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 12 inch (30 cm) f/10 SCT versions with three screws on the secondary housing.
Knobs: Black plastic, 16 mm (5/8 inch) diameter.
Threads: Black anodized aluminum alloy.
Note 1: The factory dust cover will fit normally with Bob's Knobs installed.
Installation instructions are available in English, Spanish, German, Italian and French.
