For planets, the moon, and double stars, orthoscopic eyepieces therefore often reveal just that little bit more detail than more complex designs in the same price range.<\/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-24-mm-1-25-3.jpg\" alt=\"Omegon Ortho 24 mm orthoscopic eyepiece\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Oculair-Ortho-24-mm-1-25-2.jpg\" alt=\"Omegon Ortho 24 mm orthoscopic eyepiece\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Oculair-Ortho-24-mm-1-25-1.jpg\" alt=\"Omegon Ortho 24 mm orthoscopic eyepiece\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Oculair-Ortho-24-mm-1-25-.jpg\" alt=\"Omegon Ortho 24 mm orthoscopic eyepiece\" title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Why orthoscopic surgery works<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Four lenses in two groups, each surface multi-layered coated: every transition that can scatter light is one too many, so there are as few as possible. The image is calm, rich in contrast and colour purity, exactly what planet observers are looking for.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The downside is a deliberately compact field of view. Those who want a panorama choose a wide-angle series; those who want detail are well catered for here.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Practical to use<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The rubber eye shell keeps stray light out, and the 1.25-inch aperture has filter thread for moon and color filters.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">What do you see with 24 mm?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">On a telescope with a 1200 mm focal length, 24 mm gives a magnification of 50x. The entire moon disc in one richly contrasting image, and a convenient focal point of focus for clear objects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even for entry-level orthopaedic examinations, the 24 mm is the most accessible choice.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Combine two or three Ortho focal points for a complete planetary set, or use an Omegon Barlow lens to double the range. A moon filter screws directly into the filter thread.<\/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 Planet, moon and double star observers who achieve sharpness above the field of view<\/li><li>\u2713 Purists who want to get the maximum contrast out of their telescope<\/li><li>\u2717 If you are looking for a wide field of view or extra long eye distance: choose the LE Planeten or Redline series<\/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>24 mm<\/td><\/tr><tr><td><strong>Optical design<\/strong><\/td><td>orthoscopic, 4 lenses in 2 groups, multilayer coated<\/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 brand at the <a href=\"\/en\/brands\/omegon\/\">Omegon brand page<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>The Omegon Ortho 24 mm eyepiece (1.25 inch) uses a classic orthoscopic design with four lenses for maximum sharpness and contrast on planets, the Moon and double stars.<\/p>","protected":false},"featured_media":98831,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[126],"product_cat":[3130,3129,56],"product_tag":[],"class_list":["post-92436","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","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":92430,"url":"https:\/\/www.telescoop.nl\/en\/omegon-16-8mm-oculair-ortho-1-25-inch\/","url_meta":{"origin":92436,"position":0},"title":"Omegon Ortho 16.8mm Eyepiece (1.25 inch)","author":"","date":"05-01-2026","format":false,"excerpt":"The Omegon Ortho 16.8 mm eyepiece (1.25 inch) uses a classic orthoscopic design with four lenses for maximum sharpness and contrast on planets, the moon, and double stars.","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-16-8-mm-1-25-3.jpg?resize=350%2C200&ssl=1","width":350,"height":200},"classes":[]},{"id":92425,"url":"https:\/\/www.telescoop.nl\/en\/omegon-10-5mm-oculair-ortho-1-25-inch\/","url_meta":{"origin":92436,"position":1},"title":"Omegon Ortho 10.5 mm Eyepiece (1.25 inch)","author":"","date":"05-01-2026","format":false,"excerpt":"The Omegon Ortho 10.5 mm eyepiece (1.25 inch) uses a classic orthoscopic design with four lenses for maximum sharpness and contrast on planets, the moon, and double stars.","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":14031,"url":"https:\/\/www.telescoop.nl\/en\/baader-classic-ortho-oculairs-6-mm-10-mm-18-mm\/","url_meta":{"origin":92436,"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.
