• 【52° Wide Apparent Field of View】 The telescope eyepiece with a wider 52° apparent field magnifies the angle and provides a broader perspective for lunar observations, medium sized star clusters, and a wide range of cloudy nebulas and deep sky targets 【Fully Mutiple Coated HD Optical Glass】 Two sets of four slices of fully multi coated HD optical glass reduces the chromatic aberration and increase lens permeability to get bright and clear views with impressively high contrast. The included dust covers keep the lenses free from dust or damage 【Foldable Rubber Eye Care】 The foldable rubber eyecup blocks out stray light and provides a soft rubber cushioned surface for comfortable and stable viewing during extended sessions. The 17mm proper exit pupil distance allows for extended eye relief 【Fine Tuned Focal Length】 With a fixed focal length of 38mm, the eyepiece still offers a rotatable lens barrel to fine tune for glasses wearers, who can rotate to find the most comfortable distance without removing their glasses 【1.25" Standard Interface】 Comes with a standard 1.25" interface to connect any telescopes that support 1.25" eyepieces. To securely attach to the zenith mirror or other devices, simply insert it into the eyepiece hole and tighten the knob to complete the installation
