Galaxies

Galaxies tend to come in groups, and, after the local group this is the next nearest with M81 being the primary galaxy at a distance of 12 million light years. Also in this picture are other members of the group; M82 and NGC 3077. With a more aggressive screen stretch it’s also possible to detect the background galaxy UGC 5336 just to the left of M81.

As Wednesday evening was clear and still, I took the opportunity to gather 2 and a half hours worth of 3 minute exposures at ISO 800 with my ZenithStar 70 and Williams Optics field flattener. Bias and flat frames were also used in the image processing but not dark frames.
