TeleVue durft de vergelijking aan met welk oculair dan ook zonder barlow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Voor wie een set opbouwt is dit de goedkoopste manier om het aantal vergrotingen te verdubbelen zonder aan beeldkwaliteit in te leveren.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-3 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Barlowlens-1-25-2x.jpg\" alt=\"TeleVue 2x 1.25\" : title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Wat een goede barlow doet<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Een barlow verlengt de effectieve brandpuntsafstand van je telescoop en verhoogt zo de vergroting van elk oculair dat erin steekt. Twee oculairs plus een barlow dekken daarmee vier vergrotingen af.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De kwaliteit van het glas bepaalt of je dat gratis krijgt of ervoor betaalt met contrast. TeleVue gebruikt hoogbrekend glas met meervoudige coatings; het verschil met het oculair alleen is in de praktijk niet te zien.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Effect op de oogafstand<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Een klassieke barlow vergroot de oogafstand van korte oculairs iets. Bij een Ploessl is dat welkom: een 15 mm met barlow kijkt ruimer weg dan een losse 7,5 mm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Wil je een vergrotingsfactor zonder enig effect op oogafstand of uittredepupil, dan is de telecentrische Powermate het alternatief binnen het merk.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Combineer de barlow met de TeleVue Ploessls voor een compacte set die vier vergrotingen dekt. De oculairs zijn parfocaal, dus wisselen kost nauwelijks scherpstelwerk.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">For whom yes and for whom no<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>\u2713 Wie met twee oculairs vier vergrotingen wil<\/li><li>\u2713 Planeetwaarnemers<\/li><li>\u2713 Bezitters van TeleVue Ploessls of DeLites<\/li><li>\u2717 Fotografen die een constante factor op afstand nodig hebben, zie de Powermate<\/li><li>\u2717 2 inch oculairs<\/li><\/ul>\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>Magnification factor<\/strong><\/td><td>2x<\/td><\/tr><tr><td><strong>Stitch gauge<\/strong><\/td><td>1.25 inches<\/td><\/tr><tr><td><strong>Coating<\/strong><\/td><td>Fully multi-coated<\/td><\/tr><tr><td><strong>Filter thread<\/strong><\/td><td>Yes<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">More eyepieces and Barlows are on the <a href=\"\/en\/telescope-accessories\/eyepieces-and-barlows\/\">Accessory page for eyepieces and Barlows<\/a>.
