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. 21_34_49_lapl5_ap1564_Drizzle15_conv.jpg |

OK. So I cheated and converted it to grayscale instead. Hey beauty is in the eye of the beholder  .... Hoping that one day I will get to know why this did this, and that the moon forgives me for now. |

I don't know if I would consider it cheating. It's a great image. I've had a similar problem stacking planetary and lunar images. I did an extensive search on the Internet, and found this: https://skyinspector.co.uk/mars-edge-artefact/ It's quite lengthy and I couldn't understand some of it. In the end I tried being less aggressive with sharpening and that seemed to help. A. |

Thanks for the comment and reply. The moon is quite forgiving for newbies and I am certain it is a procedure thing. It was how I have always imagined taking images of the moon would be only it was never explained how intricate every step of the process is. AS!3.x is terrific. Pro's make it look and sound so easy (hat's off to them) so I hope I have clear skies for the next full moon to refine my approach. I am yet to fully appreciate how much time and skill is required to get those truly awesome images. Having access to great software is a game changer and we are literally able to stand on the shoulders of giants. So many inspirational photos here. I'll make sure I don't tackle that link on an empty stomach. I aged a bit just scrolling down to the bottom  )
