You not only look up at the stars, but also over land and sea. One telescope, two worlds. That makes it versatile and fun to use.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>80 mm aperture, for clear and calm images<\/strong><br>The 80 mm lens captures enough light to show objects clearly. That means a quiet viewing experience with clear details. Ideal for wide star fields, open star clusters and bright objects such as the Moon.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/staging.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Telescoop-AC-80-400-OTA-1.jpg\" alt=\"Omegon Telescope AC 80\/400 OTA close-up of center section with Skywatcher mounting sticker\" class=\"wp-image-91870\" title=\"\"><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Short focal length, so an extra-large field of view<\/strong><br>Thanks to the short focal length of 400 mm, you can see a large chunk of the sky at once. Perfect for \u2018walking\u2019 along star fields. You see connections between objects and get oriented to the sky faster.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Rich-field telescope, made for exploring<\/strong><br>This telescope lets you enjoy overview rather than extreme magnification. Think of the Andromeda galaxy fitting nicely into view, or large open star clusters really coming into their own. Thus, observing feels relaxed and natural.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Also suitable for daytime nature observation<\/strong><br>Don't use your telescope only at night. During the day, you can just as easily look at landscapes, animals or ships in the distance. That makes this telescope ideal if you love being outdoors and want one instrument for everything.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/staging.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Telescoop-AC-80-400-OTA-2.jpg\" alt=\"Omegon Telescope AC 80\/400 OTA side view of aluminum tube with multicoated lens and focuser housing\" class=\"wp-image-91871\" title=\"\"><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Multicoating so your image stays clear<\/strong><br>The lenses have a multiple coating that reduces reflections. This keeps your image clear and rich in contrast. You see more details without distracting glare.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Light and sturdy, easy to assemble<\/strong><br>The aluminum tube is light but stable. Weighing only 1.3 kg, you can easily take it with you. You easily mount it on a suitable mount or tripod, just the way you want.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What we recommend<\/strong><br>\u2713 Widescreen observation: excellent fit<br>\u2713 Nature observation: very suitable<br>\u2713 Travel telescope: ideal<br>\u2717 Deep-sky details: not recommended<br>\u2717 Astrophotography: not suitable<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Specifications<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Optics<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Feature<\/th><th>Description<\/th><\/tr><\/thead><tbody><tr><td>Type<\/td><td>Refractor<\/td><\/tr><tr><td>Design<\/td><td>Achromat<\/td><\/tr><tr><td>Opening<\/td><td>80 mm<\/td><\/tr><tr><td>Focal length<\/td><td>400 mm<\/td><\/tr><tr><td>Opening ratio<\/td><td>f\/5<\/td><\/tr><tr><td>Resolution<\/td><td>1,44\u2033<\/td><\/tr><tr><td>Limit value<\/td><td>11.3 mag<\/td><\/tr><tr><td>Light output<\/td><td>130\u00d7<\/td><\/tr><tr><td>Maximum useful magnification<\/td><td>160\u00d7<\/td><\/tr><tr><td>Tube construction<\/td><td>Full tube<\/td><\/tr><tr><td>Dew pipe diameter<\/td><td>100 mm<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Focuser<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Feature<\/th><th>Description<\/th><\/tr><\/thead><tbody><tr><td>Design<\/td><td>Rack<\/td><\/tr><tr><td>Ocula Connection<\/td><td>1,25\u2033<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Mount<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Feature<\/th><th>Description<\/th><\/tr><\/thead><tbody><tr><td>Type of mount<\/td><td>Without mount<\/td><\/tr><tr><td>Design<\/td><td>OTA<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">General<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Feature<\/th><th>Description<\/th><\/tr><\/thead><tbody><tr><td>Series<\/td><td>Basic<\/td><\/tr><tr><td>Total weight<\/td><td>1.3 kg<\/td><\/tr><tr><td>Application<\/td><td>Moon &amp; planets, nature observation<\/td><\/tr><tr><td>Nebulae &amp; galaxies<\/td><td>Not recommended<\/td><\/tr><tr><td>Astrophotography<\/td><td>Not recommended<\/td><\/tr><tr><td>Sun<\/td><td>Not recommended (only with appropriate sunscreen)<\/td><\/tr><tr><td>Recommended for beginners<\/td><td>No<\/td><\/tr><tr><td>Suitable for advanced users<\/td><td>No<\/td><\/tr><tr><td>Observatory use<\/td><td>No<\/td><\/tr><\/tbody><\/table><\/figure>","protected":false},"excerpt":{"rendered":"<p><span style=\"--tw-border-spacing-x: 0;--tw-border-spacing-y: 0;--tw-translate-x: 0;--tw-translate-y: 0;--tw-rotate: 0;--tw-skew-x: 0;--tw-skew-y: 0;--tw-scale-x: 1;--tw-scale-y: 1;--tw-scroll-snap-strictness: proximity;--tw-ring-offset-width: 0px;--tw-ring-offset-color: #fff;--tw-ring-offset-shadow: 0 0 #0000;--tw-ring-shadow: 0 0 #0000;--tw-shadow: 0 0 #0000;--tw-shadow-colored: 0 0 #0000;border: 0px solid #e5e7eb;font-weight: 600;color: #34363d;font-family: Inter, 'Inter Fallback', ui-sans-serif, system-ui, sans-serif;font-size: 14px;background-color: #fdfdfe\">Omegon AC 80\/400\u00a0<\/span><span style=\"background-color: #fdfdfe;color: #34363d;font-family: Inter, 'Inter Fallback', ui-sans-serif, system-ui, sans-serif;font-size: 14px;font-weight: 600\">Telescope<\/span> <span style=\"--tw-border-spacing-x: 0;--tw-border-spacing-y: 0;--tw-translate-x: 0;--tw-translate-y: 0;--tw-rotate: 0;--tw-skew-x: 0;--tw-skew-y: 0;--tw-scale-x: 1;--tw-scale-y: 1;--tw-scroll-snap-strictness: proximity;--tw-ring-offset-width: 0px;--tw-ring-offset-color: #fff;--tw-ring-offset-shadow: 0 0 #0000;--tw-ring-shadow: 0 0 #0000;--tw-shadow: 0 0 #0000;--tw-shadow-colored: 0 0 #0000;border: 0px solid #e5e7eb;font-weight: 600;color: #34363d;font-family: Inter, 'Inter Fallback', ui-sans-serif, system-ui, sans-serif;font-size: 14px;background-color: #fdfdfe\">OTA<\/span><span style=\"color: #34363d;font-family: Inter, 'Inter Fallback', ui-sans-serif, system-ui, sans-serif;font-size: 14px;background-color: #fdfdfe\">\u00a0Comes with a compact aluminum refractor tube, rack and pinion focuser, multicoated optics and 1.25\u2033 connector -
