We offer knobs for all versions of the Celestron 14” f/11 Schmidt-Cassegrain secondary with Allen collimation screws, or either standard or metric Phillips collimation screws. 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.
- These knobs will also fit the Celestron 14” SCT with “Trifid” Fastar secondary and headless set-style collimation screws. The rotary secondary cover must remain open when knobs are installed. The cover is cosmetic only and will not affect operation of the telescope.
- The factory dust cover will fit normally with Bob’s Knobs installed.
- Do not adjust the center screw if present; this is the secondary pivot screw.
- The Celestron 14” SCT uses either standard 6-32 or metric M3 collimation screws. Headless set-style and silver Phillips factory collimation screws have standard threads. Generally black Phillips collimation screws have metric threads but a few have standard threads. If you order knobs with the wrong screws, contact us using the link at the bottom of this page for return instructions.
