Best 10×50 Binoculars For Astronomy

  • Swarovski 10×50 EL Binocular SWA35210

Exceptional ergonomics, to say the least. Barrels with a slim profile for 50mm caliber rifles. The image is exceptionally clear and free of distortion across the entire field of view. Crows were observed in bright light and no false colors or color fringes were discovered.


There’s also no flamboyance in this design.

Swarovski’s useful field of view is larger than that of my Zeiss and Leica lenses. I get a small bean-shaped blackout, which indicates that the eye relief is insufficient for people who wear glasses.

They’re very easy to hold on to (I use them for bird watching and this is important). As would be expected at this price point, all of the binoculars are excellent.

What matters most is how well the design matches the person’s eyes and hands. My only gripe is the lack of eye rest. It’s much, much shorter than expected. It’s not even adequate for those who wear eyeglasses.


The Porro prism provides crisp, sharp, and bright vistas.

Because of the ergonomic design, it is easy to use.

Because the lens is multi-coated, it is more protective.

It is long-lasting because it is fog-free and waterproof.

The best value for money


Cost of purchase

  • Vortex Optics Viper HD Roof Prism Binoculars 10×50

Some thought has been put into the features of this product. All of this works, by the way.

Right/left eye focus and strap attachment ran as intended. It’s a well-executed concept. A well-thought-out design ensures that the front and back covers are securely attached, while the right piece serves as a temporary grip for the device.

Because I shoot with Canon ‘L’ lenses, I can tell you that the optical performance is excellent.

When worn around your neck, the case will stay attached to the pair.

Excellent design the case can fall away as an emergent object is spotted… very clever. Slowly, but surely, I’m figuring out how the 3rd-party tripod mount connects to the binocs.

However, I doubt that a 10x50mm lens will be noticeably shaky. I’m already a fan of the extra oomph. Because it hangs from the binocs, the case is barely noticeable.

The front cap isn’t the best.

  • Fujinon Polaris 10×50 FMTR Porro Prism Binocular

For astronomical purposes, I purchased these and they’re fantastic. Even the most distant celestial objects can be seen thanks to the high level of light transmission.

As a result, I chose the 10 x 70 for sky observation, but it can also be used for short views of terrestrial and marine objects while on a tripod. We are your one-stop-shop for everything you need.

It is easy to use and provides crystal clear views with these binoculars. These “binos” are perfect for astronomy, and I couldn’t be happier with how well they work.

The lens covers on the front and back do their job well and are easy to use. These binoculars are heavy, but they’re well-built, and as a result, they’re very stable. With these binoculars, you can have the view tuned in to as sharp as it can be for you, even if I’m a fan of center-focused binoculars

  • Celestron Granite 10×50 Binocular, Black (71374)

There is a noticeable sweet spot in the picture, and the rest of the view is very soft surrounding that point. For the price, the glare control is adequate.

When reversing directions, the focuser wiggles noticeably. To achieve the desired level of concentration, a little fiddling is sometimes required.

Outstanding value for the money. Problem is, that two bought pairs (one-year-old) had problems with diaptors swinging out of alignment after a short period. Celestron has a reputation for making high-quality binoculars, so this seemed out of the ordinary to me.

Neither of the bins could be used in the field because their diaptors were not in sync, so I took them both to an optics shop for repair. Other people may be having the same issue with the same model.

I am hoping that the store will be able to fix the problem and prevent it from happening again in the future. Another issue with the Celestron design is that the front lens caps come off so easily that I’ve already lost one.

To avoid losing the front rubber caps of your Celestron bins in the first two miles of your hike, I strongly advise you to use super glue to secure them into their connection slot. The design of the connection points isn’t ideal.


It’s ideal for stargazing.

A tripod can be used to keep it steady while you watch.

It has everything you need for a better viewing experience.

There are two variants available.

ED glass lenses with a premium coating are included.

Fog and water-resistant making it ideal for outdoor use.

Twist Up eyecups allow it to be used with eyeglasses.


Poor for hunting.

The lens cap is poorly designed.

  • Celestron Echelon 10×70 Binoculars

I’m a big fan of high-quality optics, no matter if it’s for target rifles, spotting scopes, or astronomy. I have a lot of glass, and some of it is better than others, but based on my initial impressions, these are at the top of my collection.

I got them a couple of days ago and used them to see Comet 2014 Q2 Lovejoy last night. This set of binoculars performed admirably, despite the frigid conditions and the Gibbous Moon. Steiner 8X32 Military Marine Binoculars are the second set of hand-held optics I own.

