I tried out this feature and have some comments. I run StarXterminator to separate the stars and this starslayer I open in Siril and convert to fits. Then open PSF window and let Siril detect the stars, around 50000. Then go to Star processing → Full Resynthesis. Then I get a result. First thing I noticed the image becomes dark and needs stretching (I already done some stretching for the stars before StarXterminator). Not a big problem, a few curves stretching and the stars are visible again.
Second thing i noticed is on some brighter stars there are some colored pixels in the center, https://i.postimg.cc/d160Gwj5/colored-pixels-1.jpg

Most of them I can remove but would be better if this was fixed.
Third thing, some brighter stars or some stars that are close together it removes them completely.

Not a huge problem but for the authenticity of the picture would be better to have the original stars.
The elongated stars are completely gone and the stars look nice and round, so there are good things going on.

Hello. To get more star you need to update the dynamic psf parameters.
The full resynthesis fuction works really good.
But there is one problem: bright stars vanish after full star resythesis.
And also stars which are not detected or manually excluded vanish.
My expectation is that these stars remain unchanged.
My time consuming workarround in GIMP:
I creat two layers and add the vanished stars into the resythesized star mask with the brush.
Would be great if there will be an option (or by default) to keep excluded stars as they are.
