Getting to the front of a 14-inch tubeless tire with a screwdriver in hand is awkward, and you’ll be very close to the glass. With Bob’s Knobs for your 14-inch SCT, you replace the original screws on the secondary mirror with larger knobs so you can align the mirror by hand.
This set is intended for 14 inch Schmidt-Cassegrains with six screws that are visible on the secondary holder, so not under a cover. Compare well with your telescope before ordering. You can find this type of viewer at catadioptric telescopes.
Replace the screws one by one so that the mirror stays fixed, and then adjust the collimation to a bright star. A coated corrector plate helps against fogging. rainband for 14 and 16 inch.
