Bob's Knobs for Celestron C5 with Metric Collimation Screw Threads
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.
These knobs will fit only 2006 and later C5 models that have black Phillips factory collimation screws. All C5 models made prior to 2006 and all post-2006 models with silver factory collimation screws require C5 standard knobs. Check that the screw threads match the factory screw threads before installing.
Some telescope versions have a small plastic cover over the factory collimation screws. This cover must be removed and set aside when Bob's Knobs are installed. The cover is cosmetic only and will not affect operation of the scope.
C5met Fits: Celestron 5 inch (13 cm) f/10 SCT (C5, NexStar 5SE) with black Phillips factory collimation screws. These screws have metric threads.
