When you're out for a quick observation session or want to travel light, Lunt Solar System's 7.2-21.5mm Flat-Field Zoom Eyepiece gives you a wide choice of focal lengths in a single zoom design. A simple textured collar enables fast transition from a low-magnification focal length of 21.5mm to a high of 7.2mm. The flat-field design, seven lenses in four groups, removes the fuzziness and flared appearance that can often appear near the edges of conventional eyepieces to provide pin-sharp images across the entire 40-53° 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.
