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\">De laagste vergroting die 2 inch toelaat<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Op een Schmidt-Cassegrain van f\/10 levert de 55 mm een uittredepupil van 5,5 mm en het grootst mogelijke veld: precies waarvoor dit oculair is bedoeld. Op een snelle Newton wordt diezelfde pupil groter dan het oog benut en gaat er licht verloren.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De in hoogte verstelbare oogschelp helpt om het oog op de royale afstand van de ooglens stabiel te positioneren.<\/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 22x met een waar beeldveld van circa 2,20 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 46,0 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 Langzame telescopen vanaf ongeveer f\/7<\/li><li>\u2713 Het maximale veld tegen de laagste prijs<\/li><li>\u2713 Brildragers, met de langste oogafstand van de serie<\/li><li>\u2717 Snelle telescopen,
