[0:500,:].sum(0) dx2 = d[501:,:].sum(0) plot(dx1) this will set a range on the x/y axis

time 10:30am arrived in dome. A Cozens, L Lenz D Bedingham S Boogert
poor weather conitions so no solar data could be recorded
used SLR camera to take images of boiler house in order to understand how the manual settings of the camera affect images
took 30 images with different exposure times and varying the ISO number, as ISO increases smaller exposure times are required so not to saturate the image.
The images are located
C:\users\astrodome\desktop\3_data\20171018_Solar
with two files showing the dark frame images taken to show the noise of the camera with the cap on the lens and light brick images taken at different exposure times with different ISO

10:30 dome. Bedingham, Cozens, Lenz
* good weather => took a few images with Canon SLR camera
* The following settings received best results: ISO=100, exposure time=1/4s to 1/8s, max. f-number
* Used rawkit Python package to transform .cr2 files into .tiff
* Applied Hough transformation to find circles in image
* Measured brick width L with ruler and received distance D from dome to boiler house brick via Google Maps
=> L = 22cm, D=104m
* From this calculated angle to be θ = 2*arctan((L/2)/D) = 0.117° = 0.22x(angular separation of sun(0.5°))
* Next steps: - take image of smooth white background to measure the vignetting effect of camera
- adjust parameters of Hough transformation to find correct circle

use DSLR to take white images to look at the natural vignetting effects of the camera, took many exposure times so to get an unsaturated image. Need to process these to get a pixel vs intensity curve to show that the fractional ratio of intensity does not depend on exposure. Also look at different colour channels and create a plot to show all 3
Then set up the telescope so as to record data, fit with sun filters and imaging source camera. Using ICcapture software.
Use shadow of the telescope to align, and adjust further with finder scope.
set telescope to the west of the sun to see it passing through the window, takes around 1min to fully pass no data recorded
Use DSLR to take images of the sun, lowering the exposure times to find an unsaturated image. Use circle finder code to analyse the intensity array across a diameter of the sun.
Attached Text files show the image numbers on the DSLR for varying exposure times ISO=100 for targets of the sun then a white light source evenly lit for investigating the vignetting effect.

10:30 at dome, D. Bedingham, L. Lenz
* cloudy weather => took no images of Sun
* Vignetting images from last week were not symmetric
=> will have to retake those images with diffuse light (outside) and a variety of exposure times to achieve different max/min intensity values,
the ratio of I_max/I_min should be approx the same throughout
Next steps:
* Take correct vignetting images with different exposure times and diffuse light
* Analyse new vignetting images and apply curve fitting to it => V(x) => can receive real intensity with I(x)*V_max/V(x)
* Estimate unscattered intensity f of Sun images
* Fit curve to unscattered intensity => Gaußian fit => should get data back (~Gaußian curve)
* Optimise f

looking into error in blue filter images taken previously
is an error in the programme with the readout, reboots and restarts did not solve this. Updated the verison of IC Capture from 2015 model to 2017, this had some minimal effect
Look at changing the Frames Per Second to a smaller amount (from 30 to 3.75) this did correct for the oscillation problem looking at blue sky
Move to try and take images of sun again with filter
Wait for sun to be away from tree.

Weather Conditions: Clear
Time: 22:40 - 1:50
Targets: Betelgeuse & Pleiades Cluster in RBG filters
Cameras Used: SBIG ST 8XME(camera 1) and SBIG ST-8300M(camera 2)
Both cooled to -20deg
Telescope already synchronised, moved and focused on Betelgeuse. Target too bright for filters. Kept saturating.
Moved to a new target, the star, Bellatrix. Again too bright for filters.
Moved to another new target, HIP26594. 15 images taken for all three filters RBG, exposure time 1.5s.
Then moved to the Pleiades, in narrow view camera (camera 1). We took ten images in each filter with exposure time 10s. And we took ten images in each of the green and blue filters with exposure time 40s.
We switched to camera 2, a wide view that could take an image of the whole cluster. The image is inverted in camera 2. We took 20 images with exposure time 0.4s with no filter.

* set to speed 5, center
* start exposure, bin 4, continuous, center object, speed 3
* adjust focus, unlock primary mirror clockwise 2 revolutions, bracketing process(see how the object is changing), object keeps moving, brightness changes, focus as much as possible, center it again speed 3, synchronize-object,star,named, click for 2 sec
* observede diffraction pattern- something is wrong with the camera, filter plate not moving, adjusting, fixed filter changing
* change exposure time to 0.3s, get star off center, focus on other, dimmer stars, adjust focus once more to see clearly
* discovered diffraction pattern in filter image
* took apart camera with help of Prof Boogert
* once camera filter in working condition, resumed observation
* took exposures of far field stars near Betelgeuse in order to focus the telescope
* shifted focus to plaidees - Atlas and Cleo
* used Astrometry in order to determine our location in the night sky
* once Atlas and Cleo found, took 0.1 interval exposures from 1 to 5 seconds until stars were saturating pixel value
* once pixel values saturated, shifted view to m41 orions nebula
* took one 7 second exposure

15/2/18 Began: 17:30
Started up telescope & opened observatory. Connected to camera with maximdl (disabled camera 2), turned on cooler to -15.
Found Capella @ LST=3:45, h= 22:27, rotated telescope mount. Changed declination to 46 degrees. Located star in viewfinder.
Began continuous 0.1s 4x4 binning image capture of CCD view. Moved telescope (speed 1) opposite to image view due to CCD being upside down, to centre Capella.
Go-to button used, caused telescope to move way off target. Recallibrating as a result. Now LST=4:15, so h = 22:57, relocated Capella. Centered etc.
With LST 4:27, Atlas found at h=0:32. dec 24 deg 6 min.
Used astrometry.net to work out stars from unknown image 1, located area in stellarium
Moved to bright stars (i.e atlas and pleione), checked again with astrometry and stellarium. Synced to Pleione HIP 17851 SAO 76229 on both telescope and stellarium (connected to telescope)
Centred on Pleione. Tested stellarium movement to other stars.
Centred on Atlas, took multiple images at several exposure times, saturating the image individually for both bright stars.
zeroed telescope, closed up dome.
Finished 20:00

Logbook for PH3010 Solar limb darkening mini-project, initial setup meeting
Present: DB, MA, JC, HS
Order of tasks for observation of the sun:
1) DO NOT STARE DIRECTLY AT SUN. DO NOT POINT UNPROTECTED TELESCOPE AT SUN
2) Go outside dome and check that sun will not be obscured by the tree, wind thingy. If it will be, will have to wait before able to take images of sun
3) Check solar filters are not damaged. Fit solar filters to main scope (and if using finder scope, fit solar filter to that). Fit CCTV lens to camera, camera to filters, filters to telescope.
4) Open dome, move opening so that allows shadow of telescope to be seen on dome wall
5) Use the shadow of the top scope (the one secured by two sets of three prongs) to align the telescope with the sun. When the shadows from both sets of prongs overlap, the telescope is (roughly) aligned with the sun
6) If using finder scope, use to target edge of sun.
7) Use IC Capture program to view camera feed (really need to jam the cable into the back of the camera to get the pc to detect it). In device-properties can control gain and exposure settings
8) Use live camera feed to target edge of sun and focus (unlock and use know on back of telescope)
9) Change declination of telescope and monitor live camera feed. Need to find centre-line of sun. This is when any change in declination results in the suns edge moving out of frame (away from centre, only changing declination in one direction will move it out of frame - the other will move it more in frame)
10) On telescope control setup-targets-terrestrial or astronomical
terrestrial will keep telescope at fixed angle, astronomical follows objects through the sky
11) Choose filter to image with. Point telescope as closely as possible to centre of sun and view image histogram. Adjust and exposure until the image is not fully saturating (has a narrow yellow bar - the zero readings - visible) but has as full a range of values as practical.
12) Return telescope to point at edge of sun, in the centre. In IC capture go to the timed capture settings. Choose an appropriate target folder and image capture filenames, set the image type to bmp, turn the 'auto display capture' to off and set an appropriate capture interval and number of captures.
Note: Sun subtends an angle of about 0.5 degrees. Previous years have taken 405 seconds worth of images for this project.
13) capture images. Repeat step 11 onwards for another filter

* Dome entered 10am. Present: MA, JC, HS, supervised by Dr. DB
* Telescope cover removed, solar filters put on
* camera and colour filters were already attached to telescope. setup checked just to be sure
* Telescope setup reviewed+approved by DB
* Dome doors opened, telescope turned on
* Moon was still visible in sky - dome doors moved to allow viewing of it
* Moon used for focus (coarse and fine), took a couple of images of nice craters
* Moon found by (roughly) lining it up with the telescope, then with the finder scope, then with the camera image
* Dome doors moved to allow viewing of sun, telescope slewed to find sun
* telescope shadow aligned on wall behind telescope
* telescope moved to bring the two rows of knobs into alignment (i.e. telescope pointing at sun)
* Using camera feed, approximate equator of sun found at one edge
* Test images taken
* Moon and test sun images stored in focus_images folder
* Colour image sets taken.
* All image sets performed by pointing telescope ahead of suns motion and switching to terrestrial mode - motion of sun across sky then carries sun across the frame of view.
* All image sets taken over 3 minutes 10 seconds. This time determined by timing a test run of the method.
* 1 image per second taken for the length of the image set.
* Used maximum gain for all image sets. Exposure determined by manually slewing across the sun and trialling different exposures. Aim was to get as close to having maximum pixel values in the image, without actually having any maxed out pixels
* Where necessary, solar eclipse glasses were used to directly view sun e.g. to determine if clouds were obstructing the sun, or just the area around it
* Clear Filter 1:
* Gain 799, exposure 1/1000 seconds
* trees obstructing parts of image set - produces obvious errors in dataset
* Clear Filter 2:
* Gain 1023, exposure 1/4000 seconds
* Blue Filter 1
* Gain 1023, exposure 1/154 seconds
* Some obstruction of sun by clouds
* Blue Filter 2
* Gain 1023, exposure 1/154 seconds
* Still some clouds, but far fewer than with Blue Filter 1
* Green Filter 1
* Gain 1023, exposure 1/308 seconds
* Lots of clouds
* Green 2
* Gain 1023, exposure 1/308 seconds
* Even more clouds
* Red 1
* Gain 1023, exposure 1/1241 seconds
* A few false starts (so the file indexing is messed up), but managed to get a good run of images
* Was not able to perform another run with the green filter, due to increasing cloud cover
* Dome doors repositioned above door to roof and closed.
* Solar filter removed and lens cap replaced. Filter stored back in its home.
* Telescope returned to 0h0d
* NOTE: Minor mix-up with imgae file names. All image sets are stored in the appropriate folders / .zips for the colour filter used, but the some image sets use the wrong colour name in the individual image filenames. Recommend handling image sets carefully / renaming appropriately when used.

* Present JC, AD
* Began cooling at 16:45 to -12 deg C (~90%)
* Filter wheel set to Clear, Red, Green, Blue
* Centred on Capella and took GPS-fix. Encountered problem: telescope believed it was -1h RA from Capella however this offset was constant.
* Edit: This seemed to just be an issue with the coordinates read-out on the paddle.
* Centred on M35 and took 1000x0.1s exposures to focus.
* Then took 60s exposure- significant effects of moonlight on image- change target to M36 (RA/DEC: 05 37 13.8/34 09 04)
* Light pollution significantly reduced suggesting moon was indeed the source.
* took 60s and 90s exp in all filters
* moved to (RA/DEC: 05 37 31/34 07 50) and repeated.
* took dark and bias frames before finishing observation at 9:30pm.

Method
- Connect to Stellarium and MaximDL
- Telescope pointed at Vega synced
- Moved to Epsilon Lyrae (epsilon_lyrae)
- Camera disconnected from MaximDL and connected to PHD Guiding
) and saved as *.txt file for further analysis

- 0.2s
- Default Advanced Settings with:
- Full Frame
- RA_PEC_DATA2.TXT
- 0.2s
- Default Advanced Settings but:
- Subframe
- To be added
Test images:

Focus and Filters
Average filter wavelength
- Blue: 450mm
- Green: 550mm
- Red: 650mm
ST-8ME Quantum Efficiency:
- Blue: 55%
- 1.82x exposure from clear
- 60s clear -> 109s
- Green: 70%
- 1.43x exposure from clear
- 60s clear -> 86s
- Red: 75%
- 1.33x exposure from clear
- 60s clear -> 80s
Test Images
M57 - Ring Nebula
M56 - Globular Cluster
- 1x60s Luminance image
M27 - Dumbbell Nebula
- 9x60s Luminance images stacked to form a 6x60s image
- 1x109s Blue image
- 1x86s + 2x60s Green images
- 1x86s + 5x60s Red images
During the Dumbbell Nebula imaging the filters were accidentally changed due to the mouse scroll.
- Possible workarounds:
- Use autosave function to take images
- Check before taking a new single image

APIs:
* [[http://seal.web.cern.ch/seal/documents/minuit/mnusersguide.pdf][Seal Minuit]]
* [[http://iminuit.github.io/iminuit/api.html][iMinuit]]
*Performance (measured with Python %timeit() magic function):*
* PyMinuit: best of 3: 13.9 s per loop
* iMinuit: best of 3: 11 s per loop
*Conclusions:*
* iMinuit is easier to install than PyMinuit
* iMinuit is faster than PyMinuit
* iMinuit have more features than minuit (e.g. export to LaTeX and fake functions)
* Both detected and successfully minimized a 2D Gaussian on all the stars with same parameters
* PyMinuit "accidentely" fitted more Hot Pixels than iMinuit
* PyMinuit includes Simplex and Scan methods, which are not available on iMinuit
* PyMinuit is more stable - annoing bug in latest version cause segfault it limits, steps, ... are not set
Keep PyMinuit for now.

| Created: 10 Sep 2013 16:48:33 | Last Revised: 11 Sep 2013 15:49:16 | Public.PedroPaiva | Building Python on cygwin |
pre-requisite: have [[http://www.cygwin.com/][Cygwin]] installed and a GNU compiler.
Cygwin comes with python pre-installed, from there one can install new packages with:
* easy_install packageName
* pip install packageName
To use ==pip== you must install it first using ==easy_install pip==
The ==pip== method is favorable for it allows you to search, uninstall and upgrade packages easily.
==pip== guide:
* ==pip freeze== - display currently installed packages
* ==pip search packageName==
* ==pip install packageName [--upgrade]== - installs or upgrade an already installed package
* ==pip uninstall packageName== - uninstall a package
*Packages installed*
* ipython
* numpy
* scipy
* pyfits
*To be installed:*
* matplotlib
* opengl
* pyside
* pywin32 (don't support cygwin)
* pyminuit ([[http://code.google.com/p/pyminuit/wiki/HowToInstall][detailed guide]])
1 Download the required files: [[http://code.google.com/p/pyminuit/downloads/detail?name=Minuit-1_7_9-patch1.tar.gz][Minuit-1_7_9]] and [[http://pyminuit.googlecode.com/files/pyminuit-1.2.1.tgz][pyminuit-1.2.1]]
1 Extract and change to Minuit directory (under cygwin)
1 Compile Minuit with:
1 bash configure
make
make install
1 Change to pyminuit directory ( ==cd ../pyminuit-1.2.1== )
1 Build and install with: ==python setup.py install --with-minuit=/location/of/Minuit-1_7_9==

Ring Galaxy (NGC1291)
Protostar (IRAS 20324+4057) "The bizarre looking ring galaxy NGC 1291 in Eridanus.
These fairly rare types of galaxy are usually much fainter objects, but this one at "only" 33 million light years away is easily visible in modest size telescopes though the faint outer ring of material is much fainter than this.
Its strange appearance is the likely the result of a collision with another galaxy in the distant past.
20"CDK with FLI-PL6303e camera. LRGB. L: 70mins. RGB: 5/5/10mins" - Damian Peach
IRAS 20324+4057 is a Protostar in the Cygnus OB2 Association, 4,500 light-years (1,380 parsecs) away.
This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
INT: H-alpha
cyan ACS: F606W (V)

After turning telescope on, it successfully received GPS signal and did not started the usual RA movement.
The Camera was connected to Python via MaximDL
Telescope and Focuser connected to Python via the POTH Hub
Coordinates in agrement between Scope, Python and Stellarium
Target was set to be -0.1º RA from current telescope position and Python SlewToTarget was tested.
Telescope moved the right amount and stopped, both telescope and Python alerted when ready.
A second test was made with +0.5º RA. Also successfully.
Still with small (-0.1º RA/DEC and +0.5º RA) movements, Python SlewToCoordinates was tested successfully.
With the tests done, the telescope was moved to Vega via controled movements on Stellarium
Vega was inside the Camera Range, demonstrating that the Park Method works.
Vega was recentered (-0.01 on RA) and the telescope was manually synced.
During this test, movements as small as 0.003º on RA proved to have no effect whatsoever.
The next step was to test the focuser and the camera.
First, while still on continuous mode of the camera, the Python-Focuser connection was tested.
Python can read the position and move the focuser. Units are steps. 1 step = 20µm
Having confirmed that one can move the focuser with Python, Vega was taken out of focus to test if we could focus the star using a small

prin = True

POTHFocuser.Move(step)
while POTHFocuser.IsMoving:
if not prin:

*Focus movements*
* Positive -> In
* Negative -> Out
*Tests*
The data below have a significant experimental error associated with the not fixed measuring equipment.
Also, they can have errors related to a possible angle between the measuring equipment and the in-out axis therefore, the real value would differ by a factor of cos(theta)
*out*
* move(-5000) - 1.86mm
* move(-5000) - 1.80mm
* move(-5000) - 1.86mm
* move(-5000) - 1.81mm
* move(-5000) - 1.88mm
* *mean = (1.842 ± 0.031)mm*
* move(-1000) - 0.31mm
* move(-1000) - 0.40mm
* move(-1000) - 0.44mm
* move(-1000) - 0.27mm
* move(-1000) - 0.45mm
* *mean = (0.378 ± 0.076)mm*
The out movement is coherent and 5000 steps is indeed equivalent to 5x1000 steps
This give 1 step aprox 0.37µm
*in*
* move(5000) - 1.52mm
* move(5000) - 1.55mm
* move(5000) - 1.52mm
* move(5000) - 1.48mm
* move(5000) - 1.57mm
* *mean = (1.528 ± 0.031)mm*
* move(1000) - 0.21mm
* move(1000) - 0.20mm
* move(1000) - 0.15mm
* move(1000) - 0.30mm
* move(1000) - 0.18mm
* *mean = (0.208 ± 0.050)mm*
The in movement is 25 to 50% smaller than the out movement (depending on the movement size) with larger movements closer to the equivalent out.
This give 1 step being between 0.2 and 0.3µm
*Conclusions*
The execution of the above movements led to the following conclusions:
* Focuser always finishes in a 'in-movement' (e.g. asking to move out will make the focuser goes more than needed and come back about 1mm)
* This causes the isMoving check to return before the focus being ready.
* Focuser limit less than aprox 30k steps when going in.
* When close to the limit, focuser will overstep (move(5000) caused the focuser to move 2.76mm)
* Focuser isn't ready when isMoving returns False.
* There's a time gap when a second comand will be accepted but not executed.

[[http://www.newastro.com/book_new/ebook/c2d.pdf][Diffraction aids]]
---------+++ Using a Bahtinov mask to find the focus:
Based on Laurie's idea and [[http://starryvistas.net/articles/focusmask/focusmask.aspx][this article]] a set of 144 images were taken.
3 images for each of the 48 moves made by the focuser. All the movements were 'in' moves of 250 steps.
The images had a 5s exposure time and a master dark (made of 10 dark) was made and reduced from the images.
On each image, a gaussian was fitted to the brightest star (142/144 success) and the amplitude and sigma median were taken for each set of 3 images per focuser position.
The data was then plotted and assumed to be in a quadratic form. The results can be seen on the images below.
For the Sigma X values, the minimum can be found at: 4841 steps
While Sigma Y minimum is at: 5411 steps
And the Amplitude maximum at: 6804 steps
According to [[LogBookAstronomyEntry0015]], the 2000 step (aprox 600µm) difference would be more than double the depth of field for the telescope [[http://starizona.com/acb/ccd/advtheoryfoc.aspx][(287µm on a f/10)]].
A visual analysis of the graphs would suggest a minimum and a maximum for Sigma Y and the Amplitude close to 6000 steps and, visually, the image at step 5750 (image set 23) is the sharpest presenting a nice 'X' diffraction pattern produced by the Bahtinov mask.

* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* Attempted Installation of Python Canopy on personal laptop to begin data analysis but fails to install on Windows 8.0 (Attempting update to 8.1 to see if it rectifies issue) [Installed 32 bit version instead]
* Set temperature value to -07.5 deg C, left for 30 - 40 mins to stabalise.
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* For data analysis will need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.

Using Autosave feature to speed up process, Hence file format has changed to: T-10.0-001-E0001
Must go back to data taken on the 18/10/2013 and rename files for consistancy -> Done.
Proceeded to take another 120 dark frames at -7.5 degrees, as with coolers on 100% sensor temp would not go below -10.6 degrees.
Proceeded to take anothe 120 dark frames at -2.5 degrees.
CCD will then be reset to 0 degrees, and frames will be taken every 30 seconds as it is cooled from 0 to -10 degrees. The exposure time will be 2 seconds. Due to lack of time this will be postponed until next week.

---------+ Project meeting on 24 / 10 /2013
Present: Chris Haynes, Paul Hallam, Ryan Cheale, Dr Boogert, Professor Cowan.
Continued discussion on taking and analysis of dark frames.
Due to the dome not being cold enough during the day, it is difficult to cool the camera down to -15 or -20 celcius. Therefore, the remaining readings will be taken further into winter, when the dome is colder.
Objectives for analysis of dark frames:
* Plot a histogram of the -5°C, 60 second frame and compute the mean, median and standard deviation.
* Plot the column mean and consider the standard deviation for all columns.
* Plot the standard deviation as the square root of the mean and check to see if it's a Poisson Distribution.
Additionally, we should think about the dark current rate (the rate at which an electric current is generated in the chip due to the production of electrons and holes) and how to compensate for it.
We should also consider what the faintest star we could detect would be, looking at the point spread function of our telescope.

