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-140-mm-Buisringen.jpg\" alt=\"Skywatcher 140 mm tube rings set of two white aluminum tube rings with felt lining and knurled screws 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.
