I'm facing some issues using PHD2 with HEM15 under a good polar alignment...
On the mount side, the guiding rate was set to 0.90 for the two axis.

On PHD2 side, I got a lot of Dec Backlash, when doing the calibration:

With this setup

And after Guide assistant analysis

Any idea how to improve and what kind of setting are you using with Ioptron HEM series ?
