Description

After many weeks of cloud and rain, I was blessed last night with a clear patch that lasted the whole evening and with no high thin cloud giving me satisafctory transparency, hurray :-). So I grabbed what data I could as the coming week's forecast is reverting to autumnal grey. I have a variety of orientations for this target in my PI workspaces: I am trying to avoid any dubious similarity to a manifest 'Portnoy's Complaint'!

The night's imaging was also the first full evening's use and scripted automation for my new Lunatico Astronomia Dragonfly - super bit of hardware that scripted my equipment power off and PC sleep after the sequence all finished. Thank you Jaime.

Thanks for looking!
