Plossl Eyepiece, 25MM Multi-Coated Astronomy Lens Eyepiece Plossl,
Offering a wide 52° apparent field of view, this 25 mm 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 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.
This 25 mm eyepiece excels for moderately low power scanning of open star clusters and viewing of extended nebulas and larger galaxies.
