Thank you very much for taking a closer look.

Technically and in order to answer your questions, it is the same controller that manages the telescope and the dome. The ASCOM driver is well written in java so it handles everything at once. It also does, if one wishes, the synchronization of the dome with the telescope. I had already asked you about this point (how to manage the geometry).

I totally agree with your analysis: the dome connects, but for some unknown reason the polling is not done. The issue is then between these two steps. The error may very well come from this new ASCOM driver and the difficulty is to identify the step that causes the problem, knowing that the problem comes from time to time and that I can't (yet?) reproduce the conditions (this would be easy to solve in this case).

I will check with Michael and install the Pipe to get more elements. We're going to get it right!
