The Celestron 8x32mm Nature DX is a right-sized and light-weight (only 18 ounce) roof prism binocular with an array of premium features that once cost many times its modest price. You get full multicoatings, phase-corrected BaK-4 prisms, nitrogen-purged waterproofing, full armor, and more. 

The Celestron 8x32mm Nature DX will tuck into a suitcase or car glove compartment for a vacation trip, as well as slip into a coat pocket for everyday birding, watching sports, hiking, and camping. The Celestron 8x32mm Nature DX is usable anywhere and anytime you need a good binocular, but a reasonable size and affordable price are mandatory. Armored and waterproof/fogproof, it takes unexpected bumps, thumps, and showers in stride.

Image quality is good, with minor field curvature. Geometric distortion (pincusioning) is essentially non-existent. Chromatic aberration is low. Colors are natural and true to life. By any standard you might care to choose - visual performance, features, build quality, feel in the hand and ease of carrying, value for money - this Celestron 8x32mm Nature DX roof prism is a good choice for anyone who is looking for a good quality less than full size high power roof prism binocular at a budget price.

• Roof prism optics. Compact H-body roof prism using quality BaK-4 prisms. Internal center focus.
• Fully multicoated optics. The optics are treated with multiple-layer antireflection coatings on all air-to-glass surfaces for good light transmission and high contrast.
• Phase-coated prisms. The image-erecting roof prisms are made of high quality BaK-4 glass, multicoated to provide the brightest possible images. The prism faces have special phase-correcting coatings for peak contrast, color fidelity, and resolution. The resulting improvement is easily seen when looking for color and detail in the shadowed areas of a silhouetted or back-lit bird.
• Waterproof and fogproof. O-ring sealed and nitrogen-purged to be fully waterproof and fogproof in summer showers and monsoon rains alike.
• Full armor. Forest green rubber armor on the rugged and lightweight polycarbonate body absorbs noise and shock and provides a good grip when wet.
• Twist-up eyecups. The rubber-rimmed eyecups twist up for use without glasses and twist back down for eyeglass or sunglass use.
• Long eye relief. Eye relief is specified at 17.5mm, although will typically measure a mm or two less due to the eyepieces being recessed to keep them from getting scratched in use. There may be some vignetting for eyeglass wearers.
• Good field of view. The field of view is a good 7.4° across (388' at 1000 yards), making this Celestron 8x32mm Nature DX as well suited to sweeping distant fields, marshes, and shore lines as it is for backyard and neighborhood birding.
• Good close focus. Focuses down to 6.5'. This close focus combines with its wide 7.4° field to make it very usable for close-in birding and butterfly watching.
• Focusing. Not a particularly fast focuser, as two turns of the ribbed focus knob are needed to move from the 6.5' close focus out to the horizon and beyond. Most of the focus knob travel occurs close-in, however, providing very precise focusing on nearby subjects. Once past 75' or so, only a touch of the focus knob is needed to move from subject to subject.
• Rotary diopter correction. A variable diopter ring on the right eyepiece allows you to match the binocular optics precisely to your individual eyesight for a sharp image.
• Tripod adaptable. For extended no-hands observing, a protective cover on the front bridge unscrews, revealing a 1/4"-20 thread hole for mounting the 18 ounce binocular on a photo tripod using an optional tripod adapter.
• Standard accessories. An eyepiece rainguard, tethered (but removable) flip-down objective lens covers, a medium width (15/16" wide) cloth neckstrap, and a soft padded nylon carrying case with belt loop and shoulder strap are standard equipment.
