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 Meade 8 inch (20 cm) f/10 SCT versions with six screws on the secondary housing (LX90, LX200). The inner screws are for collimation.
Knobs: Black plastic, 13 mm (1/2 inch) diameter.
Threads: Black anodized aluminum alloy.
Note 1: The factory dust cover will fit normally with Bob's Knobs installed.
Note 2: Earlier Meade 8 inch (20 cm) telescopes have three screws on the secondary housing. These scopes require different knobs. Do not use knobs for the 6-screw secondary on the 3-screw secondary. The screws on these knobs are too long.
Note 3: See our special instruction supplement for installing Bob's Knobs on Meade telescopes with six factory secondary screws.
Note 4: Some very early Meade 8 inch (20 cm) model 2080 telescopes have two collimation screws. Please contact us for knobs to fit this scope.
Installation instructions are available in English, Spanish, German, Italian and French.
