Een korte draai aan de sluitring en je oculair of diagonaal zit gelijkmatig rondom geklemd: kantelvrij, gecentreerd en krasvrij.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Het Rotolock-principe werkt als een twist-lock: geen losse klemschroeven, wisselen gaat met een handbeweging, ook met zware 2 inch oculairs en met handschoenen aan. Deze uitvoering is een van de drie kleurstellingen waarin William Optics deze visual back levert.<\/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\/2025\/11\/William-Optics-3.5-Rotator-Rotolock-Visual-Back-2.jpg\" alt=\"William Optics 3,5 inch Rotolock visual back\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/William-Optics-Rotator-Rotolock-Visual-Back-3-5.jpg\" alt=\"William Optics 3,5 inch Rotolock visual back\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/William-Optics-Rotator-Rotolock-Visual-Back-3-5-1.jpg\" alt=\"William Optics 3,5 inch Rotolock visual back\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/11\/William-Optics-Rotator-Rotolock-Visual-Back-3-5-2.jpg\" alt=\"William Optics 3,5 inch Rotolock visual back\" title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Voor de grote FLT-refractors<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Gemaakt voor de 3,5 inch focusers en verlengbuizen van de William Optics FluoroStar-lijn.
