This makes it the ideal tube for travel trackers like the Star Adventurer and for anyone looking for an ultra-light widefield system that can also keep up visually and for nature observation.<\/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\/2025\/07\/Omegon-Apochromatische-refractor-Pro-APO-AP-66-400-ED-OTA-5-1024x1024.jpg\" alt=\"Omegon 66\/400 Pro APO ED compact refractor\" 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\/07\/Omegon-Apochromatische-refractor-Pro-APO-AP-66-400-ED-OTA-6-1024x1024.jpg\" alt=\"Omegon 66\/400 Pro APO in transport case\" 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\/07\/Omegon-Apochromatische-refractor-Pro-APO-AP-66-400-ED-OTA-3-1024x1024.jpg\" alt=\"The 2-inch Crayford focuser of the Omegon 66\/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\">2 inch Crayford with rotation<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The 2-inch Crayford focuser features micro-focusing and rotates 360 degrees, allowing you to rotate the camera to any framing without releasing the clamp. With an optional flattener, the field is suitable for full-frame.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The f\/6 optics are versatile: wide enough for large nebulae, sharp enough for the Moon and double stars with an eyepiece in it.<\/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\/07\/Omegon-Apochromatische-refractor-Pro-APO-AP-66-400-ED-OTA-4-1024x1024.jpg\" alt=\"Omegon 66\/400 Pro APO with tube rings and dovetail\" 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\">Complete with case and clamps<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Two tube rings, dovetail and transport case are included: pack and go. During the day, with an amici prism, this is also an excellent spotting scope, and with a properly certified solar filter, a compact solar telescope. Never look or photograph toward the sun without a certified solar filter: that causes permanent eye injury and damage to your sensor within a second.<\/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>ED doublet 66\/400 with FPL-53 glass<\/li>\n\n\n<li>2-inch Crayford focuser with dual-speed adjustment and 360-degree rotation<\/li>\n\n\n<li>Two pipe clamps with dovetail<\/li>\n\n\n<li>Transport case<\/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 (39.90 euros) powers the tracker and camera on the go. For visual use, the Omegon 7-21 mm zoom eyepiece (69 euros) provides continuously variable magnification from 19x to 57x, and an Omegon Premium Moon filter (19.90 euros) dims the bright Moon.<\/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: traveling astrophotographers and anyone looking for a lightweight all-in-one system for the sky, nature, and the sun with a filter. Not for: those who want a larger aperture for smaller objects; the 80\/500 Pro APO Carbon is the logical step up. Are you hesitating between the models?
