An extension tube solves this by placing the accessory a fixed distance further from the telescope.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This version uses a ring clamp that secures the accessory all around instead of with a pointed screw. That prevents tilting, which in photography would be immediately visible as skewed stars. The internal grooves absorb stray light.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-2-verlengstuk-lengte-35mm.jpg\" alt=\"Omegon 2 inch extension tube with 35 mm optical length\" title=\"\"><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Telescope side and accessory side 2 inch<\/li><li>Optical length 35 mm<\/li><li>2-inch filter thread (M48)<\/li><li>Ring clamp for uniform clamping without tilting<\/li><li>Internal anti-reflection grooves against stray light<\/li><li>Aluminium, black, 100 g<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For telescopes and accessories with a 2-inch connection.
