Hi Martin, thanks for posting this. Startools was one of the first software packages I purchased starting out but I haven't used it for ages now, clearly it's progressed quite a bit & this particular module seems like a good reason to revisit.
I don't have PI so BlurXterminator is not an option. Keep up the good work with your imaging, for someone who once said "I'll always belong in the beginners forum" you've certainly proved yourself wrong

.
Cheers,
Tony
