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.
