Bob's Knobs for MEADE 14” (36 cm) SCT We offer knobs for the Meade 14” f/10 (Item A) and f/8 (Item B) Schmidt-Cassegrain secondary with exposed collimation screws. These telescopes have six secondary screws. The three inner screws are for collimation. The three outer screws are for secondary disassembly, not collimation. We do not offer knobs for the very early Meade 14” f/10 Schmidt-Cassegrain telescope with recessed factory collimation screws (Item C). 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. _______________________________ A.
