Gooday Aidan,
As far as multi-star guiding goes, on Google Groups under the PHD2 forum, they have been experimenting with multi star guiding.
News is not too good, If you only had mediocre stars to guide from then multi-star was better than a single star, 20% better FHWM, however a single decent guide star was better than multi-star.
But its early days with their experiments.
Just remembered you had to use a guide scope for multi-star, cannot use OAG, not enough separation of stars
Regards
Bill
