M108 is a galaxy about 45 million light years away in the constellation of Ursa Major. It is sometimes called the surfboard galaxy because of its resemblance to a surfboard. Note the huge number of tiny, distant galaxies in the background. These are hundreds and in some cases up to two billion light years away from us.
Technical Information
I imaged M108 from my backyard observatory in Nottingham, UK on 4-5 April 2021 (two imaging sessions) when M108 was almost directly overhead. Conditions were very cold and frosty with good seeing and transparency. I used my TEC140 refractor and Atik 460 CCD camera with Astrodon E series Gen LRGB filters (1.25″). There is almost 9.5 hours of data in this image consisting of:
Lum > 42 x 300s; Red > 24 x 300s; Green > 24x300s; Blue 24 x 300s
Everything was binned 1×1.
Image data was captured using Sequence Generator Pro software and the equipment was was guided using OAG on my MESU 200 mount. Processed with PixInsight.
I hope you like it!
