With this extension you bridge the optical path so that the focuser can be used in a normal position again and eyepieces or cameras focus without problems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The sleeve is made of black anodized aluminum and features internal slots that prevent reflections. Thanks to the sturdy spring ring clamp and lock nut, even heavy accessories remain stable and secure in place. At the bottom is an M48 filter thread for the use of 2\u2033 filters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A special detail of this model is the recess at the top. This is specially designed for the clamping screw of short 2\u2033\/1.25\u2033 reducers, making this extension sleeve a perfect fit for the Omegon Alpha Crayford 2\u2033 focuser for Newton telescopes.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Observation goals<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The Omegon 2\u2033 Extension Sleeve 45mm is ideal for correcting the focus point on telescopes optimized for photography. Thanks to the additional recess, this model is particularly suitable for Newton telescopes with a 2\u2033 Alpha Crayford focuser. Suitable for both visual observation and astrophotography.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Specifications<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Capacity<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Telescope connection: 2\u2033<\/li>\n\n\n\n<li>Camera side: 2\u2033<\/li>\n\n\n\n<li>Optical length: 45 mm<\/li>\n\n\n\n<li>Ring clamp: yes<\/li>\n\n\n\n<li>Filter thread: yes (M48x0.75)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>General<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Material: Aluminum<\/li>\n\n\n\n<li>Color: black<\/li>\n\n\n\n<li>Weight: 110 g<\/li>\n\n\n\n<li>Dimensions (LxWxH): 60 \u00d7 60 \u00d7 80 mm<\/li>\n\n\n\n<li>Type: Adapter<\/li>\n\n\n\n<li>Design: Extension<\/li>\n\n\n\n<li>Additional: internal anti-reflection slots, locking nut, special cutout for Crayford focuser<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p data-start=\"261\" data-end=\"570\">\u00a0<\/p>\n<p data-start=\"147\" data-end=\"259\"><strong data-start=\"147\" data-end=\"259\">Omegon 2\u2033 Extension sleeve 45 mm<\/strong><strong data-start=\"147\" data-end=\"259\">\u00a0Comes with spring ring clamp, lock nut and 2\u2033 filter thread.<\/strong><\/p>","protected":false},"featured_media":26716,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[126],"product_cat":[587,499,469,56],"product_tag":[],"class_list":["post-26711","product","type-product","status-publish","has-post-thumbnail","product_brand-omegon","product_cat-camera-accessoires","product_cat-adapters","product_cat-astro-fotografie","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":1,"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":26699,"url":"https:\/\/www.telescoop.nl\/en\/omegon-2-verlenghuls-50-mm\/","url_meta":{"origin":26711,"position":0},"title":"Omegon 2\u2033 Extension sleeve 50 mm","author":"","date":"26-08-2025","format":false,"excerpt":"\u00a0 The Omegon 2\" Extension Tube 50mm comes with a spring-loaded clamp, locking nut, and 2\" filter thread.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"Omegon 2\" Verlenghuls 50 mm","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-2-verlengstuk-lengte-50mm.jpg?resize=350%2C200&ssl=1","width":350,"height":200,"srcset":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-2-verlengstuk-lengte-50mm.jpg?resize=350%2C200&ssl=1 1x, https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-2-verlengstuk-lengte-50mm.jpg?resize=525%2C300&ssl=1 1.5x, https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-2-verlengstuk-lengte-50mm.jpg?resize=700%2C400&ssl=1 2x, https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-2-verlengstuk-lengte-50mm.jpg?resize=1050%2C600&ssl=1 3x, https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-2-verlengstuk-lengte-50mm.jpg?resize=1400%2C800&ssl=1 4x"},"classes":[]},{"id":93175,"url":"https:\/\/www.telescoop.nl\/en\/omegon-verlenghuls-voor-2-inch-crayford-focuser\/","url_meta":{"origin":26711,"position":1},"title":"Omegon Extension Sleeve For 2 Inch-Crayford Focuser","author":"Info telescoop","date":"09-01-2026","format":false,"excerpt":"Omegon extension sleeve comes with a 20 mm black aluminum extension piece fitted with M54 \u00d7 0.75 threads -
