We offer knobs for all versions of the Meade 8” f/10 and f/6.3 Schmidt-Cassegrain secondary, including those with three, four, and six secondary screws. (The extra screws on the four- and six-screw versions are for secondary disassembly, not collimation.) Select knobs for your telescope from the list below. Please use care to select the correct knobs for your telescope. Each knob set is different and they are not interchangeable. Price is for a complete set of knobs.
Fits: Meade 8” (20 cm) f/10 SCT versions with four screws on the secondary housing (LX90, LX200, others).
- Two sets of knobs, each with a different screw thread length, are included with your order. Use the thread length (measured below the white spacer) that matches the factory screw thread length.
- The factory dust cover should fit normally with Bob's Knobs installed. If your dust cover contacts the knobs, we provide a set of spacers that attach to the inside of the dust cover to move it slightly away from the secondary assembly. Contact us for a free set. You can also press the center of the cover from the inside to contour it for additional clearance.
- Pre-2005 Meade 8” telescopes have three screws on the secondary housing and no fourth screw on the side. The surface of the 3-screw secondary is textured, not smooth like the surface of the 4-screw secondary pictured. The 3-screw secondary requires different knobs (Item A above).
- An Allen wrench for removing the factory collimation screws is included with your order.
