Struggled with seeing and focus with the 14.25" f/3.56. This was the best I could manage.

What did you do at the terminator?  Is that WinJuPOS measurement issue?
 

[Mike Spooner]

No WinJUPOs. Not sure what caused it except perhaps a longer exposure and lower gain (16ms and gain of 200). Here are the 24% (of 10k frames) stacks unsharpened and sharpened out of AS!3. They even show a bit of the hard edge and maybe sharpening and deconvolution brought it out. I normally image Mars with 2 to 4 ms exposures to get the frame rate up.

Also including the R6 output.

Might be posterization from the camera. Don't know what camera you use but my ASI678MC shows similar effects at lower gain. Shooting at a higher bit depth fixes it for me.
