Galaxy in Andromeda.
The last object in Messier's list, Messier 110 is one of two bright satellite galaxies of the Andromeda Galaxy (Messier 31). The Andromeda Galaxy itself can be seen with the naked eye. With a good pair of binoculars or a small telescope, its two elliptical companions can also be seen. Messier 110 is larger than the other companion (Messier 32), but it is also more diffuse and more difficult to see.
In this image, a faint band of light can be seen extended downward and to the left from the galaxy. This is not a photographic defect; it is a stellar bridge that extends from Messier 110 to the much larger Messier 31, which is just below the bottom edge of this picture.
