I have only had one BV (Celestron) an found it very disappointing. So I am thinking of trying the MB II to go with my C-8/E and Esprit 120. I already have 2, T-2 prism diagonals. As I have some Naglers (7,9,16, 22) I was wondering if one of use had any experience with this combination.
I was thinking of getting another 16mm to use/start with.
First of all, if the first experience was disappointing, it might be better to kind of explain what was disappointing about it.
But that is neither here nor there to your question.
Nalgers can work well, but if it is an eyepiece that requires you to tilt your head to take in the whole field, it will probably not prove satisfactory for binoviewing. When you turn your head to one side of the other to see the edge of the field in an eyepiece you IPD changes and this will usually cause you to loose the exit pupil in the other eyepiece.
If on the other hand you can take in the entire field without having to move your head from side to side, this it should work Ok. Since this is a function of both the observer and the each specific eyepiece it would be hard to tell you that it is going to work great.
