Celestron Focus Motor 94142

[Geoffw]

I have recently acquired a used Celestron Nexstar GPS 9.25" Scope that has fitted the Celestron Focus Motor (94142).

I have one niggling worry that I am hoping someone might re-assure me about.   What happens when you get to the end stop either focusing  near or to infinity?   Should the motor stop or should the sound of the motor  change to give you a clue.? Can you do any damage to the scope or the Focus Motor if you  keep it running after the end stop has been reached?

Some comment or advice would be appreciated.

Might be worth taking the focus motor off and do a manual in / out to see what happens. My EDGE HD8 definitely 'feels' different at each end of travel
