Hi folks, I recently became the proud owner of a Nexstar XTL GPS 9.25" telescope with a number of extras fitted. This telescope is a bit of a jump for me but I'm getting to know my way around it. Among the extras it has the Celestron Focus Motor (#94142) fitted.
My question is about the limits of the focuser both 'in' and 'out'. mine never seems to stop when I hold the button down on the controls to focus close say on a nearby tree, or in the other direction on a a distant object. If I hold the button down the motor seems to go on buzzing away. When it gets to its limit is there any indication?

Sorry can't help with that one geoff as no experience of it but why not ask at next meeting where there is some discussion after the TOM assuming no observing of course. Jim

I have posted about this many times, and I use the JMI, have you asked Celestron, their reply is
The Celestron scopes have a STOP at each end of the focus so no harm is done they will STOP when the mechanics hit the end stops.

That is interesting and re-assuring. I'll must have another 'play' to see if I can find the end stops. Here is mine:

I was concerned when I wanted to fit one to my edge HD so contacted Ceklestron who told me that there were fixed hard stops at each end of travel and also confirmed that all their optics are 1/4PV
