Orion 6 mm Sirius Plossl 1.25" Eyepiece
Orion 6 mm Sirius Plossl 1.25" Eyepiece
The Plossl 4-element design is renowned for its outstanding performance. Offering a wide 52° apparent field of view, Orion Sirius Plossl telescope eyepieces provide clear, sharp images of impressively high contrast. They're ideal for all types of telescopes: reflector, refractor, and catadioptric such as Maksutov-Cassegrains and Schmidt-Cassegrains. The 6 mm focal length is ideal for both deep sky objects as well as planetary viewing.
The Sirius Plossl optical system is fully coated with magnesium fluoride on every air-to-glass surface. Lens edges are blackened to both reduce scattering of stray light and maximize contrast.
The lens edges are mounted in black-anodized aluminum housings with 1.25" diameter barrels for durability and precision fit in 1.25" telescope focusers, or 2" focusers equipped with a step-down 1.25" eyepiece adapter (not included). Each barrel is internally threaded to accept 1.25" Orion filters. The built-in rubber eyeguards enhance viewing by helping to block out ambient light and properly position the eye.
