Pentax XW 14 Eyepiece 2 cm Black

The Pentax XW 14 eyepiece offers a 14 mm focal length with a 70° apparent field of view, delivering crisp, wide-field views for astronomical observation. Designed for 1.25 inch focusers, this eyepiece features a 7-element, 5-group optical design with SMC (Super Multi-Coating) for maximum light transmission and contrast. The twist-up rubber eyecup provides comfortable viewing, and the splashproof JIS Class 4 rating ensures durability in damp conditions. Built with high-refractive-index lanthanum glass, it corrects distortion and chromatic aberration for sharp, color-accurate images. The aluminum housing is lightweight yet robust, making it ideal for both refractor and reflector telescopes.
