Dit is een standaard reducer met ook veld afvlakkingsmogelijkheden. Een kortere brandpuntsafstand zorgt ervoor dat de OTA een breder gezichtsveld en snellere belichtingstijden heeft, waardoor hij geschikt is voor het vastleggen van grote gebieden met nevels, sterrenhopen en zwakke, snel bewegende hemellichamen.<\/p>\n<p>De 0.75x reducer heeft een tripletontwerp en ondersteunt een full-frame beeldcirkel van 44 mm. Het totale gewicht is 0.23 kg. De backfocus van de M48-schroefdraad is een standaard 55 mm. Beide uiteinden zijn M59 x 1. De 91F fotografische verlengbuis heeft twee maten M54 x 0,75 en M48 x 0,75 adapters, die direct en eenvoudig kunnen worden aangesloten op de 91F 0.75x reducer voor gebruik. Tegelijkertijd heeft de adapter een ingebouwde M48 x 0.75 2-inch filterdraad, die direct kan worden ge\u00efnstalleerd en gebruikt. De algehele CNC-gefreesde, aan beide uiteinden schroefdraad metalen doppen voorkomen stof wanneer niet in gebruik.<\/p>\n<p><a href=\"https:\/\/www.ganymedes.nl\/wp-content\/uploads\/2024\/10\/Askar-71F-reducer-2.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-47564 size-vp_sm\" src=\"https:\/\/www.ganymedes.nl\/wp-content\/uploads\/2024\/10\/Askar-71F-reducer-2-500x373.png\" alt=\"\" width=\"500\" height=\"373\" srcset=\"https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/10\/Askar-71F-reducer-2-500x373.png 500w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/10\/Askar-71F-reducer-2-324x241.png 324w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/10\/Askar-71F-reducer-2-416x310.png 416w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/10\/Askar-71F-reducer-2-300x224.png 300w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/10\/Askar-71F-reducer-2-768x572.png 768w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/10\/Askar-71F-reducer-2-140x104.png 140w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/10\/Askar-71F-reducer-2.png 800w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<h3>Specificaties van de\u00a00.75x Reducer zijn:<\/h3>\n<ul>\n<li>Brandpunt met montage reducer op 91F: 455 mm<\/li>\n<li>Brandpunt ratio na montage reducer: f\/5<\/li>\n<li>Triplet lens design<\/li>\n<li>Back Focus: 55 mm vanaf de M48 schroefdraad op de standaard adapter van de 91F telescoop.<\/li>\n<\/ul>\n<h3>Levering van de Askar 91F 0.75x Reducer:<\/h3>\n<ul>\n<li>Reducer 0.75x<\/li>\n<li>2 stofkappen<\/li>\n<\/ul>\n<h4>Plaats je bestelling online of kom langs in de winkel<\/h4>\n<p>Heb je gevonden wat je zoekt en wil je bijvoorbeeld de Askar 91F 0.75x reducer bestellen?
