For what it's worth - a screenshot of a colour saturation method that works well in PI, without resorting to curves... FYI the image is ~60 minutes of 3 minute exposures.
I found this in a very old PI tutorial back when I started with v1.5 - it's hidden away somewhere in the archives.
It's a simple addition of the L or L* channel - extracted gray mask, applied with the mask active.
As an RGB image has an average luminance value of L, it's just a case of adding another L to get LRGB(L). If you are doing M45 it's ideal for boosting colour and retaining detail.
If you play around with the Gray image contrast you get different saturation effects.
Apply near the end of processing, following the first histogram stretch after SCNR green reduction and any Multiscale operations you might apply.
EDIT: usual caveats - don't overdo it and select the square button - not the round one to activate.
