Has anyone used Binoviewers on a reflector? Ive got the 200p explorer and fancy a pair but I'm worried about the focusing/using a Barlow...

I'm sure I read somewhere they don't come to focus on a reflector, I could be wrong though but I'm sure I've read it.

My gut feeling would be that they won't reach focus unless you are able to move the primary or reduce the height of the focuser.

Because "most" newts are designed to take the eyepiece in the focusr with no diagonal, (you dont need one on a newt) they have little focus travel unlike most refractors designed to have back focus, therefore you wont reach focus with a bv unfortunately. Unless you moved the secondary and focuser closer to the primary that is or as mick says move the primary, then youd probably need a bigger secondary to make up for the loss in the light cone
