Coma Corrector threaded wrong with T2 adapter... How to remove it?

[AlanP_]

Hi all,

My coma corrector is threaded wrong with my t2 adapter for my canon camera. When I try to take it off, it just keeps turning and turning but nothings happening. It’s squeaking when I turn it too so it’s obviously threaded on wrong. How the hell do I get this off? I don’t want to damage it.

Ok, got it off but I think the threads are ruined

You might be able to restore it with one of these or something similar
