They are designed for SCTs so they are not exactly low profile. How much back focus do they require ?
Will a MPCC fit inside (from both ends) ?

In all honesty, I don't think it will work, well not without a lot of mucking about.
The Celestron OAG I have is old, and basic, very basic.
It has an SCT threaded ring on the front end, this designed to attach directly to the rear cell of the SCT, so a 50mm thread. On the other end is the standard male T thread, 42mm.
Work it out for yourself, whether it will work or not, but to fit the MPCC to the front will require an adaptor to accept a male T thread, and have a male SCT thread on the rear. Fitting the MPCC on the rear side gives back space issues as this back space is already used up in the DSLR body.
Sorry, looks like a dead duck.
