This rich field of galaxies is dominated by the bright SA(s)b spiral NGC7331, a 9.4 magnitude object with an inclination of 6 degrees from edge on. Six other field galaxies appear in this images as well as a host of very faint anonymous objects. Below are full sized pieces of the original image with the individual objects shown, the faintest of which are 17th magnitude. You can use the chart I generated below from Megastar 5 to locate them:
