Bob's Knobs for MEADE 16” (41 cm) SCT

Bob's Knobs for MEADE 16” (41 cm) SCT

We offer knobs for all versions of the Meade 16” f/10 Schmidt-Cassegrain secondary, including those with three and six secondary screws. (The extra screws on the six-screw version 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.
