The Svbony RedLine 68° Series Eyepieces offer an entry into the world of wide-angle eyepieces at an exceptionally low price.
With a 17 mm eye relief, they allow for comfortable observation even with glasses. The excellent contrast, image sharpness, and light transmission are ensured by fully-multicoated coatings and blackened lens edges. They fit into a 1.25" focuser, and standard filter threads along with a safety undercut are, of course, basic features.
