I've only been doing EAA for about a month now. I'm mostly going after the big WOW objects that I've seen many, many times before in my Dobsonian. My favorite galaxy has always been M33 and I got my first image of it with my AT72EDII.
It would take me a little time to track them all down, but there are at least 10 NGC objects in that image - the brightest being NGC 604 near the top.I'm completely blown away by how much I can see with a 2.8" telescope from my front yard. I haven't gotten down to 17m yet, but 15m seems fairly easy within small galaxy groups...
An addition to finding other DSO's in the M33 image -- look in the galaxy itself.
Look for globular clusters in M33 -- you should find a Sky and Telescope and Astronomy reference. There are 4 that should be relatively easy to find in your image!
