Yes, Russ Crowmans BlurXterminator does seem to do a good job. I used it for the first time together with RC’s StarXterminator to process my C/2022E3 comet image here https://britastro.org/observations/observation.php?id=20230126_165855_917730cc9af3bb9a I’m also new to Pixinsight so the processing was very time-consuming and I guess could have been done better with more practice.
