Description

I have had a lot of sunny dry weather here, months of virtually zero rain in fact, [very unlike England], but that does not necessarily mean clear nights. In-between varying degrees of night cloud, I thought I would use my nemesis, the big scope!, which I struggle to get good guiding with. I have made some improvements though, although the stars are not quite right yet. Here is a Cocoon nebula image, taken in between high clouds and dodgy subs, totalling 3 hours and 24 minutes imaging time - 68 subs at 3 minutes each. I ran it at f8 rather than the native f12. It is far from perfect and coma issues and more imaging time would have been desirable, but I am pleased with the progress. Thanks everyone...
