About the Orion 7.5mm

The Orion 7.5mm & 12.5mm Sirius Plossl Eyepiece has a wide 52° apparent field of view (43° for the 40mm) which provides extremely sharp images of impressively high contrast. They're ideal 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 eyepieces are judged.

The Sirius Plossl optical system is fully coated with magnesium fluoride on every air-to-glass surface. Lens edges are blackened to reduce scattering of stray light and maximize contrast. The lenses are mounted in black-anodized aluminum housings with 1.25"-diameter chrome-plated brass barrels for durability and precision fit. Each barrel is internally threaded to accept standard filters.

The built-in rubber eyeguards enhance viewing by helping to block out ambient light and position the eye. The 7.5mm is superb for high-power planetary and lunar observation and well suited to double-star viewing when stable seeing conditions permit. The 12.5mm, a useful intermediate focal length, performs well on both deep-sky and planetary subjects.
