Glad to hear this. I have been wondering about running Maxim via
POTH. I use an RCX.

The mount can handle simultaneous corrections - but I read somewhere
that POTH (or ASCOM) cannot!

My struggle is with the dec variation. With good alignment, I am
still finding erratic movements occur. I get a lovely straight patch
and then suddenly it drifts up or down. I cannot work out which way
is indicated for the drift; the corrections go +y at one time, but -Y
another! The suggestion of 'turn off correction in the direction
where..... whatever, does not help when drift seems to be random up or
