Orion 20mm Sirius Plossl Eyepiece – 1.25″

The eyepieces in Orion’s Sirius Plossl line are their best-selling telescope eyepieces. They are of exceptional quality and within a reasonable price range!

Offering a wide 52° apparent field of view, this 20 mm Orion Sirius Plossl Telescope Eyepiece provides super sharp images of impressively high contrast. It’s perfect for all types of telescopes: reflector, refractor, and catadioptric. The Plossl 4-element design is renowned for its outstanding performance, and has become the standard by which all other telescope eyepieces are judged and manufactured.

The Sirius Plossl optical system is multi-coated for excellent light transmission and bright views. Lens edges are blackened to reduce scattering of stray light and maximize contrast.

The lenses are mounted in black-anodized aluminum housings with a 1.25″-diameter chrome-plated brass barrel for durability and precision fit. The barrel is internally threaded to accept standard telescope filters. The built-in rubber eyeguard enhances viewing by helping to block out ambient light and position the eye.

This 20mm Orion Sirius Plossl Telescope Eyepiece is wonderful for moderately low power scanning of open star clusters and viewing of extended nebulas and larger galaxies.
