Newbie question on autostakkert 3.1. I tested some SER movies captured in SharpCap v4 pro last night; processed in AS!3.1 because it was fast and simple to do.
Tested: a) Redcat 71 with ASI178MC on top (350 F/L); b) 127ED APO 0.7x red to ASI 533MC Pro under (952 F/L) - finer resolution in b)
Each captured was raw16 colour 100 frames to SER; 2 different telescopes, 2 different cameras (piggybacked looking at the same moon). Tested results in both debayered (using SER player to debayer using RGGB) and raw SER. AS!3.1 was tested both unsharpened and sharpened, drizzled and undrizzled. Typically picked 40-50% of best images each process.
The output from the ASI533MC raw (debayered in AS!3.1), sharpened, RBG aligned, and drizzled was outstanding. Simple and fast result, was really impressive. Using the same techniques with the AS178MC I get green bleed in the final output. Shown below. I have to undrizzle/unsharpen to get a slightly blurred (but still very acceptable) output from the ASI178MC without the green bleed. Tried filtering better quality/fewer images, changing AP grid size and tracking/alignment positions but nothing removed the green bleed. I could reduce it, but not remove it. It is almost a fantastic picture ...
Q1. What have I done wrong somewhere in the capture/processing?
Q2. Is this an artefact from the camera or the telescope? or am I just doing something wrong?
Q3. Is this a debayering thing? What is the optimum processing workflow for lunar pics using AS!3.x or other?
Thx, appreciate any help.

.... Hoping that one day I will get to know why this did this, and that the moon forgives me for now.
