The Miyauchi 22x71 "Saturn II" NBA-71 has the longest focal length available in a production binocular. The long focal length (f/8) gives this model excellent color correction and edge-of-field sharpness, and allows much higher magnification than normally available in a binocular. With the optional 40x and 115x(!) eyepieces, it is excellent for planetary and lunar observation. Comes standard with 22x eyepieces, the Miyauchi 3x12 correct-image finderscope, and retractable glare shields. Can be mounted using the optional Miyauchi fork mount, or bottom-mounted to a tripod head or binocular mount (standard 1/40-20 and 3/8-16 threading). Optional hard-shell case now available.
