how to maka a telescope turn with high precision?

Hey everyone, I'm preparing myself because I need to build a project next year and write a thesis about it. My project is an automated telescope. Now I was wondering how I could turn the telescope around with some kind of motors at a precision of at least 1 degree. Has anyone experience with this kind of stuff or someone who has an idea?

Hi Simon,
For the Azmuth a clock motor would be better than a stepper as you will see a quantized step with the stepper and the clock motor would be able to track smoothly.

Can you provide a link to a "clock motor"? I haven't explored those.

Here is a link to the wikipedia page on hysteresis synchronous motors. These motors are commonly used in clock mechanisms and timers that use mains voltage for power. I have seen similar type motors used in azimuth drives on telescopes so that they can track contra the rotation of the Earth. I called it a clock motor as it will have to be precise enough to to maintain telescope position against the rotation of the Earth particularly if timed photos are to be taken.
