Voor planeten, de maan en dubbelsterren laten orthoscopische oculairs daarom vaak n\u00e9t dat beetje meer detail zien dan complexere ontwerpen in dezelfde prijsklasse.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-3 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Oculair-Ortho-16-8-mm-1-25-3.jpg\" alt=\"Omegon Ortho 16,8 mm orthoscopisch oculair\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Oculair-Ortho-16-8-mm-1-25-2.jpg\" alt=\"Omegon Ortho 16,8 mm orthoscopisch oculair\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Oculair-Ortho-16-8-mm-1-25-1.jpg\" alt=\"Omegon Ortho 16,8 mm orthoscopisch oculair\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Oculair-Ortho-16-8-mm-1-25-.jpg\" alt=\"Omegon Ortho 16,8 mm orthoscopisch oculair\" title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Waarom orthoscopisch werkt<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Vier lenzen in twee groepen, elk oppervlak meerlaags gecoat: elke overgang die licht kan verstrooien is er een te veel, dus zijn er zo min mogelijk. Het beeld is rustig, contrastrijk en kleurzuiver, precies wat planeetwaarnemers zoeken.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De keerzijde is een bewust compact beeldveld. Wie panorama wil, kiest een groothoekserie; wie detail wil, zit hier goed.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Practical to use<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">De rubberen oogschelp houdt strooilicht buiten en de 1,25 inch vatting heeft filterschroefdraad voor maan- en kleurfilters.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Wat zie je met 16,8 mm?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Op een 130\/900 Newton geeft 16,8 mm een vergroting van 54x, op 1500 mm brandpuntsafstand 89x. De maanterminator met maximaal contrast, en planeten op een rustige middenvergroting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Op langzame telescopen zoals Maksutovs is dit een sterk vast planeetbrandpunt.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Combineer twee of drie Ortho-brandpunten voor een complete planeetset, of gebruik een Omegon Barlow lens om het bereik te verdubbelen. Een maanfilter draait direct in de filterschroefdraad.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">For whom yes and for whom no<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>\u2713 Planeet-, maan- en dubbelsterwaarnemers die scherpte boven beeldveld stellen<\/li><li>\u2713 Puristen die het maximale contrast uit hun telescoop willen halen<\/li><li>\u2717 Wie een ruim beeldveld of extra lange oogafstand zoekt: kies dan de LE Planeten- of Redline-serie<\/li><li>\u2717 Smart telescopes without interchangeable eyepieces<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Specifications<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Focal length<\/strong><\/td><td>16,8 mm<\/td><\/tr><tr><td><strong>Optical design<\/strong><\/td><td>orthoscopisch, 4 lenzen in 2 groepen, meerlaags gecoat<\/td><\/tr><tr><td><strong>Mount<\/strong><\/td><td>1.25 inch (31.7 mm), with filter thread<\/td><\/tr><tr><td><strong>Eyecup<\/strong><\/td><td>rubber<\/td><\/tr><tr><td><strong>Series<\/strong><\/td><td>Omegon Ortho<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">You can find more accessories for this merk at the <a href=\"\/en\/brands\/omegon\/\">Omegon merk Page<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Het Omegon Ortho 16,8 mm Oculair (1,25 inch) gebruikt een klassiek orthoscopisch ontwerp met vier lenzen voor maximale scherpte en contrast op planeten, de maan en dubbelsterren.<\/p>","protected":false},"featured_media":98827,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[126],"product_cat":[3130,3129,56],"product_tag":[],"class_list":["post-92430","product","type-product","status-publish","has-post-thumbnail","product_brand-omegon","product_cat-oculairen-standaard-gezichtsveld","product_cat-oculairs-en-barlows","product_cat-telescoop-accessoires","product_shipping_class-licht","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"bundled_by":[],"bundle_stock_status":"instock","bundle_stock_quantity":null,"bundle_virtual":false,"bundle_layout":"","bundle_add_to_cart_form_location":"","bundle_editable_in_cart":false,"bundle_sold_individually_context":"","bundle_item_grouping":"","bundle_min_size":"","bundle_max_size":"","bundle_price":[],"bundled_items":[],"bundle_sell_ids":[24771],"acf":[],"jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":92425,"url":"https:\/\/www.telescoop.nl\/en\/omegon-10-5mm-oculair-ortho-1-25-inch\/","url_meta":{"origin":92430,"position":0},"title":"Omegon Ortho 10.5 mm Eyepiece (1.25 inch)","author":"","date":"05-01-2026","format":false,"excerpt":"Het Omegon Ortho 10,5 mm Oculair (1,25 inch) gebruikt een klassiek orthoscopisch ontwerp met vier lenzen voor maximale scherpte en contrast op planeten, de maan en dubbelsterren.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Oculair-Ortho-10-5-mm-1-25-3.jpg?resize=350%2C200&ssl=1","width":350,"height":200},"classes":[]},{"id":92436,"url":"https:\/\/www.telescoop.nl\/en\/omegon-24mm-oculair-ortho-1-25-inch\/","url_meta":{"origin":92430,"position":1},"title":"Omegon Ortho 24mm Eyepiece (1.25 inch)","author":"","date":"05-01-2026","format":false,"excerpt":"Het Omegon Ortho 24 mm Oculair (1,25 inch) gebruikt een klassiek orthoscopisch ontwerp met vier lenzen voor maximale scherpte en contrast op planeten, de maan en dubbelsterren.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Oculair-Ortho-24-mm-1-25-3.jpg?resize=350%2C200&ssl=1","width":350,"height":200},"classes":[]},{"id":14031,"url":"https:\/\/www.telescoop.nl\/en\/baader-classic-ortho-oculairs-6-mm-10-mm-18-mm\/","url_meta":{"origin":92430,"position":2},"title":"Baader Classic Ortho Eyepieces 6 mm, 10 mm, and 18 mm","author":"","date":"10-04-2025","format":false,"excerpt":"Baader Classic Ortho 1.25-inch (31.75 mm) eyepieces are available in 6 mm, 10 mm, and 18 mm.
