Extra-large field of view: High-quality, super wide-angle optics, combined with 42 mm lens diameter, ensure clear viewing, even at dusk;

Apochromatic optical system: Fluoride-containing ED lenses ensure exceptionally true-colour, high-luminosity and high-contrast image reproduction. At the same time, colour fringing at the edge of images is reduced to a minimum.Light transmission of over 90% thanks to fully multi-coated optics;

Flat Field Vision: High edge sharpness thanks to a smoothed image field；

High brilliance thanks to phase-corrected BaK-4 prisms featuring dielectric mirror coating；

Particularly hard-wearing thanks to an impact-resistant magnesium housing；

Water- and dirt-repellent objective and eyepiece coatings guarantee clear vision at ...
