Description
The SVBONY SV190 Flat Field Eyepiece is sharp across the entire image and has an immediate level of view from edge to flat field of view. The correction priority of "distortion aberration" is low as the perimeter of objects that should be in a straight line and may cause "disappointment" for field scopes (spotting scopes) or binocular telescopes to observe terations. Field curvature is one of the defects in normal optical images. UF eyepiece correction allows you to use the entire field of view. FMC Coating Fully Multi-Coated Optics and 5-Element Lens Design FMC Film maximizes light transmission and minimizes internal reflections and maximizes contrast. FLAT VIEW UF series focuses on flatness and less distortion. Corrects distortion aberrations and provides a flat view to the peripheral area It will remain straight when you see the poles and others around the peripheral of your field of view. WIDE APPEARANCE VIEW The 65 degree ultra-wide angle eyepiece provides a wide view of the moon, planets, star clusters and more. 20mm eye relief foldable rubber eyecups and 20mm long eye relief provide a comfortable viewing experience with or without glasses. Black Lens Edge: The edges of the lens are black to reduce stray light scattering, and maximize contrast. Provides high image quality all the way around the field of view. Eye relief: 20mm 4.
