That sounds like a great example Houghy! Me smart ? I thought it was your idea!

the interesting part to me is the fact there are so many stars -and as you say resolved to pinpoint areas of light rather than a glow.

Yes indeed. When I was planning the image, I actually took a couple of areas as 6 hour images, when trying to determine the necessary exposure times. Believe it or not, there was little added benefit in going from 2 hours to 6 hours. The SNR was higher, but there was very little extra detail visible. That's why I settled on 2 hours for each image.

I sold the G11 about 3 years ago and had a Paramount for a couple of years. I sold the Paramount about a year ago and bought an EQ6 Pro.
I catch up with my old G11 at astrofest and you may have seen it too, in the hands of Greg Bock for the last two astrofests!
