Bob’s Knobs for the Celestron 6″ SCT

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: All Celestron 6 inch (15 cm) f/10 SCT versions (C6S, C6GT). 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.

Since the factory dust cover contacts the secondary housing when installed, additional clearance is needed to make room for the knobs. We provide a set of spacers that attach to the inside of the dust cover to move it slightly away from the secondary assembly.
