7.5mm Orion Sirius Plossl Telescope Eyepiece

Ideal for reflector, refractor, and catadioptric telescopes and providing a wide 52-degree apparent field of view, the 7.5mm Orion Sirius Plossl Telescope Eyepiece’s four element design gives you extremely sharp images of impressively high contrast.

The optics for this Sirius Plossl Eyepiece are mounted in a black-anodized aluminum housing with a 1.25” diameter chrome-plated brass barrel that guarantees a precision fit. This eyepiece’s optical system is multi-coated for superb light transmission and bright views. The lens edges are blackened to reduce scattering of stray light which maximizes contrast. The built-in rubber eye guard helps block out ambient light and assists you in positioning your eye correctly.

Outstanding for high-power planetary and lunar observations, and even double-star viewing when stable viewing conditions permit, the 7.5mm Orion Sirius Plossl Eyepiece beats all competitors.
