Pentax XW-7 Eyepiece

The Pentax XW-7 Eyepiece is a premium 7mm wide-angle eyepiece designed for demanding astronomical and terrestrial observers who value image precision, comfort, and build quality. Engineered for use with both telescopes and compatible Pentax spotting scopes, this eyepiece delivers outstanding sharpness, contrast, and colour accuracy across the entire field of view.

Immersive Wide-Angle Viewing

Featuring a 70-degree apparent field of view, the Pentax XW-7 provides an immersive observing experience, making it ideal for detailed lunar, planetary, and deep-sky observation. This wide field allows objects to remain comfortably framed, especially useful when observing at higher magnifications or with manually tracked telescopes.

Exceptional Comfort & Eye Relief

The generous 20mm eye relief ensures comfortable viewing during extended observing sessions and makes the eyepiece well suited for eyeglass wearers without compromising image quality. The ergonomic design supports relaxed, fatigue-free observation even over long periods.

Advanced Optical Design

The optical system incorporates high-refraction lanthanum glass elements and fully multi-coated lenses to maximise light transmission while minimising chromatic aberration, internal reflections, and edge distortion. Advanced computer-optimised lens geometry further enhances clarity and contrast, delivering crisp, high-resolution views across the entire field.

Durable & Versatile Construction

Built for real-world use, the Pentax XW-7 eyepiece features weather-resistant construction that protects against moisture and environmental exposure, making it reliable for both night-time astronomy and daytime terrestrial viewing. Its 1.25-inch barrel ensures compatibility with a wide range of astronomical telescopes and standard filter accessories.

Combining optical excellence, long viewing comfort, and rugged build quality, the Pentax XW-7 Eyepiece is a high-performance choice for observers seeking consistent, professional-level results from their optical setup.