---------+++ Activity Log
* Took off cover for telescope & Camera
* Turned on Camera and followed steps detailed [[Students.UnderGraduates.RyanChealeCameraTechnicalAspects][here]]
* Set temperature to -10 deg C, waited 30 - 40 mins for stable temperature
* Used Autosave Sequence located at 'Desktop/Data/20131016_RC/25darks60s.seq'
* Autosave feature allows running of each permutation whilst saving automatically
* Format T-tt.t - NNN - Eeeee.fit where T - temperature, t - temperature value, N - repetition (==20) , E - Exposure, e- Exposure time value (0.1s, 1s, 5s, 10s, 60s, 180s)
* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* turned off the coolers on the camera to allow it to reutn to room temperature.
* Proceeded to take data in 30s intervals for 30mins whilst turning the coolers back on and allowing the temperature to reduce to -10 deg C to see what effects allowing the temperature to stabalise has
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* For data analysis still need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.
Python
* Began the use of the canopy environment to begin data analysis in Python.
* Running into multiple problems with the canopy environment with plotting graphs
* Have made plots for the mean, standard deviation, max and min values of the data set T-05.0-NNN-E0600
* Struggling to create histogram plots, either the kernal or the environment tends to crash when trying to create a histogram of a single fit file
* Next steps:
* Produce median plots
* Refine code so only needs slight input alteration for other data sets
* Produce histograms and then further plots based off of the histograms
* begin analysis on cool down data.

A study into the variation of background pixel count with temperature.
Initial CCD temperature was recorded to be 18 degrees. Coolers were turned on and CCD cooled to 0 degrees over the course of an hour, to ensure the entirety of the CCD began at zero degrees for the following study.
Coolers were then set to cool the CCD to -10 degrees, and one second exposures were to be taken every 30 seconds for one hour over this cool down period.
The data shall be saved in the following format: Cooler_Study-001E001
Also this shall also provide 29s exposures between the 1s exposures, which shall appear like this: Cooler_Study-001E029. This data will not be analysed.
When this collection of data has been finished, CCD was at a constant -10 degrees. The CCD coolers were switched off, and the CCD warmed back up to room temperature. Using the same method, one second exposures was taken every 30 seconds for one hour over this period.
The data shall be saved in the following format: Cooler_Study_2-001E001
Again this will also produce data that will not be analysed, in the form of: Cooler_Study_2-001E029
Room temperature in this case is 25.6 degrees.

---------+++ Telescope Set Up
* Target Delta Cephei selected using Stellarium and AAVSO catalogs
* Open shutters (ropes, pull apart, tie off ropes, motor control
* Turn power on
* Press power switch on telescope
* Removelens caps
* Point towards Vega
* Line up with finer scope
* Take continuous frames 0.1s
* Center Vega in frame
* Synchronise Vega with Maxim DL and Stellarium
---------+++ Target Information
* Pulsating Variable star, magnitude variation 3.5 - 4.4, Δm = 0.9
* Period 5.4 days
* Next maximum, 07/12/2013, 9:32
* RA: 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From simulated light curve - expected Δm(max) = 0.26, expected Δm(min) = 0.01
* From light curve of Delta Cephei, and time of next maximum, we believe the magnitude should be decreasing
* Companion star HIP 110988 used as a reference star
---------+++ Initial Observation of Delta Cephei
* Centered on Delta Cephei - did not use Stellarium as could move telescope through the pole
* Frames were taken using different filters, initial exposure times:
* No filters - 1s
* Blue filter - 10s
* Green filter - 3s
* Red filter - 3s
* Took sample frames using this-set up, max pixel count was found using Python
* Re-evaluate exposure time to ensure max pixel count was in the range 55000 - 60000
* Re-evaluated exposure times:
* Focus filter - 1.1s
* No filter - 1s
* Blue filter - 10s
* Green filter - 5.1s
* Red filter - 3.3s
* Decided to take 5 repeats for each of these, and 10 repeats for Dark and Bias frames
* Autosave feature was used to take a sample set of data
* Residual image of Star found on Dark frames - low pixel count
* Implemented a 'Trash' frame before the Dark frame to attempt to remove this -> some residual image still remained
---------+++ Observation of Delta Cephei
* Autosave feature took approximately 10 - 15 minutes to run
* Approximately three runs were taken per hour
* Delta Cephei was observed for 5 - 6 hours
---------+++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope
* Turn off camera
* Turn off telescope
* Put cover back on camera
* Close dome shutters
* Turn off PC monitors
* Turn off lights and leave dome

20140213 LN
Reasonably clear and forecast to be good. Worth a try to get some practice in.
* CCD at -15oC
* Aligned to capella - very high in sky.
* Went down from 46 to 37 DE to theta_aur as capella saturates the camera.
* Take subframes to practice focussing. Recorded 400 frames of theat_aur for analysis later. SNR is good as super bright. Peak around 30000 ADU. Jumps around A LOT so will have to align by centroid. Then can have a look at PSF.
* Exposure 0.1s
* 300 exposures recorded in 10m12s
* 400 exposures recorded in 13m37s *Sat bhatinov mask carefully on front of scope. Recorded 50 images with same setup as before. Not so clear.
* Exposure 0.5s
* Not so clear. Pattern seems very small indeed on CCD compared to internet images. Collimation is definitely poor and its windy so don't expect it to be great. Anyway, reasonably good in focus.
* Having a look at the Pleiades. Too extended to see anything nice and certainly with the seeing. The stars are very bright and the nebulosity not so, so quite hard to observe under these conditions.
* Imaged Andromeda ok. 30s exposures.

Using the spectrometer to find the brightest spectral line in mercury and Find the best micrometer reading for the angle of the camera.
Camera was ST-7E, Setup SBIG Universal.
Temperature for all the images was -6.5 deg C.
*Focus*
Exposure time: 0.1s; Grating distance 1.814mm; Camera angle micrometer reading 2.495 (heavily sloped)
Used continuous range to find a reasonable staring point.
Used range of 18mm to 20.5 mm in steps of 0.5
Reduced range to 19mm to 20.5mm in steps of 0.10
Reduced range further to 19.50mm to 19.80mm in steps of 0.05
*Camera Angle*
Exposure time: 0.1s; Grating distance 1.814mm; Focus distance was 19.60mm for this
Used continuous range to find staring point.
Used range of 2.50mm to 5.50mm in increments of 0.5mm to start.
Reduced range to 4.00mm to 5.00mm in steps of 0.10mm
Reduced range further to 4.45mm to 4.65mm in steps of 0.05mm
Found the best angle to be _4.60mm_
*Brightest Peak Data*
Looking through the spectrum the brightest peak, found at 4.00mm in grating micrometer.
This was saturated so the lamp was moved back by 5cm which was still saturated, then we moved it back by another 5cm which put the lamp back from the optical fibre by 25cm. This reduced saturation where refocus was done. Seemed to saturate at 50,000 confirming it was brightest peak.
Used this to check the focus and recalculate.
used a range from 19.50mm to 20.50mm in steps of 0.10mm
Found best focus distance on micrometer to be _20.10mm_

27th Oct 2014 Msc Observation.
*Begun:* 18:30
*Finished:* 22:30
Conditions: Mostly clear, a little muggy. No cloud coverage.
Begun observation session with a run down of the procedure to prepare the dome.
*Dome Procedure:*
-
Enter dome
- Close the hatch to prevent heat rising and entering the dome. The floors beneath are heated which causes a ‘chimney’ like effect if the hatch is left open as the hot air from below will rise up through it. Ideally the scope and dome should remain cool so noise due to thermal fluctuations is kept to a minimum.
- In the Maxim DL suiteconnect to the telescope. This allows control of the camera for example you can set exposure times and capture images from the program.
- Enable the CCD cooler in Maxim. This should be done ~1 hour before taking exposures. If you take observations too soon after enabling the cooler you get a ring like effect on your observations around the outer area of the frame. The ring progresses further to the sides of the frame as the CCD cools until it eventually disappears.The set-point of the cooler is set to -10 degrees celcius and the CCD itself fluctuated around this point slightly once the cooler had taken full effect.
- Untie the ropes that control the shutter of the dome. Pull on ropes to open the shutter of dome, if the shutters do not open with ease, there is a long stick with a metal prod at one end which can be used to manually push the shutters open from near the top of the dome.
- Once shutter is open, tie the ropes off again to make sure that they are kept out the way of the moving parts of the done which can rotate bothe counter and clock-wise
- Using the door on side of dome, go outside and do some preliminary naked eye observations to find an interesting object to observe (this is important for aligning the telescope as detailed later on). This allows you to plan roughly where the telescope and open shutter should be pointing to allow unrestricted viewing.
- Using the dome control unit, align the dome opening with what you want to observe.
- When finished observing, realign both the dome and telescope to their origional position. Close the dome shutters and tie up the ropes.
To begin making observations you need to align the telescope to a bright object in the sky and then enable tracking. Tracking corrects the position of the telescope relative to the sedereal motion of the stars. This is necessary because the field of view of the telescope is so narrow if it was left stationary, the object you are observing will move out of frame. To align the telescope, the first step is to identify a bright object visible to the naked eye in the nights sky. You can acess the roof from the dome via. the door on the side. Once on the roof you are able to evaluate potential targets. We identified the star Vega (25ly away, 2.1M0, alpha lyrae - the brightest star in the lyra constellation and 5th brighest in the night's sky). The star charts provided in the program stellarium coupled with manual positional measurements allow you to identify the star you are looking at with the naked eye.
Once a object in the sky has been chosen, the next step is to align the telescope to enable the activation of tracking.
- *Telescope Alignment:*
-
Use a high speed on the control paddle (speed button -> 9 is fastest, 1 is slowest on number pad) to crudely align the scope with what you want to observe using the arrow buttons. This can be done roughly by eye by lining up the two bolts on the side of the telescope with what you are looking for.
- Then use the viewfinder which has a set of crosshairs to align the scope more accurately with the object in the sky. A medium speed setting on the paddle can be used to move the scope with a greater deal of precision.
- Once the crosshairs are centred on the object you wish to view, take an exposure in the maxim DL suite. Once the image has been taken and downloaded you can adjust the scope to get the object centred in the frame. If you set maxim DL to take continuous ~1s exposures you can get a better sense of the best way to align scope and object.
- Once the scope is aligned, enable GPS lock. This continuously corrects the scope to account for the rotation of the earth. The field of view of the scope is very narrow causing the object you are observing to move through the frame if the scope remains stationary.
- Once tracking is enabled, the scope should keep the object you are trying to view in frame automatically.
- Using the control paddle, tell the telescope which star/object it is currently aligned to
- With the telescope connected to stellarium which now allows you to control the scope through the program itself. Using the star charts, you can align the scope to stars/objects shown in stelarrium. (Wait for the ‘beep’ if you move the scope in the program. The scope moves quickly at first but then makes finer corrections to ensure the scope is aligned well. The 'beep' occurs once the telescope is properly aligned, it can take some time ~20-30 secs).
- While repositioning the telescope it is important to be aware of it's orientation with respect to it's base. The telescope is capable of flipping over on itself which can cause the CCD attatchment to collide with the stand. In a situation where this may happen, power down the telescope via the power controls located on its stand immediately.
With the telescope aligned you can control where it is looking via. the stellarium program. Multiple exposures of Vega were taken at different exposure lengths using the Maxim DL program.
Using stellarium, the telescope was then trained on the open cluster M-39 in the constellation cyganus (800ly away from earth). Again took multiple exposures. The cluster is composed of a number of stars. Using the star chart in stellarrium the star patterns were compared to that shown in the exposure allowing for individual identification of the stars the cluster is made up of.
You have the ability to manually focus the telescope. If it is out of focus the exposures of stars can present as donuts (dark centres with bright outer ring) or they seem flat and blurred at it's edges. The procedue to manually focus the telescope is first to 'unlock' the mechanism. There are two dials, the shorter one can be rotated to unlock the device allowing the second longer dial to be turned focusing the telescope.
Last target of the night was the andromeda galaxy known as M-31 (as it is a messier object) and is 2.5x106 ly away from earth and the closest spiral galaxy to the milky way group. This galaxy has a mass ~ 1.5x10^12 M0. 10 exposures were taken one after the other with the intention of eventually using them to form 1 image with considerably less noise.
An interesting point to note is that movement of the atmosphere above the telescope can cause exposures to shift in and out of focus. This was made evident as during continuous exposures of M-39, the stars were alternating between being in focus and out of focus.
The exposures taken during the night of observation are attached to this post.

*Observations of the Spectrum of Betelgeuse*
Started looking at Capella. Using a small sheet of tracing paper to allign the star in the optic fibre coupling. With Capella at a high Altitude we switched to Betelgeuse as a target to make allignment easier.
Viewed Capella at
5hrs 20' 30'' RA
45deg 8' 2'' DEC
with the micrometer at Grating-4mm, Angle-3.25mm, Focus 20.2mm.
changed the RA 5'' either side to align it centrally while observing the intensity recieved.
*Betelgeuse*
Next look at Betelgeuse,
5hrs 58' 32' RA
6deg 25' 30'' DEC
Took a 30s exposure at 4mm to look at the spectrum as best as possible. Then took 60s exposures of Betelgeuse between 0mm and 10mm in steps of 0.5mm.
After Betelgeuse we briefly moved to the Orion nebula however it was too dim to observe.
*Pollux*
7hrs 46' 14'' RA
27deg 59' 18'' DEC
Again took 60s exposures from 0mm on the grating position micrometer too 10mm in steps of 0.5mm.
Laurie left at 23:00
*Castor*
7hrs 35' 22'' RA

Please edit and put your text etc. here
Start Time: 19:00
Conditions: Slightly cloudy at start, quickly became clear around 8pm and remained clear.
Observations:
*Castor (Alpha Gem)*
Aligned to Castor, RA: 7h 34m 35.87s, Dec: 31dg 53' 17.82" Apparent Mag: 1.93
Ring visible due to cooling of CCD chip taking place.
*Near Castor*
Observed multiple stars near Castor with low magnitude (10 - 15)
No images taken.
Ring still visible.
*NGC2388*
Centred on galaxy NGC2388, Apparent Mag: 14.
NGC2388 was chosen as a target as it is known to currently contain a Supernaova of Apparent Magnitude 15. See http://www.rochesterastronomy.org/snimages/snactive.html
Supernovae: PSN J07285387+3349106, RA: 07:28:53.87, Dec: +33:49:10.6, z = 0.013790
One frame was taken at 120s exposure. Stars were cross checked with Stellarium and were found to be low magnitude (10-16). Two other galaxies were also clearly visible, NGC2385 and NGC2389. The cooling ring was still visible at the edges of the frame. This location was chosen for the target of this observation due to the number of low magnitude stars, and the presence of three galaxies.
Uploaded a frame to astrometry.net
Experimented with 180s exposure, decided to use 120s.
Stacked frames using MaximDL built in image stacker to invstigate noise reduction.
Images taken:
Data was taken in bursts of 9 images, 3 Light Frames with 120s exposure, 3 Dark Frames at 120s exposure and 3 Bias frames.
Dome was realigned every 2 bursts to ensure unobstructed view of the sky.

---------+ 2015 05 20 LN DSLR Observation
* Trying out DSLR on back of scope
* Benefit - easy live video to investigate focussing, wide field of view
---------++ 20:30 start
* Dismounted SBIG camera (in case)
* Canon DSLR bayonet adapter + BADER 2" - T/2 Nosepiece on back of micro-focuser
* Observed Moon, Venus & Jupiter during twilight ~ 21:40
* Aligned & synchronised to artturus star to the south as visible to the naked eye
* image of M3 globular cluster ~ magnitude 6 - can make out ok in photos but still blue sky background as still slightly light
* 2155
* Trial of Deep sky object - still lightish but will keep iterating over objects
* Bodes Nebula mag 6.9
* Of note is that the DSLR is slim enough for a polar flip of the mount. Haven't, but can.
* Whirlpool Galaxy
* Getting better images but can only really see core of galaxy - still to much sky glow
From images of a single bright star or say of Jupiter and it's moons, you can see what appears to be both coma and chromatic aberration. The edges of non-point like objects have an orange tinge on one side and a blueish tinge on the other. Jupiter is relatively low just now so there is a strong affect from the atmosphere / imaging but still Jupiter had an asymmetric tinge. The moons were also quite distorted. Although the 'live view' gives you some indication, it simulates the exposure settings and can distort the image a little. Best to take images directly and zoom in to compare. Not too different from live view though.
* Telescope likely needs collimation, but the trouble is finding a good enough night for to be able to observe any improvement.
Sky much darker now. While no clouds around, there is a bit of haze - can't see huge multitude of stars.
* Starting at 3845 images of great cluster in hercules.
Finish at 22:20

---------++ *Before taking data*
* Time of turn on: 18.20.
* Cooler set to -7 degrees.
* Temp at -6.9 degrees at 18.30.
* Center the telescope on Vega.
* Aling the telescope to Vega. (~Mode on the controller)
* Speed 5 and later 3 on controller while focusing on Vega.
* Microfocuser used to fine focus.
* Speed 3 to place Vega in the center of the image.
---------+++ Alpha Persei Cluster (Cr 39, Mel 20)
* We chose our cluster as the Alpha Persei cluster.
* To focus on the cluster we chose a nearby bright star Mirphak.
* We used it to correct our ofocusing and we synched Stellarium wityh the telescope.
* We choice a patch of the cluster (HIP16001) and took 10 vimages of 10 second exposures. ( x binning set to 1, x anmd y originally inverted, this was reversed)
* 5 bias frames and dark frames of 5 1min exposure.
* Took 3 40 s red.
* Took 3 40-s gtreen.
* Took 3 90 s blue.
*
* Move to a different patch (around RA:3h29min29s, DEC:49deg44'16")
* Ian joined us at 20:00
* 3 images of 60s visual.
* 3 images of 120s red.
* 3 images of 120s green.
* Finished taking data at 8.30 pm.
---------+++ Dark and bias frames
* Started taking dark frames. 5 images of 120s.
* Take 10 bias aswell.
Observation finished at 8.56pm.

The aim of the session was to modify the parameters of the camera. Using only OpenCv it was impossible to set the camera's parameters with known units.
py-ic-imaging-control was downloaded from: https://github.com/morefigs/py-ic-imaging-control
py-ic-imaging-control is a python wrapper for the IC imaging control software development kit from the imaging source (TIS). It provides control to TIS cameras, and can serve as an alternative to using OpenCv to access the cameras parameters.

The DMK camera was fixed to a tripod and pointed at the moon.
Run1: Gain set to 180 and images were recorded of the moon at a frame rate of 7.5 frames per second. The algorithm left the exposure setting on 1 as the image was not over or under exposed on this setting.
Run2: Gain was increased to 1023. The images were over exposed and the algorithm accounted for this by changing the exposure setting in increments of 1. It was noted that this was very slow to respond to large and sudden changes in conditions.
Run3: The code was modified such that the amount the algorithm changed the exposure setting depended on the number of pixels that were saturated. This massively decreased the time the algorithm took to find the correct exposure setting. See screen shot.
Images were also taken of Orion's Nebula, see image file names for parameter settings.

Az/Alt: 318deg 44'20''/38deg34'50''
Took testing pictures: Cooling_1 and cooling_2, can be seen a ring surrounded by the ice. Secong image shows larger ring, meaning hte camera is cooling down
Cooling_3 image is clear and even
Checked the wether with met office, clouds are exopected to clear for the rest of the night
Finding the star by eye, alighning the tescope, using stllarium found it was Procyon
As it wasn't clear that the star is Procyon, checked with Rigel
Took images of the delta cep with no filter and with filters: red, green, blue and spectroscope. Aimed for 50 000 pixel value - the closest to the maximum possible p.v.
Exposure time was increased as different filters were applied, because different filters obsurb more light.
Cloudy weather led to taking many pictures for blue filter with longer exp time, 16 sec.

Please edit and put your text etc. here
---------+ Finding focus of optical fibre
* The focus of the optical fibre was found by taking a relative distance between the lens and the position of the optical fibre, and measuring the amplitude of a spectral line from the laser found at 3.5mm.
* taken at 1mm intervals between 230m and 270mm.
* Fit with hyperbolae as approximation
* distance measured with ruler so very approximate i.e ±1mm
* Best focus was found at 250mm±2mm
* Iris was almost closed as the laser would saturate camera at shortest exposure.
* also took more data as SBIG ST-7E was cooling.
* Just need extra part to connect firewire camera, so that the alignment can be competed.

Please edit and put your text etc. here
---------+ Focussing Beam Splitter
* To find best focus should be able to focus onto a single fibre, once one illuminated, in focus. will have to use extension rings for optical fibre.
* CCD camera can then be adjusted until in focus.
* Focus by shifting backwards and forwards on rails.
* Find focus of camera with max intensity and minimum width of laser.
* Use diffuser or neutral density filter, will need neutral density filter.
* Make two plots of intensity on camera and fiber and adjust until peaks overlap.
* Such that there are two plots which look similar to:
---------+ Aligning Beam Splitter
* Align by moving the mirror horizontally and vertically until maximum intensity
* possibly get 3 more irises, to control aperture at camera, fibre and entry, to make sure always have good alignment.
* As now in focus, can scan around fibres and find the relative positions compared to the end where they are arranged into line.
* This could help with finding best position of ray on camera
* Look up mirror and see how much change in angle before lost fibre, one full turn until laser out of view.
* try to get two irises as far away from each other for best alignment.
* once part for CCD arrives, move around and find relative positions on camera to positions on optical fibre.
---------+ Relating to telescope
* Have to use larger beam size so that f# is the same as the telescope, f# = 10,
* currently 3 dioptre lens, so 1/3 m focal length, this means need a beam diameter of 33.3 mm or a longer focal length.
* as , where f is the focal length, d is the diameter of beam or aperture and f# is the f number.
* consider which camera to be used.
* beam splitter reflects 30% and transmits 70% so check this.
---------+ testing intensity
* tested the intensity at reflection and transmission, with diffuser and tissue in front of laser, tissue made intensity vary substantially so averaged over five frames, the reflection intensity was found to be 3% of the transmission intensity, however there could be problems with focus and alignment at the refection, need better analysis of this.

