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?

There are many examples of automated telescopes with open source designs and software available with a websearch.

Depending upon what you are doing, you will need much better than 1 degree accuracy.

The stepper motor approach is probably the cleanest, though you might want to add a star tracker camera to get smooth tracking on star targets.
You will also need to account for sun, moon, planet and comet tracking.
For Asteroids you usually need time exposures, so you use the star trackers.

The timing issues are fairly straight forward depending upon your telescope mount.
Are you using an Azimuth/elevation or equatorial mount?
