A bit more detail - its becoming a battle of pointing versus tracking.

If I switch on the mount and only align it on one star the RA tracking seems fine (but gotos aren't as accurate as I'd like). However if I add one or two more stars well when I slew to these targets a small adjustment in pointing is required (say 4 degrees in RA for star 2 and 1 degree for star 3). After adding just the second star I notice drift in RA appears. Perhaps this small delta changes the tracking rate by adjusting how the hand controller allocates angular distance to the gears?

So I am wondering if this calculation of sky pointing model changes the accuracy of the RA tracking - even in polar aligned mode - any thoughts on what is happening and how to fix it guys?

Thanks!
