COLLIMATE YOUR SCHMIDT-CASSEGRAIN STYLE OR NEWTONIAN STYLE TELESCOPE WITHOUT TOOLS

It’s easy . . . just grab a Bob's Knob collimation thumbscrew and turn.  You can even do it while looking through the eyepiece on most scopes. And you'll never drop that pesky little Allen wrench or screwdriver into the grass again. Installation is a snap with the included instructions, and you can undo the modification at any time.

We also offer knobs for no-tools setup of Losmandy and Celestron tripods. Check our mounts section for details. 

Try our custom knobs, where you can choose from a wide selection of screw sizes and knob styles for all your telescope thumbscrew and hand bolt needs.
