Introducing the WX series of ultra-wide-field binoculars, only Nikon could create it! This 10x model achieves an ultra-wide field of view (76.4° apparent field of view). Equipped with eyepieces that inherit the optical performance of the NAV-HW series astronomical telescope eyepieces, this model achieves an ultra-wide field of view (76.4° apparent field of view). Astigmatism and coma are minimized to ensure sharp central images even at the very edges of the ultra-wide field of view. Experience the sensation of floating among the stars, without the sense of boundaries of your field of view. Eyepiece with Advanced Optical Performance: This eyepiece inherits the optical performance of the NAV-HW series of astronomical telescope eyepieces, achieving an ultra-wide field of view (76.4° apparent field of view). By minimizing astigmatism and coma, the central image remains sharp all the way to the very periphery of the ultra-wide field of view. You'll feel as if you're swimming among the stars without even noticing the boundaries of your field of view. Field Flattener Lens System: The Field Flattener Lens System optimizes field curvature all the way to the very periphery of the field of view, ensuring a clear image even in the corners of the ultra-wide field of view. The wide field of view allows you to see star clusters and galaxies, and each star in the field of view appears as a single point image. Three ED (Extra-low Dispersion) Glass Elements in One Lens Tube: Three ED (Extra-low Dispersion) glass elements in one lens tube correct chromatic aberration, a cause of color bleeding, all the way to the very periphery of the field of view, achieving high contrast and resolution. High-Quality Multilayer Coating: All lenses and prisms are coated with high-quality multilayer coatings that provide uniform, high transmittance across the entire visible spectrum, achieving a more natural and bright field of view. Enjoy the true colors of the stars in the night sky. Abbe-König Prism: The highly transmittance Abbe-König prisms fully reflect all incident light on all reflective surfaces, resulting in a bright field of view. Furthermore, the roof surface is coated with a phase correction coating to correct phase shifts when light reflects within the prism, achieving high resolution and contrast. Optical design combines an ultra-wide field of view with long eye relief. Enjoy the ultra-wide field of view, from edge to edge, even while wearing glasses. All lenses and prisms are made of environmentally friendly, lead- and arsenic-free glass. The eyepiece features a turn-slide mechanism with six clicks for easy fine-tuning. The diopter adjustment ring features a diopter scale for convenient diopter adjustment. Waterproof, withstands immersion up to 5 meters in water for 10 minutes. The body is airtight, filled with nitrogen gas, preventing fogging and mold inside the optical system even when there are large temperature changes. The body is made of magnesium alloy, making it durable and lightweight enough to be carried around. A 55mm (P=0.75) filter can be attached. The TRA-4 tripod adapter for the WX series is included.
