The Svbony RedLine 68° Series 15 mm eyepiece is an affordable entry into the world of wide-angle eyepieces, offering particularly impressive views of deep-sky objects.
Its 17 mm eye relief ensures comfortable viewing, even for eyeglass wearers. Multilayered (fully multicoated) coatings and blackened lens edges provide excellent contrast, image sharpness and light transmission. It fits into a 1.25" focuser and naturally features a standard filter thread and a safety undercut.
