Ah, okay. I thought I had read something about a closed loop system where encoders were used to pick up tracking errors with high end mounts when I was researching the upcoming eq8. I probably had is back-asswards as is often the case!

If it had to be one arcsecond, would that mean an encoder of 1,286,000?
