Deze uitvoering heeft aan beide zijden een 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\">Zonder de juiste afstand bereik je simpelweg geen focus: de focuser komt aan het eind van zijn slag voordat het beeld scherp is. Dit verlengstuk lost dat op. Het aluminium is stijf en kantelt niet, belangrijk bij fotografie met lange brandpuntsafstanden.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/10\/Bresser-Verlengstuk-25mm-2-5-Hexafoc.jpg\" alt=\"Bresser verlengstuk 25 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 25 mm (1 inch)<\/li><li>Stijf aluminium, geen kanteling van camera of oculair<\/li><li>Lost focusproblemen op bij oculairs en camera's<\/li><li>Ook bruikbaar als afstandsring voor de juiste 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.
