Digital Cameras Photo Reviews of Orion AstroTrack Drive for EQ-1 Equatorial Telescope Mount
Customer Review: Almost unusable
Summary: 2 Stars
When I first hooked up the motor and turned it on, I was surprised to see Saturn reverse course and head east. I had to tweak the speed control to try and match the sidereal rate. This wouldn't be bad if you only had to do it once, but it slows down as the battery wears out (which will happen MUCH faster than the 35 hours advertised). So you'll find yourself tweaking the speed control often.
The worst part about this motor is that it makes fine manual R.A. control impossible. There's no "clutch"--you can't rotate the R.A. worm gear shaft without disconnecting the motor first. But you can't reconnect the motor without first rotating the worm gear shaft so that its groove lines up with the thumbscrew on the drive shaft. So the only way to adjust right ascension with the motor attached is to loosen the R.A. lock nut and slew the telescope manually, which can be difficult at high magnifications.
