Here's one i've done tonight (jpeg files only) - it's about 4 hours long with a setting of 1600 ISO, f2.8 and 30 secs. It does indeed bring out more stars!!
It was a little over exposed however - I should have checked the view screen before hand and reduce the exposure to 20secs or so. The final image was adjusted (levels) to darken the detail a bit..
All up approx 470 images (16gb memory card ended up being full)
I will play around with the raw file soon and see if i can achieve better results from that.
