Tonight I thought I'd shoot an H-alpha target since I already had the scope setup for it. The camera was on the scope, focused, Ha filter installed and ready to go. So I shot the Bubble Nebula (NGC 7635) in Cassiopeia.
This shot is 2 hours of 10 minute subs and 12nm Ha filter. The shot is the red channel only processed as a grayscale image and then colorized to a red again (Noel Carboni's B&W To Ha False Color Black Space).
