Thanks all. I appreciate your comments.
Fred and Adam: Although the camera has 3056 x 3056 pixels, 80% of them went in the crop! At 2.4m focal length, I can't really get up close to a galaxy of this size. Hence the thumbnail, which is heavily compressed by the iis upload, isn't all that bad. Certainly some of the whispy outer parts of the galaxy don't show as well, and the detail is not quite as crisp, but the only way, I think, to get you significantly tighter details would be 20 hours of exposure....or, of course, a bigger OTA.
Thanks again for looking,
Mark
