Description

Experience a wider perspective with the Pentax SMC XW-20 eyepiece. Designed to enhance your astronomical or terrestrial viewing, this eyepiece provides an improved 70 degree field of view. This wide field makes it easier to locate and track celestial objects or wildlife through your telescope or spotting scope. Built with high-quality optical components, the XW-20 uses high-refraction, low-dispersion lanthanum glass elements. These elements work together to deliver bright, high-resolution images while minimizing aberrations and distortions. The fully multi-coated lenses further improve your experience by increasing light transmission and enhancing color quality. Installation is straightforward thanks to the American-standard 31.7mm sleeve, which ensures a smooth fit with Pentax spotting scopes and various telescopes. For users requiring additional accessories, the rotatable eyecup can be removed to reveal a 43mm diameter adapter-mounting thread with a 0.75mm pitch. This eyepiece is a reliable choice for anyone seeking clear, high-quality visual performance.
