  • David Astro Collimation Knobs for Celestron/Sky-Watcher Newtonians

    The David Astro Collimation Knobs for Celestron/Sky-Watcher Newtonians replace stock collimation screws so you can adjust collimation by hand, without a screwdriver or hex key.

    Tool-Free Collimation

    Newtonian reflectors need regular collimation checks. With knobs in place of the screws, adjustments can be made by hand at the telescope, with no small tool to find or drop in the dark.

  • What is the main advantage of these knobs?

    Tool-free collimation: adjustments are made by hand instead of with a screwdriver or hex key.

    Which telescopes do they fit?

    They are made for Celestron and Sky-Watcher Newtonian reflectors. Our product data does not list individual models. Contact us before ordering and we will confirm it for you.

    Do they replace the primary or secondary mirror screws?

    This is not stated in our product data. Contact us before ordering and we will confirm it for you.

    How do I install them?

    Replace the stock screws one at a time so the mirror stays supported, then recheck collimation.
