Henk,Not for this session but I will get a PHD2 log tonight.
Are you getting most of error on RA or on DEC?This time about 50% more on RA but that was also because I did not counterweight much. During my best run at 0.6" total RMS they were about equal.
Can you share your unprocessed stack? I can measure the PSF for you.I will put an Autosave.tif on my cloud space and let you know.
One more question, I can't find good references for the TMC2130's Vref. There was a calculator online that returned 1.27 V for my 0.9 Amps/phase (== Irms I think). Howard said to turn it down to half that, which I did. I would like to understand the effect on tracking accuracy. I will experiment tonight.
