- IDEAL FOR ASTRONOMICAL TELESCOPE: The XW40-R is the perfect eyepiece for viewing the nebula, planets and exploring the night sky.
- CLEAR, COMFORTABLE VIEWING: XW40-R eyepiece features an extra-wide 70? apparent angle of view and an extra-long 20mm eye relief to deliver an exciting image with a wide-perspective.
- HIGH-GRADE OPTICS FOR EXCEPTIONAL IMAGE QUALITY: The high-performance XW40-R's optics incorporates high-refraction, extra-low-dispersion lanthanum glass elements to produce a well-balanced image with minimal aberrations. It is particularly designed to reduce the disturbing blackout effect by effectively compensating for the spherical aberration of the pupil.
- SMC COATING: All lens surfaces that come in contact with air are treated with the original multi-layer coating, while all laminated surfaces are treated with the innovative partial coating, to offer the light transmission efficiency of more than 90 percent (an astonishing 96 percent at 550nm) over the visible light spectrum.
- ADVANCED LIGHT-SHIELDING TECHNOLOGY: Thanks to PENTAX?s advanced computer simulation technology, XW40-R features a light-shielding diaphragm at the most effective position to drastically reduce internal reflections for a brighter, higher-contrast image.
- ALL-WEATHER CONSTRUCTION: The XW40-R features JIS Class 4 weatherproof construction, making it possible to use it in drizzle or under night dew.
- BUILT-IN ADAPTER-MOUNTING SCREW: When the rotatable eyecup is removed, it also offers an adapter-mounting screw/thread (43mm in diameter with a 0. 75mm pitch).
