SCT Collimation without Tools: BOB'S KNOBS
It's easy . . . just grab a Bob's Knob 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 on your corrector plate, or in the grass again. Installation is a snap with included instructions, and you can undo the modification at any time.
In particular, this model:
Fits: All Celestron 14 inch (36 cm) f/11 SCT versions with factory headless set-style (Allen or slotted) collimation screws.
Knobs: Black plastic, 19 mm (3/4 inch) diameter.
Threads: Black anodized aluminum alloy.
Note 1: The factory dust cover will fit normally with Bob's Knobs installed.
Note 2: These knobs will also fit the Celestron 14 inch (36 cm) SCT with "Trifid" Fastar secondary housing 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.
Note 3: Do not adjust the center secondary screw if present.
Installation instructions are available in English, Spanish, German, Italian and French.
