Something bad happened shortly before 22:47, a huge excursion in RA that caused the total RMS to reach 2.6 a-s for the time period shown. But the guiding before and after that event looks much better. You can use PHDLogViewer to isolate those regions to see how things were going. When...

so I tried it again unguided. And yes there is now a very narrow monotonic peak at 12.09s with an amplitude of 3.5". Here's the analysis in PEMPro log viewer this time (EQMOD was using the PEC file from last time):
I am using pulse guiding, with my mount directly attached to the Raspberry Pi 4 (KStars/EKOS) with a USB cable. No ST-4 cable, so PHD2 knows exactly where it's pointing (also proven by the RA/DEC values recorded in the log file for where the calibrations are taking place). Is t...
