The rings open completely, allowing you to place the telescope directly in rather than sliding it in from the front. The felt lining on the inside protects the finish while still holding the tube firmly in place.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/12\/Skywatcher-Buisringen-90mm.jpg\" alt=\"Skywatcher Tube Rings 90mm set of two black aluminum tube rings with knurled screws and camera mounting thread on white background.\" title=\"\"><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Loosen the thumbscrews a turn and you can slide or rotate the tube freely: exactly what you need for balancing after changing eyepieces or cameras, or to position the focuser in a comfortable position. The thread on top also allows you to piggyback a camera or a second accessory.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>Set of 2 foldable aluminum rings with quick release<\/li>\n\n\n<li>Felt lining: firm grip without scratches<\/li>\n\n\n<li>Free rotation and sliding for balance and focus mode<\/li>\n\n\n<li>Camera mount screw thread for piggyback use<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Inner diameter 90 mm, suitable for optical tubes with that diameter: small refractors, for example in the 72 to 80 mm class. If in doubt, measure the outer diameter of your tube. Mount the rings on a Vixen or Losmandy dovetail of your choice.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Type<\/strong><\/td><td>Bushings (set of 2)<\/td><\/tr><tr><td><strong>Inside diameter<\/strong><\/td><td>90 mm<\/td><\/tr><tr><td><strong>Material<\/strong><\/td><td>Aluminum, felt lining<\/td><\/tr><tr><td><strong>Quick release<\/strong><\/td><td>Yes<\/td><\/tr><tr><td><strong>Camera screw thread<\/strong><\/td><td>Yes<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The disassembly of <a href=\"https:\/\/www.telescoop.nl\/en\/brands\/sky-watcher\/\">Sky-Watcher<\/a> is a base that will last you for years.
