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: C8hyp
Fits: Celestron 8" (20 cm) f/10 SCT with metric collimation screws and Hyperstar option.
Knobs: Black oxide steel, 12 mm (1/2") diameter
Threads: Black oxide steel
Notes:
1. These knobs are taller than our other metric knobs to compensate for the countersunk factory screws in the Hyperstar secondary.
2. The factory dust cover will fit normally with Bob's Knobs installed.
