Can't help you with a Vixen mount but I can tell you the Gemini just requires a Warm Start and a synchronization on one star and all GOTO's will be spot on. All the relevant info is kept in the Gemini unit and power is supplied by a small 2032 battery and used on subsquent startup's.
I must add that my mount is some 10 arc minutes out in elevation and some 13-14 arc minutes out in azimuth since I re-mounted the G-11, so does that effect the GOTO accuracy, no, the Gemini builds an accurate pointing model to compensate
Mine is kept in a Home position with the OTA horizontal, on startup I just put the counterweight down and the OTA pointing south using the Gemini handcontoller, then Align Star, GOTO bright star, Sync, then everything carries on from there, takes all of 5 minutes (if that).
Cheers
