Bresser Optics eyepiece PL 20mm 4920220

A proven quality Plössl eyepiece in a classic four-element design, ideal for expanding the eyepiece collection for smaller and medium telescopes. To ensure high light transmission (image brightness) and to avoid disturbing reflections, all lens surfaces are multi-coated. All Plössl eyepieces come with a rubber eyecup that provides additional comfort during observation and prevents stray light from entering from the sides. The eyepiece housing and barrel are made entirely of high-quality metal, not plastic. A standard 1.25-inch filter thread for color and nebula filters is, of course, included. To further reduce unwanted reflections, the inner sides of the eyepiece barrels are carefully blackened. The short focal lengths (high magnifications) are excellent for observing the Moon and planets, while the long focal lengths (low magnifications) allow for beautiful wide-field views of star clusters and nebulae with a comfortable eye relief. The Plössl eyepiece offers high contrast and optimal image sharpness.
