TS Optics 35mm 2” UFL okulaar

TS-Optics 35 mm Ultra-Flat-Field Eyepiece with 69° Field of ViewThe 2" ultra flat field eyepiece convinced with a very high standard of quality and a modern 6-element design. The optics is designed in a way that the field curvature is largely eliminated. The eyepiece is suited for all telescopes with a focal ratio of f/5 or slower. With faster telescopes the exit pupil would become too large, so light would be wasted. Further features of the TS UFL35: ♦ Special ED glasses for very good color correction♦ Adjustable metal eyecup with rubber ring as support for eyeglasses♦ Fully multi-coated with 99.98% transmission for maximum image brightness♦ Elaborate internal baffle system against stray light and reflections at the edge♦ Absolutely flat field without distorsion. The moon, for example, stays round even at the edge of the field and is not warped into an oval.♦ Smooth 2" barrel with conical upper part without safety notch - no tilting in focusers with compression ring
