Celestron Echelon 20x70 Binoculars - Waterproof, Japanese Optics

Celestron Echelon 20x70 Binoculars arrive as a high-performance, waterproof optic designed for serious astronomy and long-distance observation.

These Celestron Echelon 20x70 binoculars combine 20x magnification with a large 70 mm objective diameter to deliver bright, detailed views under low-light conditions, confirmed by a twilight factor of 37.42 and brightness of 12.25 cd/m².

The optics use high-quality BaK-4 prisms and Fully Multi Coated (FMC) lenses, ensuring excellent contrast, reduced reflections, and sharp images across the field. The apparent field of view measures 3° (52 m at 1000 m), making them well suited to scanning the night sky or distant landscapes.

Designed for comfortable extended use, the binoculars offer an exit pupil of 3.5 mm and 19.5 mm of eye relief (1.95 cm), plus diopter compensation of ±4 to fine-tune focus for individual eyesight. The closest focusing distance is 100 m, reflecting their optimization for distant observation.

Built for outdoor conditions, the robust black housing is waterproof and supports tripod mounting for steady views during astronomy sessions or long observation periods. Adjustable interpupillary distance ranges from 5.8 cm to 7.2 cm to fit a wide range of users.

The package includes practical accessories such as a carrying case, neck strap, cleaning cloth, and lens caps, and the binoculars weigh 1.84 kg with dimensions of 258 mm (W) x 222 mm (D) x 84 mm (H), making them portable for field use when paired with a tripod.

Typical use cases include deep-sky and moon observation, birding at long distances, coastal and maritime surveillance, and scenic landscape viewing where high magnification and light-gathering ability are required. The sturdy waterproof build also makes them suitable for shore-based and variable-weather outings.
