Bobs Knobs Meade 8" SCT f/10 Collimation Knobs 6 Secondary Screws M8-4


Bob's Knobs for Meade 8" f/10 SCT with four secondary 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.
