how to maka a telescope turn with high precision?

simon.ganne

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?

  • thanks for the replies but I need a way to motorize it. anyone an idea?

    If you google “diy motorized telescope mount” or something similar you will find lots of examples.  Also check astronomy forums.  In my opinion, the motor is the easy part.  The mount and mechanical parts, especially for a large telescope can be challenging.

     

    I have stepper motors with worm gears on my telescope with a german equitorial mount.  I also made a “barn door” mount once for my camera that was driven by a stepper.  This is a very easy mount to make and It is relatively easy to maintain one degree precision over an extended period with such a setup.  Google...

     

    BTW, It isn’t clear to me whether you are trying to find a spot in the sky (slew) with one degree precision or track.  Tracking only requires one motor for one degree precision over moderate timeframes with an equitorial mount and finding requires two.
