Coma correctors for fast newts
There's the MPCC of course - something of a standard - but when backfocus problems make the MPCC unworkable, you go looking for alternatives. I need to find a corrector that will give me another 5 or 6mm to play with. What do others use on their fast newtonians (if anything)?