---------+ Aligning Camera and optical fiber
* Spectrum images,
* Exposure: 0.1s
* Temp: 10 deg
* used subframes around spectral to speed up
* FireWire camera * Exposure: 1/500 s
* The FireWire camera was attached to the beam splitter and connected to IC capture
* Optical fiber was attached using a spacer to approximate the same focal length as the FireWire CCD
* Initially an approximate focus was found on the FireWire camera.
* Then the angle of the mirror was adjusted vertically such that the laser beam was scanned vertically.
* images of the position on the CCD and the spectrum were taken at a range of positions.
* The amplitude of the spectral line was then recorded with position on the CCD.
* This gave a plot shown below for the maximum intensity. i.e centre of fiber
*
* This was then repeated for a scan horizontally, which gave the plot below.
* The best positions were found to be at [190,218] pixels, i.e 190 pixels across and 218 pixels down
* The the focus of the image was to be found.
* The box which the beam splitter and camera is attached to was placed on the rails and scanned backwards and forwards using a ruler for approximate focal length.
* Images were recorded for both the camera and optical fiber, and the amplitudes were plotted against focal length.

Please edit and put your text etc. here
---------+ Alignment of Camera and Optical Fiber
* SBIG camera,
* Temp: 10deg
* Exposure: 0.1s
* subframe around fibers
* FireWire Camera,
* Exposure: 1/500 s
* Took focus measurements first by moving beam splitter to find best focus.
* Best focus was found by subtraction background of spectral line image and summing pixels
* Best focus for image was found by finding max pixel value
*
* The optical fiber focussed ~6mm from the FireWire camera
* Optical fiber was adjusted such that it is as far out as possible using the smallest spacer, and the camera was adjusted so that it was as close to the beam splitter as possible.
* This was to close the 6mm gap found earlier
* The fiber and camera were then realigned as the FireWire camera will have been rotated slightly and moved out of alignment.
* Both horizontal and vertical alignment were used and the best positions were found at maximum intensity the same as for the focus.
*
---------+ Attachment of guidescope
* Two mounts for the dovetail plates attached on the top of telescope, plate then attached.
* The two dovetail plate mounts for the bottom of the telescope have to have small section removed due to bolts on the telescope which were in the way.
* Bottom dovetail plate then attached.
* guidescope rings and guidescope attached to the top plate
* counterweight attached to bottom.
* The telescope was then approximately balanced by adjusting the counterweights position on the plate and by unscrewing the counterweights so they were further from the OTA.

Please edit and put your text etc. here
---------+ Alignment of fiber horizontally and vertically
* SBIG camera for spectrometer:
* Exposure: 0.1s
* Temp: 10 deg
* Subframes
* FireWire Camera:
* records video at 30fps
* Exposure: 1/500 s
* Approximate focus was first found. set at 255 mm
* The mirror was adjusted horizontally such that the laser moved horizontally in the camera frame.
* Images were then taken of both the spectral line of the laser and the image on the FireWire camera as it was scanned, 40 images were taken.
* The maximum intensity of the beam and its position were recorded on the FireWire camera and the summed intensity was recorded for the spectrum with removal of backgorund.
* The intensity on the spectral line was then plotted against the position on the FireWire camera, this gave a plot shown below.
* The peak position on the above plot is then used to set the position of the beam on the camera, which is approximately at a position of 200 pixels.
* Once the position has been set the process was repeated scanning this time vertically, this gave a plot as shown below.
* The best position for the beam to be on the camera for max intensity at this stage is then at pixel values [200,216].
---------+ Focussing the beam
* Once the beam has been set to the best position as found earlier the camera and optical fiber were adjusted between distances of 220mm-290mm in 2mm intervals to find the best focus.
* Here the same measurements as before were made. The intensity of the spectral line and the maximum intensity of the FireWire camera are plotted against focal distance.
* The plot of both the camera and optical fiber is shown below.
* With this image the approximate best focus was set at 250mm
---------+ Repeat of alignment
* The alignment process was then repeated as before, this gave the below plots.
* These gave maxima at a pixel position of [201,217], The image below shows the position of the laser of the camera at this point:
---------+ Horizontal Scans at different Focal lengths
* For 6 different focal lengths, 240,244,248,252,256,260, a horizontal scan of the laser was recored on the camera and the spectrometer. This range was chosen as in the above focus plots, this is where the intensity flattens.
* For each of these the position of the laser of the FireWire camera was plotted against the total intensity of the fibers.
* The aim was that the focal length which gives the smallest width of a spectral line is the correct focus.
* The plot below shows the intensity plot for each of the focal lengths, and the widths of the line.
* This shows the widths does not change much in that range, this could be due to the fact that the focus is smaller than the size of the optical fiber, therefore, the integrated amplitude will remain the same in this range.
* Therefore, by selecting a single fiber to integrate the intensity over, it should be possible to find focus.
* The below plot shows the same results for a single fiber
* This shows that the width of the line drops in the range of 252-256 mm .
* by fitting a Gaussian function to both the image on the firewire camera and the plots above, the widths could be plotted against the focal length for both.
* Each of these were then fit with a hyperbola function,
* This gave parameters of,
| parameter | FireWire | Fiber |
| mean | 254.8±1.2 | 255.2±1.1 |
| a | 4.28±0.92 | 6.12±1.25 |

Saqib Hussain + Jervis Ong Arrived at 16:24, weather clear
* AA arrived 17:30
* Took example flats with both cameras
* Setup telescope, synched on Vega
* focused the telescope on a star
* took a few dark frames to distinguish dust on the telescope
* Primary observation target identified : rho Cyg- 73 Cyg - HIG 106481, right ascension = 21h 33m 58.85298s, declination = 45° 35′ 29.1 "
* Checked the camera cooler temperatures: -5.2 for ST8 and -15.0 for ST8300
* Took exposures with exposure time 0.1s for ST8300 and 0.5s for ST8
* For ST8300, file names begin with odd alphabets (a,c and so on) whereas for ST8 file names begin with even alphabets
* The data is compiled as below:
| Telescope | Exposure time/s | Time frame/minutes | No.of Images | File starts with |
| ST8300 | 0.1 | 12 | 66 | a |
| ST8 | 0.5 | 12 | 45 | b |
| ST8300 | 0.1 | 16 | 100 | c |
| ST8 | 0.5 | 11 | 45 | d |
| ST8300 | 0.1 | 9 | 45 | e |
| ST8 | 0.5 | | 45 | f |
* Moved on to collate data for atmospheric extinction
* For ST8, we tried to take images with different filters (luminescence, red, green, blue) for an exposure time of 0.4s
* However, due to technical problems we were unable to take images with colour filters
* We continued taking unfiltered images every 10 minutes (as the star moved from the azimuth to the horizon), saving them as files beginning with L
* Exposure time is 0.5s for every image
* Cooling power was within the range of 40 and 49%
* Data are as follows:
| Time | File Name |
| 2158 | L1 |
| 2208 | L2 |
| 2218 | L3 |
| 2228 | L4 |
| 2238 | L5 |
| 2248 | L6 |
| 2258 | L7 |
| 2308 | L8 |
| 2318 | L9 |
| 2328 | L10 |
| 2338 | L11 |
* took a photo of Andromeda
* Turned the coolers off, disconnected the cameras. Double checked everything was disconnected.
* Exported data into USB stick.

set up procedure
* check for damages on solar filters
* solar fillters on finders scope and main scope
* mount camrea
* use a SCT connector
* screw onto fliter and telescop
* RGB filter
* clip onto tube
* C-mount to 1.25 inch tube
* screw onto camera
* camera
* mount camera unto telescope by unscrewing the big ccd camera
* fire wire cable connected to the camera(clips in)
* with them, covered you can open the dome doors
* switch on telescope
things differe form a normal observation:
* use different type of camera( imaging source dmk 21af04.as)
* use a different piece of software
* stop the tracking
IC capture
* open IC capture
* click camear being used
* device properties click off auto gain and exposure
* check if histogram isnt saturated
* adjust exposure so it is not saturated
* saving sequnece of image
* capture -> squence settings
* file name and target, pick a directory(desktop/data/YYYYMMDD) -> index at 1
* file type BMP
* Automated sequence -> interval at 1 sec -> end sequence after 400 Frames
* capture -> sequence timer -> start timer
how to turn off tracking
* set up -> enter
* targets -> enter
* trestral or astonamical ->enter
we are going to be using 2016-11-02 data

time: 17:22 arrived in dome. ENK JT AS AC AA
remove rain cover from telescope
open doors of dome (ropes(tie up), bolts)
go onto roof and observe sky
select Capella(HIP 24608) on Stellarium
RA/Dec 5h17m57.85s / 46deg 00' 40.4''
h(capella) = LST(egham) - \alpha = 1h41m52.8s(egham) - 5h17m57.85s(capella) =-3h36m5.05s
rotate dome to correct direction
callibrate telescope - move telescope manually to point at Capella, it can then know its position on the night sky and be moved using the stellarium programme
first take caps off telescope, turn telescope on(make sure everything is plugged in and switched on,checking all leads and sockets)
telescope automatically moves towards the west)
centre capella in finder scope(scope speed 5)
Synchronise coordinates on Capella ( object -> star -> named -> Capella -> Enter (2 seconds) -> Enter to sync)
move telescope away from capella
use the go-to key to get back to capella
Move to almaaz(HIP 23416) using the hipparcus catalogue method outlined in the script
Use Hip method again to move to Betelgeuse (HIP 27989), and bellatrix (HIP 25336)
open MaxIm DL Pro 5
exposure 1 sec start poor out of focus picture
change exposure to 0.1 sec, X bin 4 continuously taking images
use knobs on scope to unlock mirror and change the focal length, simultaneously slowly moving scope to get the star in the centre of the field of view of the CCD
get star in and out of focus and take picture
calibrate telescope to set on aldebaran
use focus (4 on pad) to get good focus with microfocuser that changes the camera not the mirror
take images in different exposuresmove to fainter section of sky, star cluster near aldebaran cluster 2 shows fringe from coolingtake 10 images to find saturation around 65000 for this CCD
move to 02 Tau and found bleeding and saturation at 10s, took multiple images at different exp times (1x1 binning)
found that simple auto dark callibration was on contiunued with this then took one without this

Weather - cloudy fairly poor visibility
* set up telescope, open dome, take off caps etc
* take picture of blank space, set up guide camera also
* twilight point scope at blank space look at cooling and non cooling effects
* target is betelgeuse, use to focus and synchronise camera
* move scope to pleiades, new target in order to take pictures of cluster, image with multiple stars
* centre on atlas and pleione
* look at error in plate scale as a function of flux ALL FRAMES!!!!!!!!!!!!!!!
* f[0].header this shows all the info about the image and the telescope
* shape(d) Out[40]: (1020, 1530) dx1 = d[0:500,:].sum(0) dx2 = d[501:,:].sum(0) plot(dx1) this will set a range on the x/y axis

time 10:30am arrived in dome. A Cozens, L Lenz D Bedingham S Boogert
poor weather conitions so no solar data could be recorded
used SLR camera to take images of boiler house in order to understand how the manual settings of the camera affect images
took 30 images with different exposure times and varying the ISO number, as ISO increases smaller exposure times are required so not to saturate the image.
The images are located
C:\users\astrodome\desktop\3_data\20171018_Solar
with two files showing the dark frame images taken to show the noise of the camera with the cap on the lens and light brick images taken at different exposure times with different ISO

10:30 dome. Bedingham, Cozens, Lenz
* good weather => took a few images with Canon SLR camera
* The following settings received best results: ISO=100, exposure time=1/4s to 1/8s, max. f-number
* Used rawkit Python package to transform .cr2 files into .tiff
* Applied Hough transformation to find circles in image
* Measured brick width L with ruler and received distance D from dome to boiler house brick via Google Maps
=> L = 22cm, D=104m
* From this calculated angle to be θ = 2*arctan((L/2)/D) = 0.117° = 0.22x(angular separation of sun(0.5°))
* Next steps: - take image of smooth white background to measure the vignetting effect of camera
- adjust parameters of Hough transformation to find correct circle

use DSLR to take white images to look at the natural vignetting effects of the camera, took many exposure times so to get an unsaturated image. Need to process these to get a pixel vs intensity curve to show that the fractional ratio of intensity does not depend on exposure. Also look at different colour channels and create a plot to show all 3
Then set up the telescope so as to record data, fit with sun filters and imaging source camera. Using ICcapture software.
Use shadow of the telescope to align, and adjust further with finder scope.
set telescope to the west of the sun to see it passing through the window, takes around 1min to fully pass no data recorded
Use DSLR to take images of the sun, lowering the exposure times to find an unsaturated image. Use circle finder code to analyse the intensity array across a diameter of the sun.
Attached Text files show the image numbers on the DSLR for varying exposure times ISO=100 for targets of the sun then a white light source evenly lit for investigating the vignetting effect.

10:30 at dome, D. Bedingham, L. Lenz
* cloudy weather => took no images of Sun
* Vignetting images from last week were not symmetric
=> will have to retake those images with diffuse light (outside) and a variety of exposure times to achieve different max/min intensity values,
the ratio of I_max/I_min should be approx the same throughout
Next steps:
* Take correct vignetting images with different exposure times and diffuse light
* Analyse new vignetting images and apply curve fitting to it => V(x) => can receive real intensity with I(x)*V_max/V(x)
* Estimate unscattered intensity f of Sun images
* Fit curve to unscattered intensity => Gaußian fit => should get data back (~Gaußian curve)
* Optimise f

looking into error in blue filter images taken previously
is an error in the programme with the readout, reboots and restarts did not solve this. Updated the verison of IC Capture from 2015 model to 2017, this had some minimal effect
Look at changing the Frames Per Second to a smaller amount (from 30 to 3.75) this did correct for the oscillation problem looking at blue sky
Move to try and take images of sun again with filter
Wait for sun to be away from tree.

Weather Conditions: Clear
Time: 22:40 - 1:50
Targets: Betelgeuse & Pleiades Cluster in RBG filters
Cameras Used: SBIG ST 8XME(camera 1) and SBIG ST-8300M(camera 2)
Both cooled to -20deg
Telescope already synchronised, moved and focused on Betelgeuse. Target too bright for filters. Kept saturating.
Moved to a new target, the star, Bellatrix. Again too bright for filters.
Moved to another new target, HIP26594. 15 images taken for all three filters RBG, exposure time 1.5s.
Then moved to the Pleiades, in narrow view camera (camera 1). We took ten images in each filter with exposure time 10s. And we took ten images in each of the green and blue filters with exposure time 40s.
We switched to camera 2, a wide view that could take an image of the whole cluster. The image is inverted in camera 2. We took 20 images with exposure time 0.4s with no filter.

* set to speed 5, center
* start exposure, bin 4, continuous, center object, speed 3
* adjust focus, unlock primary mirror clockwise 2 revolutions, bracketing process(see how the object is changing), object keeps moving, brightness changes, focus as much as possible, center it again speed 3, synchronize-object,star,named, click for 2 sec
* observede diffraction pattern- something is wrong with the camera, filter plate not moving, adjusting, fixed filter changing
* change exposure time to 0.3s, get star off center, focus on other, dimmer stars, adjust focus once more to see clearly
* discovered diffraction pattern in filter image
* took apart camera with help of Prof Boogert
* once camera filter in working condition, resumed observation
* took exposures of far field stars near Betelgeuse in order to focus the telescope
* shifted focus to plaidees - Atlas and Cleo
* used Astrometry in order to determine our location in the night sky
* once Atlas and Cleo found, took 0.1 interval exposures from 1 to 5 seconds until stars were saturating pixel value
* once pixel values saturated, shifted view to m41 orions nebula
* took one 7 second exposure

15/2/18 Began: 17:30
Started up telescope & opened observatory. Connected to camera with maximdl (disabled camera 2), turned on cooler to -15.
Found Capella @ LST=3:45, h= 22:27, rotated telescope mount. Changed declination to 46 degrees. Located star in viewfinder.
Began continuous 0.1s 4x4 binning image capture of CCD view. Moved telescope (speed 1) opposite to image view due to CCD being upside down, to centre Capella.
Go-to button used, caused telescope to move way off target. Recallibrating as a result. Now LST=4:15, so h = 22:57, relocated Capella. Centered etc.
With LST 4:27, Atlas found at h=0:32. dec 24 deg 6 min.
Used astrometry.net to work out stars from unknown image 1, located area in stellarium
Moved to bright stars (i.e atlas and pleione), checked again with astrometry and stellarium. Synced to Pleione HIP 17851 SAO 76229 on both telescope and stellarium (connected to telescope)
Centred on Pleione. Tested stellarium movement to other stars.
Centred on Atlas, took multiple images at several exposure times, saturating the image individually for both bright stars.
zeroed telescope, closed up dome.
Finished 20:00

Logbook for PH3010 Solar limb darkening mini-project, initial setup meeting
Present: DB, MA, JC, HS
Order of tasks for observation of the sun:
1) DO NOT STARE DIRECTLY AT SUN. DO NOT POINT UNPROTECTED TELESCOPE AT SUN
2) Go outside dome and check that sun will not be obscured by the tree, wind thingy. If it will be, will have to wait before able to take images of sun
3) Check solar filters are not damaged. Fit solar filters to main scope (and if using finder scope, fit solar filter to that). Fit CCTV lens to camera, camera to filters, filters to telescope.
4) Open dome, move opening so that allows shadow of telescope to be seen on dome wall
5) Use the shadow of the top scope (the one secured by two sets of three prongs) to align the telescope with the sun. When the shadows from both sets of prongs overlap, the telescope is (roughly) aligned with the sun
6) If using finder scope, use to target edge of sun.
7) Use IC Capture program to view camera feed (really need to jam the cable into the back of the camera to get the pc to detect it). In device-properties can control gain and exposure settings
8) Use live camera feed to target edge of sun and focus (unlock and use know on back of telescope)
9) Change declination of telescope and monitor live camera feed. Need to find centre-line of sun. This is when any change in declination results in the suns edge moving out of frame (away from centre, only changing declination in one direction will move it out of frame - the other will move it more in frame)
10) On telescope control setup-targets-terrestrial or astronomical
terrestrial will keep telescope at fixed angle, astronomical follows objects through the sky
11) Choose filter to image with. Point telescope as closely as possible to centre of sun and view image histogram. Adjust and exposure until the image is not fully saturating (has a narrow yellow bar - the zero readings - visible) but has as full a range of values as practical.
12) Return telescope to point at edge of sun, in the centre. In IC capture go to the timed capture settings. Choose an appropriate target folder and image capture filenames, set the image type to bmp, turn the 'auto display capture' to off and set an appropriate capture interval and number of captures.
Note: Sun subtends an angle of about 0.5 degrees. Previous years have taken 405 seconds worth of images for this project.
13) capture images. Repeat step 11 onwards for another filter

* Dome entered 10am. Present: MA, JC, HS, supervised by Dr. DB
* Telescope cover removed, solar filters put on
* camera and colour filters were already attached to telescope. setup checked just to be sure
* Telescope setup reviewed+approved by DB
* Dome doors opened, telescope turned on
* Moon was still visible in sky - dome doors moved to allow viewing of it
* Moon used for focus (coarse and fine), took a couple of images of nice craters
* Moon found by (roughly) lining it up with the telescope, then with the finder scope, then with the camera image
* Dome doors moved to allow viewing of sun, telescope slewed to find sun
* telescope shadow aligned on wall behind telescope
* telescope moved to bring the two rows of knobs into alignment (i.e. telescope pointing at sun)
* Using camera feed, approximate equator of sun found at one edge
* Test images taken
* Moon and test sun images stored in focus_images folder
* Colour image sets taken.
* All image sets performed by pointing telescope ahead of suns motion and switching to terrestrial mode - motion of sun across sky then carries sun across the frame of view.
* All image sets taken over 3 minutes 10 seconds. This time determined by timing a test run of the method.
* 1 image per second taken for the length of the image set.
* Used maximum gain for all image sets. Exposure determined by manually slewing across the sun and trialling different exposures. Aim was to get as close to having maximum pixel values in the image, without actually having any maxed out pixels
* Where necessary, solar eclipse glasses were used to directly view sun e.g. to determine if clouds were obstructing the sun, or just the area around it
* Clear Filter 1:
* Gain 799, exposure 1/1000 seconds
* trees obstructing parts of image set - produces obvious errors in dataset
* Clear Filter 2:
* Gain 1023, exposure 1/4000 seconds
* Blue Filter 1
* Gain 1023, exposure 1/154 seconds
* Some obstruction of sun by clouds
* Blue Filter 2
* Gain 1023, exposure 1/154 seconds
* Still some clouds, but far fewer than with Blue Filter 1
* Green Filter 1
* Gain 1023, exposure 1/308 seconds
* Lots of clouds
* Green 2
* Gain 1023, exposure 1/308 seconds
* Even more clouds
* Red 1
* Gain 1023, exposure 1/1241 seconds
* A few false starts (so the file indexing is messed up), but managed to get a good run of images
* Was not able to perform another run with the green filter, due to increasing cloud cover
* Dome doors repositioned above door to roof and closed.
* Solar filter removed and lens cap replaced. Filter stored back in its home.
* Telescope returned to 0h0d
* NOTE: Minor mix-up with imgae file names. All image sets are stored in the appropriate folders / .zips for the colour filter used, but the some image sets use the wrong colour name in the individual image filenames. Recommend handling image sets carefully / renaming appropriately when used.

* Present JC, AD
* Began cooling at 16:45 to -12 deg C (~90%)
* Filter wheel set to Clear, Red, Green, Blue
* Centred on Capella and took GPS-fix. Encountered problem: telescope believed it was -1h RA from Capella however this offset was constant.
* Edit: This seemed to just be an issue with the coordinates read-out on the paddle.
* Centred on M35 and took 1000x0.1s exposures to focus.
* Then took 60s exposure- significant effects of moonlight on image- change target to M36 (RA/DEC: 05 37 13.8/34 09 04)
* Light pollution significantly reduced suggesting moon was indeed the source.
* took 60s and 90s exp in all filters
* moved to (RA/DEC: 05 37 31/34 07 50) and repeated.
* took dark and bias frames before finishing observation at 9:30pm.

