The Vixen SkySensor2000 will track and point in polar unaligned mode and run both motors accordingly.
My sense is to do this really well you need something like Tpoint or Maxpoint that model several tens to hundreds of stars and can determien alot off seeing and mechanical limits to your gear (e.g colimiation, axes mis-algnment, tube droop etc) as well as pointing alignmnet, backlash and other errors - quite hard to do.
To get long duration photography going I sense you need many of:
1) dark site
2) permanent pier
3) solid, high precision mount
4) excellent sky modelling software
5) feedback loops from imaging to pointing to racking and guiding analysis software
It would be great if it where all there and affordable!
