Ad Astra Observatory

What is the sound of no relays clicking?

I tried some unguided tracking tonight and captured the data so I could see what’s up with my mount.

I had to find a star bright enough to calibrate but dim enough to guide on. Did the calibration routine, then set RA aggressiveness to 0 once everything settled.

This is the data I got out:
Tracking only data

There is a steady (negative, leftward, which I interpret as “Eastward”?) drift in RA that reached 10 pixels max, 7 pixels RMS over the course of 40 minutes.

This data should give some indication of the smoothness of the PE curve, but also I believe there’s some bad in there about the motor controller running too fast or too slow…
