Messier 81 and 82


Two of the most interesting galaxies are found in Ursa Major, better known as the constellation containing the Big Dipper. This image of these two bright galaxies was made with an 8" f/3.68 Faworski Astrograph mounted on a Paramount 1100S with a ST10XE w/CFW8. The moon was still up when my friend Sheldon and I started this image. As normal, this is the sum of a number of sub exposures that are put together in post processing. The final processing was done by our friend Sean Walker who is one of the best. There are a number of smaller, fainter galaxies visible in the image if you look closely.
