Celestron TrailSeeker ED 10x42mm Binocular - Birding, Outdoor

Celestron TrailSeeker ED 10x42mm Binocular - Birding, Outdoor arrives as a refined companion for birdwatchers and outdoor enthusiasts seeking bright, detailed views in a compact package.

The TrailSeeker ED features high-quality BaK-4 prisms and Fully Multi Coated (FMC) lenses that maximise light transmission and contrast for crisp images across the field. With an objective diameter of 42 mm and an exit pupil of 4.27 mm, these binoculars perform well in low-light conditions, supported by a twilight factor of 20.2 and a relative brightness of 18.23.

Comfort and ergonomics are carefully considered in the design: the binoculars weigh 666 g and measure 139.7 mm high, 124.5 mm wide and 50.8 mm deep, making them easy to carry and handle during long observation sessions. The eye relief is 1.5 cm and the diopter compensation offers ±3 adjustment to help you achieve sharp focus tailored to each eye.

Optical convenience is also strong, with an apparent field of view of 6.5° and a real field of view of 103 m at 1000 m, giving expansive vistas for birding and landscape watching. The 10x magnification brings distant subjects close while the closest focusing distance of 2.5 m lets you observe nearby details, useful for insects, plants or perched birds.

The TrailSeeker ED is built for outdoor use: it is waterproof and supports tripod mounting for steady, long-duration viewing. The interpupillary distance is adjustable from 5.6 cm to 7.4 cm so multiple users can quickly adapt the binoculars for comfortable viewing.

This package is travel-ready with a supplied carrying case, neck strap, cleaning cloth and lens caps to protect your optics in the field. At 666 g it balances sturdiness and portability for day hikes, travel and fieldwork.

Use cases include serious birding, wildlife observation, hiking, nature photography scouting and general outdoor surveillance where image clarity, brightness and weather-resistant construction matter. The tripod-ready feature also makes these binoculars suitable for long stargazing sessions or coastal watches.
