Best overall

The main downside to the Canon 10x42L IS WP binoculars is that they are, unfortunately, rather power hungry — but that's the same with any binos with high-tech features. Here, it's the IS system that requires so much power: We got through several AAA batteries in just one sky-watching session, so you'll need to bear that in mind if you're considering purchasing these and make sure you're well stocked-up on batteries every time you venture out. It's extra weight and bulk to carry around with you, and something else to think about when you're packing up your gear. We'd say that overall the Image Stabilization is worth it, though.

We also weren't wholly satisfied with the accessories provided with these binoculars, especially considering the price point. We struggled to get the one-piece lens caps to stay in place, and the carry case was a bit basic and flimsy, so you might want to upgrade it. But overall, these are still the best stargazing binoculars on our list thanks to the astronomy-centric glass and clever image stabilization feature.

Best optical performance

Optics don't get much better than those on the Nikon Monarch HG 10x42 binoculars. But it's no surprise, when these binos come from Nikon, a brand synonymous with cameras and high-quality optical equipment. The Monarch HGs use a Field Flattener Lens System, which ensures that images are sharp all the way across the field of view and not just at one specific point. Coupled with their Extra-low Dispersion glass, which practically eliminates chromatic aberration, these binoculars are very hard to beat indeed.

During our we tested these binoculars in a range of challenging conditions and were pleased with the results every single time. Light transmission is good because the 42mm objective lenses are large enough to allow light to pass through even in twilight hours. Every single glass element also contains multilayer coatings to help improve the transmission of light, which Nikon reported as being 92% or higher..

Whilst they're undeniably pricey binoculars, we feel you're getting real quality for your money with this pair. Everything about them feels premium. The magnesium alloy body is slim and lightweight enough to slip into a coat pocket, but they feel balanced in the hand and come coated in a grippy rubberized armor. They're also entirely waterproof, so you don't need to worry about getting caught out in bad weather, and they're nitrogen-filled to prevent fogging as well.

Even the accessories feel high-quality. These binoculars come with a cushioned neck strap, objective lens caps and a premium carry case that has a secure safety catch to prevent them from falling out during transit (no relying on velcro here). We also enjoyed other unexpected details like the locking mechanism on the diopter adjustment ring which means it can't get accidentally knocked out of place. The only thing they lack is image stabilization technology.

Best for affordable stargazing

The Celestron Nature DX 12x56 binoculars are a great deal for under $250, perfect for casual wildlife spotting, bird watching or stargazing. The build quality is fantastic: They have a full rubber housing and they're completely waterproof, fogproof and nitrogen-purged. The Nature DX 12x56 binoculars include a tripod mount that could be useful for longer viewing sessions and a rain guard that protects the lenses from getting watermarked.

The focus knobs turn smoothly and easily. During our , we appreciated that the binoculars can focus on objects less than 10 feet away, making them great for spotting wildlife in your backyard. If you wear glasses, you'll appreciate the 16mm eye relief provided by the twist-up eyecups.

Despite coming in at under $250, we think the optics on the Celestron Nature DX 12x56 binoculars are comparable to some more expensive models. That's because they have multi-coated optics and BaK-4 prisms, which are generally regarded as being the best. The Nature DX are only let down by their lack of sharpness, which may be disappointing for more advanced or professional users, but if you're a casual user we think these binos are amongst the best you can buy.

If you want a high-quality pair of binoculars for bird watching or wildlife watching and can forgo some level of sharpness that more expensive models can provide, these are attractive. They are also suitable for sky watching and, thanks to the rubber armoring, are hardy enough to be taken anywhere without worrying about the elements.

Best binoculars under $300

We think the Celestron TrailSeeker 8x42 binoculars make a great pair for amateur astronomy, whilst also having the flexibility to be used for a range of other pursuits. Their price point sits just above the more affordable mass-market binoculars, and this means that you get high-quality BaK-4 glass and multi-coated optics, as well as waterproofing and nitrogen purging to make these binoculars safe to use in any weather conditions.

In our we were very pleased with the build quality on these binoculars. They're constructed from a lightweight magnesium frame with rubber coating for grip and protection. They also come with a useful range of accessories, including a thick and comfortable neck strap, a padded carry case and an innovative harness strap that spreads the weight of the binoculars over your shoulders for longer viewing sessions..

