PENTAX XW series eyepieces are ideal for wide field observation.

With a 70-degree field of view, long (20mm) eye relief, and the superior, high-performance glass elements and optical performance PENTAX is known for, these eyepieces provide the ultimate in image sharpness and contrast.

All XW series eyepieces are constructed with a high-refraction, low-dispersion lanthanum glass that consistently delivers bright, high-resolution images with minimal distortion. In addition, all XW series eyepieces are built to JIS Class 4 weather-proof standards which increases their durability in less than ideal conditions. Designed for use with a wide range of telescopes and PENTAX brand spotting scopes, the XW series eyepieces are a clear choice for ground and astronomical applications.

The compact PENTAX XF series is ideal for planetary observations as well as general outdoor viewing. Each eyepiece provides a 60-degree field of view, 16mm eye relief and smc full-surface multi-layer lens coating for improved light transmission and high-refraction, low-dispersion glass elements for high-resolution images with minimal aberrations.

These eyepieces may also be used with PENTAX PF-65ED and 65ED-A spotting scopes.
