Bij 110 graden houdt je oog het veld niet meer in een keer vast: je kijkt rond in het beeld in plaats van ernaar. Dat is het effect waar de Ethos-serie om bekendstaat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Practically, this also means that objects remain in view for longer. On a manually tracked Dobson, this saves constant readjustment.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8d39b2df wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:38%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Oculair-Ethos-4-7mm-1-25-2-.jpg\" alt=\"TeleVue Ethos 4,7mm 110\u00b0 : Oculair\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:62%\">\n<h4 class=\"wp-block-heading\">De praktische kant van 110 graden<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Het beeldveldoppervlak is ruim 20 procent groter dan bij de 100 graden Ethos-modellen. In de praktijk merk je dat vooral aan de rand: die valt buiten je directe blikveld, waardoor het gevoel van een rand grotendeels verdwijnt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De randcorrectie blijft ook in snelle systemen op orde. In een f\/4 Newton is een comacorrector alsnog aan te raden, omdat coma een eigenschap is van de spiegel en niet van het oculair.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8d39b2df wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:38%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Oculair-Ethos-4-7mm-1-25-2-1.jpg\" alt=\"TeleVue Ethos 4,7mm 110\u00b0 : Oculair\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:62%\">\n<h4 class=\"wp-block-heading\">Viewing Comfort and Dioptrx<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The eye relief is 15 mm at every focal length in the series. The height of the foldable eyecup is adjustable, so your eye is always in the same position.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you wear glasses due to astigmatism, you can replace them with Dioptrx on the eyepiece. This corrects your own cylindrical aberration without the eyeglass lenses costing contrast and eye distance.<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8d39b2df wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:38%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/04\/TeleVue-Oculair-Ethos-4-7mm-1-25-2-.jpg\" alt=\"TeleVue Ethos 4,7mm 110\u00b0 : Oculair\" title=\"\"><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:62%\">\n<h4 class=\"wp-block-heading\">In your telescope<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">In een telescoop met een brandpuntsafstand van 1200 mm levert dit oculair ongeveer 255x met een waar beeldveld van circa 0,43 graden. Je rekent dat voor je eigen telescoop uit met de veldstop: waar beeldveld = 57,3 x veldstop gedeeld door de brandpuntsafstand van de telescoop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De veldstop van dit model is 9,0 mm. Dat getal, en niet de brandpuntsafstand alleen, bepaalt hoeveel hemel je werkelijk ziet.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Included<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Foldable rubber eyecup<\/li><li>Eyecup protector<\/li><li>Dust cover for the stitch<\/li><li>Filter thread abandoned<\/li><li>Opschroefbare 2 inch adapter, die ook als standaard dient<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Every Ethos eyepiece is compatible with the TeleVue Dioptrx, a corrector for astigmatism that allows you to observe without glasses. If you\u2019re using a fast Newtonian, the Paracorr coma corrector will bring out that last bit of edge sharpness. For a 2-inch focuser, an Everbrite zenith mirror is the logical addition, and an eyepiece case protects your investment while on the go.<\/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 Planeetdetail bij middelhoge tot hoge vergroting<\/li><li>\u2713 Waarnemers die het maximale beeldveld willen bij korte brandpunten<\/li><li>\u2713 Gebruik in combinatie met een 3,7 mm of 6 mm Ethos<\/li><li>\u2717 Wie vooral deep-sky overzicht zoekt<\/li><li>Telescopes with a small aperture<\/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>4.7 mm<\/td><\/tr><tr><td><strong>Apparent field of view<\/strong><\/td><td>110 graden<\/td><\/tr><tr><td><strong>Effective field stop<\/strong><\/td><td>9,0 mm<\/td><\/tr><tr><td><strong>Eye distance<\/strong><\/td><td>15 mm<\/td><\/tr><tr><td><strong>Stitch gauge<\/strong><\/td><td>1,25 inch, met opschroefbare 2 inch adapter<\/td><\/tr><tr><td><strong>Filter thread<\/strong><\/td><td>Yes<\/td><\/tr><tr><td><strong>Dioptrx-compatible<\/strong><\/td><td>Yes<\/td><\/tr><tr><td><strong>Coating<\/strong><\/td><td>Fully multi-coated, blackened lens edges<\/td><\/tr><tr><td><strong>Eyecup<\/strong><\/td><td>Foldable, with protective cap<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">All wide-angle eyepieces are on the <a href=\"\/en\/telescope-accessories\/eyepieces-and-barlows\/wide-angle-eyepieces-wide-field\/\">page featuring wide-field eyepieces<\/a>.
