Product Details

  • Now there are no more tools needed to make collimation adjustments to your telescope! It's easy . . . just grab a Bob's Knob and turn. You can even collimate while looking through the eyepiece on most telescopes. What's more, you'll never drop that pesky little Allen wrench or screwdriver in the grass again. Installation is a snap with included instructions, and you can undo the modification at any time.

    Fits: All Meade 8", 10", 12" & 16" Lightbridge secondary mirrors as well as Celestron C6-N/NGT, C8-N/NGT, and C10-N/NGT secondary mirrors. Knobs are also available for the primary mirror. See the "accessories" section for more information. Please note the number and type of screws on your secondary housing before ordering.
