Thanks to the flat field of view, objects remain sharp even at the edge of the image. This allows you to see planets and moon craters exactly as they are meant to be seen, without distortion. The ED lens element ensures a clean image with natural colors and high contrast, so that fine details stand out better.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>More overview with a large field of view<\/strong><br>With an apparent field of view of 60\u00b0, you are not looking through a narrow tunnel, but through a wide window on space. This gives a much calmer and more pleasant image than classic Pl\u00f6ssl eyepieces. You need less correction and can track objects more easily, especially at higher magnifications.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.telescoop.nl\/wp-content\/uploads\/2026\/01\/Omegon-Flatfield-ED-oculair-5mm-1-25-3.jpg\" alt=\"Omegon Flatfield ED eyepiece 5mm side view with chrome 1.25&quot; barrel and fixed eyepiece cap.\" class=\"wp-image-92464\" title=\"\"><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Comfortable viewing even at high magnification<\/strong><br>The view is relaxed and forgiving. Even if your eye is not perfectly centered, the image remains stable without disturbing shadows. The eye relief of 16 mm also makes this eyepiece suitable for eyeglass wearers.
