Thanks for all the tips.
Paul, I plan to take another TPoint model tonight (weather remitting of course) and then see how it goes on successive nights. A new daily build was released last night so I'll try that too.
It was very off. PEC and Protrack were both off - for example, PEC was out of phase making images much worse. I rehomed and that seemed to fix the phase.
The drift in RA is constant irrespective of the direction I am pointing.
I can't do anything visually during the day - its up at Coona. I have however switched over the RA and Dec worm assemblies. If that fixes it, the problem is with the worm. If it doesn't, it may be firmware, corrupt T Point model, dicky TSX install etc etc.
Will let you know how it goes
Pete
