Pentax 70514 SMC-XW 10 1.25-Inch Telescope Eyepiece

The Pentax SMC-XW 10 is a high-performance 1.25-inch eyepiece built around extra-low-dispersion lanthanum glass elements and Pentax's proprietary multi-layer coatings. This optical combination delivers images that are bright, sharply resolved, and remarkably free of chromatic aberration and field distortion across the full 70° apparent field of view. Whether you are observing planetary detail, splitting tight double stars, or scanning deep-sky objects at moderate-to-high magnification, the XW 10 provides a view that rewards careful looking.

Beyond optics, the XW 10 addresses practical observing needs that matter during long sessions at the eyepiece. The 20mm eye relief is generous enough for comfortable use with eyeglasses, eliminating the need to squint or press your eye uncomfortably close. The JIS Class 4 weatherproof rating means dew, light rain, or humidity during evening observing will not compromise the eyepiece's internals. The rubber eyecup and solid build quality inspire confidence that this is a piece of equipment designed for years of regular use in real field conditions, not just ideal ones.
