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.
