Pentax

OPT is your source for Pentax Telescope Eyepieces. Designed with a high-refraction, low-dispersion lanthanum glass, these eyepieces consistently deliver bright, high-resolution images with minimal distortion. In addition to the XF series, the XW series eyepieces are built to JIS Class 4 weather-proof standards which increases their durability in less than ideal conditions.
