De flattener-functie strijkt tegelijk de veldkromming glad, zodat sterren ook in de hoeken van de sensor punten blijven.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De afstand tussen corrector en sensor bepaalt het resultaat. Houd de door TeleVue opgegeven werkafstand aan; elke millimeter afwijking is aan de hoeksterren te zien.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Before purchasing, check the focuser connection size and the required back focus of your camera; with a reducer, the distance to the sensor is critical. If you are unsure about the combination with your telescope, please contact us.<\/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 Bezitters van een NP101is of NP127is<\/li><li>\u2713 Wijdveldfotografie met een snelle refractor<\/li><li>\u2713 Wie de belichtingstijd bijna wil halveren<\/li><li>\u2717 Andere telescopen, de optische rekening klopt alleen voor de is-Petzvals<\/li><li>\u2717 Visueel gebruik<\/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>Type<\/strong><\/td><td>Focal reducer<\/td><\/tr><tr><td><strong>Factor<\/strong><\/td><td>0,8x<\/td><\/tr><tr><td><strong>Suitable for<\/strong><\/td><td>TeleVue NP101is en NP127is<\/td><\/tr><tr><td><strong>Camera side<\/strong><\/td><td>Grootformaat aansluiting voor de is-fotolijn<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">You can find the complete product line for this merk at the <a href=\"\/en\/brands\/televue\/\">TeleVue merk Page<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>NPR 0,8x reducer voor de fotografische TeleVue NP101is en NP127is refractors.<\/p>","protected":false},"featured_media":107715,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[1551],"product_cat":[56,469,3105,3104,3106],"product_tag":[],"class_list":["post-107713","product","type-product","status-publish","has-post-thumbnail","product_brand-televue","product_cat-telescoop-accessoires","product_cat-astro-fotografie","product_cat-optische-accessoires","product_cat-overige-astrofotografie-accessoires","product_cat-reducers","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":107669,"url":"https:\/\/www.telescoop.nl\/en\/televue-reducer-beeldveldegalisator-08x\/","url_meta":{"origin":107713,"position":0},"title":"TeleVue Reducer\/Field Flattener 0.8x TV-102 \u2013 Field Corrector","author":"Abdullah Ibrar","date":"29-04-2026","format":false,"excerpt":"Reducer\/flattener 0,8x specifiek voor de TeleVue TV-102 refractor.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"TeleVue Reducer\/beeldveldegalisator, 0,8x, voor 102 telescopen 0,8x reducer\/flattener met multicoating in zwarte behuizing op witte achtergrond","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Reducer-beeldveldegalisator-0-8x-voor-102-telescopen.jpg?resize=350%2C200&ssl=1","width":350,"height":200,"srcset":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Reducer-beeldveldegalisator-0-8x-voor-102-telescopen.jpg?resize=350%2C200&ssl=1 1x, https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Reducer-beeldveldegalisator-0-8x-voor-102-telescopen.jpg?resize=525%2C300&ssl=1 1.5x, https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Reducer-beeldveldegalisator-0-8x-voor-102-telescopen.jpg?resize=700%2C400&ssl=1 2x"},"classes":[]},{"id":26349,"url":"https:\/\/www.telescoop.nl\/en\/omegon-pro-reducer-08x-voor-94-517-triplet-ed-apo\/","url_meta":{"origin":107713,"position":1},"title":"Omegon Pro Reducer 0.8x for 94\/517 Triplet ED APO","author":"","date":"25-08-2025","format":false,"excerpt":"Modelgebonden reducer van 0,8x voor de Omegon Pro APO 94\/517 Triplet ED OTA.
