The Celestron 8x42 TrailSeeker ED binocular provides high-level outdoor performance—a perfect choice for avid birders, hunters, and outdoor enthusiasts. TrailSeeker ED Bino from Celestron is packed with optical, mechanical, and ergonomic features that make it comparable to binoculars costing two to five times as much.

Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, also known as color fringing, a visual defect common in binoculars. TrailSeeker ED 8x42 Binoculars deliver 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 becomes especially obvious when using 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. 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. Together, full 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. The Celestron TrailSeeker ED 8x42 binocular is fully waterproof and filled with dry nitrogen gas to prevent internal fogging of lenses. Viewing through the Celestron TrailSeeker ED 8x42 binocular is comfortable for both eyeglass wearers and non-eyeglass wearers, thanks to the durable twist-up eyecups. Twist through multiple click stops to find the position that works best for you.

Perfect for a Variety of Uses: 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. This versatile binocular is an excellent all-around performer.