Test Images
M57 - Ring Nebula M56 - Globular Cluster- 1x60s Luminance image
- 9x60s Luminance images stacked to form a 6x60s image
- 1x109s Blue image
- 1x86s + 2x60s Green images
- 1x86s + 5x60s Red images
During the Dumbbell Nebula imaging the filters were accidentally changed due to the mouse scroll.
- Possible workarounds:
- Use autosave function to take images
- Check before taking a new single image

Connecting TWiki.MaximDL and TWiki.FocusMax to Python
Basic information on automating astrophotography with python here
And almost everything you need to know about Python and COM objects here.
(If you just want the basics, check this link and this Quick Guide.)
From iPython run the following commands as apropriate:

except:
# If makepy fails, generate manually and override

focuserRate = win32com.client.gencache.EnsureDispatch('MeadeLX200GPS.Focuser')
* this lines can be obtained from "makepy.py -i" command on your _lib/site-packages/win32com/client_ folder under your python installation directory
Obs. Object info can be obtained via the "combrowse.py" command on your _lib/site-packages/win32com/client_ folder under your python installation directory.
Objects should be under "Registered Type Libraries" and they contain more information of available methods and property.
MaximDL information are also available [[http://www.newastro.com/tutorials/maxim_objects.php][here]] and on [[http://www.cyanogen.com/help/maximdl/MaxIm-DL.htm][MaximDL Help]].

APIs:
* [[http://seal.web.cern.ch/seal/documents/minuit/mnusersguide.pdf][Seal Minuit]]
* [[http://iminuit.github.io/iminuit/api.html][iMinuit]]
*Performance (measured with Python %timeit() magic function):*
* PyMinuit: best of 3: 13.9 s per loop
* iMinuit: best of 3: 11 s per loop
*Conclusions:*
* iMinuit is easier to install than PyMinuit
* iMinuit is faster than PyMinuit
* iMinuit have more features than minuit (e.g. export to LaTeX and fake functions)
* Both detected and successfully minimized a 2D Gaussian on all the stars with same parameters
* PyMinuit "accidentely" fitted more Hot Pixels than iMinuit
* PyMinuit includes Simplex and Scan methods, which are not available on iMinuit
* PyMinuit is more stable - annoing bug in latest version cause segfault it limits, steps, ... are not set
Keep PyMinuit for now.

pre-requisite: have [[http://www.cygwin.com/][Cygwin]] installed and a GNU compiler.
Cygwin comes with python pre-installed, from there one can install new packages with:
* easy_install packageName
* pip install packageName
To use ==pip== you must install it first using ==easy_install pip==
The ==pip== method is favorable for it allows you to search, uninstall and upgrade packages easily.
==pip== guide:
* ==pip freeze== - display currently installed packages
* ==pip search packageName==
* ==pip install packageName [--upgrade]== - installs or upgrade an already installed package
* ==pip uninstall packageName== - uninstall a package
*Packages installed*
* ipython
* numpy
* scipy
* pyfits
*To be installed:*
* matplotlib
* opengl
* pyside
* pywin32 (don't support cygwin)
* pyminuit ([[http://code.google.com/p/pyminuit/wiki/HowToInstall][detailed guide]])
1 Download the required files: [[http://code.google.com/p/pyminuit/downloads/detail?name=Minuit-1_7_9-patch1.tar.gz][Minuit-1_7_9]] and [[http://pyminuit.googlecode.com/files/pyminuit-1.2.1.tgz][pyminuit-1.2.1]]
1 Extract and change to Minuit directory (under cygwin)
1 Compile Minuit with:
1 bash configure
make
make install
1 Change to pyminuit directory ( ==cd ../pyminuit-1.2.1== )
1 Build and install with: ==python setup.py install --with-minuit=/location/of/Minuit-1_7_9==
Abandoned. No pywin32 support, changing for full Windows python.

Ring Galaxy (NGC1291)
Protostar (IRAS 20324+4057) "The bizarre looking ring galaxy NGC 1291 in Eridanus.
These fairly rare types of galaxy are usually much fainter objects, but this one at "only" 33 million light years away is easily visible in modest size telescopes though the faint outer ring of material is much fainter than this.
Its strange appearance is the likely the result of a collision with another galaxy in the distant past.
20"CDK with FLI-PL6303e camera. LRGB. L: 70mins. RGB: 5/5/10mins" - Damian Peach
IRAS 20324+4057 is a Protostar in the Cygnus OB2 Association, 4,500 light-years (1,380 parsecs) away.
This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
INT: H-alpha
cyan ACS: F606W (V)
blue
ACS: F814W (I)

After turning telescope on, it successfully received GPS signal and did not started the usual RA movement.
The Camera was connected to Python via MaximDL
Telescope and Focuser connected to Python via the POTH Hub
Coordinates in agrement between Scope, Python and Stellarium
Target was set to be -0.1º RA from current telescope position and Python SlewToTarget was tested.
Telescope moved the right amount and stopped, both telescope and Python alerted when ready.
A second test was made with +0.5º RA. Also successfully.
Still with small (-0.1º RA/DEC and +0.5º RA) movements, Python SlewToCoordinates was tested successfully.
With the tests done, the telescope was moved to Vega via controled movements on Stellarium
Vega was inside the Camera Range, demonstrating that the Park Method works.
Vega was recentered (-0.01 on RA) and the telescope was manually synced.
During this test, movements as small as 0.003º on RA proved to have no effect whatsoever.
The next step was to test the focuser and the camera.
First, while still on continuous mode of the camera, the Python-Focuser connection was tested.
Python can read the position and move the focuser. Units are steps. 1 step = 20µm
Having confirmed that one can move the focuser with Python, Vega was taken out of focus to test if we could focus the star using a small

*Focus movements*
* Positive -> In
* Negative -> Out
*Tests*
The data below have a significant experimental error associated with the not fixed measuring equipment.
Also, they can have errors related to a possible angle between the measuring equipment and the in-out axis therefore, the real value would differ by a factor of cos(theta)
*out*
* move(-5000) - 1.86mm
* move(-5000) - 1.80mm
* move(-5000) - 1.86mm
* move(-5000) - 1.81mm
* move(-5000) - 1.88mm
* *mean = (1.842 ± 0.031)mm*
* move(-1000) - 0.31mm
* move(-1000) - 0.40mm
* move(-1000) - 0.44mm
* move(-1000) - 0.27mm
* move(-1000) - 0.45mm
* *mean = (0.378 ± 0.076)mm*
The out movement is coherent and 5000 steps is indeed equivalent to 5x1000 steps
This give 1 step aprox 0.37µm
*in*
* move(5000) - 1.52mm
* move(5000) - 1.55mm
* move(5000) - 1.52mm
* move(5000) - 1.48mm
* move(5000) - 1.57mm
* *mean = (1.528 ± 0.031)mm*
* move(1000) - 0.21mm
* move(1000) - 0.20mm
* move(1000) - 0.15mm
* move(1000) - 0.30mm
* move(1000) - 0.18mm
* *mean = (0.208 ± 0.050)mm*
The in movement is 25 to 50% smaller than the out movement (depending on the movement size) with larger movements closer to the equivalent out.
This give 1 step being between 0.2 and 0.3µm
*Conclusions*
The execution of the above movements led to the following conclusions:
* Focuser always finishes in a 'in-movement' (e.g. asking to move out will make the focuser goes more than needed and come back about 1mm)
* This causes the isMoving check to return before the focus being ready.
* Focuser limit less than aprox 30k steps when going in.
* When close to the limit, focuser will overstep (move(5000) caused the focuser to move 2.76mm)
* Focuser isn't ready when isMoving returns False.
* There's a time gap when a second comand will be accepted but not executed.

[[http://www.newastro.com/book_new/ebook/c2d.pdf][Diffraction aids]]
---------+++ Using a Bahtinov mask to find the focus:
Based on Laurie's idea and [[http://starryvistas.net/articles/focusmask/focusmask.aspx][this article]] a set of 144 images were taken.
3 images for each of the 48 moves made by the focuser. All the movements were 'in' moves of 250 steps.
The images had a 5s exposure time and a master dark (made of 10 dark) was made and reduced from the images.
On each image, a gaussian was fitted to the brightest star (142/144 success) and the amplitude and sigma median were taken for each set of 3 images per focuser position.
The data was then plotted and assumed to be in a quadratic form. The results can be seen on the images below.
For the Sigma X values, the minimum can be found at: 4841 steps
While Sigma Y minimum is at: 5411 steps
And the Amplitude maximum at: 6804 steps
According to [[LogBookAstronomyEntry0015]], the 2000 step (aprox 600µm) difference would be more than double the depth of field for the telescope [[http://starizona.com/acb/ccd/advtheoryfoc.aspx][(287µm on a f/10)]].
A visual analysis of the graphs would suggest a minimum and a maximum for Sigma Y and the Amplitude close to 6000 steps and, visually, the image at step 5750 (image set 23) is the sharpest presenting a nice 'X' diffraction pattern produced by the Bahtinov mask.

Proceeded to take another 120 dark frames at -7.5 degrees, as with coolers on 100% sensor temp would not go below -10.6 degrees.
Proceeded to take anothe 120 dark frames at -2.5 degrees.
CCD will then be reset to 0 degrees, and frames will be taken every 30 seconds as it is cooled from 0 to -10 degrees. The exposure time will be 2 seconds. Due to lack of time this will be postponed until next week.

---------+ Project meeting on 24 / 10 /2013
Present: Chris Haynes, Paul Hallam, Ryan Cheale, Dr Boogert, Professor Cowan.
Continued discussion on taking and analysis of dark frames.
Due to the dome not being cold enough during the day, it is difficult to cool the camera down to -15 or -20 celcius. Therefore, the remaining readings will be taken further into winter, when the dome is colder.
Objectives for analysis of dark frames:
* Plot a histogram of the -5°C, 60 second frame and compute the mean, median and standard deviation.
* Plot the column mean and consider the standard deviation for all columns.
* Plot the standard deviation as the square root of the mean and check to see if it's a Poisson Distribution.
Additionally, we should think about the dark current rate (the rate at which an electric current is generated in the chip due to the production of electrons and holes) and how to compensate for it.
We should also consider what the faintest star we could detect would be, looking at the point spread function of our telescope.

* Submitted Data obtained to [[Public.LogBookAstronomyEntry0026][Dark Log Book 30/10/13]] as a record for files
* For data analysis still need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.
Python
* Began the use of the canopy environment to begin data analysis in Python.
* Running into multiple problems with the canopy environment with plotting graphs
* Have made plots for the mean, standard deviation, max and min values of the data set T-05.0-NNN-E0600
* Struggling to create histogram plots, either the kernal or the environment tends to crash when trying to create a histogram of a single fit file
* Next steps:
* Produce median plots
* Refine code so only needs slight input alteration for other data sets
* Produce histograms and then further plots based off of the histograms
* begin analysis on cool down data.

A study into the variation of background pixel count with temperature.
Initial CCD temperature was recorded to be 18 degrees. Coolers were turned on and CCD cooled to 0 degrees over the course of an hour, to ensure the entirety of the CCD began at zero degrees for the following study.
Coolers were then set to cool the CCD to -10 degrees, and one second exposures were to be taken every 30 seconds for one hour over this cool down period.
The data shall be saved in the following format: Cooler_Study-001E001
Also this shall also provide 29s exposures between the 1s exposures, which shall appear like this: Cooler_Study-001E029. This data will not be analysed.
When this collection of data has been finished, CCD was at a constant -10 degrees. The CCD coolers were switched off, and the CCD warmed back up to room temperature. Using the same method, one second exposures was taken every 30 seconds for one hour over this period.
The data shall be saved in the following format: Cooler_Study_2-001E001
Again this will also produce data that will not be analysed, in the form of: Cooler_Study_2-001E029
Room temperature in this case is 25.6 degrees.

---------+++ Telescope Set Up
* Target Delta Cephei selected using Stellarium and AAVSO catalogs
* Open shutters (ropes, pull apart, tie off ropes, motor control
* Turn power on
* Press power switch on telescope
* Removelens caps
* Point towards Vega
* Line up with finer scope
* Take continuous frames 0.1s
* Center Vega in frame
* Synchronise Vega with Maxim DL and Stellarium
---------+++ Target Information
* Pulsating Variable star, magnitude variation 3.5 - 4.4, Δm = 0.9
* Period 5.4 days
* Next maximum, 07/12/2013, 9:32
* RA: 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From simulated light curve - expected Δm(max) = 0.26, expected Δm(min) = 0.01
* From light curve of Delta Cephei, and time of next maximum, we believe the magnitude should be decreasing
* Companion star HIP 110988 used as a reference star
---------+++ Initial Observation of Delta Cephei
* Centered on Delta Cephei - did not use Stellarium as could move telescope through the pole
* Frames were taken using different filters, initial exposure times:
* No filters - 1s
* Blue filter - 10s
* Green filter - 3s
* Red filter - 3s
* Took sample frames using this-set up, max pixel count was found using Python
* Re-evaluate exposure time to ensure max pixel count was in the range 55000 - 60000
* Re-evaluated exposure times:
* Focus filter - 1.1s
* No filter - 1s
* Blue filter - 10s
* Green filter - 5.1s
* Red filter - 3.3s
* Decided to take 5 repeats for each of these, and 10 repeats for Dark and Bias frames
* Autosave feature was used to take a sample set of data
* Residual image of Star found on Dark frames - low pixel count
* Implemented a 'Trash' frame before the Dark frame to attempt to remove this -> some residual image still remained
---------+++ Observation of Delta Cephei
* Autosave feature took approximately 10 - 15 minutes to run
* Approximately three runs were taken per hour
* Delta Cephei was observed for 5 - 6 hours
---------+++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope
* Turn off camera
* Turn off telescope
* Put cover back on camera
* Close dome shutters
* Turn off PC monitors
* Turn off lights and leave dome

20140213 LN
Reasonably clear and forecast to be good. Worth a try to get some practice in.
* CCD at -15oC
* Aligned to capella - very high in sky.
* Went down from 46 to 37 DE to theta_aur as capella saturates the camera.
* Take subframes to practice focussing. Recorded 400 frames of theat_aur for analysis later. SNR is good as super bright. Peak around 30000 ADU. Jumps around A LOT so will have to align by centroid. Then can have a look at PSF.
* Exposure 0.1s
* 300 exposures recorded in 10m12s
* 400 exposures recorded in 13m37s *Sat bhatinov mask carefully on front of scope. Recorded 50 images with same setup as before. Not so clear.
* Exposure 0.5s
* Not so clear. Pattern seems very small indeed on CCD compared to internet images. Collimation is definitely poor and its windy so don't expect it to be great. Anyway, reasonably good in focus.
* Having a look at the Pleiades. Too extended to see anything nice and certainly with the seeing. The stars are very bright and the nebulosity not so, so quite hard to observe under these conditions.
* Imaged Andromeda ok. 30s exposures.

* Frames were taken using different filters and exposure times
* Unlike previous observations images were near saturation at original exposure times, as a result the exposure times were lowered to 0.72 of the original.
* This provided the following exposure times:
* Focus Filter = 0.8s
* No Filter = 0.7s
* Blue Filter = 7.2s
* Green Filter = 3.7s
* Red Filter = 2.4s

Using the spectrometer to find the brightest spectral line in mercury and Find the best micrometer reading for the angle of the camera.
Camera was ST-7E, Setup SBIG Universal.
Temperature for all the images was -6.5 deg C.
*Focus*
Exposure time: 0.1s; Grating distance 1.814mm; Camera angle micrometer reading 2.495 (heavily sloped)
Used continuous range to find a reasonable staring point.
Used range of 18mm to 20.5 mm in steps of 0.5
Reduced range to 19mm to 20.5mm in steps of 0.10
Reduced range further to 19.50mm to 19.80mm in steps of 0.05
*Camera Angle*
Exposure time: 0.1s; Grating distance 1.814mm; Focus distance was 19.60mm for this
Used continuous range to find staring point.
Used range of 2.50mm to 5.50mm in increments of 0.5mm to start.
Reduced range to 4.00mm to 5.00mm in steps of 0.10mm
Reduced range further to 4.45mm to 4.65mm in steps of 0.05mm
Found the best angle to be _4.60mm_
*Brightest Peak Data*
Looking through the spectrum the brightest peak, found at 4.00mm in grating micrometer.
This was saturated so the lamp was moved back by 5cm which was still saturated, then we moved it back by another 5cm which put the lamp back from the optical fibre by 25cm. This reduced saturation where refocus was done. Seemed to saturate at 50,000 confirming it was brightest peak.
Used this to check the focus and recalculate.
used a range from 19.50mm to 20.50mm in steps of 0.10mm
Found best focus distance on micrometer to be _20.10mm_

27th Oct 2014 Msc Observation.
*Begun:* 18:30
*Finished:* 22:30
Conditions: Mostly clear, a little muggy. No cloud coverage.
Begun observation session with a run down of the procedure to prepare the dome.
*Dome Procedure:*
-
Enter dome
- Close the hatch to prevent heat rising and entering the dome. The floors beneath are heated which causes a ‘chimney’ like effect if the hatch is left open as the hot air from below will rise up through it. Ideally the scope and dome should remain cool so noise due to thermal fluctuations is kept to a minimum.
- In the Maxim DL suiteconnect to the telescope. This allows control of the camera for example you can set exposure times and capture images from the program.
- Enable the CCD cooler in Maxim. This should be done ~1 hour before taking exposures. If you take observations too soon after enabling the cooler you get a ring like effect on your observations around the outer area of the frame. The ring progresses further to the sides of the frame as the CCD cools until it eventually disappears.The set-point of the cooler is set to -10 degrees celcius and the CCD itself fluctuated around this point slightly once the cooler had taken full effect.
- Untie the ropes that control the shutter of the dome. Pull on ropes to open the shutter of dome, if the shutters do not open with ease, there is a long stick with a metal prod at one end which can be used to manually push the shutters open from near the top of the dome.
- Once shutter is open, tie the ropes off again to make sure that they are kept out the way of the moving parts of the done which can rotate bothe counter and clock-wise
- Using the door on side of dome, go outside and do some preliminary naked eye observations to find an interesting object to observe (this is important for aligning the telescope as detailed later on). This allows you to plan roughly where the telescope and open shutter should be pointing to allow unrestricted viewing.
- Using the dome control unit, align the dome opening with what you want to observe.
- When finished observing, realign both the dome and telescope to their origional position. Close the dome shutters and tie up the ropes.
To begin making observations you need to align the telescope to a bright object in the sky and then enable tracking. Tracking corrects the position of the telescope relative to the sedereal motion of the stars. This is necessary because the field of view of the telescope is so narrow if it was left stationary, the object you are observing will move out of frame. To align the telescope, the first step is to identify a bright object visible to the naked eye in the nights sky. You can acess the roof from the dome via. the door on the side. Once on the roof you are able to evaluate potential targets. We identified the star Vega (25ly away, 2.1M0, alpha lyrae - the brightest star in the lyra constellation and 5th brighest in the night's sky). The star charts provided in the program stellarium coupled with manual positional measurements allow you to identify the star you are looking at with the naked eye.
Once a object in the sky has been chosen, the next step is to align the telescope to enable the activation of tracking.
- *Telescope Alignment:*
-
Use a high speed on the control paddle (speed button -> 9 is fastest, 1 is slowest on number pad) to crudely align the scope with what you want to observe using the arrow buttons. This can be done roughly by eye by lining up the two bolts on the side of the telescope with what you are looking for.
- Then use the viewfinder which has a set of crosshairs to align the scope more accurately with the object in the sky. A medium speed setting on the paddle can be used to move the scope with a greater deal of precision.
- Once the crosshairs are centred on the object you wish to view, take an exposure in the maxim DL suite. Once the image has been taken and downloaded you can adjust the scope to get the object centred in the frame. If you set maxim DL to take continuous ~1s exposures you can get a better sense of the best way to align scope and object.
- Once the scope is aligned, enable GPS lock. This continuously corrects the scope to account for the rotation of the earth. The field of view of the scope is very narrow causing the object you are observing to move through the frame if the scope remains stationary.
- Once tracking is enabled, the scope should keep the object you are trying to view in frame automatically.
- Using the control paddle, tell the telescope which star/object it is currently aligned to
- With the telescope connected to stellarium which now allows you to control the scope through the program itself. Using the star charts, you can align the scope to stars/objects shown in stelarrium. (Wait for the ‘beep’ if you move the scope in the program. The scope moves quickly at first but then makes finer corrections to ensure the scope is aligned well. The 'beep' occurs once the telescope is properly aligned, it can take some time ~20-30 secs).
- While repositioning the telescope it is important to be aware of it's orientation with respect to it's base. The telescope is capable of flipping over on itself which can cause the CCD attatchment to collide with the stand. In a situation where this may happen, power down the telescope via the power controls located on its stand immediately.
With the telescope aligned you can control where it is looking via. the stellarium program. Multiple exposures of Vega were taken at different exposure lengths using the Maxim DL program.
Using stellarium, the telescope was then trained on the open cluster M-39 in the constellation cyganus (800ly away from earth). Again took multiple exposures. The cluster is composed of a number of stars. Using the star chart in stellarrium the star patterns were compared to that shown in the exposure allowing for individual identification of the stars the cluster is made up of.
You have the ability to manually focus the telescope. If it is out of focus the exposures of stars can present as donuts (dark centres with bright outer ring) or they seem flat and blurred at it's edges. The procedue to manually focus the telescope is first to 'unlock' the mechanism. There are two dials, the shorter one can be rotated to unlock the device allowing the second longer dial to be turned focusing the telescope.
Last target of the night was the andromeda galaxy known as M-31 (as it is a messier object) and is 2.5x106 ly away from earth and the closest spiral galaxy to the milky way group. This galaxy has a mass ~ 1.5x10^12 M0. 10 exposures were taken one after the other with the intention of eventually using them to form 1 image with considerably less noise.
An interesting point to note is that movement of the atmosphere above the telescope can cause exposures to shift in and out of focus. This was made evident as during continuous exposures of M-39, the stars were alternating between being in focus and out of focus.
The exposures taken during the night of observation are attached to this post.

