First, the two inch focusser is overkill for the stereo...the prisms are
not large enough to completely avoid vignetting even with a 1 1/4 system.
If you can find one of the Tuthill variety, which I think is no longer on
the market, they had the largest prisms that Iever ran across. Then, all
you will need is a 2" to 1 1/4" adapter and as many pairs of plossls as
you feel appropriate. I found that with a C-8, I used the 17mm plossls
more than all of the other pairs put together. I think that Celestron
sells a stereo adapter that screws on the back plate but I have no idea
about the quality.
