Hi,

Yup it will track in both RA and DEC if the polar alignment is off and you have done 3 or more align stars. I am talking from memory here so I am not 100% sure (sold my Sphinx a while ago) but I seem to recall you cannot turn this feature off so, for AP work, it is best not to do more than a 2 star alignment as you do not want the mount moving in DEC and possibly fighting against your guiding. I think this will apply to any Vixen mount driven by the starbook - not just the SXW/SXDs. BTW I found the DEC backlash to be so large as to make AP very difficult (mind you I had a VC200L on it) but that is another story....
