Hi Barry ,
It's a one shot colour , I tried 10 minutes at full resolution and stretching brought the inevitable noise of two few photons. That's why I tried 5 minutes at 2x2 binning to get more signal at the expense of resolution. Perhaps I should have tried 10 minutes at 2x2 with more subs at the expense of less sleep!
