This glass has extremely low chromatic aberration: stars remain truly white, nebulae retain their natural hues, and contrast remains high, from the center of the image to the edge.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An apochromat converges all colors to a focal point. Stars remain white and point-like, without the purple edges of simple lenses: precisely what a camera sensor would mercilessly reveal.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Apochromatische-refractor-Pro-APO-AP-85-510-Triplet-ED-FCD-100-1.jpg\" alt=\"Omegon Pro APO AP 85\/510 triplet with FCD-100 glass\" title=\"\"><\/figure>\n<\/figure>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8d39b2df wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:50%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Apochromatische-refractor-Pro-APO-AP-85-510-Triplet-ED-FCD-100.jpg\" alt=\"The 2.5-inch rack and pinion focuser of the Omegon AP 85\/510\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:50%\">\n<h4 class=\"wp-block-heading\">Triplet on a light mount<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">With an 85 mm aperture and 510 mm focal length (f\/6), this is a full-fledged deep-sky astrograph that can still fit on a mid-range mount. The 2.5-inch rack and pinion focuser with reduction supports a complete camera train without slipping.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Includes CNC tube rings, Vixen dovetail, finder adapter, and extendable dew shield: mount and get started.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Included<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Triplet objective 85\/510 with Hoya FCD-100 ED glass<\/li>\n\n\n<li>2.5 inch rack and pinion focuser with reduction<\/li>\n\n\n<li>CNC tube rings with Vixen dovetail<\/li>\n\n\n<li>Search adapter<\/li>\n\n\n<li>Extendable dew shield<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Featured accessories<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The Omegon Pro UHC 2-inch filter (\u20ac89) brings out emission nebulae under light-polluted skies. The Omegon Powerbank 10k 12V (\u20ac39.90) powers the mount and camera, and the Omegon Cronus 7mm eyepiece (\u20ac79) provides 73x magnification with high contrast.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">For whom yes, for whom no<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Good for: astrophotographers who want triplet quality without jumping to the top tier; this is the sharpest-priced 85mm triplet in the lineup. Not for: those who want the absolute maximum; the AP 85\/560 with OHARA FPL-53 glass and case is the premium version.
