Hi Avalon,
great to see you announcing a harmonic drive mount! Can you provide some more details?
Regarding the motors you write: RA/DEC motors200 stepper motors
What does that mean exactly? The HQ motors for the m-zero for instance are listed with 400 steps - how does that compare?
Another point is this:RA resolutionUp to 0,11”
Again a bit unclear how that relates to other mounts. May be you can tell us something about the expected periodic error? Sharing PHD2 logs would be awesome of course.
Does the mount support setting limits to minimize the possibility of any damage that might be caused by the strong motors?
Thanks in advance
Stephan

Nice mount indeed!
Another bit of useful information would be to know if the HM1 has brakes on both axis or only on the RA one. Having brakes on both axis would be nice to park the mount away from home position.

Hello
The difference are the number of steps per turn. In theory the more the steps, the higher the resolution but in this case they are hard to compare because we are speaking about two different technologies.
More information about the guide test may be released later.
The mount is controlled by the StarGo Plus which support the RA and DEC limits.
On the mount is available the brake on the RA axis, the DEC balancement is more easier to have and a small unbalancement would not be a great issue.
Best regards
