Bob's Knobs for Celestron 5" f/10 SCT Standard
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 Bob's Knobs will fit all Celestron C5 models made prior to 2006, and all 2006 and later models EXCEPT those with black Phillips factory collimation screws. The black Phillips screw model requires C5 metric 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.
Fits: Celestron 5 inch (13 cm) f/10 SCT (C5, NexStar 5) with black Allen, silver Allen, or silver Phillips factory collimation screws. Will not fit scopes with black Phillips factory collimation screws.
