NGC 7331

Adjacent to Stephan's Quintet is another galaxy group dominated by NGC 7331 (known as The Deer Lick Group). Another frustrating evening with dissipating contrails drifting across made getting useable subs for this subject a lengthy affair. It took over three hours to get 8x 10 minute exposures that weren't "pinked out" by cloud reflection. We have had an amazing run of clear evenings given how poor the rest of the year has been so I mustn't complain too much if some have been less than ideal. (The pre-dark photo shows my observatory roof in foreground). NGC 7331 details: 10" F 4.3 Newt. 8x 10 minute exposures @ iso800 with CLS in DSS , CS2 & XAT Image Optimiser.
