De Alpha Crayford is de goedkoopste manier om dat op te lossen zonder de rest van de telescoop te vervangen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Het Crayford-mechanisme werkt zonder tandheugel, zodat de beweging vloeiend verloopt en er geen speling in zit. Je vindt het scherpstelpunt sneller en houdt het vast.<\/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\/01\/Omegon-Alpha-Crayford-2-focuser-voor-Newton-telescopen-3.jpg\" alt=\"Omegon Alpha Crayford focuser 2 inch voor Newton-telescopen\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Alpha-Crayford-2-focuser-voor-Newton-telescopen-1.jpg\" alt=\"Omegon Alpha Crayford focuser 2 inch voor Newton-telescopen\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Alpha-Crayford-2-focuser-voor-Newton-telescopen-2.jpg\" alt=\"Omegon Alpha Crayford focuser 2 inch voor Newton-telescopen\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Alpha-Crayford-2-focuser-voor-Newton-telescopen.jpg\" alt=\"Omegon Alpha Crayford focuser 2 inch voor Newton-telescopen\" title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Ruime scherpstelweg van 59 mm<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Met 59 mm trekbuisweg heb je veel ruimte om oculairs met uiteenlopende bouwhoogte scherp te krijgen. Ook een barlow of een zenitspiegel past binnen het bereik zonder dat je verlengstukken nodig hebt.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Wrijving naar eigen hand zetten<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Met een stelschroef bepaal je hoe zwaar de focuser loopt. Een lichte instelling is prettig bij lichte oculairs, een zwaardere instelling voorkomt wegzakken bij een zwaardere accessoire.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De ringklem houdt het oculair rondom vast in plaats van met een enkele schroef. Dat scheelt kantelen en beschermt de huls van je oculair.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Waar deze focuser ophoudt<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Het draagvermogen ligt op 1 kg en er is geen fijnafstelling. Voor visueel werk is dat prima. Wil je met een spiegelreflex of astrocamera fotograferen, kijk dan naar een dual speed model.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Na montage van een nieuwe focuser moet je Newton opnieuw gecollimeerd worden. Een laser-collimator van 1,25 inch is daarvoor de snelste oplossing.<\/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 Beginners met een Newton die hun standaard focuser willen verbeteren<\/li><li>\u2713 Visuele waarnemers die soepeler willen scherpstellen<\/li><li>\u2713 Wie een grote scherpstelweg nodig heeft voor uiteenlopende oculairs<\/li><li>\u2717 Astrofotografie met een zware camera<\/li><li>\u2717 Wie fijnafstelling van 1:10 wil: kies dan een dual speed model<\/li><\/ul>\n\n\n\n<h3
