I have been using AstroBlinkV2 (GitHub, GPL) for lights triage. Currently it is capable of writing out a csv of quality scores or injecting the score into the FITS/XISF header as a keyword using the SSWEIGHT/PSFSWGHT formula.
When I stack I use a combination of filters and usually Siril’s FWMH weighting. I would love to see a feature where I could use a fits embedded keyword. What do you all think? Is anyone else using externally computed quality metrics?
I can move this to the gitlab issues as a request if that is more appropriate.
