Can anyone help with finding a RA stepper motor for my older eq3 type mount? I'm sure it's similar to the older Astromaster CQ-2 or CQ-3 mounts
with 136 tooth RA worm drive wheel.
Every motor setup that i've found, so far, seems to be made for eq3 mounts with either 130 or 144 tooth wheels.
The last option that i'm aware of, is to find a stepper motor setup from Star Watcher made for their older eq3-2 mounts
and somehow modify the hand controller to change the motor speed that will suit my 136 tooth wheel.
I heard of other guys changing a crystal inside the box to change the speed, but not sure how to proceed in doing that modification.
