Product Description

It's no surprise that the eyepieces in our Sirius Plossl line are our best-selling telescope eyepieces. Quality this good usually costs a lot more.

Offering a wide 52° apparent field of view, these 7.5mm, 12.5mm, and 20mm Orion Sirius Plossl Telescope Eyepieces provide extremely sharp images of impressively high contrast. They are 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 telescope eyepieces are judged.

The Sirius Plossl optical system is multi-coated for excellent light transmission. 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 Sirius Plossl Expansion Set includes three eyepieces: our 7.5mm, 12.5mm, and 20mm models.

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.

For moderately low power scanning of open star clusters, and viewing of extended nebulas and larger galaxies, the 20mm model excels.
