Het langste brandpunt van de serie: lage vergroting, maximaal overzicht en de ruimste inkijk.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The series corrects the field curvature that makes most eyepieces blurry at the edge, and the ED lens element keeps the color reproduction pure. Even on fast Newtons around f\/5, the edge remains sharp.<\/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\/2025\/07\/Omegon-oculair-Premium-Flatfield-65d-25mm.jpg\" alt=\"Omegon Premium Flatfield 25 mm oculair met vlak beeldveld\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/07\/Omegon-oculair-Premium-Flatfield-65d-25mm-1.jpg\" alt=\"Omegon Premium Flatfield 25 mm oculair met vlak beeldveld\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/07\/Omegon-oculair-Premium-Flatfield-65d-25mm-2.jpg\" alt=\"Omegon Premium Flatfield 25 mm oculair met vlak beeldveld\" title=\"\"><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2025\/07\/Omegon-oculair-Premium-Flatfield-65d-25mm-3.jpg\" alt=\"Omegon Premium Flatfield 25 mm oculair met vlak beeldveld\" title=\"\"><\/figure><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Flat field, high contrast<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The optical construction with an ED element and multi-layer coating on all air-to-glass transitions delivers a sharp image with high contrast. Objects that drift to the edge retain their shape and sharpness.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Pleasant insight, parfocal series<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Met een oogafstand van 23 mm kijk je ontspannen, zonder zwarte schaduwen als je oog iets naast de as staat. De serie is parfocaal: wisselen van brandpunt vraagt nauwelijks bijscherpstellen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 1.25-inch barrel has filter threads for moon and color filters.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Wat zie je met 25 mm?<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Op een telescoop met 1200 mm brandpuntsafstand geeft 25 mm een vergroting van 48x, op 750 mm 30x. De Orionnevel en de Pleiaden staan er volledig in, met puntscherpe sterren tot aan de rand.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De oogafstand van 23 mm maakt dit het meest ontspannen oculair van de serie, ook met bril.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Featured accessories<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The Premium Flatfield series ranges from 5.5 to 25mm and is parfocal: two or three focal lengths form a complete set. An Omegon moon filter (1.25 inch) dims the bright moon image at longer focal lengths.<\/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 Observers with fast telescopes (f\/5) who value edge sharpness<\/li><li>\u2713 To see stars as pinpoints to the edge instead of smeared<\/li><li>\u2713 Owners of
