I'm such a dumbass!!!
I've been using my Baader MPCC on my QHY8 when attached to my
ED80 for recent cometary work.
Is it even needed??? It was left on as I swapped from 12" Newt, to SLR lenses and now to the ED80 and I never even realised I was using it.
As it is a coma corrector primarily for reflective Newts....what would be
the downside (if any) of using it on refractors or SLR multi element lenses?
thanks in advance.
I shudder in horror at the hours of data I have collected with it still in place......
