OBJECT

Andromeda Galaxy is the closest galaxy to us (except for the Milky Way satellites, the Magallanic clouds). It lies at 2.2 Million light years. It is a common target for amateur astrophotographers which always try to catch the spiral structure and details on the dark areas.

Cataloged as M31 on the Messier list, it goes with two other nice galaxies; the dwarf M32 and NGC205 (also known as M110) another satellite of the Andromeda galaxy.
