Yes, I did. But unlike your tutorial, I was not using SGP as my collection interface but connected to the camera directly. Also, when I did the calibration wizard I got very little movement away from the primary star trail -- why I was fiddling with the TVC setting. Changing TVC did make my sawtooth contiguous, but I noted your prior comment to disable it completely. So if I do have a backlash issue that interfers with direction changes and I disable the correction, now what?
