Nikon WX 7x50 IF

Nikon WX 7x50 IF | A wide, sharp view of the night sky

A view of the night sky that loses sharpness towards the edges hides detail just where a wide field is most useful. The Nikon WX 7x50 IF is an astronomical binocular with 7x magnification and 50mm objective lenses, made to keep stars crisp across the view. Its field-flattening optics address edge softness, while three ED glass elements in each half of the binocular control colour fringing and preserve contrast. This is a specialist instrument for astronomy, particularly for observers who like to take in a broad sweep of sky rather than focus on a small patch at a time. The 66.6° apparent field of view suits scanning star fields, and the 188-metre field at 1,000 metres gives a sense of how much scene fits within the view. The binocular’s optical correction also matters when you’re comparing stars near the centre with those near the edge: fine colour differences remain visible across the field. Nikon uses multilayer coatings across the lenses and prisms to transmit light throughout the visible range, for a bright, natural-looking image. A magnesium-alloy body and adjustable rubber eyecups round out a design intended for extended observing sessions. It’s a substantial specialist instrument, with optical details aimed squarely at seeing more of the sky clearly.

Highlights

• Field-flattening optics: The optical system corrects for the loss of sharpness that can occur towards the edges of a binocular view. That matters during wide-field astronomy, where you’ll often look across the whole scene rather than keep a star centred.
• ED glass in both halves: Each side contains three ED glass elements to limit chromatic aberration. This supports a high-resolution, high-contrast image and keeps subtle differences in star colour visible closer to the edge of the view.
• Broad 66.6° apparent field: The wide apparent field is well suited to sweeping across star fields and taking in a larger area of sky at once. The stated field of view is 188 metres at a distance of 1,000 metres.
• Multilayer optical coatings: Nikon applies multilayer coatings to the lenses and prisms. They support high light transmission across the visible range, contributing to a bright image with natural-looking colour.
• Adjustable rubber eyecups: The eyecups twist and slide, with six click-stop positions for setting the viewing distance to your preference. That adjustability is useful when settling in for a longer session at the binoculars.
• Magnesium-alloy housing: The body combines a robust construction with a relatively light material. It’s a considered balance for an instrument intended to be held during extended sky observation.
