A better evening allowed me to get a dozen subs for this image with much less trouble than the last post. Known as "The Bubble Nebula" NGC 7635 lies in Cassiopeia not far from the dense cluster M 52. I was pleased to capture the full circumference of the "bubble". Details: 10" F4.3 Newt. 12x 10 minute exposures @ iso800 with CLS in DSS & CS2.
