Thanks to all who have looked (and/or commented). The image is a crop of what I got from doing an "overlap" stack in DSS. It is difficult to frame each sub-exposure exactly the same (particularly when simply using a ballhead), but with DSS that doesn't matter because it will stack only the common parts of each image. From that result I cropped in even closer resulting in the "centered" composition that Stan didn't care for. I could have left more stars on the right and bottom, but I guess my thinking was more like what Paul expressed earlier. Also, the nature of astrophotography, particular with the lens near wide open, is that the edges will drop in quality due to coma, CA, etc. I didn't really have M31 centered well in any of the shots. It was mostly left-of-center or lower left. So again, lots of room for improvement with future images - even of the same subject. It is a learning experience and I have a LOT left to learn.
I don't see the banner either, but I'm also a paid account (if that makes a difference). Rather annoying to hear about, though. : \ By the way, I had a couple of astro imagers suggest a free PhotoShop plugin called HLVG (HastaLaVistaGreen) which I think I will find/download and try on this image. I thought I got the green out, but apparently not enough. To Larry's earlier question... not sure about stacking software for the Mac. I believe Steve Sharpe mentioned one up-thread. DeepSkyStacker and Registax are the two biggies (both free, I believe) on Windows. If anyone is interested, I can share a good link that helped me with the histogram/curve part of DSS.
