Finally figured out the stars — the whole problem was in the crooked stacking in DSS. In PixInsight I couldn't stack, so I had to learn Siril. For a long time I…
I tried processing it in the HOO palette, but nothing decent came out with the stars (though on individual frames the stars look fine). Maybe over time I'll fig…
Yes, StarNet in PixInsight plugin.
Can it be split and combined only in PixInsight or Siril? And what would that give. StarNet kind of grabs the background in tatters.
If you split it in Siril and align the stars a bit better, it will gather them into clusters and remove the shift — there's a button for that in the alignment stacking section. Then, if you crop them a bit tighter, the background will be denser. If not, you can stretch between the stars using GHS and dim the stars either with StarNet or some other plugin.
Do you cut out the stars before stretching and then stretch them separately? In PixelMath, combine them: + . Substitute your own image names. Stretch the stars only slightly. Try a few stretches to find the right brightness so artifacts don't appear. And tell me how you stretch the stars.
Yes, I remove the stars before stretching the histogram. After color calibration, I stretch them by eye and run them through morphology and deconvolution in PixInsight. In this case, those scripts were cranked to the maximum. Then I combine the image and the stars using screen blending in Photoshop.
So the issue is most likely with the deconvolution. First, make sure the stretching is fine by reverting those changes. And if everything looks good, then you can play around with deconvolution. I also got some weird results with it in Siril and gave up on it, I just stretched the stars less instead.
Regarding the defocus, I'm not sure. I deleted a few frames that were overexposed, possibly due to clouds. There's a chance that a few low-quality frames made it into the stack. I'll gather a couple more hours of signal and shoot the stars through an IR cut filter, then re-stack. Thanks for the link, I'll check out what that program is.
