M31 - Andromeda Galaxy

This is a four frame mosaic.  Even with four frames this galaxy is so large it still extends beyond the field of view.
You can see the satellite galaxy M32 at the top of the frame.  Another satellite galaxy M110 is just off the field of view at the bottom edge.

Note: This image received 2nd Place for the category "Deep Space - Galaxy" at the 2004 MidAtlantic Star Party Astrophotography contest.
