Bob's Knobs Meade 8" (20mm) Schmidt-Newtonian Secondary - MSN8sec

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

The knobs sit above the lip of the secondary housing for easy access.

The factory collimation screw 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.
