Our take on the Celestron COSMOS™ Tree of Life 8 x 25 Binoculars by Crutchfield's Dave Bar
A closer view when you're traveling light
From bird watching in the backyard, to hiking the Appalachian trail or following the on-field action of your favorite athlete, Celestron's COSMOS Tree of Life 8 x 25 binoculars are an excellent all-around choice. Their high magnification and generous field of view give you a clear, detailed look at faraway objects. Plus, their compact size along with a waterproof and fogproof design means you can use them worry-free under just about any conditions.
These binoculars were designed to deliver distortion-free images. Fully multi-coated lenses and phase-coated BaK-4 prisms minimize light loss for greater brightness and contrast. Eyeglass wearers can better appreciate the view, too, thanks to twist-up, multi-stop rubber eye cups. Their non-slip, rubberized exterior makes them easy to grip. Celestron's rugged, high-quality construction is even backed by a lifetime warranty to ensure long-lasting performance.

Overview: The COSMOS Tree of Life 8x25 binocular by Celestron is a lightweight, waterproof binocular with fully multi-coated optics, that can be used for observing nature and wildlife. The 8x25 model features a desert sand-colored rubber-armored coating for a sure grip, and comes with a neck strap, rain guard, objective lens caps, and a soft, padded carrying case.
Waterproof: The COSMOS Tree of Life binocular is waterproof, fogproof, and nitrogen purged, allowing you to use them in humid or wet conditions without worry.
BaK-4 Prisms: The high quality BaK-4 prisms are phase coated, which increases contrast and resolution. The binocular includes fully multi-coated optics for great image detail, and brighter images, even in low light.
Focus Knob: The COSMOS Tree of Life binocular has a smooth, central focus knob for bringing your subject into focus.
Diopter Ring: The right eyepiece has a +/-4 diopter ring for adjusting the binocular to your eyesight. A diopter index indicates the "0" position, as well as "+" and "-" positions.
Twist-up Eyecups: The twist-up eyecups accommodate both eyeglass and non-eyeglass wearers. For those who don't wear eyeglasses, the eyecups twist counterclockwise to the full up position. For eyeglass wearers, the eyecups provide the widest field of view in the down position. There is also a middle click-stop position, which may suit other users better.
