Not a lot of sophisticated processing has gone on here and I am lacking good data (especially OIII). However I felt I got a nice result. Very much open to suggestions of course. Planning on adding more data (time and flu permitting!) but maybe not RGB stars. I kind of like the way the purple stars have rather accidentally become an intense blue. https://www.astrobin.com/full/418906/F/
I find it odd that the diffraction spikes have gone AWOL
Oh, I didn’t do anything to them? Not sue how they got swallowed, maybe lost to some noise reduction and in my incessant fiddling? Do you miss them or is more that they are still kind of there but too blurry now? Could be also that the rather terrible OIII data has also had a role to play in messing up some of the Ha clarity. It’s pretty ugly and low res if you get close :-/
Realised something very fishy was up with the O3 data (wrong filter set perhaps) so got some more tonight and thus a slightly more complex rendition. As always thoughts/help welcome. https://www.astrobin.com/full/418906/I/
Lots of work gone into this and it’s looking really good.
Just a couple of hundred purple stars away from brilliant! 😀
Colour palette is well chosen too.

Cheers Andy. Might be a while for RGB stars but should be close to making some white(ish) ones :-)
The latest version looks great Ben, quite a grand feel I do like slightly magenta stars in NB images but if you could deal with the blue-purple ones it would look better
Perhaps no longer so grand but more variety of colour perhaps and whitish stars. Getting into a weird processing zone so thought I’d through this one out for any ideas? RGB stars would be nice but the moon has to move a bit. https://www.astrobin.com/full/418906/BA/?nc=user
Way too many versions of this now but ended up happy with this colour version before I (hopefully) collect and add the RGB stars. Curious about ideas for adding RGB stars. It’s seems some benefit might result from using the RGB star size for the brighter stars, and maybe using the Ha star profiles for the smaller ones? Do people do this or is the result rather naff? Better to be either/or? Any/all advice welcome. https://www.astrobin.com/full/418906/BR/
Thanks for the reply Andy. Although recent award winning images of yours don’t necessarily feature stars (!) I really do love the stars on your images. I don’t use PS (only PI) but perhaps I can figure out a mirroring process :-)
1) using PI only create a starless image with StarNet then use pixel maths to get an image of the stars, i.e. stars = original - starless
2) work on the starless image to bring out the background/nebulosity etc.
3) to add stars back into image use pixel maths i.e. new image = processed starless image + stars saved from 1)
Of course you can also reduce the star sizes before adding back to the processed starless image
As Andy commented it is a pain on a Mac but there is a process module for the windooze version of PI
