Thanks Peter. Its been so long since I've used the Newt the penny has dropped I've got one of my own here somewhere

- used to drive the Orion/Skywatcher cheapy motor on my Crayford.
I don't really want to disassemble the working adaptors etc on the Newt. Does anyone know where you can source a reasonably priced stepper motor? Any need for gearing? (looks like you have a large step down there anyway David going from the small motor cog to the considerably larger lens grip.
More questions - is it really a servomotor, not just a normal motor? I thought servos had encoders etc built into them?
