Frame 1 of a whole Cassiopeia mosaic by cybermystic, on Flickr

Lovely clear sky last night but an annoying intrusive Moon. Started off Moonless and I thought I might get the whole of Cassiopeia done. Unfortunately during the first (of four) frames - up came the Moon, so I stopped after the first frame. Only 17 subs at 4-minutes per sub. Epsilon towards top left, Ruchbah towards middle bottom, Gamma Cass over far right towards bottom. So what don't I believe? You can actually see a touch of the Gamma Cass nebulosity there :shock: :shock: :shock: Incredible. Un-modified Canon 5D MkII. If I had gone for the usual 8 hours for a "good" image - I think this might turn out looking pretty decent. Still - I do have Hyperstar III Gamma Cass data for a composite - but it still makes you think :D :D
