Dietmar, that does not look like one of the bicolor compositing options.
Oops, you’re right, Mike! Thank you for paying attention.
Steve, Freddy, I’m sorry . I copied the wrong parameter value. It should indeed be [L + Synthetic L From R(2xG)B, R(GB)(GB) (Bi-Color from OSC/DSLR)] as written in Ivo’s post.
So, like this
2022-08-13 10_41_46-Window.jpg (25.71 KiB) Viewed 2279 times
This leads in the end more or less automatically to something like this

Best regards, Dietmar.
P.S.: As for your NB/RGB combination, Freddy, I think it's better if Mike answers.
Hmm, meanwhile i still going to try it. The red in the picture looks better, and the cyan can be adjusted afterwards in GIMP.
I don't like the magenta in my pictures but that is difficult to alter for some reason afterwards.
Freddy, yes, my hint was more for the HOO / bicolour processing Steve did in his case.

I admit, I sometimes do a little postprecessing with darktabe or GIMP, but most times only for brightness / gamma corrections. For colour processing, I think it should be possible to use just the Compose / Color module
As Mike wrote, you maybe should consider to link your stacks. People here are very contructive and could give great help.

Hi
With an 600d, by far the noisiest channel is the B. The main advantage of splitting the channels is that you don't have to use B at all. G carries the same colour data as the B, but is much cleaner. That's with our UHC filter. I believe the l-eNhance is similar.
Cheers

I understand, that's interesting. I will have to check my data sets for that. That must be a lot of noise, that it is better to to omit B and to loose a lot of signal / integration time, noisy or not.
Do you think, this noise in B is from your camera? Or due to light pollution?
Best regards, Dietmar.
Edit: I think, the G channel has usually better SNR with DSLR because there are twice as much pixels?! Just a thought ...
