Omegon SCT Adapter Kit: 82.5 mm to 50.8 mm (C11 to C8): your Crayford focus on a C8 or C11<\/strong><\/h2>\n\n\n\n

Anyone who wants to bypass the mirror shift on a Schmidt-Cassegrain mounts an external Crayford focuser behind the SC thread. This bundle provides that connection for C11 and C8 telescopes: from the SC screw thread to the 78 mm ring clamp of the Omegon focusers.<\/p>\n\n\n\n

This is how you perform the coarse focusing with the main mirror and the fine focusing with the Crayford, without distorting the image.<\/p>\n\n\n\n

For both sizes in one bundle<\/h4>\n\n\n\n

The adapter bridge from 82.5 mm (C11) to 50.8 mm (C8) allows the same set to fit on both telescope sizes.<\/p>\n\n\n\n

The optical length is 34 mm. Behind a SC with a reducer, that is a measurement post; check the remaining working distance of your setup.<\/p>\n\n\n\n

Featured accessories<\/h3>\n\n\n\n

For Schmidt-Cassegrain telescopes with C11 or C8 rear screws and focusers with 78 mm ring clamp, such as the Omegon Hybrid Crayford SC.<\/p>\n\n\n\n
