Bobs Knobs - KNOBS FOR CELESTRON 5 inch (13 cm) f/10 SCT WITH METRIC COLLIMATION SCREW THREADS

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

It′s easy . . . just grab a Bob′s Knob 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.

Fits: Celestron 5 inch (13 cm) f/10 SCT (C5, NexStar 5SE) with black Phillips factory
collimation screws. These screws have metric threads.

Knobs: Black-oxide steel, 12 mm (1/2 inch) diameter

Threads: Black-oxide steel

Note1: 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 our screw threads match the factory
screw threads before installing.

Note2: The factory dust cover will fit normally with Bob′s Knobs installed.

Note3: 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.
