Lunt Solar System's four-element 8mm Flat-Field Eyepiece removes the fuzziness and flared appearance that can often appear near the edges of conventional eyepieces to provide pin-sharp images across the entire 53° apparent field of view. The optics are multicoated with proprietary 0.1% anti-reflective coatings that reduce ghosting and glow, and aid in providing a darker background. The eyepiece fits into 1.25" focusers and accessories.
