The Celestron TrailSeeker ED 8x42 is a roof-prism binocular built for birders, hunters and general outdoor use. Its edge-to-edge sharpness comes from extra-low dispersion objective glass, fully multi-coated optics and phase- and dielectric-coated BaK-4 prisms. The 8x magnification and 42mm objectives give a bright, stable view that holds up at dawn and dusk. It sits well above budget 8x42s on glass quality while staying lighter on the wallet than premium European models.

The TrailSeeker ED 8x42mm is a roof prism binocular with Extra-Low Dispersion (ED) objective lenses. The ED glass reduces chromatic aberration, also known as color fringing. It gives edge-to-edge sharpness with good color correction, and the effect is most noticeable in low light such as dawn or dusk.
The optics are fully multi-coated, so every air-to-glass surface has multiple anti-reflective layers. The BaK-4 prisms have both phase and dielectric coatings. Together these let more light pass through to the eye.
The body is lightweight magnesium alloy with a rubber coating. It is fully waterproof and filled with dry nitrogen gas to prevent internal fogging. Twist-up eyecups with multiple click stops suit eyeglass wearers and non-wearers. Close focus is 6.5 feet, and the binocular has a wide field of view for following moving subjects. It can be mounted on a standard photographic tripod with an adapter, which is sold separately.
