[AZ-Observing] Re: MSW inverters

you might want to search around and see if anyone has come up with a DC  
Servo motor replacement for the old AC Synchronous motor. If I still had my  
Quantum Six I would have done just that sort of thing.

Fellow  Stargazers,
I trying to find a way to power my old (ca. 1985) Orion drive  system 
remotely and lose the need for an extension cord.  It's a single  RA drive, 
with a 
synchronous 120 VAC motor.  What I'm wondering is, has  anyone used a modified 
sine wave inverter to power these things?  True  sine wave inverters are 
prohibitively expensive.  I'm concerned about  tracking accuracy, of course, 
and 
possible damage to the motor.  My  online search provided conflicting advice.
