With a wide 50-deg apparent field, our Sirius Plossl line of eyepieces provide clear, sharp images of impressively high contrast. They’re suitable all telescope types: reflector, refractor, and catadioptric. Each 4-element Sirius Plossl is multi-coated with magnesium fluoride for optimal light transmission and bright views. Lens edges are blackened to reduce scattering of stray light and maximize contrast. Lenses are mounted in black anodized aluminum housings with 1.25″ chrome-plated brass barrels. Each is fitted with rubber eyeguards and internally threaded to accept standard filters.
