Product Info

Manufacturer Description

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: AT12RC
Fits: Astro-Tech 12" RC secondary.

Knobs: Black plastic, 16 mm (5/8") diameter
Threads: Stainless steel

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