I'm not sure how relevant my input is for you Bob since I am using a Starlight Xpress AO OAG unit with a Lodestar X2 for a guide camera on an RC12 with .8 reducer for 1960mm. But in case it is useful, this set of OAG hardware has been working perfectly with SGP and PHD2 and producing excellent and reliable tracking. It has never failed to find a good guide star in its field of view. So the communication between SGP and PHD2 is right on.
