Hi Wildi,

In order to illustrate a bit more the problem I took some pictures of all the sequence of actions that I carried out as you suggested with the GTO CP2 driver. I numbered the actions so that you can follow what I did, and see the result.

1. This picture shows shows the Parking position when the driver is started and the connection is established (in WIndows I would normally use the Parking Position 3).

2. I set the mount as you suggested, as if the telescope was pointing East, and synchronised the mount at that position.

3. I sent the mount somewhere in between the E position and cenit.

4. This picture shows that the mount seemed to do its job correctly, and the scope was sent approximately where it had been sent.

5. Then I selected an object closer to the meridian, in this approximately Aldebaran.

6. This picture shows that the mount flipped its side and went to Aldebaran but from the other side. The mount did a Meridian Flip before it had crossed the Meridian.

7. According Kstars, the scope was indeed pointing to Aldebaran.

8. I finally sent the mount to park, and this is how it ended.

I also sent the log that should show you what the mount did. The Experimental Driver seems to work but not always (it occasionally reminds me that my CP2 does not support "Rev V"), but it produces similar results.

Thanks for your help,

Josep
