IC 2177 The Seagull Nebula is a beautiful region of nebulosity in Monoceros. 3800 light years away. I don't have a very big window of opportunity to image this target, because of trees and rooftops. I thought it came out pretty well for such a short Integration time. I am really liking the L-xtreme filter!
