Bob's Knobs for the Meade 12" Lightbridge Primary Mirror
Now there is no more tools needed to make collimation adjustments to your telescope! It's easy . . . just grab a Bob's Knob and turn. You can even collimate while looking through the eyepiece on most telescopes. What's more, you'll never drop that pesky little Allen wrench or screwdriver in the grass again. Installation is a snap with included instructions, and you can undo the modification at any time.
Fits: Meade 12" (30cm) f/5 Lightbridge primary mirrors. Knobs are also available for the secondary mirror. See the "accessories" section for more information. It is important that you choose the correct style Bob's Knobs for your telescope. Please note the number and type of screws on your secondary housing before ordering.
The telescope optical tube assembly will clear the rocker box with primary knobs installed.
One of the primary mirror knobs may interfere with the cooling fan connector. The plug will fit properly between the knob flutes (see photo in "Images/Articles" tab), so leave this one knob stationary and collimate using the remaining knobs. If desired, you can leave the factory collimation screw that is next to the fan connector in place.
