  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
