Designed to work with their ATS, STS, and STR spotting scopes, the Swarovski Optik 20-60x Zoom Spotting Scope Eyepiece maintains the wide magnification range and long eye relief, regardless of the spotter it is installed on. Its aspherical lens design virtually eliminates spherical aberration to produce crisp and sharp views - especially at the edges. Engineered to work seamlessly with the spotting scope optics, the eyepiece sports the proprietary SWAROTOP and SWAROCLEAN lens coatings to improve light transmission for brighter images, and to increase contrast; while repelling water, oils, dirt, and sap to make views clearer and cleaning easier. At lower magnifications the apparent angle of view reaches a wide 65°, and its ridged zoom collar makes it easy to progress through the entire magnification range quickly to make detailed observations at the higher powers.