*Observations of the Spectrum of Betelgeuse*
Started looking at Capella. Using a small sheet of tracing paper to allign the star in the optic fibre coupling. With Capella at a high Altitude we switched to Betelgeuse as a target to make allignment easier.
Viewed Capella at
5hrs 20' 30'' RA
45deg 8' 2'' DEC
with the micrometer at Grating-4mm, Angle-3.25mm, Focus 20.2mm.
changed the RA 5'' either side to align it centrally while observing the intensity recieved.
*Betelgeuse*
Next look at Betelgeuse,
5hrs 58' 32' RA
6deg 25' 30'' DEC
Took a 30s exposure at 4mm to look at the spectrum as best as possible. Then took 60s exposures of Betelgeuse between 0mm and 10mm in steps of 0.5mm.
After Betelgeuse we briefly moved to the Orion nebula however it was too dim to observe.
*Pollux*
7hrs 46' 14'' RA
27deg 59' 18'' DEC
Again took 60s exposures from 0mm on the grating position micrometer too 10mm in steps of 0.5mm.

Supernovae: PSN J07285387+3349106, RA: 07:28:53.87, Dec: +33:49:10.6, z = 0.013790
One frame was taken at 120s exposure. Stars were cross checked with Stellarium and were found to be low magnitude (10-16). Two other galaxies were also clearly visible, NGC2385 and NGC2389. The cooling ring was still visible at the edges of the frame. This location was chosen for the target of this observation due to the number of low magnitude stars, and the presence of three galaxies.
Uploaded a frame to astrometry.net
Experimented with 180s exposure, decided to use 120s.
Stacked frames using MaximDL built in image stacker to invstigate noise reduction.
Images taken:
Data was taken in bursts of 9 images, 3 Light Frames with 120s exposure, 3 Dark Frames at 120s exposure and 3 Bias frames.
Dome was realigned every 2 bursts to ensure unobstructed view of the sky.

---------+ 2015 05 20 LN DSLR Observation
* Trying out DSLR on back of scope
* Benefit - easy live video to investigate focussing, wide field of view
---------++ 20:30 start
* Dismounted SBIG camera (in case)
* Canon DSLR bayonet adapter + BADER 2" - T/2 Nosepiece on back of micro-focuser
* Observed Moon, Venus & Jupiter during twilight ~ 21:40
* Aligned & synchronised to artturus star to the south as visible to the naked eye
* image of M3 globular cluster ~ magnitude 6 - can make out ok in photos but still blue sky background as still slightly light
* 2155
* Trial of Deep sky object - still lightish but will keep iterating over objects
* Bodes Nebula mag 6.9
* Of note is that the DSLR is slim enough for a polar flip of the mount. Haven't, but can.
* Whirlpool Galaxy
* Getting better images but can only really see core of galaxy - still to much sky glow
From images of a single bright star or say of Jupiter and it's moons, you can see what appears to be both coma and chromatic aberration. The edges of non-point like objects have an orange tinge on one side and a blueish tinge on the other. Jupiter is relatively low just now so there is a strong affect from the atmosphere / imaging but still Jupiter had an asymmetric tinge. The moons were also quite distorted. Although the 'live view' gives you some indication, it simulates the exposure settings and can distort the image a little. Best to take images directly and zoom in to compare. Not too different from live view though.
* Telescope likely needs collimation, but the trouble is finding a good enough night for to be able to observe any improvement.
Sky much darker now. While no clouds around, there is a bit of haze - can't see huge multitude of stars.
* Starting at 3845 images of great cluster in hercules.

---------++ *Before taking data*
* Time of turn on: 18.20.
* Cooler set to -7 degrees.
* Temp at -6.9 degrees at 18.30.
* Center the telescope on Vega.
* Aling the telescope to Vega. (~Mode on the controller)
* Speed 5 and later 3 on controller while focusing on Vega.
* Microfocuser used to fine focus.
* Speed 3 to place Vega in the center of the image.
---------+++ Alpha Persei Cluster (Cr 39, Mel 20)
* We chose our cluster as the Alpha Persei cluster.
* To focus on the cluster we chose a nearby bright star Mirphak.
* We used it to correct our ofocusing and we synched Stellarium wityh the telescope.
* We choice a patch of the cluster (HIP16001) and took 10 vimages of 10 second exposures. ( x binning set to 1, x anmd y originally inverted, this was reversed)
* 5 bias frames and dark frames of 5 1min exposure.
* Took 3 40 s red.
* Took 3 40-s gtreen.
* Took 3 90 s blue.
*
* Move to a different patch (around RA:3h29min29s, DEC:49deg44'16")
* Ian joined us at 20:00
* 3 images of 60s visual.
* 3 images of 120s red.
* 3 images of 120s green.
* Finished taking data at 8.30 pm.
---------+++ Dark and bias frames
* Started taking dark frames. 5 images of 120s.
* Take 10 bias aswell.
Observation finished at 8.56pm.

The aim of the session was to modify the parameters of the camera. Using only OpenCv it was impossible to set the camera's parameters with known units.
py-ic-imaging-control was downloaded from: https://github.com/morefigs/py-ic-imaging-control
py-ic-imaging-control is a python wrapper for the IC imaging control software development kit from the imaging source (TIS). It provides control to TIS cameras, and can serve as an alternative to using OpenCv to access the cameras parameters.

The DMK camera was fixed to a tripod and pointed at the moon.
Run1: Gain set to 180 and images were recorded of the moon at a frame rate of 7.5 frames per second. The algorithm left the exposure setting on 1 as the image was not over or under exposed on this setting.
Run2: Gain was increased to 1023. The images were over exposed and the algorithm accounted for this by changing the exposure setting in increments of 1. It was noted that this was very slow to respond to large and sudden changes in conditions.
Run3: The code was modified such that the amount the algorithm changed the exposure setting depended on the number of pixels that were saturated. This massively decreased the time the algorithm took to find the correct exposure setting. See screen shot.
Images were also taken of Orion's Nebula, see image file names for parameter settings.

Az/Alt: 318deg 44'20''/38deg34'50''
Took testing pictures: Cooling_1 and cooling_2, can be seen a ring surrounded by the ice. Secong image shows larger ring, meaning hte camera is cooling down
Cooling_3 image is clear and even
Checked the wether with met office, clouds are exopected to clear for the rest of the night
Finding the star by eye, alighning the tescope, using stllarium found it was Procyon
As it wasn't clear that the star is Procyon, checked with Rigel
Took images of the delta cep with no filter and with filters: red, green, blue and spectroscope. Aimed for 50 000 pixel value - the closest to the maximum possible p.v.
Exposure time was increased as different filters were applied, because different filters obsurb more light.
Cloudy weather led to taking many pictures for blue filter with longer exp time, 16 sec.

Please edit and put your text etc. here
---------+ Finding focus of optical fibre
* The focus of the optical fibre was found by taking a relative distance between the lens and the position of the optical fibre, and measuring the amplitude of a spectral line from the laser found at 3.5mm.
* taken at 1mm intervals between 230m and 270mm.
* Fit with hyperbolae as approximation
* distance measured with ruler so very approximate i.e ±1mm
* Best focus was found at 250mm±2mm
* Iris was almost closed as the laser would saturate camera at shortest exposure.
* also took more data as SBIG ST-7E was cooling.
* Just need extra part to connect firewire camera, so that the alignment can be competed.

Please edit and put your text etc. here
---------+ Focussing Beam Splitter
* To find best focus should be able to focus onto a single fibre, once one illuminated, in focus. will have to use extension rings for optical fibre.
* CCD camera can then be adjusted until in focus.
* Focus by shifting backwards and forwards on rails.
* Find focus of camera with max intensity and minimum width of laser.
* Use diffuser or neutral density filter, will need neutral density filter.
* Make two plots of intensity on camera and fiber and adjust until peaks overlap.
* Such that there are two plots which look similar to:
---------+ Aligning Beam Splitter
* Align by moving the mirror horizontally and vertically until maximum intensity
* possibly get 3 more irises, to control aperture at camera, fibre and entry, to make sure always have good alignment.
* As now in focus, can scan around fibres and find the relative positions compared to the end where they are arranged into line.
* This could help with finding best position of ray on camera
* Look up mirror and see how much change in angle before lost fibre, one full turn until laser out of view.
* try to get two irises as far away from each other for best alignment.
* once part for CCD arrives, move around and find relative positions on camera to positions on optical fibre.
---------+ Relating to telescope
* Have to use larger beam size so that f# is the same as the telescope, f# = 10,
* currently 3 dioptre lens, so 1/3 m focal length, this means need a beam diameter of 33.3 mm or a longer focal length.
* as , where f is the focal length, d is the diameter of beam or aperture and f# is the f number.
* consider which camera to be used.
* beam splitter reflects 30% and transmits 70% so check this.
---------+ testing intensity
* tested the intensity at reflection and transmission, with diffuser and tissue in front of laser, tissue made intensity vary substantially so averaged over five frames, the reflection intensity was found to be 3% of the transmission intensity, however there could be problems with focus and alignment at the refection, need better analysis of this.

---------+ Aligning Camera and optical fiber
* Spectrum images,
* Exposure: 0.1s
* Temp: 10 deg
* used subframes around spectral to speed up
* FireWire camera * Exposure: 1/500 s
* The FireWire camera was attached to the beam splitter and connected to IC capture
* Optical fiber was attached using a spacer to approximate the same focal length as the FireWire CCD
* Initially an approximate focus was found on the FireWire camera.
* Then the angle of the mirror was adjusted vertically such that the laser beam was scanned vertically.
* images of the position on the CCD and the spectrum were taken at a range of positions.
* The amplitude of the spectral line was then recorded with position on the CCD.
* This gave a plot shown below for the maximum intensity. i.e centre of fiber
*
* This was then repeated for a scan horizontally, which gave the plot below.
* The best positions were found to be at [190,218] pixels, i.e 190 pixels across and 218 pixels down
* The the focus of the image was to be found.
* The box which the beam splitter and camera is attached to was placed on the rails and scanned backwards and forwards using a ruler for approximate focal length.
* Images were recorded for both the camera and optical fiber, and the amplitudes were plotted against focal length.

Please edit and put your text etc. here
---------+ Alignment of Camera and Optical Fiber
* SBIG camera,
* Temp: 10deg
* Exposure: 0.1s
* subframe around fibers
* FireWire Camera,
* Exposure: 1/500 s
* Took focus measurements first by moving beam splitter to find best focus.
* Best focus was found by subtraction background of spectral line image and summing pixels
* Best focus for image was found by finding max pixel value
*
* The optical fiber focussed ~6mm from the FireWire camera
* Optical fiber was adjusted such that it is as far out as possible using the smallest spacer, and the camera was adjusted so that it was as close to the beam splitter as possible.
* This was to close the 6mm gap found earlier
* The fiber and camera were then realigned as the FireWire camera will have been rotated slightly and moved out of alignment.
* Both horizontal and vertical alignment were used and the best positions were found at maximum intensity the same as for the focus.
*
---------+ Attachment of guidescope
* Two mounts for the dovetail plates attached on the top of telescope, plate then attached.
* The two dovetail plate mounts for the bottom of the telescope have to have small section removed due to bolts on the telescope which were in the way.
* Bottom dovetail plate then attached.
* guidescope rings and guidescope attached to the top plate
* counterweight attached to bottom.
* The telescope was then approximately balanced by adjusting the counterweights position on the plate and by unscrewing the counterweights so they were further from the OTA.

Please edit and put your text etc. here
---------+ Alignment of fiber horizontally and vertically
* SBIG camera for spectrometer:
* Exposure: 0.1s
* Temp: 10 deg
* Subframes
* FireWire Camera:
* records video at 30fps
* Exposure: 1/500 s
* Approximate focus was first found. set at 255 mm
* The mirror was adjusted horizontally such that the laser moved horizontally in the camera frame.
* Images were then taken of both the spectral line of the laser and the image on the FireWire camera as it was scanned, 40 images were taken.
* The maximum intensity of the beam and its position were recorded on the FireWire camera and the summed intensity was recorded for the spectrum with removal of backgorund.
* The intensity on the spectral line was then plotted against the position on the FireWire camera, this gave a plot shown below.
* The peak position on the above plot is then used to set the position of the beam on the camera, which is approximately at a position of 200 pixels.
* Once the position has been set the process was repeated scanning this time vertically, this gave a plot as shown below.
* The best position for the beam to be on the camera for max intensity at this stage is then at pixel values [200,216].
---------+ Focussing the beam
* Once the beam has been set to the best position as found earlier the camera and optical fiber were adjusted between distances of 220mm-290mm in 2mm intervals to find the best focus.
* Here the same measurements as before were made. The intensity of the spectral line and the maximum intensity of the FireWire camera are plotted against focal distance.
* The plot of both the camera and optical fiber is shown below.
* With this image the approximate best focus was set at 250mm
---------+ Repeat of alignment
* The alignment process was then repeated as before, this gave the below plots.
* These gave maxima at a pixel position of [201,217], The image below shows the position of the laser of the camera at this point:
---------+ Horizontal Scans at different Focal lengths
* For 6 different focal lengths, 240,244,248,252,256,260, a horizontal scan of the laser was recored on the camera and the spectrometer. This range was chosen as in the above focus plots, this is where the intensity flattens.
* For each of these the position of the laser of the FireWire camera was plotted against the total intensity of the fibers.
* The aim was that the focal length which gives the smallest width of a spectral line is the correct focus.
* The plot below shows the intensity plot for each of the focal lengths, and the widths of the line.
* This shows the widths does not change much in that range, this could be due to the fact that the focus is smaller than the size of the optical fiber, therefore, the integrated amplitude will remain the same in this range.
* Therefore, by selecting a single fiber to integrate the intensity over, it should be possible to find focus.
* The below plot shows the same results for a single fiber
* This shows that the width of the line drops in the range of 252-256 mm .
* by fitting a Gaussian function to both the image on the firewire camera and the plots above, the widths could be plotted against the focal length for both.
* Each of these were then fit with a hyperbola function,
* This gave parameters of,
| parameter | FireWire | Fiber |
| mean | 254.8±1.2 | 255.2±1.1 |
| a | 4.28±0.92 | 6.12±1.25 |

Saqib Hussain + Jervis Ong Arrived at 16:24, weather clear
* AA arrived 17:30
* Took example flats with both cameras
* Setup telescope, synched on Vega
* focused the telescope on a star
* took a few dark frames to distinguish dust on the telescope
* Primary observation target identified : rho Cyg- 73 Cyg - HIG 106481, right ascension = 21h 33m 58.85298s, declination = 45° 35′ 29.1 "
* Checked the camera cooler temperatures: -5.2 for ST8 and -15.0 for ST8300
* Took exposures with exposure time 0.1s for ST8300 and 0.5s for ST8
* For ST8300, file names begin with odd alphabets (a,c and so on) whereas for ST8 file names begin with even alphabets
* The data is compiled as below:
| Telescope | Exposure time/s | Time frame/minutes | No.of Images | File starts with |
| ST8300 | 0.1 | 12 | 66 | a |
| ST8 | 0.5 | 12 | 45 | b |
| ST8300 | 0.1 | 16 | 100 | c |
| ST8 | 0.5 | 11 | 45 | d |
| ST8300 | 0.1 | 9 | 45 | e |
| ST8 | 0.5 | | 45 | f |
* Moved on to collate data for atmospheric extinction
* For ST8, we tried to take images with different filters (luminescence, red, green, blue) for an exposure time of 0.4s
* However, due to technical problems we were unable to take images with colour filters
* We continued taking unfiltered images every 10 minutes (as the star moved from the azimuth to the horizon), saving them as files beginning with L
* Exposure time is 0.5s for every image
* Cooling power was within the range of 40 and 49%
* Data are as follows:
| Time | File Name |
| 2158 | L1 |
| 2208 | L2 |
| 2218 | L3 |
| 2228 | L4 |
| 2238 | L5 |
| 2248 | L6 |
| 2258 | L7 |
| 2308 | L8 |
| 2318 | L9 |
| 2328 | L10 |
| 2338 | L11 |
* took a photo of Andromeda
* Turned the coolers off, disconnected the cameras. Double checked everything was disconnected.
* Exported data into USB stick.

set up procedure
* check for damages on solar filters
* solar fillters on finders scope and main scope
* mount camrea
* use a SCT connector
* screw onto fliter and telescop
* RGB filter
* clip onto tube
* C-mount to 1.25 inch tube
* screw onto camera
* camera
* mount camera unto telescope by unscrewing the big ccd camera
* fire wire cable connected to the camera(clips in)
* with them, covered you can open the dome doors
* switch on telescope
things differe form a normal observation:
* use different type of camera( imaging source dmk 21af04.as)
* use a different piece of software
* stop the tracking
IC capture
* open IC capture
* click camear being used
* device properties click off auto gain and exposure
* check if histogram isnt saturated
* adjust exposure so it is not saturated
* saving sequnece of image
* capture -> squence settings
* file name and target, pick a directory(desktop/data/YYYYMMDD) -> index at 1
* file type BMP
* Automated sequence -> interval at 1 sec -> end sequence after 400 Frames
* capture -> sequence timer -> start timer
how to turn off tracking
* set up -> enter
* targets -> enter
* trestral or astonamical ->enter
we are going to be using 2016-11-02 data

time: 17:22 arrived in dome. ENK JT AS AC AA
remove rain cover from telescope
open doors of dome (ropes(tie up), bolts)
go onto roof and observe sky
select Capella(HIP 24608) on Stellarium
RA/Dec 5h17m57.85s / 46deg 00' 40.4''
h(capella) = LST(egham) - \alpha = 1h41m52.8s(egham) - 5h17m57.85s(capella) =-3h36m5.05s
rotate dome to correct direction
callibrate telescope - move telescope manually to point at Capella, it can then know its position on the night sky and be moved using the stellarium programme
first take caps off telescope, turn telescope on(make sure everything is plugged in and switched on,checking all leads and sockets)
telescope automatically moves towards the west)
centre capella in finder scope(scope speed 5)
Synchronise coordinates on Capella ( object -> star -> named -> Capella -> Enter (2 seconds) -> Enter to sync)
move telescope away from capella
use the go-to key to get back to capella
Move to almaaz(HIP 23416) using the hipparcus catalogue method outlined in the script
Use Hip method again to move to Betelgeuse (HIP 27989), and bellatrix (HIP 25336)
open MaxIm DL Pro 5
exposure 1 sec start poor out of focus picture
change exposure to 0.1 sec, X bin 4 continuously taking images
use knobs on scope to unlock mirror and change the focal length, simultaneously slowly moving scope to get the star in the centre of the field of view of the CCD
get star in and out of focus and take picture
calibrate telescope to set on aldebaran
use focus (4 on pad) to get good focus with microfocuser that changes the camera not the mirror
take images in different exposuresmove to fainter section of sky, star cluster near aldebaran cluster 2 shows fringe from coolingtake 10 images to find saturation around 65000 for this CCD
move to 02 Tau and found bleeding and saturation at 10s, took multiple images at different exp times (1x1 binning)
found that simple auto dark callibration was on contiunued with this then took one without this

time 10:30am arrived in dome. A Cozens, L Lenz D Bedingham S Boogert
poor weather conitions so no solar data could be recorded
used SLR camera to take images of boiler house in order to understand how the manual settings of the camera affect images
took 30 images with different exposure times and varying the ISO number, as ISO increases smaller exposure times are required so not to saturate the image.
The images are located
C:\users\astrodome\desktop\3_data\20171018_Solar
with two files showing the dark frame images taken to show the noise of the camera with the cap on the lens and light brick images taken at different exposure times with different ISO

10:30 dome. Bedingham, Cozens, Lenz
* good weather => took a few images with Canon SLR camera
* The following settings received best results: ISO=100, exposure time=1/4s to 1/8s, max. f-number
* Used rawkit Python package to transform .cr2 files into .tiff
* Applied Hough transformation to find circles in image
* Measured brick width L with ruler and received distance D from dome to boiler house brick via Google Maps
=> L = 22cm, D=104m
* From this calculated angle to be θ = 2*arctan((L/2)/D) = 0.117° = 0.22x(angular separation of sun(0.5°))
* Next steps: - take image of smooth white background to measure the vignetting effect of camera
- adjust parameters of Hough transformation to find correct circle

Time 10:30am-1pm in dome, A Cozens, L Lenz, D Bedingham, S Boogert
Weather cloudy, intermittently clear
use DSLR to take white images to look at the natural vignetting effects of the camera, took many exposure times so to get an unsaturated image. Need to process these to get a pixel vs intensity curve to show that the fractional ratio of intensity does not depend on exposure. Also look at different colour channels and create a plot to show all 3
Then set up the telescope so as to record data, fit with sun filters and imaging source camera. Using ICcapture software.
Use shadow of the telescope to align, and adjust further with finder scope.
set telescope to the west of the sun to see it passing through the window, takes around 1min to fully pass no data recorded
Use DSLR to take images of the sun, lowering the exposure times to find an unsaturated image. Use circle finder code to analyse the intensity array across a diameter of the sun.
Attached Text files show the image numbers on the DSLR for varying exposure times ISO=100 for targets of the sun then a white light source evenly lit for investigating the vignetting effect.

* cloudy weather => took no images of Sun
* Vignetting images from last week were not symmetric
=> will have to retake those images with diffuse light (outside) and a variety of exposure times to achieve different max/min intensity values,
the ratio of I_max/I_min should be approx the same throughout
Next steps:
* Take correct vignetting images with different exposure times and diffuse light
* Analyse new vignetting images and apply curve fitting to it => V(x) => can receive real intensity with I(x)*V_max/V(x)
* Estimate unscattered intensity f of Sun images
* Fit curve to unscattered intensity => Gaußian fit => should get data back (~Gaußian curve)
* Optimise f

Time in dome: 10:00 A Cozens, L Lenz, D Bedingham, S Boogert
looking into error in blue filter images taken previously
is an error in the programme with the readout, reboots and restarts did not solve this. Updated the verison of IC Capture from 2015 model to 2017, this had some minimal effect
Look at changing the Frames Per Second to a smaller amount (from 30 to 3.75) this did correct for the oscillation problem looking at blue sky
Move to try and take images of sun again with filter
Wait for sun to be away from tree.

