Nice go there Andrew, nice sharp sections in there. Some halos around the stars probably from the ha channel mixing. Maybe try using a starless Ha version. Or use Lightroom CA removal tool, thats very effective

Yes i too love the obvious targets, always something different to be seen.

Thanks for some good suggestions, I think the blue halos might be in the data as the conditions were extremely variable across the three nights but I'll take a look. The Ha only got used as part of a stack into the luminance channel, and I haven't done much with that yet.
I think you get out of this forum what you put in, and I rarely have much intelligent to say about other's photos, and certainly get more good advice than I give. So I'm grateful when people take the time to help me improve.

If you get the Dark setting too long you get black rings, too high and you get that swirly stuff. Colour looks good albeit a bit saturated for my liking, others may disagree there so personal preference

Hi Colin - thanks for picking that up, I saw that when I was parameterising the decon in the central region and have actually mucked up the luminance mask since there should have been no decon going on up there at all. Agree on the saturation, but I usually get more oohs when I tart it up a bit :-)
