Bob's Knobs Meade 8" SCT Collimation Knobs For 4-Screw Secondary Holder

  • Bob's Knobs Meade 8" f/10 SCT versions with four screws on the secondary housing include LX200, LX90, others
  • Bob's Knobs are a black plastic material of 13mm in diameter
  • The Bob's Knobs Meade 8" SCT f/10 Collimation Knob threads are a black anodized aluminum alloy
  • Included in your Bob's Knobs order is an Allen Wrench for removal of factory collimation screws

Provided with your Bob's Knobs Meade 8" SCT f/10 Collimation Knobs is a set of spacers. Attached to the inside of the dust cover on your telescope. Your meade factory dust covers may contact the knobs when installed so these spacers attach to the inside of the dust cover to move it slightly away from the secondary assembly. For additional clearance, press on the center of the cover from the inside to contour it.

Pre-2005 Meade 8" models have three screws on the secondary housing and no fourth screw on the side. The three screws on the secondary housing require different knobs because the surface of them are textured instead of smooth.
