This provides a large field of view where open star clusters like the Pleiades and Hyades fit in one go, as well as distant landscapes during the day. With a total weight of approximately 4 kilograms, you can take it anywhere.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The achromatic doublet lens with multi-coating combines two types of glass to reduce chromatic aberration. At high magnification, a thin color fringe remains visible around bright objects; this is characteristic of this type of lens and does not interfere with normal use.<\/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\/2025\/02\/Omegon-telescoop-AC-80-400-AZ-3-1024x1024.jpg\" alt=\"Omegon AC 80\/400 AZ-3 wide-field refractor on tripod\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/02\/Omegon-telescoop-AC-80-400-AZ-3-1-1024x1024.jpg\" alt=\"Omegon AC 80\/400 AZ-3 complete with accessories\" 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\/2025\/02\/Omegon-telescoop-AC-80-400-AZ-3-2-1024x1024.jpg\" alt=\"The AZ-3 mount with fine adjustment from Omegon AC 80\/400\" 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\">AZ-3 with fine adjustment: quiet tracking<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The AZ-3 mount has fine-adjustment knobs on both axes. You perform coarse alignment by hand and then fine-tune it millimeter by millimeter. This makes tracking at higher magnifications smoother than with simple push-type mounts.<\/p>\n<\/div>\n<\/div>\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\/2025\/02\/Omegon-telescoop-AC-80-400-AZ-3-3-1024x1024.jpg\" alt=\"Omegon AC 80\/400 Red Dot Finder and Zenith Mirror\" 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\">20x and 40x: the field of view is the strength<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">With the included 20mm and 10mm eyepieces, you observe at 20x and 40x. This is deliberately a low-magnification telescope: at f\/5, an achromat shows significant chromatic aberration at high magnification. Star fields, the full moon disk, and terrestrial panoramas are its domain.<\/p>\n<\/div>\n<\/div>\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\/2025\/02\/Omegon-telescoop-AC-80-400-AZ-3-5-1024x1024.jpg\" alt=\"Omegon AC 80\/400 AZ-3 ready for nature observation\" 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\">Just as useful during the day as at night<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">With the 90-degree diagonal you can comfortably look up and over land. Birds on the dike, ships at sea, or a mountain ridge on vacation: the wide field of view makes searching easy.<\/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>AC-optics 80\/400 with multi-coating<\/li>\n\n\n<li>AZ-3 azimuthal mount with fine adjustment<\/li>\n\n\n<li>Adjustable height aluminum tripod<\/li>\n\n\n<li>20 mm and 10 mm eyepieces (1.25 inch)<\/li>\n\n\n<li>Red dot sight<\/li>\n\n\n<li>90 degree zenith mirror<\/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 7-21mm zoom eyepiece (69 euros) offers stepless magnification from 19x to 57x, precisely the strong range of this optic. An Omegon Premium moon filter (19.90 euros) dims the bright moonlight, and with the Omegon smartphone adapter 25-48mm (14.90 euros), you can photograph through the eyepiece.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Never look at the sun through a telescope without a certified solar filter: this can cause permanent eye damage within a second. For the partial solar eclipse on August 12, 2026, the Bresser solar eclipse glasses (\u20ac3.20) are the safest way to watch with the naked eye.<\/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 those looking for a lightweight, wide-field instrument for star fields, the Moon, and nature. Not for those who want to view planets at high magnification; for that, choose a longer focal length telescope, such as the 90\/1000 EQ-2 or a Maksutov.