If you're looking for good binoculars for stargazing, the Celestron TrailSeeker binoculars — despite coming from Celestron — might not be the best choice on the market thanks to their 8x magnification and 42mm lens diameter. Ultimately, they're at the lowest useful end, so while they're not completely useless, you won't be able to enjoy any views of deep space. We have found them capable of offering adequate views of and the Milky Way, however, thanks to their wide viewing angle..

It's also worth noting that the TrailSeeker 8x42 binoculars don't have Extra-low Dispersion (ED) glass, so we experienced a fair bit of color fringing, particularly when viewing bright objects such as . It's not a surprise at this price point, however — and Celestron do have a model with ED glass, but as you'd expect it's notably more expensive.

Their specifications make them an entry-level choice in some ways; you wouldn’t want to go any lower than their 8x magnification and 42mm objective lens size. Although the TrailSeeker 8x42 are good all-rounders, 10x50 binoculars remain the sweet spot for stargazing.

Glasses-wearers will also find this pair easy to use thanks to their generous 17mm eye relief, which can be set in three different positions depending on your preference.

Best budget binoculars

These are affordable skywatching binoculars that would be ideal for anyone just starting out who wants to get the most for their money.

In our , we found the moon looks amazing through these binoculars, easily fitting into the view with just a hint of false color. In July 2020, the UpClose G2 10x50 binoculars were very effective in spotting the naked-eye comet C/2020 F3 (NEOWISE). We managed to spot three stars within the Trapezium Cluster near the center of the Orion Nebula (Messier 42), but you'd need a pair with higher magnification if you want to see the fourth bright star in this star-forming area.

If you're on a budget, then, the UpClose G2 10x50 binoculars are a fantastic choice, particularly if you're just starting out on a stargazing hobby. They're light enough to carry around and if you're out trekking, they're ideal to throw in a backpack without adding too much extra bulk.

They're not all perfect, though; of course some corners have been cut considering the price. We've discussed the pitfalls in more detail in our review, but you'll need to adjust the alignment of the lenses (collimation) for one.

They aren't waterproof, either, and they haven't been nitrogen-purged, so we wouldn't recommend using them in inclement weather. While the rubber armor and aluminum housing is labeled as water-resistant, we certainly wouldn't like to push our luck with them. They're liable to fog up in the cold — although they were fine during a two-hour session in near-freezing conditions.

Best for moon views

Celestron is a well-respected brand with a strong reputation and the SkyMaster binoculars, including the 15x70 'giant' model, deliver excellent views at an affordable price. Despite being a bit on the heavy side, these binoculars are durable and we think they offer impressive quality for their cost.

The SkyMaster 15x70 binoculars' number one advantage is how much light they can gather. The 70mm objective lenses pull in a huge amount of light and, coupled with the 15x magnification, they're perfect for gazing at the stars with. Objects in the are much clearer than they are with less powerful binoculars, although it's worth noting that there's some blurring around the edges of the lens — a common trait of cheaper models..

They're a great choice if you wear glasses too, since the Celestron SkyMaster 15x70 binoculars have an impressive 0.7 inches (18mm) of eye relief, so you should be able to use them comfortably.

Optically the star images were excellent at the center of the field of view, but the distortion was evident towards the edges, with the stars appearing as streaks. This is not very disturbing, as one’s vision is only sharp at the center anyway, but it means that you would have to move the binoculars to explore a large starfield. To get edge-to-edge sharpness in binoculars of this size you will have to pay a great deal more.

At 11 inches (280mm) in length and weighing 3 lbs (1.36kg), we found in our that they certainly have a lot of heft. Using them handheld isn't impossible, but for maximum comfort, it's best to use a tripod with these binoculars. Their powerful magnification makes views of the moon truly stunning, and we were especially impressed by how the lunar surface looked three-dimensional..

Despite the larger 70mm objective aperture, the higher magnification of 15x reduces the apparent field of view to 4.4 degrees, compared to typical 10x50s or 12x50s that provide a degree more.

