About the Bob''s Knobs Celestron C11 f/10 with Flat Secondary Housing and 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: Silver factory collimation screws usually have standard threads, but some silver Phillips screws have metric threads. Be sure to determine which screws are on your telescope. 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.

 

Celestron 11" SCTs manufactured prior to 2006 have standard collimation screw threads.
