My question: how do you save the current pointing direction in Sitech and return to it after slewing to focus?
I can't find the answer in the Sitech manual, not that that means that it is not there.

I don't know about your exact hand controller but mine use " user object ". Set it once the subject is centred then slew back and forth as you please.
