I would think the center of rotation would have to be North (or South)
and every thing else would be set up for that. It is with the PST-61.
I'd be a bit upset with a system that didn't do it that way. That way
it has the same amount of overlap on each end of rotation for a total of
540 degrees. It has 90 degrees overlap on each end of rotation which
I've found to be very handy. However I have the digital readout which
doesn't tell me which end I'm past. OTOH it's smart enough that if I
input a heading er...bearing and it's past the overlap it'll turn around
and go the other way.

Been there, done that with the PST-61 which uses a 10 turn pot for
sensing. I was very careful about marking and documenting, but the
alignment still turned out to be a bit more time consuming and work than
I expected.
