Hi all,
Had a session where for some reason my stars all have a little tail sticking out to the left. Must be a bad frame that I cannot find.
It has not been a problem on subsequent images but I would like to salvage my image if possible.
I thought I would be able to deconvolute the stars to fix but having no such luck. I am using Siril and GraXpert.
1) Siril Gausian works great, but the stars look like they were pasted on the image, so no go.
2) Siril Moffat looks much more natural than Gausian but adds little pixels around the largest stars (looks like a solar system orbiting a star).
3) Graxpert deconvolution does something to the background of my star mask that makes it impossible to incorporate it back into the main image since it brings the amplification of background artifact into the image once I've stretched it in Siril.
4) Cosmic clarity adds lots of artifacts, so not helpful either.
5) I don't have PI (but maybe that is what I need?).
So, I guess the question is "how do I fix my stars with Siril or Graxpert in a way that will not mess up the rest of the image?"
Maybe I just have the wrong settings for the programs I am using?
Thanks for the help!
Paul
