Well, I think I figured out the secret to eliminate the onion skin testure on my 10 fps stacks. Photograph on the bright side. The histogram was taken between 225 and 250 on all of the colors in WxAstroCapture. Tonight's images were taken in 2 parts, the first set was taken around 2355Z, the 2nd set taken around 0310Z 12/4.
The detail is absolutely incredible. I'll let you see for yourself.
Now for the 2nd set. The 2nd set shows the GRS very well resolved, the gray ring around the GRS is plainly seen. The turbulence following the GRS is quite apparent.
I must say, I am quite pleased with the results. Shooting with the planet much brighter than I'm used to made a big difference in reducing the onion skin effects, and with more frames, I can extract more detail. Thanks for the tip, Joe!
