This yields significantly shorter exposure times, allowing you to capture more details and fainter deep-sky objects faster.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Designed specifically for the Omegon Pro APO 108\/600 Quintuplet, the reducer offers a fully corrected field of view that is also suitable for full-frame sensors. Thanks to the high-quality FMC coating, light transmission remains optimal and stars are sharp right to the edges of your shot.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On the telescope side, the reducer features an M80x1 and M90x1 internal thread, while the camera side offers an M48x0.75 external thread. With a back focus of 55 mm and an additional internal M48 filter thread, there is room for filters and adapters. In addition, the camera flange can be rotated using three bronze set screws, allowing you to precisely align the angle of view.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Observation goals<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The Omegon Reducer 0.7x for 108\/600 Quintuplet APO is ideal for astrophotography of vast deep-sky objects such as nebulae, galaxies and galaxy fields. Thanks to the reduction to f\/3.9, you benefit from shorter exposure times, less visible tracking errors and maximum utilization of full-frame sensors.<\/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>Reduction factor: 0.7x<\/li>\n\n\n\n<li>Suitable for: Omegon Pro APO 108\/600 Quintuplet OTA<\/li>\n\n\n\n<li>Focal length after reduction: 420 mm<\/li>\n\n\n\n<li>Aperture ratio: f\/3.9<\/li>\n\n\n\n<li>Optics Coating: Fully Multi-Coated<\/li>\n\n\n\n<li>Back focus: 55 mm<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Connections<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Telescope side: M68, M80x1 internal thread, M90x1 internal thread<\/li>\n\n\n\n<li>Camera side: M48x0.75 external thread<\/li>\n\n\n\n<li>Additional: M48 filter thread (internal), M78 external thread (lens holder)<\/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>Type: Flatteners, Correctors, Reducers<\/li>\n\n\n\n<li>Design: Reducer<\/li>\n\n\n\n<li>Weight: approx. 500 g<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p data-start=\"368\" data-end=\"729\">\u00a0<\/p>\n<p data-start=\"246\" data-end=\"366\"><strong data-start=\"246\" data-end=\"366\">Omegon Reducer 0.7x for 108\/600 Quintuplet APO comes with M68 telescope connector and M48 camera interface.<\/strong><\/p>","protected":false},"featured_media":26455,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[126],"product_cat":[469,587,3105,3104,3106,592,56],"product_tag":[],"class_list":["post-26452","product","type-product","status-publish","has-post-thumbnail","product_brand-omegon","product_cat-astro-fotografie","product_cat-camera-accessoires","product_cat-optische-accessoires","product_cat-overige-astrofotografie-accessoires","product_cat-reducers","product_cat-reducers-flatteners","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":[],"acf":[],"jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":107590,"url":"https:\/\/www.telescoop.nl\/en\/televue-oculairtas-transporttas\/","url_meta":{"origin":26452,"position":0},"title":"TeleVue Oculairtas \u2013 Carrying Case","author":"Abdullah Ibrar","date":"28-04-2026","format":false,"excerpt":"TeleVue Oculairtas \u2013 transporttas wordt geleverd met stevige foamvoering en biedt ruimte aan maximaal 13 oculairs en accessoires.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"TeleVue Transporttas Oculairtas gesloten grijze nylon oculairtas met handgrepen, ritssluiting en schouderriem op witte achtergrond","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Transporttas-Oculairtas-5.jpg?resize=350%2C200&ssl=1","width":350,"height":200,"srcset":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Transporttas-Oculairtas-5.jpg?resize=350%2C200&ssl=1 1x, https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Transporttas-Oculairtas-5.jpg?resize=525%2C300&ssl=1 1.5x, https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Transporttas-Oculairtas-5.jpg?resize=700%2C400&ssl=1 2x"},"classes":[]},{"id":105023,"url":"https:\/\/www.telescoop.nl\/en\/levenhuk-blitz-50-base\/","url_meta":{"origin":26452,"position":1},"title":"Levenhuk Blitz 50 BASE \u2013 50\/600 Refractor","author":"Abdullah Ibrar","date":"01-04-2026","format":false,"excerpt":"The Levenhuk Blitz 50 BASE \u2013 50\/600 Refractor comes with 6mm and 20mm eyepieces, a 3x Barlow lens, a 5x24 finder scope, a diagonal mirror, and an aluminum tripod.
