Marmot Posted June 15, 2021 Share Posted June 15, 2021 Two good images. On this occasion I can’t decide between them as they are both great! 1 Quote Link to comment Share on other sites More sharing options...

I think if I were better at processing and knew how to prevent the cores of both nebula from blowing out with the additional Ha data then it would be better. I feel as processed, I like the original non-Ha version better. Quote Link to comment Share on other sites More sharing options...
Padraic M Posted June 15, 2021 Share Posted June 15, 2021 How are you mixing the Ha in? Are you including it in the Red channel, or adding it as Lum? You seem to be losing some colour and detail with it. Quote Link to comment Share on other sites More sharing options...

Greg M Posted June 16, 2021 Author Share Posted June 16, 2021 Here's a re-process of the data, I deleted the Lum channel and just stacked RGBHa with Ha added as Lum. 4 Quote Link to comment Share on other sites More sharing options...
Greg M Posted June 16, 2021 Author Share Posted June 16, 2021 Just for grins, a Starless version. Quote Link to comment Share on other sites More sharing options...
Padraic M Posted June 16, 2021 Share Posted June 16, 2021 That is definitely much better! The star-ful version looks fine but you could try blend the stars back in from starnet++ at 50%... Starless images always remind me of Caravaggio! 1 Quote Link to comment Share on other sites More sharing options...
MarkAR Posted June 18, 2021 Share Posted June 18, 2021 Three excellent iterations (not counting the starless). I think the HaRGB being the best. Wonder what an HaLRGB would look like. 1 Quote Link to comment Share on other sites More sharing options...

Didn't read it properly, yes it looks like the Lum blew out the core. There are ways around that but I'm not familiar with APP. Quote Link to comment Share on other sites More sharing options...
Gina Posted June 19, 2021 Share Posted June 19, 2021 Wonderful. Yes, a version with stars re-added in a lighter tone would make it perfect. I hadn't thought of RGB for those nebulae - I mainly stick to NB - but that has come out superbly, particularly the HaRGB. Quote Link to comment Share on other sites More sharing options...
