Looking for some help and guidance, please.

 

I have a Coronado SolarMax III 7Omm double stacked. I want to use my Baader Mark V binoviewer with it. How do I connect the 2-inch binos onto the 1.25 inch blocking filter on the scope? Or can I?

 

Thanks!

I know that Lunt has a T2 male thread on the top of the blocking filter but I am not so sure that Coronado does this, but if they do, then you would just mount the Quick Connect ring right on top of the blocking filter. 

 

Otherwise, you would need to use a 1.25" nose like this:

I assume you already have a quick connector but if not, then you would need that too and the 1.25" nose would go on to the quick connector. 

 

My guess is that you would need to use the 2.6x GPC or the Televue 2.5X 1.25" Powermate. If you can find a Bino Vue 2x amplifiier that might work as well.

 

Also, some bioviewer Barlows might work as well but this depends a great deal on how much focuser travel you havel.

Even then should measure your avialable focuser travel. Even with the 2.6x GPC you will still need to have about 30mm of focuser travel from where the focuser is when using a standard eyepiece.  

 

Best to start with measuring the focuser travel remaining when you use a standard eyepiece.

The Coronado also has a T2 male thread on the blocking filter. It is 1.25 inch. The binos are 2 inch. What Quick Connect do I need to mate the scope and binos?

 

BTW, a XW14 eyepiece takes every mm of focus. Tried that eyepiece for fun and the view was super!
