Celestron TrailSeeker ED 10x50mm Roof Prism Binoculars

TrailSeeker ED 10x50mm pairs high-end optical performance with a rugged, field-ready design. Built for serious birders, hunters, and outdoor observers, it delivers the clarity and durability you'd expect from binoculars costing two to five times as much.

ED Objective Lenses
TrailSeeker ED features Extra-Low Dispersion (ED) objective lenses designed to control chromatic aberration, the color fringing that can appear along high-contrast edges. By bringing different wavelengths of light to the same point of focus, ED glass improves resolution, contrast, and overall image fidelity.

However, the performance of ED glass depends heavily on its quality and execution. The ED elements in TrailSeeker ED are engineered to deliver meaningful gains in sharpness, contrast, and color accuracy, producing visibly brighter, cleaner images than standard optical glass. The improvement becomes especially noticeable in low light at dawn and dusk.

Coatings and Prisms
TrailSeeker ED features fully broadband multi-coated optics to maximize light transmission. Fully broadband multi-coated is the highest-quality multi-coating available; it extends the range throughout the visual spectrum.

Inside, BaK-4 prisms with both phase and dielectric coatings further enhance performance. Phase coatings correct internal light path distortions to improve resolution and contrast, while dielectric coatings increase reflectivity for higher overall brightness. Together, fully multi-coatings and BaK-4 prisms maximize light transmission for the brightest, most detailed images possible.

The Body
TrailSeeker ED features a lightweight magnesium alloy chassis that delivers exceptional strength without unnecessary weight. The rigid frame is wrapped in durable rubber armor for a secure grip and added protection in the field.

Fully waterproof and nitrogen-purged, the binocular resists rain, dust, and internal fogging, so performance stays consistent in changing conditions. Twist-up eyecups with multiple click stops allow you to fine-tune your eye position for comfortable viewing, whether you wear glasses or not.

Perfect for a Variety of Uses
TrailSeeker ED focuses down to 9.8 feet, so you can observe nearby wildlife without switching gear. At 10x magnification, it also pulls distant subjects in close, while a wide field of view makes it easier to track movement across open terrain or sky. It's built for observers who want one binocular that can handle the whole landscape.

Ways to Observe
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.

Solar Warning
• Never look directly at the Sun with the naked eye or with this optic. Permanent and irreversible eye damage may result
• Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it
• Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present
