NGC2237 from my backyard in heavy light pollution. It's badly centered because making this picture was a "leap of faith". I almost didn't see the damn thing during my test pictures and I didn't want to make too many tests because of the cold. I ended up doing 60 pictures. 54 were kept by DSS. That's all that my battery gave me... Also, it was right over Montreal (south) when I took the shots. There is no LP filter that can undo that...
