Bobs Knobs - KNOBS FOR CELESTRON 5 inch (13 cm) f/10 SCT WITH STANDARD 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 5) with black Allen, silver Allen, or
silver Phillips factory collimation screws. Will not fit scopes with black Phillips factory
collimation screws.

Knobs: Black plastic, 13 mm (1/2 inch) diameter

Threads: Black anodized aluminum alloy

Note1: These knobs will fit all 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 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.
