Fits:Celestron 5” (13 cm) f/10 SCT (C5, NexStar 5) with black Allen,
silver Allen, or silver Phillips factory collimation screws. These
screws have standard threads. Will not fit scopes with black Phillips
factory collimation screws (see Item B below).

Notes:
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 (Item B beolw). Check that
our screw threads match the factory screw threads before installing.
The factory dust cover will fit normally with Bob’s Knobs installed.
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.