Weather Conditions: Clear
Time: 22:40 - 1:50
Targets: Betelgeuse & Pleiades Cluster in RBG filters
Cameras Used: SBIG ST 8XME(camera 1) and SBIG ST-8300M(camera 2)
Both cooled to -20deg
Telescope already synchronised, moved and focused on Betelgeuse. Target too bright for filters. Kept saturating.
Moved to a new target, the star, Bellatrix. Again too bright for filters.
Moved to another new target, HIP26594. 15 images taken for all three filters RBG, exposure time 1.5s.
Then moved to the Pleiades, in narrow view camera (camera 1). We took ten images in each filter with exposure time 10s. And we took ten images in each of the green and blue filters with exposure time 40s.
We switched to camera 2, a wide view that could take an image of the whole cluster. The image is inverted in camera 2. We took 20 images with exposure time 0.4s with no filter.

* Cameras: SBIG ST8-XME (main scope LX200(bottom one)), SBIG-ST8300M(monochromatic)
* Star Alignement: on remote: Mode --, use arrows to move telescope until can see star over top of barrel without seeing barrel. Target: Betelgeuse, speed 9
* generated Maxim dl, connected both cameras, set exposure time to 0.1s
* set to speed 5, center
* start exposure, bin 4, continuous, center object, speed 3
* adjust focus, unlock primary mirror clockwise 2 revolutions, bracketing process(see how the object is changing), object keeps moving, brightness changes, focus as much as possible, center it again speed 3, synchronize-object,star,named, click for 2 sec
* observede diffraction pattern- something is wrong with the camera, filter plate not moving, adjusting, fixed filter changing
* change exposure time to 0.3s, get star off center, focus on other, dimmer stars, adjust focus once more to see clearly
* discovered diffraction pattern in filter image
* took apart camera with help of Prof Boogert
* once camera filter in working condition, resumed observation
* took exposures of far field stars near Betelgeuse in order to focus the telescope
* shifted focus to plaidees - Atlas and Cleo
* used Astrometry in order to determine our location in the night sky
* once Atlas and Cleo found, took 0.1 interval exposures from 1 to 5 seconds until stars were saturating pixel value
* once pixel values saturated, shifted view to m41 orions nebula
* took one 7 second exposure

15/2/18 Began: 17:30
Started up telescope & opened observatory. Connected to camera with maximdl (disabled camera 2), turned on cooler to -15.
Found Capella @ LST=3:45, h= 22:27, rotated telescope mount. Changed declination to 46 degrees. Located star in viewfinder.
Began continuous 0.1s 4x4 binning image capture of CCD view. Moved telescope (speed 1) opposite to image view due to CCD being upside down, to centre Capella.
Go-to button used, caused telescope to move way off target. Recallibrating as a result. Now LST=4:15, so h = 22:57, relocated Capella. Centered etc.
With LST 4:27, Atlas found at h=0:32. dec 24 deg 6 min.
Used astrometry.net to work out stars from unknown image 1, located area in stellarium
Moved to bright stars (i.e atlas and pleione), checked again with astrometry and stellarium. Synced to Pleione HIP 17851 SAO 76229 on both telescope and stellarium (connected to telescope)
Centred on Pleione. Tested stellarium movement to other stars.
Centred on Atlas, took multiple images at several exposure times, saturating the image individually for both bright stars.
zeroed telescope, closed up dome.
Finished 20:00

Attempt to check filters are moving, interrupted by cloud at blue.
Luminance - 1.5s
Red - 1.5s
Green - 3.0s
Blue???
Intermittent cloud - gotten blue, readjusted red and luminance
Blue = 1.5s
Red = 2s
Luminance = 0.5s
Gotten 20 x blue, 24 x green - some cloud though...

Logbook for PH3010 Solar limb darkening mini-project, initial setup meeting
Present: DB, MA, JC, HS
Order of tasks for observation of the sun:
1) DO NOT STARE DIRECTLY AT SUN. DO NOT POINT UNPROTECTED TELESCOPE AT SUN
2) Go outside dome and check that sun will not be obscured by the tree, wind thingy. If it will be, will have to wait before able to take images of sun
3) Check solar filters are not damaged. Fit solar filters to main scope (and if using finder scope, fit solar filter to that). Fit CCTV lens to camera, camera to filters, filters to telescope.
4) Open dome, move opening so that allows shadow of telescope to be seen on dome wall
5) Use the shadow of the top scope (the one secured by two sets of three prongs) to align the telescope with the sun. When the shadows from both sets of prongs overlap, the telescope is (roughly) aligned with the sun
6) If using finder scope, use to target edge of sun.
7) Use IC Capture program to view camera feed (really need to jam the cable into the back of the camera to get the pc to detect it). In device-properties can control gain and exposure settings
8) Use live camera feed to target edge of sun and focus (unlock and use know on back of telescope)
9) Change declination of telescope and monitor live camera feed. Need to find centre-line of sun. This is when any change in declination results in the suns edge moving out of frame (away from centre, only changing declination in one direction will move it out of frame - the other will move it more in frame)
10) On telescope control setup-targets-terrestrial or astronomical
terrestrial will keep telescope at fixed angle, astronomical follows objects through the sky
11) Choose filter to image with. Point telescope as closely as possible to centre of sun and view image histogram. Adjust and exposure until the image is not fully saturating (has a narrow yellow bar - the zero readings - visible) but has as full a range of values as practical.
12) Return telescope to point at edge of sun, in the centre. In IC capture go to the timed capture settings. Choose an appropriate target folder and image capture filenames, set the image type to bmp, turn the 'auto display capture' to off and set an appropriate capture interval and number of captures.
Note: Sun subtends an angle of about 0.5 degrees. Previous years have taken 405 seconds worth of images for this project.
13) capture images. Repeat step 11 onwards for another filter

* Dome entered 10am. Present: MA, JC, HS, supervised by Dr. DB
* Telescope cover removed, solar filters put on
* camera and colour filters were already attached to telescope. setup checked just to be sure
* Telescope setup reviewed+approved by DB
* Dome doors opened, telescope turned on
* Moon was still visible in sky - dome doors moved to allow viewing of it
* Moon used for focus (coarse and fine), took a couple of images of nice craters
* Moon found by (roughly) lining it up with the telescope, then with the finder scope, then with the camera image
* Dome doors moved to allow viewing of sun, telescope slewed to find sun
* telescope shadow aligned on wall behind telescope
* telescope moved to bring the two rows of knobs into alignment (i.e. telescope pointing at sun)
* Using camera feed, approximate equator of sun found at one edge
* Test images taken
* Moon and test sun images stored in focus_images folder
* Colour image sets taken.
* All image sets performed by pointing telescope ahead of suns motion and switching to terrestrial mode - motion of sun across sky then carries sun across the frame of view.
* All image sets taken over 3 minutes 10 seconds. This time determined by timing a test run of the method.
* 1 image per second taken for the length of the image set.
* Used maximum gain for all image sets. Exposure determined by manually slewing across the sun and trialling different exposures. Aim was to get as close to having maximum pixel values in the image, without actually having any maxed out pixels
* Where necessary, solar eclipse glasses were used to directly view sun e.g. to determine if clouds were obstructing the sun, or just the area around it
* Clear Filter 1:
* Gain 799, exposure 1/1000 seconds
* trees obstructing parts of image set - produces obvious errors in dataset
* Clear Filter 2:
* Gain 1023, exposure 1/4000 seconds
* Blue Filter 1
* Gain 1023, exposure 1/154 seconds
* Some obstruction of sun by clouds
* Blue Filter 2
* Gain 1023, exposure 1/154 seconds
* Still some clouds, but far fewer than with Blue Filter 1
* Green Filter 1
* Gain 1023, exposure 1/308 seconds
* Lots of clouds
* Green 2
* Gain 1023, exposure 1/308 seconds
* Even more clouds
* Red 1
* Gain 1023, exposure 1/1241 seconds
* A few false starts (so the file indexing is messed up), but managed to get a good run of images
* Was not able to perform another run with the green filter, due to increasing cloud cover
* Dome doors repositioned above door to roof and closed.
* Solar filter removed and lens cap replaced. Filter stored back in its home.
* Telescope returned to 0h0d
* NOTE: Minor mix-up with imgae file names. All image sets are stored in the appropriate folders / .zips for the colour filter used, but the some image sets use the wrong colour name in the individual image filenames. Recommend handling image sets carefully / renaming appropriately when used.

* Present JC, AD
* Began cooling at 16:45 to -12 deg C (~90%)
* Filter wheel set to Clear, Red, Green, Blue
* Centred on Capella and took GPS-fix. Encountered problem: telescope believed it was -1h RA from Capella however this offset was constant.
* Edit: This seemed to just be an issue with the coordinates read-out on the paddle.
* Centred on M35 and took 1000x0.1s exposures to focus.
* Then took 60s exposure- significant effects of moonlight on image- change target to M36 (RA/DEC: 05 37 13.8/34 09 04)
* Light pollution significantly reduced suggesting moon was indeed the source.
* took 60s and 90s exp in all filters
* moved to (RA/DEC: 05 37 31/34 07 50) and repeated.
* took dark and bias frames before finishing observation at 9:30pm.

| Created: 05 Sep 2013 22:16:19 | Last Revised: 09 Sep 2013 18:18:03 | Public.PedroPaiva | Minuit and iMinuit analysis |
*Performance (measured with Python %timeit() magic function):*
* PyMinuit: best of 3: 13.9 s per loop
* iMinuit: best of 3: 11 s per loop
*Conclusions:*
* iMinuit is easier to install than PyMinuit
* iMinuit is faster than PyMinuit
* iMinuit have more features than minuit (e.g. export to LaTeX and fake functions)
* Both detected and successfully minimized a 2D Gaussian on all the stars with same parameters
* PyMinuit "accidentely" fitted more Hot Pixels than iMinuit
* PyMinuit includes Simplex and Scan methods, which are not available on iMinuit
* PyMinuit is more stable - annoing bug in latest version cause segfault it limits, steps, ... are not set
Keep PyMinuit for now.

| "The bizarre looking ring galaxy NGC 1291 in Eridanus. These fairly rare types of galaxy are usually much fainter objects, but this one at "only" 33 million light years away is easily visible in modest size telescopes though the faint outer ring of material is much fainter than this. Its strange appearance is the likely the result of a collision with another galaxy in the distant past. 20"CDK with FLI-PL6303e camera. LRGB. L: 70mins. RGB: 5/5/10mins" - Damian Peach |
IRAS 20324+4057 is a Protostar in the Cygnus OB2 Association, 4,500 light-years (1,380 parsecs) away. This image is a composite of separate exposures acquired by the ACS instrument and the Isaac Newton Telescope. Several filters were used to sample various wavelengths. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:

After turning telescope on, it successfully received GPS signal and did not started the usual RA movement.
The Camera was connected to Python via MaximDL
Telescope and Focuser connected to Python via the POTH Hub
Coordinates in agrement between Scope, Python and Stellarium Target was set to be -0.1º RA from current telescope position and Python SlewToTarget was tested.
Telescope moved the right amount and stopped, both telescope and Python alerted when ready.
A second test was made with +0.5º RA. Also successfully. Still with small (-0.1º RA/DEC and +0.5º RA) movements, Python SlewToCoordinates was tested successfully. With the tests done, the telescope was moved to Vega via controled movements on Stellarium
Vega was inside the Camera Range, demonstrating that the Park Method works.
Vega was recentered (-0.01 on RA) and the telescope was manually synced.
During this test, movements as small as 0.003º on RA proved to have no effect whatsoever. The next step was to test the focuser and the camera.
First, while still on continuous mode of the camera, the Python-Focuser connection was tested.
Python can read the position and move the focuser. Units are steps. 1 step = 20µm Having confirmed that one can move the focuser with Python, Vega was taken out of focus to test if we could focus the star using a small
and it's Python
which can be used to generate the following plot:
During the tests, a cloud covered the target but the time was enough to show that the script still have room for improvement and can work.

*Focus movements*
* Positive -> In * Negative -> Out *Tests*
The data below have a significant experimental error associated with the not fixed measuring equipment.
Also, they can have errors related to a possible angle between the measuring equipment and the in-out axis therefore, the real value would differ by a factor of cos(theta)
*out* * move(-5000) - 1.86mm * move(-5000) - 1.80mm * move(-5000) - 1.86mm * move(-5000) - 1.81mm * move(-5000) - 1.88mm * *mean = (1.842 ± 0.031)mm* * move(-1000) - 0.31mm * move(-1000) - 0.40mm * move(-1000) - 0.44mm * move(-1000) - 0.27mm * move(-1000) - 0.45mm * *mean = (0.378 ± 0.076)mm* The out movement is coherent and 5000 steps is indeed equivalent to 5x1000 steps
This give 1 step aprox 0.37µm
*in* * move(5000) - 1.52mm * move(5000) - 1.55mm * move(5000) - 1.52mm * move(5000) - 1.48mm * move(5000) - 1.57mm * *mean = (1.528 ± 0.031)mm* * move(1000) - 0.21mm * move(1000) - 0.20mm * move(1000) - 0.15mm * move(1000) - 0.30mm * move(1000) - 0.18mm * *mean = (0.208 ± 0.050)mm* The in movement is 25 to 50% smaller than the out movement (depending on the movement size) with larger movements closer to the equivalent out.
This give 1 step being between 0.2 and 0.3µm *Conclusions*
The execution of the above movements led to the following conclusions: * Focuser always finishes in a 'in-movement' (e.g. asking to move out will make the focuser goes more than needed and come back about 1mm)
* This causes the isMoving check to return before the focus being ready. * Focuser limit less than aprox 30k steps when going in.
* When close to the limit, focuser will overstep (move(5000) caused the focuser to move 2.76mm) * Focuser isn't ready when isMoving returns False.
* There's a time gap when a second comand will be accepted but not executed. __Back to:__ [[Public.LogBooks][LogBooks]]

---------+++ Using a Bahtinov mask to find the focus: Based on Laurie's idea and [[http://starryvistas.net/articles/focusmask/focusmask.aspx][this article]] a set of 144 images were taken.
3 images for each of the 48 moves made by the focuser. All the movements were 'in' moves of 250 steps.
The images had a 5s exposure time and a master dark (made of 10 dark) was made and reduced from the images.
On each image, a gaussian was fitted to the brightest star (142/144 success) and the amplitude and sigma median were taken for each set of 3 images per focuser position. The data was then plotted and assumed to be in a quadratic form. The results can be seen on the images below.
For the Sigma X values, the minimum can be found at: 4841 steps
While Sigma Y minimum is at: 5411 steps
And the Amplitude maximum at: 6804 steps
According to [[LogBookAstronomyEntry0015]], the 2000 step (aprox 600µm) difference would be more than double the depth of field for the telescope [[http://starizona.com/acb/ccd/advtheoryfoc.aspx][(287µm on a f/10)]].
A visual analysis of the graphs would suggest a minimum and a maximum for Sigma Y and the Amplitude close to 6000 steps and, visually, the image at step 5750 (image set 23) is the sharpest presenting a nice 'X' diffraction pattern produced by the Bahtinov mask. __Back to:__ [[Public.LogBooks][LogBooks]] * Animation showing star going into and out of focus (with Bahtinov mask):

---------+++ Activity Log
* Took off cover for telescope & Camera, no water from last nights down pour
* Turned on Camera and followed steps detailed [[Students.UnderGraduates.RyanChealeCameraTechnicalAspects][here]]
* Set temperature to -5 deg C, waited 30 - 40 mins for stable temperature
* Used Autosave Sequence located at 'Desktop/Data/20131016_RC/25darks60s.seq'
* Autosave feature allows running of each permutation whilst saving automatically
* Data files have a different file name type than 16/10/13 due to the autosave feature, now in format T-tt.t - NNN - Eeeee.fit where T - temperature, t - temperature value, N - repetition (==20) , E - Exposure, e- Exposure time value (0.1s, 1s, 5s, 10s, 60s, 180s)
* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* Attempted Installation of Python Canopy on personal laptop to begin data analysis but fails to install on Windows 8.0 (Attempting update to 8.1 to see if it rectifies issue) [Installed 32 bit version instead]
* Set temperature value to -07.5 deg C, left for 30 - 40 mins to stabalise.
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* For data analysis will need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.

---------+++ Activity Log
* Took off cover for telescope & Camera, no water from last nights down pour
* Turned on Camera and followed steps detailed [[Students.UnderGraduates.RyanChealeCameraTechnicalAspects][here]]
* Set temperature to -5 deg C, waited 30 - 40 mins for stable temperature
* Used Autosave Sequence located at 'Desktop/Data/20131016_RC/25darks60s.seq'
* Autosave feature allows running of each permutation whilst saving automatically
* Data files have a different file name type than 16/10/13 due to the autosave feature, now in format T-tt.t - NNN - Eeeee.fit where T - temperature, t - temperature value, N - repetition (==20) , E - Exposure, e- Exposure time value (0.1s, 1s, 5s, 10s, 60s, 180s)
* File names chosen to be like this so that it's easily identifable what the file contains (i.e T-05.0-001-E0001.fit is temp of -05.0 deg, caputure #1 exposure of 0.1s
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* Attempted Installation of Python Canopy on personal laptop to begin data analysis but fails to install on Windows 8.0 (Attempting update to 8.1 to see if it rectifies issue) [Installed 32 bit version instead]
* Set temperature value to -07.5 deg C, left for 30 - 40 mins to stabalise.
* Submitted Data obtained to [[Public.LogBookAstronomyEntry0020][Dark Log Book 23/10/13]] as a record for files
* For data analysis will need to change [[Public.LogBookAstronomyEntry0017][Dark Log Book 16/10/13]] file names so that they match that of the autosaves output files for easy file name reading.

Finish taking dark frames for temperature of -10 degrees
Note: Error it temperature is +or- 0.2 degrees
Cooled down from T = 20degrees to T = -10 degrees within 5minutes - waited 30mins before taking data to ensure temperature was correct.
Exposure times 0.1s, 1s, 5s, 10s, 60s, 180s
Using Autosave feature to speed up process, Hence file format has changed to: T-10.0-001-E0001
Must go back to data taken on the 18/10/2013 and rename files for consistancy -> Done.
Proceeded to take another 120 dark frames at -7.5 degrees, as with coolers on 100% sensor temp would not go below -10.6 degrees.
Proceeded to take anothe 120 dark frames at -2.5 degrees.
CCD will then be reset to 0 degrees, and frames will be taken every 30 seconds as it is cooled from 0 to -10 degrees. The exposure time will be 2 seconds. Due to lack of time this will be postponed until next week.

---------+ Project meeting on 24 / 10 /2013
Present: Chris Haynes, Paul Hallam, Ryan Cheale, Dr Boogert, Professor Cowan.
Continued discussion on taking and analysis of dark frames.
Due to the dome not being cold enough during the day, it is difficult to cool the camera down to -15 or -20 celcius. Therefore, the remaining readings will be taken further into winter, when the dome is colder.
Objectives for analysis of dark frames:
* Plot a histogram of the -5°C, 60 second frame and compute the mean, median and standard deviation.
* Plot the column mean and consider the standard deviation for all columns.
* Plot the standard deviation as the square root of the mean and check to see if it's a Poisson Distribution.
Additionally, we should think about the dark current rate (the rate at which an electric current is generated in the chip due to the production of electrons and holes) and how to compensate for it.
We should also consider what the faintest star we could detect would be, looking at the point spread function of our telescope.

A study into the variation of background pixel count with temperature.
Initial CCD temperature was recorded to be 18 degrees. Coolers were turned on and CCD cooled to 0 degrees over the course of an hour, to ensure the entirety of the CCD began at zero degrees for the following study.
Coolers were then set to cool the CCD to -10 degrees, and one second exposures were to be taken every 30 seconds for one hour over this cool down period.
The data shall be saved in the following format: Cooler_Study-001E001
Also this shall also provide 29s exposures between the 1s exposures, which shall appear like this: Cooler_Study-001E029. This data will not be analysed.
When this collection of data has been finished, CCD was at a constant -10 degrees. The CCD coolers were switched off, and the CCD warmed back up to room temperature. Using the same method, one second exposures was taken every 30 seconds for one hour over this period.
The data shall be saved in the following format: Cooler_Study_2-001E001
Again this will also produce data that will not be analysed, in the form of: Cooler_Study_2-001E029
Room temperature in this case is 25.6 degrees.

Initial CCD temperature was recorded to be 18 degrees. Coolers were turned on and CCD cooled to 0 degrees over the course of an hour, to ensure the entirety of the CCD began at zero degrees for the following study.
Coolers were then set to cool the CCD to -10 degrees, and one second exposures were to be taken every 30 seconds for one hour over this cool down period.
The data shall be saved in the following format: Cooler_Study-001E001
Also this shall also provide 29s exposures between the 1s exposures, which shall appear like this: Cooler_Study-001E029. This data will not be analysed.
When this collection of data has been finished, CCD was at a constant -10 degrees. The CCD coolers were switched off, and the CCD warmed back up to room temperature. Using the same method, one second exposures was taken every 30 seconds for one hour over this period.
The data shall be saved in the following format: Cooler_Study_2-001E001
Again this will also produce data that will not be analysed, in the form of: Cooler_Study_2-001E029
Room temperature in this case is 25.6 degrees.