They had a good view of the comet, but the quality was nowhere near what it should have been.

When I use the Steiners to look at street lights or headlights at night, they show a lot of blooming. The way they deal with stray light in the optical path is extremely annoying. Steiner Echelons, on the other hand, is far superior in this regard.

When compared to the Steiners, I noticed that stray light and blooming were significantly reduced, which led me to conclude that Steiners’ lower price point binos are not of the same quality as their higher-priced counterparts. In the service, I made use of.

The Echelons are built to last but aren’t so heavy that they’re difficult to handle. They appear to be made of aluminum rather than magnesium, which would explain their substantial weight. The black rubber over-molded rubber is firm and not spongy. ” They come in a foam-lined polycarbonate case.

It’s not quite Pelican level, but it’s still pretty good. The objective lens covers aren’t doing anything for me. However, they are a tight fit. A tad too snug, but they’re still attached to the lens.

Finally, I decided to take a closer look at the Moon, hoping that I could spot any color fringing from the comet’s tail. Despite this, the Moon’s brightness was so excruciating that I could barely see it. If you’re going to be looking at the Moon, a neutral density filter would come in handy.

Despite my lack of experience, I believe these binoculars are excellent. Great brightness and color accuracy with a flat field of view.

  • Eschenbach Arena D+ 10×50 B Binoculars.

An extremely handy pair of binoculars which I like very much as a spectacle wearer thanks the eyecups attached for this purpose.

The scope of delivery with a shoulder strap and front and rear eyepiece protection together with a bag are extremely useful.

The light intensity of the binoculars in dim light surprised me very positively, which is probably due to the balanced magnification and the 32 mm front lenses.

The color rendering is very good, the coating of the glasses does not show any negative effects on colors or loss of light for me.

Haven’t checked the water-resistance yet, the glass has only been used in dry or foggy weather so far.

The focusing via the central focusing wheel is sufficiently stiff and can therefore be adjusted precisely without running the risk of quickly changing something again.

The size of the glass is also practical, it fits comfortably in a backpack or a belt pouch; With the belt loop on the carrying bag, it can also be attached there without major hindrance when hiking or cycling.

All in all, a highly recommended lens for anyone who likes to make observations in nature.

  • Nikon 7245 Action 10×50 EX Extreme All-Terrain Binocular

These 10 by 50s take the place of a pair of Swift Kestrels that crashed after 17 years of service. In terms of construction, they are at least comparable. The water and fog resistance are especially welcome. These Niikons do not have a cheap feel.

They are clear and have little distortion. In addition, the inside anti-reflective design is excellent. Plastic cels and fittings appear to work just as well as the previous aluminum cels and fittings. They are well suited to both astronomy and ordinary use.

That is saying a lot when I compare them to the much more expensive Fujinon Polaris. The Fuji brand is well-known for marine binoculars, but they are rather bulky and cost four times as much as these Nikons.

The night sky is well illuminated. I can imagine these being useful for general use and carrying, even if I prefer my roof prism Pentax for its tiny size and lightweight.

A single pair of binoculars cannot do everything. Look no further for the price. They will last for a long time, and your eyes will thank you. Trust me on this.

Is 10X50 better than 7X50 or 12X50?

Binoculars 7X50

750 binoculars are excellent for general use and perform well in most conditions. If you want to go bird watching or hunting, you should have 1050 binoculars.

You will be able to focus on those little targets more effectively if you use a higher magnification.

Binoculars 10X50

The 10×50 is a touch heavier than the 750 on the higher side, but if you use a monopod, it will be easy and steady to use. M82 and M81, which are 13 million light-years apart, are hardly visible. 1050 are better for viewing huge objects such as the Pleiades, M31, Hyades, and the moon.

When we utilize 750 instead of 1050 to observe M33 or M31, we’ll state the 750 will show you even smaller distant objects.

Binoculars 12X50

Binoculars with a magnification of 1250 are ideal for stargazing and astronomy. However, keep in mind that higher magnification settings (often anything over 10x) will necessitate the use of a tripod.

High magnification will substantially accentuate the effects of your hand movements, making it difficult to focus on the target. A tripod can help to improve stability to a large amount.

Binoculars Price

As previously said, there are various varieties of binoculars on the market. The cost of a pair of binoculars rises with each addition of a feature. This means that you must consider particular pricing ranges when making your decision.


