Playing around testing configurations the other night from home. Test target was Omega Centauri globular cluster. I was spoiled recently by imaging at a dark site. Home here is pretty heavy light pollution. Caused me some grief with white balance. Tried for hours mucking around with different methods trying to get the pink/orange vomit colour out of it. Ended up getting most out ok, but the stars still looked a little pink to me, so desaturated it
