Default No way to reach focus with C9 with binoviewer and reducer?

Hello experts,

was anybody in this big wide world successful to reach
focus with this setup.

My attempts with a Celestron 6,3 reducer/flattener and
a Baader-Widefield-Binocular were unsuccessful by far.

Any suggestions?

Thank you very much,

Reinhold

Hi:

The easiest solution is to use the Denkmeier Starsweeper. Reasonably priced,
good images, and it can be threaded directly onto the binoviewer (if it has a
2" nosepiece) or onto a 1.25"/2" adapter. The Starsweeper also works very well
for single eyepiece viewing. It's more convenient to use if I think I might
want to switch back to f/10 over the course of the evening, so I rarely use the
Celestron Reducer/Corrector any more. For the 6.3 r/c you have to work, you'd
have to rig some means of reducing the spacing between it and the binoviewer.
