Baader Genuine 12.5mm Orthoscopic Eyepiece 1.25"

Baader Genuine Orthoscopic eyepieces are particularly well suited for lunar, planetary and double star observers. This no compromise eyepiece has superb mechanical quality with proper Internal baffling and blackened lens edges for elimination of stray light reflections. The chrome plated barrels are threaded for standard 1¼" filters. On-axis sharpness is better than conventional Plossls and many wide field eyepieces. The classical orthoscopic eyepiece design has several advantages compared with Plossl eyepieces or wide angle design eyepieces. With less lens elements and only four glass to air surfaces and excellent light transmission and high contrast is the result.

You get a clear, undistorted image with this superb genuine orthoscopic design. Baader Genuine Orthoscopic Eyepieces have high quality multi-coatings which sets them apart from many other eyepiece designs. They have an excellent full multi-coating known as Phantom Multi Coating, i.e. a very effective anti-reflective multi-layer coating on each glass to air surface resulting in superior contrast and light transmission. The Orthoscopic design by Ernst Abbe for many has never been surpassed and remains the choice for serious planetary observers.
