Phil it looks like there is about 13 arcsec error. I suppose I could say +/- 7, but since I started the run with the track at its lowest point, all variation was upward. That was plotted 'as is' The plot while PEC training seemed to be mostly about 4 arcsec with a few minor indiscretions. Then something went batty; the Dec trace looked like about 30 on the richter scale! I wonder if I pay the registration fee, will K3CCD behave? The star image stayed still, the white square box was jumping up/down all the time.
After things were restored to normal, I replayed the PEC training but the error was still about 13 arcsecs, So something I'm doing is wrong or else there is a problem with the Firmware in the Controller.
Guiding gave reasonable tracking, though there were a few sharp rises and falls, this can probably be refined with adjusting aggressiveness.
Cheers,
Doug
