About Product

Employing eyepieces with superior optical performance, a super-wide field of view (apparent field of view of 66.6° for WX 7x50 IF, 76.4° for WX 10x50 IF) is achieved.
Minimising astigmatism and coma aberration, a sharp and clear image is realised, while the sharpness of the image at the centre of the field is achieved all the way to the periphery of the super-wide field of view. Without perceiving the frame, you can experience a feeling as if you are spacewalking into a starry sky.
The Field Flattener Lens System is employed for compensating curvature of field from the centre to the very edge of the periphery. While realising a super-wide field of view, it assures a sharp and clear image across the entire field of view. The super-wide field of view allows you to take in a wide-sweeping view of star clusters or galaxies, while individual stars can be clearly seen as sharp points.
Using three ED (Extra-low Dispersion) glass elements in each tube, chromatic aberration that causes colour fringing is compensated at the very edge of the field of view, realising a contrast-rich and high-resolution image
High-quality multilayer coating which features uniformly high light transmittance across the entire visible range, is applied to all lenses and prisms to realise a more natural, clearer view. It reproduces the colours of stars in the night sky with fidelity.
Abbe-Koenig prisms that feature total reflection on all surfaces and have a high transmission rate are employed, for a brighter field of view
Applying a phase-correction coating on roof (Dach) surfaces of Abbe-Koenig prisms, which compensates phase shifts of light when reflecting inside prisms, results in high-resolution and high-contrast images
Optical design that realises both a super-wide field of view and long eye relief. The super-wide field of view can be enjoyed comfortably from edge to edge, even by eyeglass wearers.
Lead- and arsenic-free glass is used for all lenses and prisms
Turn-and-slide rubber eyecups with six-clicks facilitate easy positioning of the eyes at the correct eyepoint
Dioptre adjustment ring with index for easier adjustment
Waterproof structure that will not be affected if submerged in water to a maximum depth of 5m/16.4 ft for 10 minutes. (Under Nikon's testing conditions. Not designed for underwater usage.)
Airtight structure with a nitrogen-filled body that prevents the inside of the optical system from fogging and resists mould even with significant changes in temperature
Magnesium alloy is utilized, realising a sturdy, lightweight body that facilitate handheld viewing
55mm filter (P=0.75) can be attached to objective lens
Comes with an exclusive tripod adaptor TRA-4 that enables attaching to a tripod
