North America Nebula (NGC 7000)

Taken the same night as M31. I took four images, but somehow they were rotated slightly in relation to each other and I could only get two to align decently. Some sing the virtues of photography because it brings out details you can't observe visually. In this case, Bill, Bill & Bob (also at SOS that night) and I were unable to see this at all visually, yet there it is in the photograph.
