The Svbony RedLine 68° Series 20 mm eyepiece is an affordable entry into the world of wide-angle eyepieces, where deep-sky objects appear particularly impressive.
Its 17 mm eye relief allows comfortable observation, even while wearing glasses. Excellent contrast, image sharpness and light transmission are ensured by multilayered (fully-multicoated) coatings and blackened lens edges. It fits a 1.25" focuser and naturally features a standard filter thread and a safety undercut.
