How do people rotate the ZWO OAG or do something else in order to find guide stars?
It appears that the ZWO OAG does not allow for rotating of the prism around the circumference of the image circle, unless i'm missing something.

there is a very small angle to rotate
how do you rotate within that small angle? i don't see any instructions or details on that
thanks

If rotation of the prism is limited, then finding a guide star is a challenge for really long focal telescopes.yet this is the very reason OAG is preferred to reduce flexture.
Hope am right in my comments.
