Nital has launched two extraordinary astronomical binoculars: the Nikon WX 7×50 IF and the Nikon WX 10×50 IF, the flagships of a century of optical excellence. Thanks to an unprecedented ultra-wide field of view, the WX series’ performance opens the doors to the starry sky and reveals details and color nuances never before observed.

Designed for the most demanding astronomy enthusiasts, these high-quality products use a lens system with a field flattener that compensates for curvature and ensures a stunningly sharp and crystal-clear view, from the center to the periphery. The Nikon multicoated coating and the high light transmission factor of Abbe-Koenig prisms, in turn, ensure exceptional brightness, guaranteeing optical performance of the highest caliber and an ultra-wide field of view, never seen before.

Each tube, equipped with three ED (Extra-low Dispersion) glass elements for a high-contrast, high-resolution image, accurately compensates for chromatic aberration, allowing you to visualize the subtle differences between the colors of all stars, right to the edge of the field of view. The high-quality multilayer coating is applied to all lenses and prisms, uniformly imparting high light transmittance across the entire visible spectrum, for a sharper and more natural view.

To ensure an excellent viewing experience for everyone, whether you wear glasses or not, the engineers who designed the Nikon WX series binoculars have managed to offer incredible eye relief along with an extremely wide field of view. The Nikon WX 7×50 IF binoculars have an apparent field of view of 66.6° and an eye relief of 17.7mm. The Nikon WX 10×50 IF binoculars have an apparent field of view of 76.4° and an eye relief of 15.3mm. Finally, the magnesium alloy ensures a solid yet lightweight body, while the multi-click eyecups make viewing comfortable, regardless of the duration of the astronomical observation session.

Main features of the binoculars

・The use of eyepieces with superior optical performance provides an ultra-wide field of view. The maximum containment of astigmatism and optical coma aberrations results in a sharp and clear image, while the sharpness of the image at the center of the field of view extends to the periphery of the field. Without perceiving the presence of the framing, you truly get the sensation of entering the scene and walking in space immersed in the starry sky..

・The field flattener lens system compensates for curvature from the center to the extreme edge of the periphery and generates an ultra-wide field of view, ensuring a sharp and clear image across the entire visual field, offering a panoramic view of galaxies or constellations; individual stars are then clearly visible as sharp points free of optical coma.

・Each tube is equipped with three ED (Extra-low Dispersion) glass elements, for a high-contrast, high-resolution image; this accurately compensates for chromatic aberration, allowing you to see the subtle differences between the colors of all stars up to the edge of the field of view.

・A high-quality multi-layer coating, characterized by uniformly high light transmittance across the entire visible spectrum, is applied to all lenses and prisms, to ensure a sharper and more natural view. It also faithfully reproduces the colors of the stars in the night sky.

・Abbe-Koenig prisms with Nikon multicoated coating on all surfaces are used because they ensure high light transmission.

・The application of a phase-correction coating on the roof (Dach) surfaces of the Abbe-Koenig prisms ensures high-resolution, high-contrast images at all times.

・Optical design that achieves an ultra-wide field of view and a comfortable eye relief. The exceptional width of the field of view is edge-to-edge, even for eyeglass wearers.

・Lead and arsenic-free glass is used for all lenses and prisms.

・Multi-click eyecups with six click stops make it easy to position your eyes at the correct eye relief.

・Waterproof construction that is not damaged if immersed in water up to a maximum depth of 5m for 10 minutes. (Based on Nikon tests. Not designed for underwater use.)

・Water-sealed construction with a pressure-filled nitrogen body that prevents the inside of the optical system from fogging up, as well as offering resistance to mold, even with significant temperature variations.

・Magnesium alloy is used to create a solid and durable body.

・55mm filter (P=0.75) can be attached to the objective lens.

・The two binoculars come with an exclusive tripod adapter (TRA-4) and a convenient, durable metal case.
