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.
