alandee, here is a quote from Chuck Reese over on the Yahoo Meade DSI group when asked about the set up of Focal Reducers.
Quote:
The 6.3 reducer is designed to be used with a lot more distance
between RF and camera...we usually mount it to the rear cell of the
SCT, then the microfocuser, then the camera.
The 3.3 goes behind the MF, with either 15 or 30mm extensions for F5
or F3.3, respectively. Using both extensions (45mm total) gives you
F3.0. All that said, when using the pro, you need to factor the 15mm
height of the filter bar holder into the mix.

I'm now not so sure about your 'clear' filter. What sort of threads does it have on the back? (I've had a look at the BinTel site and the Meade clear filter there does not have the SCT rear cell threads on it)
