I received my SkyGuider Pro with iPolar last Friday. It's been cloudy over the weekend, so I didn't have much chance putting the mount in action.

Finally the clouds parted this evening, so I set up the mount polar aligned, pointed my scope to Mirach. Took a few 10~30 secs subs hoping to see

reasonably rounded stars but, to my dismay, found star trails.

 

Now it could be that my PA is not perfect, however, I suspect the mount's RA motor is not slewing. I am saying this because the mount has two buttons

that allow you to fast slew the RA axis. But when I press either of the buttons, nothing happens. I can't hear the motor moving. I have also tried motor

calibration, following this post, which slews RA clockwise and counterclockwise for 8mins each. The mount did not slew at all. 

 

Before I send the mount back, is there anything I might have missed? I would appreciate your thoughts/suggestions/comments. Thank you!

Okay, the tracking issue is resolved.

 

I searched SkyGuider Pro tracking issues on CN, came across DubbelDerp's post. Turns out my mount has exactly the same problem.

I opened the enclosure and turned on the power. The RA motor, as I suspected, did not move. Following DubbelDerp's steps, I tried to

block the optical sensor, and Voila! The RA motor started to move! After re-calibrating the motor (took about 16 minutes) and a few

power cycles, the mount seems to function properly. If the weather permits this evening, I'll do a few test shots to verify.

 

For reference, these are SkyGuider Pro motor calibration steps from DubbelDerp's post:

  1. Make sure the unit is off.
  2. Power on the unit while holding down the center button.
  3. Release the button to initiate an 8-minute slew in one direction.
  4. After the previous step is completed, press the center button again to slew the RA axis for 8 minutes in the other direction.
  5. Switch off the unit, and do a few power cycle.

Thanks!

Guess I'm lucky the issue can be solved easily, and I didn't have to return or send it back for repair.
