Ideaal als breedveldbuis op een bestaande opstelling, als richtkijker of als lichte reisbuis op een fotostatief.<\/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\/2026\/01\/Omegon-Telescoop-AC-80-400-OTA-1.jpg\" alt=\"Omegon AC 80\/400 OTA losse refractorbuis\" 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-Telescoop-AC-80-400-OTA-2.jpg\" alt=\"Tandheugelfocuser van de Omegon AC 80\/400 OTA\" 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\">Breed beeldveld, simpele bediening<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">De tandheugelfocuser met 1,25 inch aansluiting neemt elk standaardoculair. Met een 20 mm oculair kijk je op 20x en overzie je hele sterrenbeelden; sterrenvelden, de volledige maanschijf en overdag landschappen zijn het domein van deze buis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Houd de vergroting laag: bij f\/5 laat een achromaat boven ongeveer 80x een kleurrand zien. Dit is bewust een breedveldinstrument.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Zelf combineren<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Op een azimutale montering, een fotostatief met stevige kop of als tweede buis naast een grotere telescoop: deze OTA is het goedkoopste startpunt voor een eigen opstelling.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Included<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>AC-optiek 80\/400 met multicoating (losse buis)<\/li>\n\n\n<li>Tandheugelfocuser met 1,25 inch aansluiting<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Featured accessories<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">De Omegon Mini II Dobson-montering (59 euro) maakt er direct een complete tafelkijker van en het Omegon Titania 500 driepootstatief (129 euro) is de staande oplossing. Het Omegon 7-21 mm zoomoculair (69 euro) geeft traploos 19x tot 57x en een Omegon Premium maanfilter (19,90 euro) dempt de felle Maan.<\/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\">Wel: zelfbouwers en reizigers die een lichte breedveldbuis zoeken voor een bestaande montering of statief. Niet: wie een complete set uit een doos wil; de AC 80\/400 AZ-3 is dezelfde optiek met montering, statief en accessoires.
