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° apparent field of view, this 25 mm 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 25 mm eyepiece excels for moderately low power scanning of open star clusters and viewing of extended nebulas and larger galaxies.

1. Fixed folding rubber eyecup allows easy use with or without eyewear

2. Svbony eyepiece body is made of aluminum. A two-step anodizing process results in a beautiful matte finish that resists reflections and glare

3. Sturdy anodized aluminum barrels are threaded for any Svbony 1.25" filters

4. The edges of the optics are blackened for increased contrast, and prevent internal reflections

5. Anti-reflection fully multi-coated optics ensure bright and clear high-images at any magnification, with true color rendition
