NGC7635 Bubble Nebula

Since I haven't been able to get out and do any astrophotography lately, I've been going through old data and practising processing. A very generous member, Sean "Falcon-" Murphy on the Cloudy Nights forum, offered some of his raw data to use.

One of the objects he offered was the Bubble Nebula. I've been fascinated with this nebula, lovely delicate shape of a very obvious bubble (top right). It is also not visible from where I live, so will never get an opportunity to image it. He also included in the shot the open star cluster M52 (bottom left).
