The four-element design with multi-coating keeps the image bright, sharp, and true to color.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The included 2 to 1.25-inch adapter makes it usable with your entire eyepiece set, and the spring-ring clamp keeps everything scratch-free in place.<\/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\/2025\/08\/Omegon-Barlow-lens-2-5x-2-.jpg\" alt=\"Omegon 2.5x Barlow lens with 2-inch barrel\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Barlow-lens-2-5x-2-2.jpg\" alt=\"Omegon 2.5x Barlow lens with 2-inch barrel\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-Barlow-lens-2-5x-2-1.jpg\" alt=\"Omegon 2.5x Barlow lens with 2-inch barrel\" title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Why 2.5x?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The 2.5x factor sits right between the classic 2x and 3x: just a bit more reach than a standard Barlow, without intermediate focal lengths immediately exceeding usable magnification. With a 20mm and a 10mm eyepiece plus this Barlow, you cover four magnifications.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Also for photography<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The 2-inch filter thread accepts filters before the Barlow, and the sturdy clamp also carries a camera. For lunar and planetary photography, the 2.5 factor provides a significant increase in image scale.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Powerful in combination with 2-inch wide-angle eyepieces: the wide field of view is maintained while the magnification increases. Keep to a maximum of 2x the telescope aperture in millimeters.<\/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 Owners of 2 inch eyepieces who want just over a doubling<\/li><li>\u2713 Lunar and planetary photographers looking for image scale<\/li><li>\u2717 If you only have 1.25-inch eyepieces: choose a 1.25-inch Barlow<\/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>Magnification factor<\/strong><\/td><td>2,5x<\/td><\/tr><tr><td><strong>Optical design<\/strong><\/td><td>4 lens elements, multicoated<\/td><\/tr><tr><td><strong>Mount<\/strong><\/td><td>2 inch (50.8 mm), with filter thread and spring ring clamp<\/td><\/tr><tr><td><strong>Included<\/strong><\/td><td>2 to 1.25 inch adapter<\/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 2.5x Barlow Lens (2-inch), featuring four lens elements, delivers a sharp factor between 2x and 3x, and includes a 2 to 1.25-inch adapter and filter thread.<\/p>","protected":false},"featured_media":25746,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[126],"product_cat":[3134,3129,56],"product_tag":[],"class_list":["post-25735","product","type-product","status-publish","has-post-thumbnail","product_brand-omegon","product_cat-barlow-lenzen-en-focal-extenders","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":[],"acf":[],"jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":111636,"url":"https:\/\/www.telescoop.nl\/en\/zwo-seestar-s50-pro\/","url_meta":{"origin":25735,"position":0},"title":"ZWO Seestar S50 Pro","author":"Info telescoop","date":"25-08-2026","format":false,"excerpt":"The ZWO Seestar S50 Pro is the successor to the Seestar S50: 50 mm quadruplet APO (260 mm, f\/5.2), two 8.3 MP 4K sensors, a 63-degree wide-angle camera for the Milky Way up to 8K, three built-in filters, a 10,000 mAh battery (up to 9 hours), and 128 GB of storage.
