The Celestron TrailSeeker ED Binocular 8x42 feature Extra-Low Dispersion (ED) glass which virtually eliminates chromatic aberration, also known as color fringing, a visual defect common in binoculars. TrailSeeker ED delivers edge-to-edge sharpness with excellent color correction and razor-sharp images.

Not all ED glass is created equal. Celestron’s high quality ED glass delivers visibly brighter, sharper images compared to non-ED binoculars. The difference is especially apparent in low light conditions, such as at dawn or dusk.

TrailSeeker ED features fully multi-coated optics and phase- and dielectric-coated BaK-4 prisms. A binocular can be considered "fully multi-coated" when all air-to-glass surfaces are coated with multiple layers of anti-reflectivity coatings so that the maximum amount of light passes through the glass to the eye.

The prism inside TrailSeeker ED is made of high quality BaK-4 glass with both phase and dielectric coatings so that more light is reflected off the prism and diverted through the eye. Taken together, fully multi-coatings and BaK-4 prisms maximize light transmission for the brightest, most detailed images possible.

TrailSeeker ED is composed of lightweight and durable magnesium alloy. Its tough, rigid frame is coated with rubber to stand up to hard use in the field. What’s more, the binocular is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses. TrailSeeeker ED can stand up to even the toughest outdoor conditions.

Viewing through TrailSeeker ED is comfortable for both eyeglass wearers and non-eyeglass wearers alike, thanks to the durable twist-up eyecups. Twist through multiple click stops to find the position that works best for you.

TrailSeeker ED features a close focus of just 6.5 feet, making it perfect for viewing birds, butterflies, plants, or other nearby subjects. But this 8x42 binocular also offers the magnification needed to get great views of distance subjects, plus a wide field of view so you can easily follow them as they move. No matter how you choose to observe, this versatile binocular is an excellent all-around performer.

TrailSeeker ED includes both a neck strap and a carrying harness so you can choose the option that's most comfortable for you. It's also tripod adaptable, so you can mount it on any standard photographic tripod for extended viewing or digiscoping sessions. (Tripod adapter sold separately.) The binocular also includes a protective soft case for storage or transport.

Bought for our daughter, as I already have a pair and they are fantastic and she had serious binocular envy 😅.
She is absolutely delighted with her bins. They have such excellent clarity and focus, a joy to use. Thank you so much.
