when you say autoguiding to 1x, did you mean sidereal rate at 1x?
did you have a guide camera and the st4 cable connected?
the idea is that you can keep tracking at sidereal rate, but not use auto guiding to monitor drift.
also remember, you must only look at drift in Dec and not RA. ignore all RA errors for both the meridian star and the East/West star.
Also, don't look at PEC just yet. try and practise drift alignment and get your polar alignment as close as possible. that will make a huge difference with imaging, and with goto's. guiding becomes so much easier.
so a good polar alignment is like a pre requisite.
