Problem(s) Encountered:

While observing the telescope run into the pier interlock (my bad).  A dedicated entry in the telescope manual on how to bring the telescope out of such a situation would be very welcome... I ended up moving the telescope out of the interlock with the help of the TCP virtual paddle.

Solutions:
