Product Details

  • Now there is 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: These knobs will fit only the Celestron 8 SCT with Fastar secondary and EdgeHD optics. These telescopes are marked EDGEHD OPTICS on the corrector ring. Do not use these knobs on the non-EdgeHD Fastar secondary; the screws on these knobs are too long. It is important that you choose the correct style Bob's Knobs for your telescope. Please note the number and type of screws on your secondary housing before ordering. The factory dust cover will fit normally with Bob's Knobs installed.

I wish Celestron would have thought of this

These screws make collimating my Edge HD 8 easy peesy. They are easy to install and easy to use. I really like the idea that I don't have a pointy, Phillips screwdriver any where near my corrector plate!
