The Andromeda Galaxy

With good eyes at a dark location, you might see a faint smudge of light located about halfway between the Milky Way and the Great Square of Pegasus. This is our nearest galactic neighbor, the Andromeda Galaxy, also known as Messier 31. It spans an area in the sky several times the angular size of the Full Moon, but most people don't notice it. Regardless of this lack of notoriety among the general public, the Andromeda Galaxy is at least twice the size of our own galaxy, and appears to be heading straight toward us!

This is a difficult object to image due to its size. A patient person with enough time on his or her hands would do it in sections and build a mosaic. Not being particularly patient or possessing much time, I chose to do it in one series of shots. It barely fits within the field of view of my camera on the ST80; and since I do not have a field flattener there is a noticeable distortion on the edges. Still, I think this is my best one so far.
