The 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
