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. NOTE: 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.

Primary mirror springs as supplied by the factory can sag from the weight of the mirror cell. Our stainless steel replacement springs are stronger and provide adequate support to maintain primary mirror collimation. Fits 8", 10" and 12" LightBridge.

These knobs will fit only 2005 and later C8 models that have black Phillips factory collimation screws. All C8 models make prior to 2005 and all post-2005 models with silver factory collimation screws require C8 standard knobs. Check that our screw threads match the factory screw threads before installing.

No Tools Needed! 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 in the grass again. Installation is a snap with included instructions, and you can undo the modification at any time.
