About the Bob'''s Knobs Celestron C5 f/10 Secondary with Standard Collimation Screw Threads...
Collimate your Schmidt Cassegrain Telescope or Newtonian Reflector Telescope without tools when you use Bob'''s Knobs!
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.
Note: 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.
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.
