Thanks Mark, Alex and Marc
Yep - more processing to do Marc. I managed a few minutes-worth before climbing into bed last night. Will see what happens with it today. It was disappearing into the western horizon when I finished with it.

I was just getting to the 1200 sec exposures when both the sky and my eyelids went. LOL!
I've left the mount set up outside overnight, so I hope that it's OK for tonight to get more time on it - doesn't look promising though.
