Binocular Celestron Trailseeker ED 8X42.
The 8x42 TrailSeeker ED binocular offers high-end outdoor performance, a perfect choice for avid birders, hunters and outdoor enthusiasts. TrailSeeker ED includes optical, mechanical and ergonomic features that make it comparable to binoculars costing two to five times as much.
ED objective lenses.
Extra-low dispersion (ED) glass virtually eliminates chromatic aberration, also known as color fringing, a common visual defect in binoculars. TrailSeeker ED offers edge-to-edge sharpness with excellent color correction and sharp images.
Not all ED glass is created equal. High quality ED glass from Celestron provides visibly brighter and sharper images compared to non-ED binoculars. The difference is especially evident in low light conditions, such as at dawn or dusk.
Coatings and Prisms.
TrailSeeker ED features fully coated optics and dielectrically coated BaK-4 prisms. A binocular can be considered "fully multi-coated" when all air-to-glass contact surfaces are coated with multiple layers of anti-reflective coatings so that the maximum amount of light passes through the glass to the eye.
The prism inside the TrailSeeker ED is made of high quality BaK-4 glass with dielectric coatings so that more light is reflected off the prism and effectively deflected toward the eye. Taken together, the multiple coatings and BaK-4 prisms maximize light transmission for the brightest, most detailed images.
The body.
TrailSeeker ED is composed of lightweight, durable magnesium alloy. Its rigid, rugged structure is rubberized to withstand tough use in the field. In addition, the binocular is fully waterproof and nitrogen-filled to prevent internal lens fogging. TrailSeeeker ED can withstand even the toughest outdoor conditions.
Viewing through TrailSeeker ED is comfortable for both eyeglass and non-eyeglass wearers, thanks to the durable eyecups.
Perfect for a variety of uses.
The TrailSeeker ED has a close focus perfect for viewing birds, butterflies, plants or other close subjects. But this 8x42 binocular also offers the magnification you need to get excellent views of subjects at a distance, 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 adventure companion.
Ways to observe.
TrailSeeker ED includes a neck strap and 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 longer viewing or digiscoping sessions (tripod adapter sold separately). The binocular also includes a protective soft case for storage or transport.
