On a 14-inch Schmidt-Cassegrain, the collimation screws of the secondary mirror are far from you, right in the middle of a large corrector plate. Getting to work on them with a screwdriver isn’t very pleasant. With these adjustment screws for a 14-inch SCT f/11 from Bob’s Knobs, you adjust the mirror with your fingers.
This is the execution set screw for the 14 inch f/11. Check beforehand how the secondary mirror of your telescope is attached and which screws are included. You can find this type of viewer in the Schmidt-Cassegrain telescopes.
Replace the screws one by one and then collimate on an unfocused star. If such a large tube is often mounted, then a protective case for a 14 inch SCT dust and dirt outside.
If your 14-inch desk has six free-standing screws, then you have the set for six free-standing screws needed.
