Orion 08736 10mm Sirius Plossl Telescope Eyepiece (Black)
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 degree apparent field of view, this 10mm 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 inch-diameter chrome-plated brass barrel for durability and precision fit. The barrel is internally threaded to accept standard telescope filters. The built-in rubber eye guard enhances viewing by helping to block out ambient light and position the eye. This 10mm Orion Sirius Plossl Eyepiece is a great, moderately high power ocular for observing small planetary nebulas and globular star clusters, as well as for planetary probing when seeing conditions don't permit higher magnifications.
