NGC7331 - In Pegasus

Not the best image I've ever taken, it was an attempt to try and capture Stephan's Quintet in the constellation of Pegasus. I didn't have a detailed enough star map to nail down the galaxy group with any precision, as there are no bright stars in the vicinity, so I had to centre the image on NGC7331 which is nearby and visible at the eyepiece. I have no Go-To trickery on the mount to help me in these situations but I enjoy the challenge of star-hopping anyway. If you look closely and use a bit of imagination you can see a few fuzzy patches where the quintet should be, about a third of the way along the top of the image from the right. There are also a few galaxies just below NGC7331 but I haven't identified them yet. This seems an interesting part of the sky but not one I'll rush back to as I don't have the equipment to do it justice yet! Processing has also exposed some large ring shaped gradient variations in the background, something I'll have to investigate further....
Taken with my usual equipment on 18th August 2010. Only 8 images stacked.

The rings maybe due to imperfect flats.
The galaxies below 7331 are, together with 7331 the Deer Lick group. And yes, those smudges at the top right are Stephen's Quintet.
That coma corrector is working well.

I think you're right about the flats, the paper screen on my light box looks like it's absorbed some moisture and is no longer stretched tight, I'll have to replace it with some cloudy perspex....
