Celestron Nature DX Review: Affordable 8×42 Optics
The Celestron Nature DX 8×42 pairs a wide, stable view with close focusing, comfortable eye relief, and weather protection at an approachable price. Model 71332 is aimed at beginning and intermediate birders, hikers, travelers, and families who want a capable roof-prism binocular without paying for premium ED glass.
The basic specifications are well chosen for general outdoor use. Eight-power magnification is easier to hold steady than 10x or 12x, the 42mm objectives gather useful light, and the 388-foot field of view at 1,000 yards makes moving subjects easier to locate. Celestron also lists a 6.5-foot close-focus distance and 17.5mm of eye relief, two figures that expand the binocular’s appeal for feeder watching, insects, flowers, and eyeglass wearers.
Fully multi-coated optics and phase-coated BaK-4 prisms are more sophisticated than the simple coatings found on many entry-level binoculars. The body is nitrogen filled, waterproof, fogproof, rubber armored, and tripod adaptable. At 22.2 ounces, it is light enough for a full-size 8×42, although it still deserves a proper strap or harness during long walks.
Pros
- Wide 388-foot field of view makes birds and moving wildlife easier to find.
- 6.5-foot close focus is useful for nearby birds, plants, insects, and exhibits.
- 17.5mm eye relief and multi-stop eyecups accommodate many eyeglass wearers.
- Waterproof, nitrogen-filled body supports dependable outdoor use.
- Phase-coated BaK-4 prisms and fully multi-coated optics offer strong value.
Cons
- Standard glass shows more color fringing than well-executed ED binoculars.
- Polycarbonate construction feels less premium than magnesium or metal chassis designs.
- The included case is practical but basic for rough travel.
- Twenty-two ounces is portable, not truly pocket-size.
Entry-Level Price, Serious Optical Basics
The Nature DX succeeds because Celestron spends its optical budget on fundamentals. BaK-4 roof prisms are phase coated to improve contrast and resolution, while fully multi-coated lenses increase transmission across the optical path. Those features cannot guarantee premium edge sharpness or perfect color control, but they provide a solid foundation for a bright, useful image that is clearly above toy binoculars and many lightly coated budget models.
An 8×42 configuration is especially forgiving. The 5.25mm exit pupil delivers a comfortable view in ordinary daylight and remains useful under tree cover or in the early evening. Eight-power magnification also reduces visible hand tremor and gives a deeper apparent field than higher-power designs. For new users, that steadiness often creates a more satisfying experience than additional magnification because the subject is easier to find, follow, and keep sharp.
The main optical compromise is the absence of ED glass. High-contrast edges can show more color fringing than they would through a premium binocular, and the outer field may soften sooner. Those limitations are appropriate to the price rather than disqualifying. The Nature DX is designed to reveal useful detail across a broad range of activities, not to compete directly with optics costing several times more.
Close Focus and a Bird-Friendly Field of View
Celestron’s 388-foot field of view at 1,000 yards is one of the Nature DX’s most practical strengths. A wide view helps a beginner get on target quickly when a bird moves between branches or a deer crosses a clearing. It also makes landscape scanning more natural and reduces the sense of looking through a narrow tube. Experienced birders value field width for the same reason: locating the subject is often harder than magnifying it.
The 6.5-foot close-focus distance adds another dimension. Backyard birds, butterflies, flowers, museum displays, and trail details can be viewed without backing far away. Close focus is not simply a novelty; it allows one binocular to cover both feeder distance and broader landscape observation. At very close range, the focus wheel requires more movement and depth of field becomes shallow, but the capability remains unusually useful in an affordable 8×42.
The center-focus design and right-eye diopter follow a familiar setup routine. Focus the left eye with the central wheel, adjust the right eye with the diopter, and then use the center wheel for normal observation. Taking time with this initial calibration produces a sharper, less tiring image and prevents the eyes from compensating for a poorly set binocular.
Comfortable Controls for Long Outings
The Nature DX provides 17.5mm of eye relief and twist-up eyecups with multiple stops. That combination is well suited to users who wear glasses, although individual frames still determine whether the entire field is visible. Non-eyeglass users can extend the cups to block stray side light and position the eyes at the correct distance. The multi-stop mechanism is more flexible than a simple fully-up or fully-down design.
The rubber-armored polycarbonate housing measures approximately 5.3 by 4.9 by 2 inches. It is compact enough for a glove box or day pack, but not a jacket-pocket binocular. The 22.2-ounce weight is comfortable with a padded neck strap for moderate walks; a harness is better for all-day birding because it prevents the binocular from swinging and keeps the weight off the neck.
Handling is simple rather than luxurious. The bridge, focus wheel, and armor are designed for function and affordability. That is a virtue for a first serious binocular: there are no electronic modes, batteries, or complicated controls to manage. Users can concentrate on finding subjects, adjusting focus, and learning how light and distance affect the view.
Weather Protection, Accessories, and Value
Celestron nitrogen fills the Nature DX and describes it as waterproof and fogproof. Internal gas purging helps prevent condensation on interior surfaces when temperature and humidity change, while the sealed body protects against rain and splashes. The rubber armor adds grip and shields the housing from everyday knocks. It should still be dried before storage and kept out of prolonged submersion or extreme heat.
The package includes a neck strap, objective caps, rainguard, padded nylon case, lens cloth, and instructions. The accessories cover immediate use, although frequent hikers may eventually upgrade the strap or add a harness. The binocular is tripod adaptable, which can be useful for shared viewing, astronomy, mobility support, or extended observation from one location.
Value is the defining point. The Nature DX offers the specifications that most new birders actually need: a steady magnification, broad field, useful close focus, comfortable eye relief, weather protection, and straightforward controls. More expensive binoculars can improve color correction, edge sharpness, low-light contrast, and mechanical refinement. The Celestron earns its place by delivering a coherent, outdoor-ready experience before those improvements become essential.
Conclusion
The Celestron Nature DX 8×42 is a sensible first serious binocular and a strong budget option for anyone who values ease of use over prestige. Its 388-foot field, 6.5-foot close focus, 17.5mm eye relief, phase-coated BaK-4 prisms, and waterproof nitrogen-filled body address the practical needs of birding, hiking, travel, concerts, and wildlife viewing.
Buyers should expect some optical and material compromises compared with ED-glass models, particularly around color fringing and edge refinement. Those tradeoffs do not undermine the central appeal. For an approachable price, the Nature DX provides a stable, bright, and versatile view that can support a new hobby rather than limiting it.
