Well, well Mike. “Keen” is an understatement for your efforts. …and talk about efforts, you’ve obtained marvellously rich data on the Helix neb considering the "environmental conditions"* you describe. I really enjoy the structure presented in NGC3576 as well. Unfortunately you couldn’t escape the effects of the high-level cloud with small halos present around the brighter stars. None the less, they do not detract from this great double acquisition. Very crisp.
Watch out for ghosting; -35 degrees cooling is getting down there. So you didn’t achieve your primary goal of testing your new LRGB filter set… I look forward to seeing Ha(L)RGB versions of these images.
* I agree with Fred, you’re going to have to stop bantering on about the clouds, weather and crap like that. You sound like a dinner party chef apologising for the cold food, full moon, political actions, flu and other illness, blah, blah etc. Just eat it and enjoy mate.
Magnificent work
