Bob's Knobs For GSO 12" Ritchey-Cretien Secondary


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.

Notes 1: The factory dust cover will fit normally with Bob’s Knobs installed.
