Does the QSI allow raising or lowering the pick off mirror?, this can affect asigmatism and focus.......... (oops, as Gary mentions). If not, and the guide cam is too close, can you just pull the guide cam out a bit and reclamp. If not, make a spacer?. I have also found, out of focus guide stars are fine, but being eggy is a worry.
