    Hi - I have an ST10XME in a 14" SCT and used to have an ST200oXM. I would use the ST2000XM in an 80mm piggybacked refractor for autoguiding (Losmandy Gemini 2 system). I never had any problems autoguiding with this setup.

    Now, however, I recently purchased a QSI 683 CCD which I'm using in the refractor. I tried to use the ST10XME for autoguiding (tracking is good but wanted more precision with widefield shots). I am having a tough time now. The ST10XME won't calibrate and the guide errors are way off - especially in the x axis - off by 15+ pixels. I've tried 1x, 2x binning and still no luck. The guider cable is in the correct port in both the camera and the gemini controller...
