Thats fantastic Dennis, congratulations! Excellent image, and indeed a busy patch
I like the detail with the mag19.21 star by the way What's your limiting magnitude with the C9.25 and SBIG cam Dennis? I have reached 19.25-19.50 with the webcam, but that's with a 10 inch. Then again the webcam's QE is supposedly a great deal lower than the SBIG's.
Since I don't use guiding I'm currently limited to 30s exposures due to my G11 mount seriously being in need of some new grease for improved tracking performance... (it used to give me pinpoint stars at up to 4 minutes). With the current 30s I only reach around mag 18.50, but I'll fix the G11 soon and take a 'deep field' with a stack of 3-4min exposures just for the fun of it. It would be great to get beyond mag 20
