I find I used to get bright coloured pixels in stars in CCD Stack if I stacked color subs rather than mono per channel. It gets worse when there's not enough pixels per stars. It's the bunyip's fault. Those stars are two damn round and sharp because the light is not spread in too many neibourghing pixels.
Might want to try that. I don't know your current flow but try stacking channels separately first then combine colour as the very last step.
