The stars are not too bad in the center but the suffer out near the edges. That's because the C8 does not have a perfectly flat field. Its curved a bit and it causes oddball star shapes in the corners. To fix the stars at the edge, a field corrector lens is required.
The star colors are pretty much non-existant too. Not really sure why that happened but it did. Probably too little exposure time and too much stretching.
But otherwise, it's actually not a bad photo considering the gear used and my complete lack of experience at that point. One thing I learned from this and other similar photos is that star clusters can be successfully photographed from city under a bad light pollution dome.
Most, if not all of the stars in this picture that are competely invisible to the naked eye from my back yard. Even binoculars only show a few of them. A big telescope will show lots more but only on the best nights under no moon. But the camera picks them up no problem at all. And with the right technique and good gear, it does a pretty good job of it too.
