Would the Alan Gee Mark II (UAG II) work with a Binotron and a Edge 8 ?

If so what would be the best configuration and optical path to make it work ?

 

thank you

I have not used this configuration but my experience suggests that you would get some meaningful aperture loss (maybe reduce to 6.5" but that is just a guess from experience with EdgeHD 8)
 

 

For binoviewer use, the Glee goes between the diagonal and the binoviewer.  To configure it the way Baader recommends, you need a T2 diagonal, a short T adapter, and a T2 40mm extension tube. 

 

Almost for sure are going to be an aperture reduction with almost any kind of reducer though.  Even with a Mark V, my EdgeHD started to loose aperture with 170mm of flange to focal plane distance and this was without a reducer.  

 

Now that only matters if it matters to you I suppose, but to answer your question, the Glee goes between the diagonal and the BV.  It is mounted inside the extension tube.

I thought it went into the baffle tube according to its description.  If it goes into the baffle tube, will it interfere with the Edge correcting lenses?  

 

Nevermind, that attached file explained it all.
