- Description: Messier 101 - Spiral galaxy in Ursa Major. One of the larger galaxies in
the northern sky, M101 (NGC5457) is about the size of the moon. Covering 29 x 27 arc minutes, M101
glows at magnitude 8.3. As that light is spread over such a large area, M101 can be tricky to spot in
small scopes unless you are under fairly decent skies.
