Sky-Watcher 102mm Toru rõngad

For 102mm & ED80 Skywatcher Refractor Telescope Tubes D=101mm (Without further modification this size is not compatible with the Skymax-90 Maksutov as that's about 103mm in diameter...) These quality cast aluminium rings are custom-made for use with either the AZ3, EQ1, EQ2, EQ3-2, EQ4, EQ5, HEQ5 and EQ6 (incl. PRO)  mounts/mounting plates.  Rings of the following internal diameters are available: 90mm, 102mm, 120mm, 130mm, 140mm, 150mm, 160mm, 182mm, 236mm & 285mm. They are felt-lined and hinged for easy installation of the telescope. By loosening the thumbscrews, the telescope can be easily balanced and rotated.
