The 20-60x variable eyepiece by Swarovski Optik provides bright, crystal clear images right up to the image periphery over a wide range of magnification. It is compatible with ATS, STS, and STR spotting scopes. The aspherical lens design reduces spherical aberration for sharp image detail especially at the edges.
The Swarotop multi-coating improves the light transmission to produce bright high-contrast images and the Swaroclean exterior lens coating repels water, oils, sap, and dirt to make views crisper and cleaning easier.
