Product Details

PENTAX XF eyepieces offer high-refraction, low-dispersion lanthanum glass elements to provide high-resolution images with minimal aberrations. PENTAX-original smc full-surface multi-layer coated optics reduce glare while providing maximum light transmission and color quality. Advanced computer simulation design technology was developed to reduce internal reflections, producing brighter, clearer images. Ideal for observation and photography of planets.

With JIS Class 4 weatherproof construction, the XF eyepieces are more durable and water resistant.

The PENTAX XF Zoom eyepiece provides magnification of 20 to 60 times with the PENTAX 65mm spotting scopes, an apparent field of view of 42 to 60 degrees, and an eye relief of 11mm to 15mm. Designed for use with PENTAX brand spotting scopes and with astronomical telescopes with appropriate 1 1/4" focuser.

The rotatable eyecup offers an adaptor-mounting screw/thread when removed (single-focus models: 30.5mm in diameter with a 0.5mm pitch; zoom: 43mm in diameter with a 0.75mm pitch).
