Hello
sorry is been long time since when i have open the discussion but just today i’m been able to do a video about what i do and the result that i have:
indeed, you shouldn’t delete the star list before doing the resynthesis (what you are doing at 00:45).
If you have stars detected already, resynthesis will use them. If the list is cleared, I will do an automatic detection (so what you had before removing 2 sources manually).
I don’t see the problem. You deselected the two bright stars and those two stars were omitted from being resynthesized. This is exactly as expected.
If it’s easier to see how it works, try making a rectangular selection of say a quarter of the screen and detecting stars in that selection. Then hit resynthesize: the result will be that the detected stars (within the rectangle) are resynthesized and all the rest of the synthetic star mask will be black. Only the selected stars are resynthesized: if you detect all stars and then remove some, the ones that remain will be synthesized. If you only detect stars in a certain part of the image to start with, only those ones will be resynthesized. But if you resynthesize with no stars detected at all, then resynthesis will automatically detect all the stars it can and will resynthesize all of them.
