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\u2019t very pleasant. With these adjustment screws for a 14-inch SCT f\/11 from Bob\u2019s Knobs, you adjust the mirror with your fingers.<\/p>\n\n\n\n

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<\/a>.<\/p>\n\n\n\n

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<\/a> dust and dirt outside.<\/p>\n\n\n\n

If your 14-inch desk has six free-standing screws, then you have the set for six free-standing screws<\/a> needed.<\/p>","protected":false},"excerpt":{"rendered":"
