The Celestron Nature DX ED 10x50 Binoculars pair powerful 10x magnification with light-gathering 50mm Extra-Low Dispersion (ED) objective lenses to deliver high-contrast, color-accurate images. The optical system features phase-coated BaK-4 prisms and fully multi-coated lenses, achieving a relative brightness of 25 for exceptional clarity, especially at dawn and dusk. With a generous 17.8mm of eye relief and a rugged waterproof housing, these binoculars provide comfortable, reliable viewing in any environment.
The core of the Nature DX ED's optical system is its Extra-Low Dispersion (ED) glass. This high-grade optical material virtually eliminates chromatic aberration, or color fringing, which is a common visual flaw in standard binoculars, especially around high-contrast edges. The result is a razor-sharp image across the entire 5.9° field of view with outstanding, true-to-life color fidelity that non-ED binoculars cannot match.
To ensure the brightest possible image, every air-to-glass surface in the Nature DX ED 10x50 is treated with multiple layers of anti-reflection coatings. These "fully multi-coated" optics work in tandem with high-quality BaK-4 glass prisms. The prisms are also phase-coated, a critical treatment that corrects for phase shift in the light path, increasing contrast and resolution. This combination maximizes light transmission, yielding a high relative brightness of 25 and incredibly detailed views.
A durable, rubber-armored polycarbonate housing protects the Nature DX ED from the rigors of outdoor use. The chassis is fully waterproof and purged with dry nitrogen gas to prevent internal fogging in changing temperatures. Viewing comfort is excellent for all users, with a generous 17.8mm of eye relief and multi-stop twist-up eyecups that provide a full field of view for both eyeglass and non-eyeglass wearers.
The 10x magnification is ideal for detailed observation of distant subjects, from wildlife across a field to ships on the horizon. The large 50mm objective lenses gather ample light to keep the view bright and usable even in the dim conditions of dawn and dusk. While providing this high power, the binoculars still offer a wide 309 ft linear field of view at 1000 yards, making it easy to locate and track moving subjects. For closer subjects, they can focus down to just 8.2 feet.
While the standard Nature DX offers excellent value, the Nature DX ED represents a significant step up in optical fidelity. The primary advantage of the ED version is the near-total elimination of color fringing, which results in a visibly sharper, higher-contrast image with more accurate color rendition. This difference is most apparent when viewing bright objects against a dark background or in low-light situations where maximizing every bit of detail is crucial.
They are an excellent choice for low-light conditions like dawn or dusk. The large 50mm objective lenses gather a significant amount of light, while the ED glass, fully multi-coated lenses, and phase-coated BaK-4 prisms ensure the brightest, most color-accurate image possible, helping you identify subtle plumage details when light is scarce.
The primary advantage of Extra-Low Dispersion (ED) glass is its ability to correct for chromatic aberration, also known as color fringing. This results in sharper, higher-contrast images with true-to-life color, a benefit that becomes particularly obvious at 10x magnification when viewing distant or high-contrast subjects.
Yes. They feature a long eye relief of 17.8mm and durable, multi-stop twist-up eyecups. This allows most eyeglass wearers to see the entire 5.9° field of view comfortably without having to remove their glasses.
Yes, the Nature DX ED 10x50 is tripod-adaptable. Using a standard binocular tripod adapter (sold separately) is highly recommended for extended viewing sessions, as it eliminates arm fatigue and provides a perfectly stable image, which is especially helpful at 10x magnification.
The close focus distance is 8.2 feet (2.5 meters). This allows you to get detailed, magnified views of nearby subjects, making these binoculars useful for observing butterflies, insects, or birds at a backyard feeder.
The binoculars weigh 28.4 oz (806 g). While they are substantial enough to provide a steady hold, this weight makes them comfortable to carry with the included neck strap for extended periods in the field.
