Voor maan- en planeetwaarneming is dit ontwerp na een halve eeuw nog altijd moeilijk te verbeteren.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Houd rekening met de korte oogafstand van ongeveer 6 mm, eigen aan elk Ploessl van deze brandpuntsafstand. Wie meer ruimte wil, combineert beter een 15 of 20 mm met een barlow.<\/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\/04\/TeleVue-Oculair-Ploessl-8mm-1-25-1.jpg\" alt=\"TeleVue Pl\u00f6ssl 8mm : 50\u00b0 1,25\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Oculair-Ploessl-8mm-1-25-.jpg\" alt=\"TeleVue Pl\u00f6ssl 8mm : 50\u00b0 1,25\" title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">The TeleVue Ploessl design<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Four lenses in two groups are all a good Ploessl needs. Because there are few glass surfaces, transmission remains high and contrast is maximized: precisely the characteristics that matter for planetary and lunar observation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">TeleVue T-type optics brought the design to the current level in the seventies, with tight manufacturing tolerances, multiple coatings, and blackened lens edges. You can see the difference compared to a standard supplied eyepiece right at the edge of the field.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Hoge vergroting of barlow-route<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Een 8 mm rechtstreeks in de focuser en een 15 mm met 2x barlow leveren bijna dezelfde vergroting. De barlow-route geeft de langere oogafstand van de 15 mm cadeau.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Voor wie zonder barlow wil werken blijft de 8 mm de directe weg naar planeetdetail, met het maximale contrast van vier glasoppervlakken.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">In your telescope<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">In een telescoop met 1200 mm brandpuntsafstand levert dit oculair ongeveer 150x met een waar beeldveld van circa 0,31 graden. Voor je eigen telescoop: waar beeldveld = 57,3 x veldstop gedeeld door de brandpuntsafstand van de telescoop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De effectieve veldstop van dit model is circa 6,5 mm.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A TeleVue 2x or 3x Barlow lens doubles or triples the magnification of any Ploessl eyepiece without any loss of quality; two Ploessl eyepieces plus a Barlow lens thus cover four magnification levels. Models 25 mm and larger also accept the Dioptrx astigmatism corrector.<\/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 Maan en planeten bij hoge vergroting<\/li><li>\u2713 Wie maximaal contrast per euro zoekt<\/li><li>\u2713 Aanvulling op een barlow-set<\/li><li>\u2717 Brildragers, de oogafstand is kort<\/li><li>\u2717 Wijdveldwaarnemingen<\/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>8 mm<\/td><\/tr><tr><td><strong>Apparent field of view<\/strong><\/td><td>50 degrees<\/td><\/tr><tr><td><strong>Effective field stop<\/strong><\/td><td>circa 6,5 mm<\/td><\/tr><tr><td><strong>Eye distance<\/strong><\/td><td>6 mm<\/td><\/tr><tr><td><strong>Stitch gauge<\/strong><\/td><td>1.25 inches<\/td><\/tr><tr><td><strong>Optical design<\/strong><\/td><td>Ploessl, 4 elements in 2 groups<\/td><\/tr><tr><td><strong>Filter thread<\/strong><\/td><td>Yes<\/td><\/tr><tr><td><strong>Coating<\/strong><\/td><td>Fully multi-coated, blackened lens edges<\/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>TeleVue Ploessl van 8 mm voor maan- en planeetwaarneming met hoog contrast.<\/p>","protected":false},"featured_media":107129,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[1551],"product_cat":[3129,3130,56],"product_tag":[],"class_list":["post-107127","product","type-product","status-publish","has-post-thumbnail","product_brand-televue","product_cat-oculairs-en-barlows","product_cat-oculairen-standaard-gezichtsveld","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":[107740],"acf":[],"jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":107137,"url":"https:\/\/www.telescoop.nl\/en\/televue-plossl-20mm-50-125-oculair\/","url_meta":{"origin":107127,"position":0},"title":"TeleVue Pl\u00f6ssl 20mm \u2013 50\u00b0 1.25\" Eyepiece","author":"Abdullah Ibrar","date":"17-04-2026","format":false,"excerpt":"TeleVue Ploessl van 20 mm als lage werkvergroting met hoog contrast.","rel":"","context":"Similar post","block_context":{"text":"Similar post","link":""},"img":{"alt_text":"TeleVue Pl\u00f6ssl-oculair, 20mm, 1,25\" close-up van het 1,25 inch Pl\u00f6ssl 20 mm oculair met geribbelde grip en groene Tele Vue opdruk","src":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Ploessl-oculair-20mm-1-25-1.jpg?resize=350%2C200&ssl=1","width":350,"height":200,"srcset":"https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Ploessl-oculair-20mm-1-25-1.jpg?resize=350%2C200&ssl=1 1x, https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Ploessl-oculair-20mm-1-25-1.jpg?resize=525%2C300&ssl=1 1.5x, https:\/\/i0.wp.com\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Ploessl-oculair-20mm-1-25-1.jpg?resize=700%2C400&ssl=1 2x"},"classes":[]},{"id":107133,"url":"https:\/\/www.telescoop.nl\/en\/televue-plossl-15mm-50-125-oculair\/","url_meta":{"origin":107127,"position":1},"title":"TeleVue Pl\u00f6ssl 15mm -
