The fast f\/4.5 optics capture large swathes of the sky in short exposures: Milky Way fields, large nebula complexes, and bright comets.<\/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-DoubleED-AP-40-180-Quadruplet-OTA-3.jpg\" alt=\"Omegon Pro AP 40\/180 Sixtuplet Compact Astrograph\" 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-DoubleED-AP-40-180-Quadruplet-OTA-6.jpg\" alt=\"The helical focuser and rotation mechanism of the Omegon AP 40\/180\" 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\">Made for the travel tracker<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The helical focuser allows for fine, backlash-free focusing. The rotation mechanism turns your camera to the desired framing, and the M48 adapter connects directly to common camera adapters. The dew shield, Vixen-style dovetail, and tube rings are included.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to the integrated corrector, the image field is flat right away: no separate flattener, no fiddling with spacer rings.<\/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>Quadruplet-objective 40\/180 with two ED elements<\/li>\n\n\n<li>Integrated corrector (six elements total)<\/li>\n\n\n<li>Helical focuser with rotation mechanism<\/li>\n\n\n<li>M48 camera mount<\/li>\n\n\n<li>Dew shield<\/li>\n\n\n<li>Vixen-style dovetail and ring mounts<\/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 Powerbank 10k 12V (\u20ac39.90) keeps cameras and trackers powered all night, and the Omegon Pro UHC 2-inch filter (\u20ac89) brings out nebulae under a light sky.<\/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\">For astrophotographers traveling with a tracker and wanting maximum sky per gram: this is the lightest route to serious widefield shots. Not for those who also want to observe visually; this tube is built purely for the camera. For that, look at the AP 71\/490 with included eyepieces. Unsure between models?
