I didn't design it, I just worked out the ratios from the published step size.
A drive that uses a gearbox can go to much smaller step size however they have designed the system without a gearbox to get rid of the higher frequency periodic errors.
With the published payload, the mount could at most support a short 20 inch OTA. Theoretical resolution is 0.25 arc sec but seeing will almost always push the resolution much higher. I doubt you'd see the image cogging.
