Spid MD-01 tracking the Moon using a Slew Drive. Using PstRotator
The Moon is not visible yet and below the horizon.
It's way below the horizon but the elevation is cycling every 30 seconds or so up to about 1.1 degrees and to 0.0 degrees where it ought to be.
When it is tracking above the horizon, then it cycles both up and down about +/- 1.1 degrees.
Also it only updates every 30 seconds but PstRotator is set for both Rotor and Tracker to update every 1 second.
See the changes at 10 seconds in, 42 seconds and 1:14 ?

A summary :
· I bought the Spid MD-01 because it will operate a slew-drive at 0.1 resolution
· I bought it because it worked with PstRotator
· I bought the Spid absolute sensors giving 0.05 degree resolution
· I bought it to track the Moon and low orbital and other satellites
· I am currently testing it on the very slow moving Moon using the built in internal tracking of PstRotator

· PstRotator is set for both Rotor and Tracker to update every 1 second.
· The Azimuth is correct to 0.1degree
· The elevation always cycles about +/- 1 degree
· The updates are every 30 seconds not every 1 second
