15000018: 25mm Orion Sirius Plossl Telescope Eyepiece

DESCRIPTION:


    This 1.25" 25mm focal length eyepiece is ideal for all types of telescopes: reflector, refractor, and catadioptrics including Maksutov-Cassegrains and      Schmidt-Cassegrains

    A great 25mm focal length eyepiece for moderate-power observations of the Moon and planets of the solar system

    The 25mm Sirius Plossl provides crisp views of many deep-sky objects such as nebulas and star clusters

    Multi-coated to provide bright views with impressively high contrast

    Offers a 52° apparent field of view for clear, sharp images of celestial and terrestrial fare


Offering a wide 52° apparent field of view, this 25mm 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 25mm eyepiece excels for moderately low power scanning of open star clusters and viewing of extended nebulas and larger galaxies.
