About the Bob''s Knobs Celestron C11 f/10 w/ Flat Secondary Housing (non-Fastar) & Metric Collimation Screw Thread...

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: Black Phillips factory collimation screws usually have metric threads, but some black Phillips screws have standard threads. Make sure the knob threads match the factory screw threads before installing the knobs.

 

The factory dust cover will fit normally with Bob'''s Knobs installed.

 

If your telescope has a factory-installed plastic cap over the collimation screws, it 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.
