"When tracking I have the gemini in Visual Mode. I'm tracking using GuideDog and a webcam, interfacing to the scope through the standard RS232 connection not the autoguider port, so as I understand it (and have seen from experimentation) the mode doesn't matter for this... Yet to really get the hang of this setup (guidedog with webcam to gemini) though, still new at this."
I have just re-read this, not having tried this at all but what about your guide speed, I know that for normal autoguiding it should be around 0.8 or 0.5, have you changed that when you are autoguiding through the RS-232 port. Maybe there is over-correcting which is causing your RA drift.
When you use the autoguider port and when set to Photo Mode, the guidespeed is automatically reduced.
Just a thought.
