Product Description

If you want something smaller than a full size binocular, but with more performance than a 20 or 25mm compact, this very affordable Celestron 10x32mm Nature DX is the perfect compromise. It is a surprisingly good high power 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 10x32mm Nature DX is a lightweight companion for everyday birding and watching sports, for hiking or camping, or for tucking into a suitcase on a vacation trip. The Celestron 10x32mm Nature DX is usable anywhere and anytime a good high power binocular is needed to bring distant sights closer, and 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 10x32mm 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.

Features of this binocular . . .
  • 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.
  • Eye relief. Eye relief is specified at 14mm, although will typically measure a mm or two less due to the eyepieces being recessed to keep them from getting scratched in use. There will be some vignetting for eyeglass wearers.
  • Field of view. The field of view is a 5.8° across (304' at 1000 yards), making this Celestron 10x32mm Nature DX roof prism better suited to sweeping distant fields, marshes, shore lines, and the sky, rather than taking in wide vistas.
  • Good close focus. Focuses down to 6.5'. This close focus makes close-in birding and butterfly watching possible, although the 5.8° field may limit its usefulness at very close distances (the field is only 8" wide at 6.5').
  • 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.
