Well, I'll be stuffed. So it is. Andrew, thanks for that link. I'm convinced. And Marc also, you're both right. And the solution is - stay away from over-bright stars or do really short exposures. Hmmm. Not much of an option. So it'll have to be a post-processing thing. New skills coming up.
Now I know this I don't have to bother horsing about with the IR filter - but Marc, why did you remove yours and if you use it on a hyperstar, how do you maintain the separation distance?
