Gamma>=120 causes Onion Skins for me
I just did some extensive testing with IC Capture and a DFK21au04 (color) and for me on Jupiter, brightness wasn't the issue - the deciding factor was having Gamma at or above 120 resulted in onion skinning. Below is my last round of data. G=Gain (0-1024), Exp=frame exposure (seconds), Gamma (0-255), Brightness (0-63). For reference, on my system C8sct with 2.5x barlow, Exp of 1/30s and Gain of around 500 makes jupiter almost completely invisible (dark) so my tests of G=650 mad for a pretty underexposed image.
Hope this helps!!
