Well this was a weird set of experiences. If you connect CDC via ASCOM to the Plain Old Telescope Hub, yes go to's work, and yes nudges work, but the position of the scope in CDC doesn't update - which is really annoying!!!!!!!
The first go I was pointing at Spica but CDC was sure it was Raselhague, and nothing I told it could convince it differently. Not even a sync helped. From CDC disconnect the scope, re-configure it from POTH to SS2K and re-connect and all displays of position and goto's were fine - just no nudging!
I'm getting closer but still no ultimate joy!

Secondly looking at PHD I see stars jiggle every 10 seconds one a 3 star align once PHD is calibrated and tracking with a 1 second adjustment period. I presume I'm 1/2 a degree off polar alignment (guess) and with a 3 star align the Atlux is running motors correctly to self correct - but this interacts with PHD correcting in a haphazard way. I tried lower PHD's guide interval and RA component - but it didn't help much.
Tomorrow I think I'll do a 1 star align and then properly drift align things - which I'm only marginal at.
