Celestron has actually specified that these field glasses are meant for overall usage by newbies for both daytime and nighttime observations. They are, for that reason, tailored towards the spending plan end of the marketplace. In this undertaking, they have actually satisfied and exceeded expectations. This might assist us to suggest them in the spending plan area of our finest binocular guide.

Because of their lightweight construction and small size, they lend themselves to being used by children, which would put them into contention for our best binoculars for kids guide. But although they’re lightweight, they appear to be well made, with rugged outer armor, and are rated as waterproof on the manufacturer’s website.

The inclusion of phase coatings on the glass is unusual at this price point, and we found the clarity of these binoculars to be surprisingly good.

We tested the green variant of these binoculars and found the design to be visually appealing, with a light, compact form. Easily capable of being chucked in a rucksack for casual viewing while out walking, etc, these binoculars seem to fit their design brief well.

Design & Comfort

• Durable polycarbonate housing
• Lightweight
• Waterproof

The Celestron Nature DX 8x42mm binoculars weigh just 1.39 pounds (626 grams) and are small enough to go in an oversized pocket, making them very easy to carry on a long walk. They are sturdily built and have a waterproof casing with a good grippy material right where you need it. They fold out very smoothly, and the focus wheel is nicely weighted.

For their price, we were pleased with how nice they felt to use. It’s possible to use them while wearing gloves, which was lucky as part of our test included a beach walk in high winds, where they coped really well with being taken in and out of a coat pocket as birds and views were explored.

The Celestron Nature DX 8x42s come with a small shoulder bag, which seems to be resilient to most types of inclement weather. Also included is a neck strap made of thin nylon with the usual plastic adjusters. We found this to be OK in use: the Celestron Nature DX 8×42 is so light that the plastic cushion is enough to spread its weight evenly, preventing neck aches. The child helping with our test found them comfortable even after a five-mile walk with them around their neck.

The eyecups are twistable to enable glasses to be worn while in use, and are stiff enough to stay in place after adjusting. There was 0.9 inches (22.9 millimeters) of eye relief, and we found this enough to be comfortable for most of our testers.

They look more expensive than their actual price, and the design is compact and functional. Our test pair came in green, which further added to their appeal.

Optics

• BaK-4 phase-coated prism glass
• Fully multi-coated lenses
• Close focus of 6.5 feet

The Celestron Nature DX 8x42s have phase coatings on the prism glass. This is unusual at this price point and is a welcome addition. In our tests, this helped to provide impressive clarity and sharpness for a binocular at this price point.

The 8x magnification is more than enough for beginners, and for amateur birdwatchers and astronomers. This level of magnification helps keep the binoculars small and lightweight, and also helps with getting sharp views even without a tripod — useful if the binoculars are to be used by the whole family.

The objective lens diameter of 42mm lets in enough light during the day to enable the binoculars to be used well into dusk. We found that the image is sharp across the center of view but does soften toward the edges. This is where the low price really shows its effect on the overall quality of the image, although the coatings are able to provide surprising resolution and decent contrast for a budget bino.

On a dark, overcast day during our tests, the 42 mm lens gathered enough light to present a reasonable amount of detail, but as the light faded, so did the sharpness of the image. Celestron has a large range of magnification/lens diameters in its Nature line, and it may be worth trying out some of the larger, more powerful models in the range, such as the 10x50mm variant.

With an angular field of view of 7.4 degrees, the Celestron Nature DX 8x42s are about average in this area. Because they are small, the interpupillary distance is limited, so we found that an observer’s eyes have to be quite close together to be comfortable to use. This would make them particularly well-suited for children.

What we saw

• Easy to carry and quick to focus
• No problems with fogging
• Poor performer in low light

We tested the Celestron Nature DX 8x42s over a week-long period. During this time, we found their small size and low weight meant that you could forget you were carrying them at times, and they enhanced activities rather than causing problems or niggles. Our locations included a visit to the Jurassic coast, where we found the usual seabirds and ships, but also fossils on the side of the cliffs. They are so unobtrusive that we found we were using them while walking, when other, heavier models would be in a rucksack and therefore less accessible.

They seemed to be pretty well sealed against the elements, and at one point, retreating to a cafe to avoid bad weather, we found no fogging, which we were pleased with.

The only real problems encountered were that the neck strap came loose and the small plastic binder dropped off, causing the tester to nearly drop the binoculars. They also gave us disappointing low-light performance. We found that as light levels dropped, so did the sharpness of the images. Considering the price, though, this isn’t too much of an issue.

Verdict

The inclusion of phase-coated prism glass at this price is unusual and is a welcome addition to Celestron’s overall quality and usability. They are small enough to be comfortable for extended use by both adults and children. The price is very competitive, and if you are just starting out in the bird-watching hobby or are thinking of getting into some casual lunar astronomy, the Celestron Nature DX 8×42 is a good choice.

The low price of the Celestron Nature DX 8×42 does have some downsides. Even with fully coated lenses, the light transfer with the 42mm objective lens is less than ideal. It limits the use of the binoculars at the times of day when most bird activity is apparent, and obviously limits nighttime usability.

They are built to a price, and some of the materials feel cheap to touch, but we did find that everything worked as it should, apart from the strap falling apart.

If the Celestron Nature 8×42 isn’t for you

How we checked the Celestron Nature DX 8×42

We checked the Celestron Nature DX 8x42mm in numerous areas for both astronomy and bird-watching. The astronomy part of the test was performed in a Bortle 3 dark sky reserve throughout the current Worm Moon stage, and on place in a nature reserve on the U.K.’s Devonshire coast. The binocular was executed its speeds in all kinds of screening conditions, from brilliant, hot bright days to cooler days with downpour, in order to replicate real-world conditions.

Matt Morris is an eager astronomer, wildlife watcher and professional photographer residing in Somerset, UK. He began stargazing and birdwatching at the age of 10 with his dad who took him to bird hides and nature reserves around England. This triggered his interest in cams and optics, an enthusiasm that has actually now covered the bulk of 4 years and caused his being included in numerous nationwide photography publications for competition-winning images. Matt has actually had degrading vision in one eye over the last couple of years due to being Type-1 Diabetic. This has actually led him to establish an unique interest in optics, stimulating his enthusiasm for bird viewing and wildlife finding.
