Thanks for that Dennis. A beautiful setup indeed. You've just cleared it up - I need the 1.25" diagonal instead of presuming that the 2" would take care of everything by itself. I take it that a cheaper GSO dielectric diagonal would work the same as the WO?

Cheers

As stated previously, focus could not be achieved using the WO SCT threaded 2 inch diagonal which is used for visual observation.

There may be some slight advantage having the camera mounted thus, as its own weight and the weight of the cables is less likely to pull it from the diagonal, compared to a straight through position?
