Paul, whole unit was supplied by Zhitong, and I have written to them to ask what to do. Whilst they have acknowledged my email, they have as yet offered no advice.
The controller says it is a "QHY STEP MOTOR CONTROLLER VER 1.3" and the stepper motor is an "EM ST30/ 12VDC, EVER MOTOR, 500 ohms".
I have opened the controller box, and there is no switch inside, (that probably means it isn't a Losmandy in disguise )
I have attached a few shots of the equipment, in case it means anything to anyone, but I can't see that it's likely to help much.
Thanks for the suggestions though, keep 'em coming. |
Could this have been made by the same QHY that now makes CCD cameras. It might be worth asking him. He is very helpful and can be found via
