M81 and M82 in Ursa Major

Our Local Group of galaxies consists of two major members, the Milky Way and Andromeda, plus a couple dozen smaller ones. The nearest somewhat similar group lies 12 million light years away in the constellation Ursa Major. Its major members are seen here, with the large spiral M81 at the right. M82 is seen edge on, which makes its actual layout unclear. These bright galaxies are a prominent target for amateur astronomers.

This was made with my 92mm refractor from about 30 5-minute exposures using a ZWO ASI294MC Pro camera. My site was in the Mojave Desert with a Bortle Scale number of about 3.
