Description
Experience superior clarity with the Pentax SMC XF-8.5 eyepiece. Designed for both professionals and enthusiasts, this eyepiece uses high-refraction, low-dispersion lanthanum glass elements to deliver high-resolution images with minimal aberrations. Whether you are focused on deep-sky observation or high-detail photography of planets, this 8.5mm focal length tool provides the precision you need. To ensure maximum light transmission and color quality, Pentax utilizes original SMC full-surface multi-layer coated optics. This coating reduces glare and helps maintain vibrant colors in your view. Advanced computer simulation technology was used during the design process to reduce internal reflections, resulting in brighter and clearer images for your astronomical sessions. Built for reliability in various environments, the XF series features JIS Class 4 weatherproof construction. This makes the eyepiece more durable and water resistant, providing peace of mind during outdoor use. Trust in Pentax quality to enhance your optical performance and bring the wonders of the cosmos into sharper focus.
