The Trifid region is another good example, decidedly drab, even kinda dirty in narrowband or any mix close to that, looks much better in LRGB.
There are many good examples of what I mean with the NGC 6559 region but just recently Steve Mohr posted an LRGB shot of the same field taken with the same scope and image scale as yours, so you can compare easily.
Hope that made sense

Thanks Mike. I did try the more trad Hubble palet but couldn’t get it to work well. Someone on another forum suggested adding a straight luminance. I will have a go at that when I get the data.

Hi Kevin. There is actually a scientific basis for this mix. See here
