They are hand-assembled in the USA and utilise Celestron's proprietary XLT coating technology for amazing optical performance. As well as this, the 3.5mm exit pupil means that the Celestron Echelon 20x70 Binoculars will allow you to see amazing details, even in the shadows.

Key Features: Celestron Echelon 20x70 Binoculars
Superb Optical Quality
Celestron Echelon binoculars sport high quality 70mm objective lenses made in Japan. Superior BaK-4 prisms were chosen for maximum contrast and sharpness, and all air-to-glass surfaces are multi-coated with Celestron’s proprietary XLT optical coatings—the same high transmission coatings used on our observatory-grade telescopes to increase contrast and resolution.
Assembled in the USA
Celestron Echelon binoculars are manufactured using quality Japanese optics and are assembled by hand by skilled technicians in Southern California.
Each Echelon binocular housing is made of aluminium alloy, to keep them strong yet lightweight, an important factor when considering a big binocular purchase. Durable rubber armour covers the aluminium housing for a slip-free grip and protection against the occasional bump or ding. These binoculars are fully waterproof and are nitrogen-purged to seal the optics against fog, dew, and other forms of moisture. This means you can use your Echelon binocular in damp conditions without having to pack up and call it a day when unexpected weather makes an appearance.
Waterproof Hard Case
Echelon binoculars come with a high quality waterproof hard case for ultimate protection against dust, moisture, and rough handling. A moulded foam insert cradles the binoculars perfectly, keeping them safe and sound no matter where your journeys take you!
Echelon binoculars use an individual eye focus system, enabling you to rotate each eyepiece to set the proper focus for your right and left eye. Once set, you should be able to use your binoculars at a moment’s notice and focus sharply at infinity, the normal distance desired for long-range observations. Should you wish to share your binocular with others, it is fast and simple to adjust the focus for their vision requirements.
Extended Eye Relief
The Celestron 20x70 Echelon Binoculars have 19.5 mm of eye relief, making them comfortable for all users, whether they wear eyeglasses or not. The rubber eyecups position your eyes at the perfect distance from the optics for a full field of view.
Echelon binoculars are easily attached to a photographic tripod for extended observing sessions. A binocular tripod adapter (sold separately) is used to make the connection between the binoculars and a standard tripod, and is especially helpful for vibration-free observations of the night sky.
