Hey Paul,
I see a strange color gradient in the stars - but not the bgd - from bottom left (Blue) to top right (Red). Or put another way, there are very few red stars in the BL corner, and no blue stars in the TR corner. TL and BR corners have a normal spread in star colours. Is this what you meant by funny gradients? I must say I've never seen this effect before, usually the bgd tint varies along with the star colours, I suppose you were able to process the bgd shift out, but the color balance was still shifted.
Details are quite good in the galactic cores, no need to fool anymore with that.
Best,
EB
