Not that heavy to hold for a 10x binocular

Not to heavy. Like that it Eye/ Lense Covers to keep dust out. Only wish the Eye cover was attached like the Lense Cover. Then, couldn't lose it.

Not that heavy to hold for a 10x binocular

By DANIEL M.

Not to heavy. Like that it Eye/ Lense Covers to keep dust out. Only wish the Eye cover was attached like the Lense Cover. Then, couldn't lose it.

Discover the unparalleled viewing experience offered by the 10x42 Regal ED Roof Prism Binoculars, a top-tier product from Celestron's esteemed Regal ED line. These binoculars are engineered with Extra-Low Dispersion (ED) objective lenses and flat field lenses, delivering sharp, expansive views with high color accuracy.

Designed for the discerning birder, these binoculars offer vivid, true-to-life color resolution and expansive fields of view, making it easy to track fast-moving objects. The 4.9-foot close focus distance allows for an intimate view of subjects that suddenly appear close by. However, the Regal ED binoculars aren't just for birders; they're versatile enough to meet the demands of a wide range of outdoor activities.

The ED Glass Objective Lenses in these binoculars virtually eliminate chromatic aberration or color fringing, a common issue when different wavelengths of light disperse while passing through optical lenses. This results in images with outstanding, true-to-life color. Celestron's high-quality ED glass lenses deliver visibly brighter, sharper images compared to non-ED binoculars, a difference that's particularly noticeable in low light conditions like dawn or dusk.

The Regal ED binoculars also feature flat field optical technology, which counteracts the natural field curvature shown by convex lenses, delivering a broad, linear image right to the edges of the field of view.

The binoculars are fully multi-coated, meaning all air-to-glass surfaces are layered with anti-reflectivity coatings to maximize light transmission. The high-quality BaK-4 glass prisms inside the Regal ED have phase coatings applied to reflect more light off their internal faces, resulting in remarkably bright, highly detailed images.

The ergonomic design of the Regal ED binoculars features a magnesium alloy body that protects your binoculars from damage without adding unnecessary weight. The durable metal twist-up eyecups make viewing comfortable for both eyeglass wearers and non-eyeglass wearers. The binoculars are waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses, making them resilient in even the toughest outdoor conditions.

The Regal ED 10x42 binoculars feature a close focus of just 4.9 feet, making them perfect for viewing nearby subjects like birds, butterflies, and plants. For distance viewing, the wide field of view allows you to easily track moving subjects with less need to move the binoculars.

Carry your Regal ED binoculars with the included padded strap or on the cross-body carry harness for additional comfort. They're also tripod-adaptable for extended viewing or digiscoping. The binoculars come with a one-piece eyepiece cover to protect your lenses from rain, dust, and other substances, and a high-quality hard shell case for secure storage and transport.
