You should not be inducing ra corrections when you do a dec correction..what
could be happening is that the st4 is not aligned properly with the axis of the
mount. When you do a track calibration, all you want to see is pure movement
along the x-y axis of the guider...I don't think it matter too much but you are
making the st4 and mount work harder if the st4 head is not aligned with the
mount.

- Minimize dec corrections. I am not sure how to do this with the
ST-4, but in Maxim I only correct in Dec for pretty large errors, on
the order of 0.5 pixels. Dec corrections do induce an RA movement, so
minimizing is best.
