I've been calibration/guiding in Maxim at 0.5x since I was concerned
about what the minimum move time for the mount would be when doing
small corrections at the (relatively) high speed of 1x.
Running at 0.5x means the correction durations would be twice as long
as at 1x for a given guide star error.

What's the minimum move duration the mount (AP900) can reliably
perform at 1x?
Minimum move is around 8 milliseconds, which means this:
8msec = .008 sec.
1x = 15 arc sec per sec.
Therefore 8 miliseconds at 1x = .008x15 = 0.12 arc seconds.