---------+++ Telescope Set Up
* Target Delta Cephei selected using Stellarium and AAVSO catalogs
* Open shutters (ropes, pull apart, tie off ropes, motor control
* Turn power on
* Press power switch on telescope
* Removelens caps
* Point towards Vega
* Line up with finer scope
* Take continuous frames 0.1s
* Center Vega in frame
* Synchronise Vega with Maxim DL and Stellarium
---------+++ Target Information
* Pulsating Variable star, magnitude variation 3.5 - 4.4, Δm = 0.9
* Period 5.4 days
* Next maximum, 07/12/2013, 9:32
* RA: 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From simulated light curve - expected Δm(max) = 0.26, expected Δm(min) = 0.01
* From light curve of Delta Cephei, and time of next maximum, we believe the magnitude should be decreasing
* Companion star HIP 110988 used as a reference star
---------+++ Initial Observation of Delta Cephei
* Centered on Delta Cephei - did not use Stellarium as could move telescope through the pole
* Frames were taken using different filters, initial exposure times:
* No filters - 1s
* Blue filter - 10s
* Green filter - 3s
* Red filter - 3s
* Took sample frames using this-set up, max pixel count was found using Python
* Re-evaluate exposure time to ensure max pixel count was in the range 55000 - 60000
* Re-evaluated exposure times:
* Focus filter - 1.1s
* No filter - 1s
* Blue filter - 10s
* Green filter - 5.1s
* Red filter - 3.3s
* Decided to take 5 repeats for each of these, and 10 repeats for Dark and Bias frames
* Autosave feature was used to take a sample set of data
* Residual image of Star found on Dark frames - low pixel count
* Implemented a 'Trash' frame before the Dark frame to attempt to remove this -> some residual image still remained
---------+++ Observation of Delta Cephei
* Autosave feature took approximately 10 - 15 minutes to run
* Approximately three runs were taken per hour
* Delta Cephei was observed for 5 - 6 hours
---------+++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope
* Turn off camera
* Turn off telescope
* Put cover back on camera
* Close dome shutters
* Turn off PC monitors

20140213 LN
Reasonably clear and forecast to be good. Worth a try to get some practice in.
* CCD at -15oC
* Aligned to capella - very high in sky.
* Went down from 46 to 37 DE to theta_aur as capella saturates the camera.
* Take subframes to practice focussing. Recorded 400 frames of theat_aur for analysis later. SNR is good as super bright. Peak around 30000 ADU. Jumps around A LOT so will have to align by centroid. Then can have a look at PSF.
* Exposure 0.1s
* 300 exposures recorded in 10m12s
* 400 exposures recorded in 13m37s *Sat bhatinov mask carefully on front of scope. Recorded 50 images with same setup as before. Not so clear.
* Exposure 0.5s
* Not so clear. Pattern seems very small indeed on CCD compared to internet images. Collimation is definitely poor and its windy so don't expect it to be great. Anyway, reasonably good in focus.
* Having a look at the Pleiades. Too extended to see anything nice and certainly with the seeing. The stars are very bright and the nebulosity not so, so quite hard to observe under these conditions.
* Imaged Andromeda ok. 30s exposures.

---------++ Telescope Set Up
* Telescope was already set up due to an earlier observation.
* Telescope centred on target Delta Cephei using Stellarium to locate coordinates.
---------++ Target Information
* RA 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From Stellarium date of next maximum is 25/02/2014
* Companion Star HIP110988 used as a reference star.
---------++ Observation of Delta Cephei
* Frames were taken with different filters and exposure times, as in Log Book 0029
* Focus filter - 1.1s
* No filter - 1s
* Blue filter 10s
* Green filter - 5.1s
* Red filter 3.3s
* 5 Repeats were taken of each.
* 10 Dark and bias frames were also taken, with an exposure time of 10s
* Trash frame taken before first dark frame.
* Three sets of observations were recorded, dc1, dc2 and dc3, using the autosave feature defined in Log Book 0029
* Due to cloud, pixel count was lower than in previous observations, however the same exposure time was used for speed and consistancy
* Each observation took approximately 10-15 minutes to run.
* Due to cloud, observation dc2 provided little to no images of delta cephei
* Waited 10 -15 minutes for cloud to clear before observaton dc3 began.
---------++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope

---------++ Telescope Set Up
* Telescope was already set up due to an earlier observation.
* Telescope centred on target Delta Cephei using Stellarium to locate coordinates.
---------++ Target Information
* RA 22h, 29min, 41s, Dec: 58deg, 29', 12"
* From Stellarium date of next maximum is 25/02/2014
* Companion Star HIP110988 used as a reference star.
---------++ Observation of Delta Cephei
* Frames were taken with different filters and exposure times, as in Log Book 0029
* Focus filter - 1.1s
* No filter - 1s
* Blue filter 10s
* Green filter - 5.1s
* Red filter 3.3s
* 5 Repeats were taken of each.
* 10 Dark and bias frames were also taken, with an exposure time of 10s
* Trash frame taken before first dark frame.
* Three sets of observations were recorded, dc1, dc2 and dc3, using the autosave feature defined in Log Book 0029
* Due to cloud, pixel count was lower than in previous observations, however the same exposure time was used for speed and consistancy
* Each observation took approximately 10-15 minutes to run.
* Due to cloud, observation dc2 provided little to no images of delta cephei
* Waited 10 -15 minutes for cloud to clear before observaton dc3 began.
---------++ Telescope Pack Up
* Turn off coolers
* Disconnect Camera
* Disconnect Stellarium and Maxim DL
* Put lens cap on telescope
* Turn off camera
* Turn off telescope
* Put cover back on camera
* Close dome shutters
* Turn off PC monitors
* Turn off lights and leave dome

---------++ Telescope Set Up
* Telescope was already set up due to an earlier observation.
* Delta Cephei located using Stellarium
* Telescope Centred on Delta Cephei
---------++ Observation of Delta Cephei
* From Stellarium Delta Cephei was at maximum at 21:25:00 during this observation (25/02/2014)
* Frames were taken using different filters and exposure times
* Unlike previous observations images were near saturation at original exposure times, as a result the exposure times were lowered to 0.72 of the original.
* This provided the following exposure times:
* Focus Filter = 0.8s
* No Filter = 0.7s
* Blue Filter = 7.2s
* Green Filter = 3.7s
* Red Filter = 2.4s
* 5 Repeats were taken of each
* 10 Dark and Bias frames were also taken with 10s exposure, in addition to a trash frame before the first dark.
* Only one set of observations, dc1, was recorded due to approaching cloud.
* Observation saved to Desktop/Data/20140225_PH

Using the spectrometer to find the brightest spectral line in mercury and Find the best micrometer reading for the angle of the camera.
Camera was ST-7E, Setup SBIG Universal.
Temperature for all the images was -6.5 deg C.
*Focus*
Exposure time: 0.1s; Grating distance 1.814mm; Camera angle micrometer reading 2.495 (heavily sloped)
Used continuous range to find a reasonable staring point.
Used range of 18mm to 20.5 mm in steps of 0.5
Reduced range to 19mm to 20.5mm in steps of 0.10
Reduced range further to 19.50mm to 19.80mm in steps of 0.05
*Camera Angle*
Exposure time: 0.1s; Grating distance 1.814mm; Focus distance was 19.60mm for this
Used continuous range to find staring point.
Used range of 2.50mm to 5.50mm in increments of 0.5mm to start.
Reduced range to 4.00mm to 5.00mm in steps of 0.10mm
Reduced range further to 4.45mm to 4.65mm in steps of 0.05mm
Found the best angle to be _4.60mm_
*Brightest Peak Data*
Looking through the spectrum the brightest peak, found at 4.00mm in grating micrometer.
This was saturated so the lamp was moved back by 5cm which was still saturated, then we moved it back by another 5cm which put the lamp back from the optical fibre by 25cm. This reduced saturation where refocus was done. Seemed to saturate at 50,000 confirming it was brightest peak.
Used this to check the focus and recalculate.
used a range from 19.50mm to 20.50mm in steps of 0.10mm
Found best focus distance on micrometer to be _20.10mm_

Used range of 18mm to 20.5 mm in steps of 0.5
Reduced range to 19mm to 20.5mm in steps of 0.10
Reduced range further to 19.50mm to 19.80mm in steps of 0.05
*Camera Angle*
Exposure time: 0.1s; Grating distance 1.814mm; Focus distance was 19.60mm for this
Used continuous range to find staring point.
Used range of 2.50mm to 5.50mm in increments of 0.5mm to start.
Reduced range to 4.00mm to 5.00mm in steps of 0.10mm
Reduced range further to 4.45mm to 4.65mm in steps of 0.05mm
Found the best angle to be _4.60mm_
*Brightest Peak Data*
Looking through the spectrum the brightest peak, found at 4.00mm in grating micrometer.
This was saturated so the lamp was moved back by 5cm which was still saturated, then we moved it back by another 5cm which put the lamp back from the optical fibre by 25cm. This reduced saturation where refocus was done. Seemed to saturate at 50,000 confirming it was brightest peak.
Used this to check the focus and recalculate.
used a range from 19.50mm to 20.50mm in steps of 0.10mm
Found best focus distance on micrometer to be _20.10mm_

27th Oct 2014 Msc Observation.
*Begun:* 18:30
*Finished:* 22:30
Conditions: Mostly clear, a little muggy. No cloud coverage.
Begun observation session with a run down of the procedure to prepare the dome.
*Dome Procedure:*
-
Enter dome
- Close the hatch to prevent heat rising and entering the dome. The floors beneath are heated which causes a ‘chimney’ like effect if the hatch is left open as the hot air from below will rise up through it. Ideally the scope and dome should remain cool so noise due to thermal fluctuations is kept to a minimum.
- In the Maxim DL suiteconnect to the telescope. This allows control of the camera for example you can set exposure times and capture images from the program.
- Enable the CCD cooler in Maxim. This should be done ~1 hour before taking exposures. If you take observations too soon after enabling the cooler you get a ring like effect on your observations around the outer area of the frame. The ring progresses further to the sides of the frame as the CCD cools until it eventually disappears.The set-point of the cooler is set to -10 degrees celcius and the CCD itself fluctuated around this point slightly once the cooler had taken full effect.
- Untie the ropes that control the shutter of the dome. Pull on ropes to open the shutter of dome, if the shutters do not open with ease, there is a long stick with a metal prod at one end which can be used to manually push the shutters open from near the top of the dome.
- Once shutter is open, tie the ropes off again to make sure that they are kept out the way of the moving parts of the done which can rotate bothe counter and clock-wise
- Using the door on side of dome, go outside and do some preliminary naked eye observations to find an interesting object to observe (this is important for aligning the telescope as detailed later on). This allows you to plan roughly where the telescope and open shutter should be pointing to allow unrestricted viewing.
- Using the dome control unit, align the dome opening with what you want to observe.
- When finished observing, realign both the dome and telescope to their origional position. Close the dome shutters and tie up the ropes.
- *Telescope Alignment:*
-
Use a high speed on the control paddle (speed button -> 9 is fastest, 1 is slowest on number pad) to crudely align the scope with what you want to observe using the arrow buttons. This can be done roughly by eye by lining up the two bolts on the side of the telescope with what you are looking for.
- Then use the viewfinder which has a set of crosshairs to align the scope more accurately with the object in the sky. A medium speed setting on the paddle can be used to move the scope with a greater deal of precision.
- Once the crosshairs are centred on the object you wish to view, take an exposure in the maxim DL suite. Once the image has been taken and downloaded you can adjust the scope to get the object centred in the frame. If you set maxim DL to take continuous ~1s exposures you can get a better sense of the best way to align scope and object.
- Once the scope is aligned, enable GPS lock. This continuously corrects the scope to account for the rotation of the earth. The field of view of the scope is very narrow causing the object you are observing to move through the frame if the scope remains stationary.
- Once tracking is enabled, the scope should keep the object you are trying to view in frame automatically.
- Using the control paddle, tell the telescope which star/object it is currently aligned to
- With the telescope connected to stellarium which now allows you to control the scope through the program itself. Using the star charts, you can align the scope to stars/objects shown in stelarrium. (Wait for the ‘beep’ if you move the scope in the program. The scope moves quickly at first but then makes finer corrections to ensure the scope is aligned well. The 'beep' occurs once the telescope is properly aligned, it can take some time ~20-30 secs).
- While repositioning the telescope it is important to be aware of it's orientation with respect to it's base. The telescope is capable of flipping over on itself which can cause the CCD attatchment to collide with the stand. In a situation where this may happen, power down the telescope via the power controls located on its stand immediately.

8th December Observatins
Start time 18:00
Conditions: Varied from good and clear to a little hazy which had an effect on exposures.
Observations:
Deneb (alpha cyg):
Used for alignment and tracking purposes
Magnitude - 1.25
CCD cooler hadn't been running long so visible ring present.
M39 open cluster:
Magnitude - 4.60
Worked with Focuser Max to explore the effects of being out of focus. Varied focus by +-5000 of origional position to see effects of being too out of focus (stars take on donut like shape). Fine tuning steps of 500 were taken in and out of focus to produce a sharper image. Took multiple exposures (attatched to this post).
Images taken:
1 image with an exposure time of 1 second
1 image with an exposure time of 10 seconds
1 image deliberately out of focus with an exposure time of 10 seconds
10 images with an exposure time of 15 seconds 10 images with an exposure time of 25 seconds
*Crab Nebula, M1:* Abberations due to dust particles on the telescope can be noticed in the images. They manifest as donut shapes with dark rings and brighter centres.Tracking errors in longer exposures noticable in some frames. Images Taken: 1 image with an exposure time of 20 seconds 1 image with an exposure time of 60 seconds 5 images with an exposure time of 90 seconds *Orion Nebula:* 1 im age with an exposure time of 5 seconds 1 image with an exposure time of 10 seconds 20 images with an exposure time of 1 second 10 images with an exposure time of 5 seconds *Pleiades, M45:* Visible with the naked eye. Images Taken: 1 images with an exposure time of 15 seconds 5 images with an exposure time of 10 seconds *Jupiter:* Visible with the naked eye. It's moons were visible through the viewfinder and were imaged. Seperate images of jupiter itself and two visible moons were taken for possible compositie image construction. Jupiter was very bright in the nightsky. Images Taken: 1 image with an exposure time of 0.1 second 20 images with an exposure time of 0.1 seconds of the moons

*Observations of the Spectrum of Betelgeuse*
Started looking at Capella. Using a small sheet of tracing paper to allign the star in the optic fibre coupling. With Capella at a high Altitude we switched to Betelgeuse as a target to make allignment easier.
Viewed Capella at
5hrs 20' 30'' RA
45deg 8' 2'' DEC
with the micrometer at Grating-4mm, Angle-3.25mm, Focus 20.2mm.
changed the RA 5'' either side to align it centrally while observing the intensity recieved.
*Betelgeuse*
Next look at Betelgeuse,
5hrs 58' 32' RA
6deg 25' 30'' DEC
Took a 30s exposure at 4mm to look at the spectrum as best as possible. Then took 60s exposures of Betelgeuse between 0mm and 10mm in steps of 0.5mm.
After Betelgeuse we briefly moved to the Orion nebula however it was too dim to observe.
*Pollux*
7hrs 46' 14'' RA
27deg 59' 18'' DEC
Again took 60s exposures from 0mm on the grating position micrometer too 10mm in steps of 0.5mm.
Laurie left at 23:00
*Castor*
7hrs 35' 22'' RA
31deg 51' 40'' DEC
60s exposure from 0mm too 5mm in steps of 0.5mm

Please edit and put your text etc. here
Start Time: 19:00
Conditions: Slightly cloudy at start, quickly became clear around 8pm and remained clear.
Observations:
*Castor (Alpha Gem)*
Aligned to Castor, RA: 7h 34m 35.87s, Dec: 31dg 53' 17.82" Apparent Mag: 1.93
Ring visible due to cooling of CCD chip taking place.
*Near Castor*
Observed multiple stars near Castor with low magnitude (10 - 15)
No images taken.
Ring still visible.
*NGC2388*
Centred on galaxy NGC2388, Apparent Mag: 14.
NGC2388 was chosen as a target as it is known to currently contain a Supernaova of Apparent Magnitude 15. See http://www.rochesterastronomy.org/snimages/snactive.html
Supernovae: PSN J07285387+3349106, RA: 07:28:53.87, Dec: +33:49:10.6, z = 0.013790
One frame was taken at 120s exposure. Stars were cross checked with Stellarium and were found to be low magnitude (10-16). Two other galaxies were also clearly visible, NGC2385 and NGC2389. The cooling ring was still visible at the edges of the frame. This location was chosen for the target of this observation due to the number of low magnitude stars, and the presence of three galaxies.
Uploaded a frame to astrometry.net
Experimented with 180s exposure, decided to use 120s.
Stacked frames using MaximDL built in image stacker to invstigate noise reduction.
Images taken:
Data was taken in bursts of 9 images, 3 Light Frames with 120s exposure, 3 Dark Frames at 120s exposure and 3 Bias frames.
Dome was realigned every 2 bursts to ensure unobstructed view of the sky.

---------+ 2015 05 20 LN DSLR Observation
* Trying out DSLR on back of scope
* Benefit - easy live video to investigate focussing, wide field of view
---------++ 20:30 start
* Dismounted SBIG camera (in case)
* Canon DSLR bayonet adapter + BADER 2" - T/2 Nosepiece on back of micro-focuser
* Observed Moon, Venus & Jupiter during twilight ~ 21:40
* Aligned & synchronised to artturus star to the south as visible to the naked eye
* image of M3 globular cluster ~ magnitude 6 - can make out ok in photos but still blue sky background as still slightly light
* 2155
* Trial of Deep sky object - still lightish but will keep iterating over objects
* Bodes Nebula mag 6.9
* Of note is that the DSLR is slim enough for a polar flip of the mount. Haven't, but can.
* Whirlpool Galaxy
* Getting better images but can only really see core of galaxy - still to much sky glow
From images of a single bright star or say of Jupiter and it's moons, you can see what appears to be both coma and chromatic aberration. The edges of non-point like objects have an orange tinge on one side and a blueish tinge on the other. Jupiter is relatively low just now so there is a strong affect from the atmosphere / imaging but still Jupiter had an asymmetric tinge. The moons were also quite distorted. Although the 'live view' gives you some indication, it simulates the exposure settings and can distort the image a little. Best to take images directly and zoom in to compare. Not too different from live view though.
* Telescope likely needs collimation, but the trouble is finding a good enough night for to be able to observe any improvement.
Sky much darker now. While no clouds around, there is a bit of haze - can't see huge multitude of stars.
* Starting at 3845 images of great cluster in hercules.
Finish at 22:20

---------++ *Before taking data*
* Time of turn on: 18.20.
* Cooler set to -7 degrees.
* Temp at -6.9 degrees at 18.30.
* Center the telescope on Vega.
* Aling the telescope to Vega. (~Mode on the controller)
* Speed 5 and later 3 on controller while focusing on Vega.
* Microfocuser used to fine focus.
* Speed 3 to place Vega in the center of the image.
---------+++ Alpha Persei Cluster (Cr 39, Mel 20)
* We chose our cluster as the Alpha Persei cluster.
* To focus on the cluster we chose a nearby bright star Mirphak.
* We used it to correct our ofocusing and we synched Stellarium wityh the telescope.
* We choice a patch of the cluster (HIP16001) and took 10 vimages of 10 second exposures. ( x binning set to 1, x anmd y originally inverted, this was reversed)
* 5 bias frames and dark frames of 5 1min exposure.
* Took 3 40 s red.
* Took 3 40-s gtreen.
* Took 3 90 s blue.
*
* Move to a different patch (around RA:3h29min29s, DEC:49deg44'16")
* Ian joined us at 20:00
* 3 images of 60s visual.
* 3 images of 120s red.
* 3 images of 120s green.
* Finished taking data at 8.30 pm.
---------+++ Dark and bias frames
* Started taking dark frames. 5 images of 120s.
* Take 10 bias aswell.
Observation finished at 8.56pm.

Started data taking at 13:20.
cooler set to -15 degrees, ambient temperature 8 degrees
Sequence of:
* bias, (dark) 0.1 10, 30, 60, 90, 120
* Repeated every 30 minutes.
* Took a large piece of card and evenly illuminated it in order to take flat frames. In order to investigate the cooling ring/dust. Note that if the focus is changed this will have to be repeated.
* Had to place cover on telescope for dark frames, as an illuminative effect was seen.
* Ring appeared to be gone as of 15:10, took 01:50 taken to disappear.
* Bright border remains after above time.
* at 15:20 started taking 1 second dark and flat frames.
* 15:50 began taking master bias, dark and flat frames.
* *Joined by Claire at 17:00*
* We started observing at6pm
* We went Procyon and aligned the telescope using it.
* We looked at the Beehive cluster but there were not enough stars.
* We chose M39 cluster.
* Taaking images in no, red, blue, green, luminance filters.
* No filter: 60 sec exposure
* Red filter: bad target

Started data taking at 13:20.
cooler set to -15 degrees, ambient temperature 8 degrees
Sequence of:
* bias, (dark) 0.1 10, 30, 60, 90, 120
* Repeated every 30 minutes.
* Took a large piece of card and evenly illuminated it in order to take flat frames. In order to investigate the cooling ring/dust. Note that if the focus is changed this will have to be repeated.
* Had to place cover on telescope for dark frames, as an illuminative effect was seen.
* Ring appeared to be gone as of 15:10, took 01:50 taken to disappear.
* Bright border remains after above time.
* at 15:20 started taking 1 second dark and flat frames.
* 15:50 began taking master bias, dark and flat frames.
* *Joined by Claire at 17:00*
* We started observing at6pm
* We went Procyon and aligned the telescope using it.
* We looked at the Beehive cluster but there were not enough stars.
* We chose M39 cluster.
* Taaking images in no, red, blue, green, luminance filters.
* No filter: 60 sec exposure
* Red filter: bad target
* new targetr: ra: 2h43min07sec, dec:+47deg47arcmin01arcse3c

The aim of the session was to modify the parameters of the camera. Using only OpenCv it was impossible to set the camera's parameters with known units.
py-ic-imaging-control was downloaded from: https://github.com/morefigs/py-ic-imaging-control
py-ic-imaging-control is a python wrapper for the IC imaging control software development kit from the imaging source (TIS). It provides control to TIS cameras, and can serve as an alternative to using OpenCv to access the cameras parameters.

The DMK camera was fixed to a tripod and pointed at the moon.
Run1: Gain set to 180 and images were recorded of the moon at a frame rate of 7.5 frames per second. The algorithm left the exposure setting on 1 as the image was not over or under exposed on this setting.
Run2: Gain was increased to 1023. The images were over exposed and the algorithm accounted for this by changing the exposure setting in increments of 1. It was noted that this was very slow to respond to large and sudden changes in conditions.
Run3: The code was modified such that the amount the algorithm changed the exposure setting depended on the number of pixels that were saturated. This massively decreased the time the algorithm took to find the correct exposure setting. See screen shot.
Images were also taken of Orion's Nebula, see image file names for parameter settings.

