I don't own an SCT, but don't observers, "lock down" the mirror, and rely
on external digital motorized focusers.
That would eliminate mirror flop, in that case.
I hope that some day, the ASCOM driver will have an "orthogonality correction
factor" Table, for use with several swappable OTA's, and DSLR's which might be
attached to a mount.
