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 43° apparent field of view, this 40mm Orion Sirius Plossl Telescope Eyepiece provides extremely sharp images of impressively high contrast. It’s 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 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 40mm telescope eyepiece yields the largest-possible field of view in a 1.25″ barrel. It’s superb for wide-field scanning and detailed observations of large diffuse subjects. Largest exit pupil and highest possible brightness.