Star of setup: 17.40
Cooling: -10 degrees
Weather: 50% clouds, partially clean on the studied area
SBIG ST8 XME
Target delta Cep (companion HIP110988)
Ra/Dec (on date) 22h29m57.26s
Az/Alt: 318deg 44'20''/38deg34'50''
Took testing pictures: Cooling_1 and cooling_2, can be seen a ring surrounded by the ice. Secong image shows larger ring, meaning hte camera is cooling down
Cooling_3 image is clear and even
Checked the wether with met office, clouds are exopected to clear for the rest of the night
Finding the star by eye, alighning the tescope, using stllarium found it was Procyon
As it wasn't clear that the star is Procyon, checked with Rigel
Took images of the delta cep with no filter and with filters: red, green, blue and spectroscope. Aimed for 50 000 pixel value - the closest to the maximum possible p.v.
Exposure time was increased as different filters were applied, because different filters obsurb more light.
Cloudy weather led to taking many pictures for blue filter with longer exp time, 16 sec.

---------+ Focussing Beam Splitter
* To find best focus should be able to focus onto a single fibre, once one illuminated, in focus. will have to use extension rings for optical fibre.
* CCD camera can then be adjusted until in focus.
* Focus by shifting backwards and forwards on rails.
* Find focus of camera with max intensity and minimum width of laser.
* Use diffuser or neutral density filter, will need neutral density filter.
* Make two plots of intensity on camera and fiber and adjust until peaks overlap.
* Such that there are two plots which look similar to:
---------+ Aligning Beam Splitter
* Align by moving the mirror horizontally and vertically until maximum intensity
* possibly get 3 more irises, to control aperture at camera, fibre and entry, to make sure always have good alignment.
* As now in focus, can scan around fibres and find the relative positions compared to the end where they are arranged into line.
* This could help with finding best position of ray on camera
* Look up mirror and see how much change in angle before lost fibre, one full turn until laser out of view.
* try to get two irises as far away from each other for best alignment.
* once part for CCD arrives, move around and find relative positions on camera to positions on optical fibre.
---------+ Relating to telescope
* Have to use larger beam size so that f# is the same as the telescope, f# = 10,
* currently 3 dioptre lens, so 1/3 m focal length, this means need a beam diameter of 33.3 mm or a longer focal length.
* as , where f is the focal length, d is the diameter of beam or aperture and f# is the f number.
* consider which camera to be used.
* beam splitter reflects 30% and transmits 70% so check this.
---------+ testing intensity
* tested the intensity at reflection and transmission, with diffuser and tissue in front of laser, tissue made intensity vary substantially so averaged over five frames, the reflection intensity was found to be 3% of the transmission intensity, however there could be problems with focus and alignment at the refection, need better analysis of this.

---------+ Aligning Camera and optical fiber
* Spectrum images,
* Exposure: 0.1s
* Temp: 10 deg
* used subframes around spectral to speed up
* FireWire camera * Exposure: 1/500 s
* The FireWire camera was attached to the beam splitter and connected to IC capture
* Optical fiber was attached using a spacer to approximate the same focal length as the FireWire CCD
* Initially an approximate focus was found on the FireWire camera.
* Then the angle of the mirror was adjusted vertically such that the laser beam was scanned vertically.
* images of the position on the CCD and the spectrum were taken at a range of positions.
* The amplitude of the spectral line was then recorded with position on the CCD.
* This gave a plot shown below for the maximum intensity. i.e centre of fiber
*
* This was then repeated for a scan horizontally, which gave the plot below.
* The best positions were found to be at [190,218] pixels, i.e 190 pixels across and 218 pixels down
* The the focus of the image was to be found.
* The box which the beam splitter and camera is attached to was placed on the rails and scanned backwards and forwards using a ruler for approximate focal length.
* Images were recorded for both the camera and optical fiber, and the amplitudes were plotted against focal length.

---------+ Alignment of Camera and Optical Fiber
* SBIG camera,
* Temp: 10deg
* Exposure: 0.1s
* subframe around fibers
* FireWire Camera,
* Exposure: 1/500 s
* Took focus measurements first by moving beam splitter to find best focus.
* Best focus was found by subtraction background of spectral line image and summing pixels
* Best focus for image was found by finding max pixel value
*
* The optical fiber focussed ~6mm from the FireWire camera
* Optical fiber was adjusted such that it is as far out as possible using the smallest spacer, and the camera was adjusted so that it was as close to the beam splitter as possible.
* This was to close the 6mm gap found earlier
* The fiber and camera were then realigned as the FireWire camera will have been rotated slightly and moved out of alignment.
* Both horizontal and vertical alignment were used and the best positions were found at maximum intensity the same as for the focus.
*
---------+ Attachment of guidescope
* Two mounts for the dovetail plates attached on the top of telescope, plate then attached.
* The two dovetail plate mounts for the bottom of the telescope have to have small section removed due to bolts on the telescope which were in the way.
* Bottom dovetail plate then attached.
* guidescope rings and guidescope attached to the top plate
* counterweight attached to bottom.
* The telescope was then approximately balanced by adjusting the counterweights position on the plate and by unscrewing the counterweights so they were further from the OTA.

---------+ Alignment of fiber horizontally and vertically
* SBIG camera for spectrometer:
* Exposure: 0.1s
* Temp: 10 deg
* Subframes
* FireWire Camera:
* records video at 30fps
* Exposure: 1/500 s
* Approximate focus was first found. set at 255 mm
* The mirror was adjusted horizontally such that the laser moved horizontally in the camera frame.
* Images were then taken of both the spectral line of the laser and the image on the FireWire camera as it was scanned, 40 images were taken.
* The maximum intensity of the beam and its position were recorded on the FireWire camera and the summed intensity was recorded for the spectrum with removal of backgorund.
* The intensity on the spectral line was then plotted against the position on the FireWire camera, this gave a plot shown below.
* The peak position on the above plot is then used to set the position of the beam on the camera, which is approximately at a position of 200 pixels.
* Once the position has been set the process was repeated scanning this time vertically, this gave a plot as shown below.
* The best position for the beam to be on the camera for max intensity at this stage is then at pixel values [200,216].
---------+ Focussing the beam
* Once the beam has been set to the best position as found earlier the camera and optical fiber were adjusted between distances of 220mm-290mm in 2mm intervals to find the best focus.
* Here the same measurements as before were made. The intensity of the spectral line and the maximum intensity of the FireWire camera are plotted against focal distance.
* The plot of both the camera and optical fiber is shown below.
* With this image the approximate best focus was set at 250mm
---------+ Repeat of alignment
* The alignment process was then repeated as before, this gave the below plots.
* These gave maxima at a pixel position of [201,217], The image below shows the position of the laser of the camera at this point:
---------+ Horizontal Scans at different Focal lengths
* For 6 different focal lengths, 240,244,248,252,256,260, a horizontal scan of the laser was recored on the camera and the spectrometer. This range was chosen as in the above focus plots, this is where the intensity flattens.
* For each of these the position of the laser of the FireWire camera was plotted against the total intensity of the fibers.
* The aim was that the focal length which gives the smallest width of a spectral line is the correct focus.
* The plot below shows the intensity plot for each of the focal lengths, and the widths of the line.
* This shows the widths does not change much in that range, this could be due to the fact that the focus is smaller than the size of the optical fiber, therefore, the integrated amplitude will remain the same in this range.
* Therefore, by selecting a single fiber to integrate the intensity over, it should be possible to find focus.
* The below plot shows the same results for a single fiber
* This shows that the width of the line drops in the range of 252-256 mm .
* by fitting a Gaussian function to both the image on the firewire camera and the plots above, the widths could be plotted against the focal length for both.
* Each of these were then fit with a hyperbola function,
* This gave parameters of,
| parameter | FireWire | Fiber |
| mean | 254.8±1.2 | 255.2±1.1 |
| a | 4.28±0.92 | 6.12±1.25 |

Saqib Hussain + Jervis Ong Arrived at 16:24, weather clear
* AA arrived 17:30
* Took example flats with both cameras
* Setup telescope, synched on Vega
* focused the telescope on a star
* took a few dark frames to distinguish dust on the telescope
* Primary observation target identified : rho Cyg- 73 Cyg - HIG 106481, right ascension = 21h 33m 58.85298s, declination = 45° 35′ 29.1 "
* Checked the camera cooler temperatures: -5.2 for ST8 and -15.0 for ST8300
* Took exposures with exposure time 0.1s for ST8300 and 0.5s for ST8
* For ST8300, file names begin with odd alphabets (a,c and so on) whereas for ST8 file names begin with even alphabets
* The data is compiled as below:
| Telescope | Exposure time/s | Time frame/minutes | No.of Images | File starts with |
| ST8300 | 0.1 | 12 | 66 | a |
| ST8 | 0.5 | 12 | 45 | b |
| ST8300 | 0.1 | 16 | 100 | c |
| ST8 | 0.5 | 11 | 45 | d |
| ST8300 | 0.1 | 9 | 45 | e |
| ST8 | 0.5 | | 45 | f |
* Moved on to collate data for atmospheric extinction
* For ST8, we tried to take images with different filters (luminescence, red, green, blue) for an exposure time of 0.4s
* However, due to technical problems we were unable to take images with colour filters
* We continued taking unfiltered images every 10 minutes (as the star moved from the azimuth to the horizon), saving them as files beginning with L
* Exposure time is 0.5s for every image
* Cooling power was within the range of 40 and 49%
* Data are as follows:
| Time | File Name |
| 2158 | L1 |
| 2208 | L2 |
| 2218 | L3 |
| 2228 | L4 |
| 2238 | L5 |

| 2308 | L8 |
| 2318 | L9 |
| 2328 | L10 |
| 2338 | L11 |
* took a photo of Andromeda
* Turned the coolers off, disconnected the cameras. Double checked everything was disconnected.
* Exported data into USB stick.

Please edit and put your text etc. here
set up procedure
* check for damages on solar filters
* solar fillters on finders scope and main scope
* mount camrea
* use a SCT connector
* screw onto fliter and telescop
* RGB filter
* clip onto tube
* C-mount to 1.25 inch tube
* screw onto camera
* camera
* mount camera unto telescope by unscrewing the big ccd camera
* fire wire cable connected to the camera(clips in)
* with them, covered you can open the dome doors
* switch on telescope
things differe form a normal observation:
* use different type of camera( imaging source dmk 21af04.as)
* use a different piece of software
* stop the tracking
IC capture
* open IC capture
* click camear being used
* device properties click off auto gain and exposure
* check if histogram isnt saturated
* adjust exposure so it is not saturated
* saving sequnece of image
* capture -> squence settings
* file name and target, pick a directory(desktop/data/YYYYMMDD) -> index at 1
* file type BMP
* Automated sequence -> interval at 1 sec -> end sequence after 400 Frames
* capture -> sequence timer -> start timer
how to turn off tracking
* set up -> enter
* targets -> enter
* trestral or astonamical ->enter
we are going to be using 2016-11-02 data

Weather cloudy, intermittently clear
use DSLR to take white images to look at the natural vignetting effects of the camera, took many exposure times so to get an unsaturated image. Need to process these to get a pixel vs intensity curve to show that the fractional ratio of intensity does not depend on exposure. Also look at different colour channels and create a plot to show all 3
Then set up the telescope so as to record data, fit with sun filters and imaging source camera. Using ICcapture software.
Use shadow of the telescope to align, and adjust further with finder scope.
set telescope to the west of the sun to see it passing through the window, takes around 1min to fully pass no data recorded
Use DSLR to take images of the sun, lowering the exposure times to find an unsaturated image. Use circle finder code to analyse the intensity array across a diameter of the sun. Attached Text files show the image numbers on the DSLR for varying exposure times ISO=100 for targets of the sun then a white light source evenly lit for investigating the vignetting effect.

looking into error in blue filter images taken previously
is an error in the programme with the readout, reboots and restarts did not solve this. Updated the verison of IC Capture from 2015 model to 2017, this had some minimal effect
Look at changing the Frames Per Second to a smaller amount (from 30 to 3.75) this did correct for the oscillation problem looking at blue sky
Move to try and take images of sun again with filter

* Camera firewire connected to main telescope with solar filters attached
* Telescope turned on and GPS fix taken
* dome doors opened and dome moved to locate position of sun
* once shadow aligned with dome, position of telescope adjusted to align with sun by observing its shadow on dome wall
* position then made more accurate by viewing sun through finder scope and adjusting to centre sun on cross-hairs
* focus corrected by moving cross-hairs to edge of sun where the contrast gradient is greatest
* manual focus by unlocking and rotating focus knob
* exposure 1/5000s, gain 1023 ?
* approx. tracking time made using speed 3 (~20s)
* approx. tracking time then made in terrestrial mode (~2min15s)
* ratio: 0.148
* tracking back to astronomical and focussed back on edge of sun on speed 3, moved 20 seconds into background

start time:17:00
* Went outside located a star with coordinates (Horizon System) estimate: A = 60, a= 60-70
* Checked on Stellarium star is probably Capella A = 75, a = 52
* Turned on cameras, took off lens covers etc.
* Set telescope declination 46 deg pm 1
* Found the LST, calculated the hour angle h=LST-a, 21:57:52 rotated telescope to the hour angle
* Minor adjustments needed due to time taken in calculated h - done by eye
* Focused on Capella, overly saturated, focused as much as possible
* Clouds briefly moved in, checked the weather outside, had moved by the time of the next step but not completely clear
* Moved Capella off the screen, focusing on far-field stars
* Took picture of field stars near Capella. Image taken with 1x1 binning at 1s.

Time: 22:40 - 1:50
Targets: Betelgeuse & Pleiades Cluster in RBG filters Cameras Used: SBIG ST 8XME(camera 1) and SBIG ST-8300M(camera 2)
Both cooled to -20deg Telescope already synchronised, moved and focused on Betelgeuse. Target too bright for filters. Kept saturating. Moved to a new target, the star, Bellatrix. Again too bright for filters. Moved to another new target, HIP26594. 15 images taken for all three filters RBG, exposure time 1.5s. Then moved to the Pleiades, in narrow view camera (camera 1). We took ten images in each filter with exposure time 10s. And we took ten images in each of the green and blue filters with exposure time 40s. We switched to camera 2, a wide view that could take an image of the whole cluster. The image is inverted in camera 2. We took 20 images with exposure time 0.4s with no filter.

* Disassembled previous experiment
* Attached cameras: make sure plugged in switched on
* Cameras: SBIG ST8-XME (main scope LX200(bottom one)), SBIG-ST8300M(monochromatic)
* Star Alignement: on remote: Mode --, use arrows to move telescope until can see star over top of barrel without seeing barrel. Target: Betelgeuse, speed 9
* generated Maxim dl, connected both cameras, set exposure time to 0.1s
* set to speed 5, center
* start exposure, bin 4, continuous, center object, speed 3
* adjust focus, unlock primary mirror clockwise 2 revolutions, bracketing process(see how the object is changing), object keeps moving, brightness changes, focus as much as possible, center it again speed 3, synchronize-object,star,named, click for 2 sec

15/2/18 Began: 17:30
Started up telescope & opened observatory. Connected to camera with maximdl (disabled camera 2), turned on cooler to -15.
Found Capella @ LST=3:45, h= 22:27, rotated telescope mount. Changed declination to 46 degrees. Located star in viewfinder.
Began continuous 0.1s 4x4 binning image capture of CCD view. Moved telescope (speed 1) opposite to image view due to CCD being upside down, to centre Capella.
Go-to button used, caused telescope to move way off target. Recallibrating as a result. Now LST=4:15, so h = 22:57, relocated Capella. Centered etc.
With LST 4:27, Atlas found at h=0:32. dec 24 deg 6 min.
Used astrometry.net to work out stars from unknown image 1, located area in stellarium
Moved to bright stars (i.e atlas and pleione), checked again with astrometry and stellarium. Synced to Pleione HIP 17851 SAO 76229 on both telescope and stellarium (connected to telescope)
Centred on Pleione. Tested stellarium movement to other stars.
Centred on Atlas, took multiple images at several exposure times, saturating the image individually for both bright stars.
zeroed telescope, closed up dome.
Finished 20:00

Logbook for PH3010 Solar limb darkening mini-project, initial setup meeting
Present: DB, MA, JC, HS
Order of tasks for observation of the sun:
1) DO NOT STARE DIRECTLY AT SUN. DO NOT POINT UNPROTECTED TELESCOPE AT SUN
2) Go outside dome and check that sun will not be obscured by the tree, wind thingy. If it will be, will have to wait before able to take images of sun
3) Check solar filters are not damaged. Fit solar filters to main scope (and if using finder scope, fit solar filter to that). Fit CCTV lens to camera, camera to filters, filters to telescope.
4) Open dome, move opening so that allows shadow of telescope to be seen on dome wall
5) Use the shadow of the top scope (the one secured by two sets of three prongs) to align the telescope with the sun. When the shadows from both sets of prongs overlap, the telescope is (roughly) aligned with the sun
6) If using finder scope, use to target edge of sun.
7) Use IC Capture program to view camera feed (really need to jam the cable into the back of the camera to get the pc to detect it). In device-properties can control gain and exposure settings
8) Use live camera feed to target edge of sun and focus (unlock and use know on back of telescope)
9) Change declination of telescope and monitor live camera feed. Need to find centre-line of sun. This is when any change in declination results in the suns edge moving out of frame (away from centre, only changing declination in one direction will move it out of frame - the other will move it more in frame)
10) On telescope control setup-targets-terrestrial or astronomical
terrestrial will keep telescope at fixed angle, astronomical follows objects through the sky
11) Choose filter to image with. Point telescope as closely as possible to centre of sun and view image histogram. Adjust and exposure until the image is not fully saturating (has a narrow yellow bar - the zero readings - visible) but has as full a range of values as practical.
12) Return telescope to point at edge of sun, in the centre. In IC capture go to the timed capture settings. Choose an appropriate target folder and image capture filenames, set the image type to bmp, turn the 'auto display capture' to off and set an appropriate capture interval and number of captures.
Note: Sun subtends an angle of about 0.5 degrees. Previous years have taken 405 seconds worth of images for this project.
13) capture images. Repeat step 11 onwards for another filter

* Dome entered 10am. Present: MA, JC, HS, supervised by Dr. DB
* Telescope cover removed, solar filters put on
* camera and colour filters were already attached to telescope. setup checked just to be sure
* Telescope setup reviewed+approved by DB
* Dome doors opened, telescope turned on
* Moon was still visible in sky - dome doors moved to allow viewing of it
* Moon used for focus (coarse and fine), took a couple of images of nice craters
* Moon found by (roughly) lining it up with the telescope, then with the finder scope, then with the camera image
* Dome doors moved to allow viewing of sun, telescope slewed to find sun
* telescope shadow aligned on wall behind telescope
* telescope moved to bring the two rows of knobs into alignment (i.e. telescope pointing at sun)
* Using camera feed, approximate equator of sun found at one edge
* Test images taken
* Moon and test sun images stored in focus_images folder
* Colour image sets taken.
* All image sets performed by pointing telescope ahead of suns motion and switching to terrestrial mode - motion of sun across sky then carries sun across the frame of view.
* All image sets taken over 3 minutes 10 seconds. This time determined by timing a test run of the method.
* 1 image per second taken for the length of the image set.
* Used maximum gain for all image sets. Exposure determined by manually slewing across the sun and trialling different exposures. Aim was to get as close to having maximum pixel values in the image, without actually having any maxed out pixels
* Where necessary, solar eclipse glasses were used to directly view sun e.g. to determine if clouds were obstructing the sun, or just the area around it
* Clear Filter 1:
* Gain 799, exposure 1/1000 seconds
* trees obstructing parts of image set - produces obvious errors in dataset
* Clear Filter 2:
* Gain 1023, exposure 1/4000 seconds
* Blue Filter 1
* Gain 1023, exposure 1/154 seconds
* Some obstruction of sun by clouds
* Blue Filter 2
* Gain 1023, exposure 1/154 seconds
* Still some clouds, but far fewer than with Blue Filter 1
* Green Filter 1
* Gain 1023, exposure 1/308 seconds
* Lots of clouds
* Green 2
* Gain 1023, exposure 1/308 seconds
* Even more clouds
* Red 1
* Gain 1023, exposure 1/1241 seconds
* A few false starts (so the file indexing is messed up), but managed to get a good run of images
* Was not able to perform another run with the green filter, due to increasing cloud cover
* Dome doors repositioned above door to roof and closed.
* Solar filter removed and lens cap replaced. Filter stored back in its home.
* Telescope returned to 0h0d
* NOTE: Minor mix-up with imgae file names. All image sets are stored in the appropriate folders / .zips for the colour filter used, but the some image sets use the wrong colour name in the individual image filenames. Recommend handling image sets carefully / renaming appropriately when used.

*
Start 17:48
* JD (Scribe),CH,RA,MH,SG,STB
*
1 Enter dome, close door
1 Release ropes and unscrew bolt (put it on the control panel)
1 Open dome - use the big stick (careful of stuff that can fall down when opening)
1 Tie up ropes
1 Take cover off telescope
1 Take off lens cover
1 Dial on bottom intervals of 5 minutes
1 Dial on side measured in degrees - declination
1 Turn on camera ST-8XME SBIG
1 Open terminal and find Betelgeuse and find its coordinates
1 Set telescope Declination and hour angle using paddle
1 Move dome to be able to see stars
1 To check if star is aligned look past telescope and see if there is too much black or blue, if aligned should see the star aligned along telescope
1 Using paddle change speed of telescope to speed 5
1 Then look into telescope and align a star in crosshair.
1 At top go to tools then ekos
1 Change telescope alignment speed 3
1 Open live capture set exposure to 0.1 and frames to 99
1 Using live capture align the star to centre on the video capture screen - should see red circle on star
1 To synchronise/zero coordinates use paddle go to top menu ->object -> star -> named -> star name -> enter -> hold enter for 2 seconds
1 On ekos go to camera tab and set exposure to 0.1s and preview, save image
1 Repeat for different exposures - longer exposure - bloom
1 Set to Orion Nebula coordinates
1 Pack up
1 Set telescope to 0 declination and hour angle
1 Set alignment speed to 9
1 Close dome doors whilst holding rope.
1 Close door and put screw back in and put rope back in metal thing.
1 Turn off camera
1 Put paddle back
1 Put lens cover back on and telescope cover back on
