Celestron’s award-winning Nature DX binocular gets a major
upgrade with the addition of ED objective lenses. Nature DX ED’s optical
performance rivals that of more expensive binoculars, at a price to fit
your budget.
This versatile, all-around binocular is a great choice for the trail,
the stadium, the arena, or just about anywhere you want a close-up view
of the action without sacrificing brightness or detail. It’s an
especially great companion for nature observation and bird watching,
with ED glass that helps you spot the subtlest field markings and a
close focus of just 6.5 feet.
ED Objective Lenses
Extra-Low Dispersion (ED) glass virtually eliminates chromatic
aberration, also known as color fringing, a visual defect common in
binoculars. Nature DX ED delivers razor sharp images, even at the edges
of the field of view. ED glass is also known for producing images with
outstanding, true-to-life color.
Not all ED glass is created equal. Celestron’s high quality ED glass
delivers visibly brighter, sharper images compared to non-ED binoculars.
The difference is especially apparent in low light conditions, such as
at dawn or dusk.
Coatings and Prisms
Nature DX ED features fully multi-coated optics. A binocular can be
considered “fully multi-coated” when all air-to-glass surfaces are
coated with multiple layers of anti-reflectivity coatings so that the
maximum amount of light passes through the glass to the eye.
The prisms inside Nature DX ED are made of high quality BaK-4 glass
with phase coatings applied so that more light is reflected off their
internal faces and passes through to the eye.
Taken together, the fully multi-coated lenses and BaK-4 prisms
maximize light transmission for the remarkably bright, highly detailed
images. The ED objective lenses further enhance these features,
especially in low light conditions.
The Body
A durable rubber armored, polycarbonate housing protects your Nature
DX ED binoculars from damage without weighing you down. Viewing through
Nature DX ED is comfortable for both eyeglass wearers and non-eyeglass
wearers, thanks to the durable twist-up eyecups. Twist through multiple
click stops to find the position that works best for you. What’s more,
the binocular is fully waterproof and filled with dry nitrogen gas to
prevent internal fogging of lenses. Nature DX ED can stand up to even
the toughest outdoor conditions.
Perfect for a Variety of Uses
Nature DX ED 8x42 features a close focus of just 6.5 feet, making it
perfect for viewing birds, butterflies, plants, or other nearby
subjects. For distance viewing, the 8x42 model offers a wide field of
view so you can easily follow subjects as they move with less need to
move the binoculars.
Ways to Observe
Carry your Nature ED on the comfortable included strap. It’s also
tripod-adaptable, so you can mount it on any standard photographic
tripod for extended viewing or digiscoping (photography through the
eyepiece). The tripod adapter is sold separately. The binocular also
includes a protective padded nylon case for storage and transport.
