Nikon WX 10×50 IF Astronomy Binocular

Introducing Nikon WX. More than a lesson in optical achievement, WX speaks volumes towards catapulting its user into the frontier of incredible sharpness throughout a seemingly endless viewing periphery. Not only will this super-wide field of view seemingly transport an entire constellation of crystal-clear imagery to the eyes of the beholder, but do so with the amazing realism that has become Nikons hallmark for 100 years.

Nikon WX is truly the Binocular of the Century.

Advanced level of sturdiness and operability: Magnesium alloy is utilized, realizing a sturdy, lightweight body that facilitates handheld viewing. Employing Abbe-Koenig prisms enables a slim design that carefully pays attention to weight balance.

Thread for attaching filter: 55mm filter (P=0.75) can be attached to objective lens.

Accessories that support comfortable astronomical observation: Comes with an exclusive tripod adapter TRA-4. 1/4-in. (ISO1222) tripod screw enables attaching to a tripod. WX binoculars exclusive case is supplied for storing the binoculars and accessories.

Straight helicoid diopter adjustment ring: The diopter adjustment ring employs a straight helicoid design. Eyepieces move back and forth in a straight line, and the lenses themselves do not rotate, ensuring the optical axis is not decentered during diopter adjustment.

Turn-and-slide rubber eyecups with six-click adjustment facilitate easy positioning: Click intervals become finer as the eyecups are extended, for easier adjustment by non-eyeglass users.

Long eye relief: Optical design that realizes both a super-wide field of view and long eye relief. Eyeglass wearers can also enjoy a full, clear super-wide field of view. Rubber eyecups are designed to be removed for cleaning eyepieces. Eyepiece frame is designed in a flat shape for easy maintenance of details.

All lenses and prisms are free of lead and arsenic: Under the Nikon Green Procurement Standards, we employ not only lenses and prisms but also body materials taking the environment into special consideration.

Waterproof and fogproof structure that withstands severe conditions: Waterproof structure that will not be affected if submerged in water to a maximum depth of 5m/16.4 ft. for 10 minutes. (NOT designed for underwater usage.) Airtight structure with a nitrogen-filled body that prevents the inside of the optical system from fogging and resists mold even with significant changes in temperature. Wide operating temperature range of -20C to +60C/-4F to +140F enables use in severe conditions.
