Newbie Question

Hi all,

I'm new to binoviewers and was wondering if someone could steer me in the right direction..

1. Do all binoviewers work with all telescopes??

2. if not how do you know which binoviewers work with which scope??

IE: I may be looking for one that would work with my 12" f5 dob and a ( if it ever gets here) Burgess 102f6 refractor.

Any good sites to start with??

Thanks
