DaveS Posted October 3, 2020 Share Posted October 3, 2020 This is 9 hours each [NII], [OIII] and H-alpha in 10 min subs as NHO. Capture with TS 130mm apo, ASI 1600 and Astrodon filters. Initial stacking, RGB combination and stretch in AstroArt 7 using a mask to hold back the core. Mask also used for the denoise and unsharp mask.Channel mixer, selective colour and clarity in Affinity Photo. Crop and resize for export.This was the main capture while I was getting data on Melotte 15. 4 Quote Link to comment Share on other sites More sharing options...
DaveS Posted October 3, 2020 Author Share Posted October 3, 2020 Damn. I think I drew the mask a bit too small and left a bright ring around the edge of the core.Oh well, I'll have another look at it, probably tomorrow. Quote Link to comment Share on other sites More sharing options...

MarkAR Posted October 3, 2020 Share Posted October 3, 2020 It's still a superb image, are you still playing with it? Meant to have a go at your data, have you got xisf files I could have a bash at ? 1 Quote Link to comment Share on other sites More sharing options...
DaveS Posted October 3, 2020 Author Share Posted October 3, 2020 Hi no, I don't have PI, looks too scary for me. This is mostly in AstroArt which I've become used to over the years. Quote Link to comment Share on other sites More sharing options...

DaveS Posted October 4, 2020 Author Share Posted October 4, 2020 Thanks guys.Still bashing this one, trying various mask sizes to hold back the core without creating a bright or dark ring. Quote Link to comment Share on other sites More sharing options...
Gina Posted October 4, 2020 Share Posted October 4, 2020 Very nice Dave ? Looking forward to seeing the final image. 1 Quote Link to comment Share on other sites More sharing options...
DaveS Posted October 4, 2020 Author Share Posted October 4, 2020 One more iteration. Lots of masks used, DDP histo stretch selective colour and chaannel mixer in Affinity, noise reduction and unsharp mask in AA7 with a mask to protect the core.My Dumbbell folder is getting chock full of images in varying states of completion. there may be 27 hours here, but I have my doubts about the quality of those hours, as the sky was often lacking in transparency, and M27 was getting very low towards the end of several imaging runs.Never mind, mind more work to do. 2 Quote Link to comment Share on other sites More sharing options...
MarkAR Posted October 4, 2020 Share Posted October 4, 2020 Dave, step back and call it done. Thats a cracking image. 1 Quote Link to comment Share on other sites More sharing options...
don4l Posted October 4, 2020 Share Posted October 4, 2020 That is fantastic. There is detail there that I've never seen before. I must admit that when I saw "M27 27 hours" I wondered if it would be worth it. The result is definitely worth it. 1 Quote Link to comment Share on other sites More sharing options...

Carastro Posted October 6, 2020 Share Posted October 6, 2020 The 2nd version looks really good. Any chance of increasing the colour in the stars?Carole Quote Link to comment Share on other sites More sharing options...
