Hi Roger - one trick you can do in both PI or PS is to process the image in LAB space, and apply a tight linear clip to the histogram in the A and B spaces. This is pretty strong medicine but sure brings out any colour in the data. If you google it, there's a few tutorials on the web.
If you do your colour combine in PI, the final combination step when you drop the stretched luminance image on the stretched RGB also gives you a chance to really give the colours a kick, but counter intuitively you use a low value for the saturation slider and not a high one!
cheers,
Andrew.

I wonder if anyone has suggestions on how to bring out more colour variance on the galaxy?

Stacked in CCDStack then DBE in PI before post-processing in PS.
