Orion 25mm Sirius Plossl Eyepiece - 1.25"

Offering a wide 52° apparent field of view, this 1.25" Orion Sirius Plossl 25mm 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. It's no surprise that Orion Sirius Plossl eyepieces are best-sellers.

The Sirius Plossl 25mm eyepiece by Orion is fully coated with magnesium fluoride on every air-to-glass surface. 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 correctly position the eye on the eyepiece lens pupil.

This 25mm eyepiece excels for moderately low power scanning of open star clusters and viewing of extended nebulas and larger galaxies.

Limited Warranty against defects in materials or workmanship for one year from date of purchase.
