Collimate your Catadioptric or Newtonian reflector style telescopes without tools!
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. These thumbscrews are also much easier to use with gloves on. And perhaps most importantly, 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.
Part: MLB10pri
Fits: Meade Lightbridge, GSO, Zhumell, Apertura 10" (25 cm) f/5 telescopes with factory collimation screws. Will not fit scopes with factory collimation knobs.

- Threads: Plated steel

Notes:
1. If your primary looks different from our photograph, or already has factory collimation knobs, these knobs will not fit.
