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: C14set
Fits: Celestron 14" (36 cm) f/11 SCT versions with factory headless set-style (Allen or slotted) collimation screws

Knobs: Black plastic, 19 mm (3/4") diameter
Threads: Black anodized aluminum alloy

Notes:
1. The factory dust cover will fit normally with Bob's Knobs installed.
2. These knobs will also fit the Celestron 14" SCT with "Trifid" Fastar secondary and headless set-style collimation screws. The rotary secondary cover must remain open when knobs are installed. The cover is cosmetic only and will not affect operation of the telescope.
3. Do not adjust the center secondary screw if present.

      Cons:

      Comments:

      I WORKED TIME AND TIME AGAIN TRYING TO COLLIMATE WITH THOSE SCREWS FOR 2 HOURS. BACK AND FORTH BY MYSELF. STILL NO LUCK. SEEN THE ADD FOR THE BOB KNOBS. HAD THEM IN 3 DAYS. INSTALLED THE 3 KNOBS IN LESS THE 5 MIN. TOOK LESS THEN 10 MIN. TO COLLIMATE MY C14. SO I WILL HAVE THEM INSTALLED ON MY C11 C8 C5. FOR THE LOW PRICE YOU PAY FOR THEM TO PUT YOUR SCOPE THE WAY IT WAS MADE TO WORK. NO BRAINER.