Best mid range model

The Vortex 10x50 Crossfire HD binoculars have a lot going for them. We think they're reliable and sturdy, and useful whether you're watching wildlife or doing the occasional bit of astronomy. Their design is outstanding, particularly thanks to the focusing knob that's easy to adjust even if you're wearing very thick gloves.

The eyecups, too, are a standout feature, thanks to being customizable and twistable. The eye relief goes to 17mm, which we think is very generous and useful if you wear glasses. The Crossfire HD binoculars are lightweight, too: they weigh only 1.89lbs (0.86kg) so you'll barely notice them in a backpack or in your luggage while you're traveling.

The Vortex 10x50 Crossfire HD are roof prism binoculars, which means a relatively compact and space-saving design of two tubes joined by a small hinge in the center that houses the optics and the focusing knob. The lens caps on the 50mm objective lenses are tethered to the hinge.

The Vortex Crossfire HD 10x50 binoculars provide a sharp and clear view, particularly if you're into astronomy; they make stars look like perfect pinpoints of light. You might notice some color distortion when looking at brighter objects, but this is common for binoculars in this price range. However, they offer a great balance of brightness and sharpness across the entire field of view. During our , we only observed a tiny drop-off towards the very edges of the field of view.

There are a few downsides to them, of course. Although these binoculars come with a harness, we realized during our testing that the padded case forms part of the harness so you can't use one without the other, which is a little frustrating.

Best family binoculars

It is a known fact that children have better night vision than adults, meaning they do not require high-end binoculars to see the same amount of light that an adult would with a more powerful pair. As such, the 7x magnification and 50mm objective lenses make the a great choice for kids (they're featured in our )..

Having reviewed the specs on paper, we weren't too excited about reviewing this pair of binoculars, but to our pleasant surprise, we ended up loving them in our . We think they offer a budget-friendly entry into the realm of sky-watching, and if they don't suit you, the gamble will only set you back $40.

The Celestron Cometron 7x50 are lightweight and easy to carry around, even in the small hands of a child. They are, however, not so lightweight that they will break easy: they're hard-wearing enough that they can withstand the odd bash or knock. It's worth noting, though, that they aren't waterproof, so we wouldn't recommend using them in bad weather (and they certainly wouldn't survive being dropped in a puddle).

Keep in mind that kids might find it more challenging to keep binoculars steady for a long time, so it's a good idea to pick a pair that are lightweight and comfortable for them. This makes it easier for kids to use them and helps prevent them from getting tired quickly. Alternatively, consider .

Best for magnification

The Celestron SkyMaster 25x100 are our top pick for large astronomy binoculars. They act like two 100mm (4-inch) refractor telescopes set up side-by-side, with built-in image-erecting prisms and eyepieces that rotate independently through 450 degrees rather than the combined central focus knob that you get on traditional binoculars. They also have a 15mm eye relief, which is just enough to comfortably use them with glasses.

During our , we were impressed with the breathtaking images of the night sky they provided. We were able to pick out clusters of galaxies like the Leo Triplets, Jupiter's atmospheric belts and the Sagittarius star cloud (also known as Messier 24). The multi-coated optics produce bright, clear views through the unusually large objective lens diameters.

It goes without saying that the Celestron SkyMaster 25x100 binoculars are very heavy and large. You won't be able to use them handheld, so they will need to be mounted to a tripod using the built-in tripod adapter. They're rather heavy, too, weighing in at 8.75lbs (3.97kg) which doesn't make them all that suitable for carrying around (particularly considering you'll also need to carry a tripod).

But the size is, of course, for a reason, because without binoculars this large you can't get such breathtaking views of the night sky. The only real let-downs are the disappointing lens covers and the thin carry case, but aside from those, we think these binoculars are amongst the best for astronomy.

Best for entry level astronomy

The Nikon 10x50 Aculon A211 are our top pick for entry-level astronomy. Their 10x magnification and 50mm objective lenses are ideal for stargazing, though they could also be used for observing birds or other wildlife when you're out and about.

For the price, we think the optics on these are fantastic. They utilize a porro prism design, which makes them a bit bulkier than some other options, but really maximizes the brightness of the image for stargazing. They also incorporate high-density BaK-4 glass, which is much better than the BK-7 glass that you'll more commonly find at this price point. This makes them a great-value choice for those looking to get started with astronomy.

