"Some "extreme" modifications required the telescope optics be moved 48.5mm closer together so that an attached camera and its adapters would easily reach the telescope's prime focus"
recently, i re-collimated my secondary with a piece of paper between the primary and secondary. the visual side of things is great, but now i can not use my toucam in prime focus. the focus is further in towards the secondary so to speak.
I remember when i first got the scope, the same thing happened. i fiddled back them with the secondary and the prime focus then worked as it was now in the range of the focusser. reading your excellent website again and this jogged my memory.
did you move your primary 40 odd mm up the tube towards the secondary??
i believe that i may be in similiar strife with a canon 350d down the track.
with a 2.4x barlow i have no problems, focus is right in the middle.
