New Pentax eyepieces: SMC PENTAX XW Eyepieces 16.5mm and 23mm

New Pentax eyepieces: SMC PENTAX XW Eyepieces 16.5mm and 23mm

These eyepieces expand the XW series to ten eyepieces and complete the range of functional, practical focal lengths for a wide range of applications, from low magnification stargazing to high magnification planetary observation.

Main features of the smc PENTAX XW eyepieces 16.5mm and 23mm

• Extra large field of view: The XW 16.5mm and 23mm have the largest fields of view in the series at 85°.
• High-quality optics for exceptional image quality: The eyepiece features a new optical system with 7 elements in 5 groups that outperforms the conventional XW series to provide sharp constellations right to the edge of the field of view
• PENTAX original multi-coating for outstanding light transmission: light transmission reaches more than 90 percent (an amazing 96 percent at 550nm) across the visible light spectrum.
• Advanced light-shielding technology for improved image contrast:
• Thanks to PENTAX's advanced computer simulation technology, the XW series features a light-shielding aperture at the most effective position to dramatically reduce internal reflections and provide a brighter, higher contrast image.
• Weatherproof construction for all-weather observing: the XW series features JIS Class 4* weatherproof construction, enabling use even in drizzle or nighttime dew.
