Description
”These really are a great pair of long distance and astronomy binoculars.” - Jason Whitehead, BestBinocularsReviews.com
Not all binoculars are created equal, especially when they are expected to perform well in low light conditions. Observations during twilight and at night require larger optics to collect as much light as possible, but big lenses alone are not enough to ensure a superior viewing experience. It also takes quality glass and rugged construction to keep your binoculars safe and working well for years to come.
Celestron’s large-aperture Echelon series binoculars were designed for use in low light conditions. Whether you are long-range glassing across a field or valley, or gazing at the splendors of the Milky Way, a pair of Celestron Echelon binoculars will get the job done. With an exit pupil of 3.5 mm, these binoculars deliver an amazing amount of light allowing you to see the most detail possible.
The Echelon 20x70 model offers the highest magnification in the Echelon Series. Choose this model for picking out small subjects at the longest distances, or for high-magnification viewing of celestial objects.
Superb Optical Quality
Celestron Echelon binoculars sport high quality 70 mm 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.
Quality Construction
Each Echelon binocular housing is made of aluminum alloy, to keep them strong yet lightweight, an important factor when considering a big binocular purchase. Durable rubber armor covers the aluminum 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.
Includes Waterproof Hard Case
Echelon binoculars come with a high quality waterproof hard case for ultimate protection against dust, moisture, and rough handling. A molded foam insert cradles the binoculars perfectly, keeping them safe and sound no matter where your journeys take you!
Individual Focus
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.
Tripod Adaptable
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.
