Very nice! Was there any sign of the nebulosity in the lum channel?

yes a little, but mostly like  gradient ☺️

Great image. More data will indeed improve the end result - but great image as is!

Hi
Thank you for your feedback.
I don't think there's more to come with more time, with my gear. But I can probably improve the result, with better editing skills

Perhaps one of the hardest ones I've edited, I think both HA data and OIII data were good, but it was very difficult to merge them into a comfortable rgb image. Maybe I get some SII data before the season is over from Norway. Appreciate feedback and feel free to give tips on composing HA and OIII
From my home observatory

Frames:
Baader L 2": 57x300" bin 1x1
Baader Ha 2" 3.5nm: 302x300" bin 1x1
Baader OIII 2" 8.5nm: 132x300" bin 2x2
Integration: 40.9 hours

Great picture

Yes, it is a very nice palette Ola! I am a great fan of your NB palettes.

This may provoke some: I like it when green is kept out of NB images - no real need for it to be there, unless you really want to be "scientific" and keep the signals from the three filters as much apart as possible. We do not need to imitate HST, in that contest we will always loose, but by chosing palettes like Ola we can win aesthetically. And one could argue we also wim scientifically since both Sii and Ha are red in the real world😉

Thank you Gørann.

I very much agree with what you say. I like this type of palette. But you've probably got that😉

Thank you😊

Sorry😕

Beautiful Ola!

I assume this is reprocessed data from your archive, or did you find a whole in the eternal cloud cover we have now?

Thanks

New post processing of old data

 Thank you. Very little signals, almost invisible in the rgb stack Olly

Brilliant, serious dedication there!  Chapeau to you sir.

Now for the colour version ?😂

Thanks.
The plan is to start with RGB in 2-3 weeks

Very good, what did you use to stitch it all together?

Thank you. 

I use Image Composite Editor

Very impressive mosaic Ola. I love big mosaics, and this is a triumph. 

One small piece of feedback if that's ok - i find the contrast a bit too much for my liking. The black point has been slightly clipped in a few places, and in others is also very low. But other than that it is a very impressive mosaic indeed! 

Hi, and thanks for the constructive feedback. I've also seen this. The problem has been that some panels only have 1 hours exp, and others 6 hours. I couldn't stretch the pictures equally, so the results were not good. I've stretched all the pictures completely, before stitching. So the exposure level becomes a little different throughout the whole picture
