Deze uitvoering heeft M68-schroefdraad en past daarmee direct op de 2,5 inch Hexafoc focuser van Bresser-telescopen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without the correct distance, you simply cannot achieve focus: the focuser reaches the end of its travel before the image is sharp. This extension tube solves that. The aluminum is rigid and does not tilt, which is important for long focal length photography.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/Bresser-37-5mm-2-5-Verlengstuk-Hexafoc.jpg\" alt=\"Bresser verlengstuk 37,5 mm M68 voor Hexafoc\" title=\"\"><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Optische lengte van 37,5 mm (1,5 inch)<\/li><li>Rigid aluminum, no camera or eyepiece tilt<\/li><li>Resolves focus problems with eyepieces and cameras<\/li><li>Also usable as a spacer ring for the correct backfocus<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Voor de Bresser 2,5 inch Hexafoc focuser en andere M68-systemen.