We really enjoyed scanning the skies with these during our Stars appeared extremely sharp in the center of the field of view, with just some blurring towards the outer edges and a little chromatic aberration when viewing the moon. This is to be expected at this price point, but we don't think it would hinder the enjoyment of first-time stargazers..

If you're considering buying the Nikon 10x50 Aculon A211 binoculars, there are a couple things worth keeping in mind. First, their close focus distance is a minimum of 23 feet (7 meters), which means if you want to observe wildlife at close range, perhaps in your own backyard, they're perhaps not the best choice. They also have a fairly small eye relief at 11.8mm, which isn't great if you wear glasses.

Best for beginners

If you're looking for a fantastic pair of entry level binoculars, look no further than the Nikon Prostaff P3 8x42. We think they are of a much higher quality than their modest price tag would imply, and they're a great buy for any beginner or casual user.

The Prostaff P3 8x42 are fairly new to the market and they really stand out from the crowd due to their excellent optics — they really are a cut above the competition. Another stand-out feature is their impressive eye relief: at 20.2mm it's one of the largest on this list, making them perfect for anyone who wears glasses (or needs adjustable eyecups for comfort).

These binoculars are designed to be lightweight and durable. Made from strong fiberglass-reinforced polycarbonate resin, they have a non-slip rubber coating for a comfortable grip during long use. The shockproof design makes them resistant to damage from any accidental drops or bumps, and they are also waterproof and fog-proof, which is impressive for their affordable price.

During our , we found adjusting the focus on very easy, and we love that they offer just the right amount of resistance, even when you're wearing thick gloves. Although they don't include a tripod adaptor, their 8x magnification and lightweight design (only 572g) make them manageable without one.

The Nikon Prostaff P3 8x42 are great for casual nature watching or travel, without stressing about exceeding your luggage weight limit. However, if you plan on long nights of extended stargazing, they might not be the most suitable choice.

Best for reliability

The Nikon Action EX 12x50 binoculars are a fantastic option compared to more mainstream 10x50 binoculars as they provide a higher 12x magnification while maintaining the same 50mm aperture. The build is excellent, featuring comfortable rubber grips and a large focus knob, although the 13mm eye relief will be a little short for anyone who wears glasses.

You'll generally find that when using higher magnification binoculars, you'll get slightly duller images. That's because you're magnifying the same amount of collected light. But with the Nikon Action EX 12x50 binoculars, that's not really the case: Thanks to their multi-coated lenses and high-refractive-index prisms, their images remain beautifully bright, which is a serious plus for anyone considering binoculars with a more powerful magnification.

The Nikon Action EX 12x50, weighing in at 2.3 lbs (1.04kg), is too heavy for long bouts of stargazing, and the higher magnification will enhance any image wobble, so we advise using a .

In our , we found that these binoculars give clear and sharp images in the center, especially when looking at stars. However, you might see some distortion near the edges of the 5.5-degree field of view. Seeing Saturn's rings individually wasn't possible with this pair of binoculars, but observers can still notice clear ansae – the extensions of the rings on either side of the planet, creating an oblate shape. Overall, they offer a great viewing experience.

Best for daytime use

These are some of the finest handheld binoculars for stargazing and wildlife observation. The Extra-low Dispersion (ED) objective lenses produce aberration-free sharp images.

During our , we took them to several events, which made us appreciate how lightweight and compact they are to carry in their padded case. We tested them at a motor race and were delighted with the bright and sharp views, even at dusk.

We were equally happy with how well these binoculars worked at night. The Pleiades star cluster looked sharp and clear across the entire view, with only a slight decrease in quality towards the edges, and we didn't see any noticeable color distortion either.

This is an excellent pair of binoculars that boasts great quality for a relatively low price. You can typically pick them up for under $250, which is more expensive than some pairs on this list, but they're well worth the price. We particularly love the tough rubber armor on the outer casing of the binoculars, protecting them from water damage and the odd impact.

However, we've been let down by the quality of the Celestron Nature DX ED 12x50's eyecups. They're not very comfortable to use, and in particular if you wear glasses you'll likely find them a problem. It's not serious enough to ruin the binoculars entirely but it's something to keep in mind.