If you’re looking for a decent deal since money is an issue, this is an excellent category to check at. In this category, you’ll discover all of the essential features you’ll need, but nothing special. In this price range, you may buy a bino with eye relief ranging from 10mm to 18mm and an exit pupil ranging from 2.5mm to 5.3mm.


If you want something that you can use for sightseeing without breaking the bank, this is the greatest price range to consider. In this price range, you can find binoculars with both a roof prism and a Porro prism. Expect magnification ranging from 842 to 10x 50.


In the mid-range category, you’ll discover some binoculars that strike a good balance between functionality and price. In this range, different models will have different features available, and you must make an informed decision.

In this price range, you will have a good selection of magnification and lens diameter options. Expect a magnification of 1050 as well as numerous enhancements such as Eco-Glass, ED Glass, HighPoint design, and Dielectric coatings.

$500 to $1000

This is the price for such binoculars if you want the right kind of lens coating, such as anti-glare, as well as water and fog-resistance features.

$1000 or more

This price range is reserved for professionals. Every product on this page will be fully featured and made of high-quality materials. This category will include high-powered magnification, large-diameter lenses, phase reduction coatings, water and fog resistance, and other features.

Features To Look Out For In A binoculars

Of course, there are some more features to think about. These are function-based features that are only required if you intend to use your binoculars under specific settings.

Performance in low light

If you like to stargaze or hunt at night, low-light performance is always important. In this case, you’ll need a pair of binoculars with a huge diameter that can gather a lot of light even in low-light settings.

These binoculars can be used in cloudy settings, as well as during twilight and dawn. If you intend to use your binos for astronomy or stargazing, the lens diameter should be at least 50mm. 45mm is a wonderful choice for hunting or bird watching. You should select 42mm for general-purpose use.

Stabilization of images

If you have shaky hands, image stabilization is required. It’s a handy function to have if you’re on a boat and need to focus on an image. These binoculars are pricey because they use high-quality prisms to stabilize the views.

Night vision

Again, if you intend to use your binos in low-light settings, invest in night vision binoculars. These binoculars will contain optoelectronic lenses that generate images based on the amount of light that enters the lens. These lenses are extremely pricey.


Water and fog proofing are two uncommon features found on these binoculars. The insides of these binoculars are completely sealed off from the outside world by dust and salt spray. Some of the binoculars also came with dry inert gas packed inside the binoculars.

In any conditions, it will not produce any water vapors owing to condensation.

How do You Pick the Best 10X50 Binoculars?

As you have previously seen, some of the most crucial qualities that these 1050 binoculars have to offer. Let’s take a quick look at each of them again to make sure we’re on the same page.

The numbers linked with these binos are self-explanatory: the first one indicates magnification and the second indicates end diameter. There are a few other things to think about.

Prism shape

These binoculars employ two distinct types of prisms. The first is a Porro prism, and the second is a roof prism. The Porro prism is made up of two right-angled prisms that face each other and do not align the eyepiece with the objective lens.

The roof prism is made up of two prisms separated by a gap or two prisms joined in a V-shape. Porro is less lasting than roof prism, which is brighter but less clear.

If you are always on the go, choose roof prism because it is more robust. It is also an excellent choice for dark circumstances such as astronomy and stargazing. Porro, on the other hand, is superior in terms of lucidity. This is a superior option for bird watching and hunting.

Coating for lenses

Lens coatings come in a variety of styles. Coated, multi-coated, fully-coated, completely multi-coated, and phase-coated are examples of these. Fully coated (ideal for general purpose) lenses reduce light loss more than coated lenses.

Multi-coated lenses (ideal for hunting and birding) cover a wider range of wavelengths on the lens surface.

Fully multi-coated (best for boating) lenses reduce reflections and refraction across the entire wavelength spectrum. The gloominess of the images produced by the roof prisms is reduced by phase coating (best for astronomy).

Comfort for the eyes

This is the distance between the focal point and the center of your vision. If you wear glasses, the image will be focused behind the eye relief distance by your binoculars. Sharpness will be significantly improved. Eye relief of more than 16mm is required for spectacles wearers.

Materials It is preferable to use high-quality materials such as strong rubber, leather, metal, and silicon.

These materials are used in various combinations by different manufacturers. If you intend to use your binoculars outside. However, for a lot of movement, your binoculars must be impact resistant.

Viewing angle

It is the width of the view from one end to the other inside your binoculars, commonly given in meters or yards.

If the magnification is high and the objective is tiny, the field of view (FoV) will be wider. The recommended FoV for a 10×50 binocular is 6 to 8 degrees.
