Binoculars for Astronomy – Top Picks Guide for Beginners in (2021)

Charting the stars is a fun way to spend the evening if you have the right gear to do so. They can be pricey and heavy, even if you can get a telescope. Instead, to help you see the stars, you should opt for a decent pair of stargazing binoculars. They are built to allow you to see the sky more clearly and brightly and are easy to use and lightweight.

Binoculars for astronomy are a perfect alternative to telescopes. They serve the same function but provide a special viewing experience for you. Many experienced stargazers have a pair of binoculars to complement their primary viewing equipment at their disposal. These instruments allow you to comfortably locate celestial objects without having to cart bulky gear around.

The market has a lot of fantastic binoculars. Standard equipment built for wildlife, though, just won’t do it. Taking a closer look at the universe requires advanced gear that properly collects light and provides optimum magnification levels. That and more can be achieved with the latest astronomy binoculars.

Why Use Binoculars for Astronomy?

You might wonder why, in the first place, some astronomy enthusiasts want to use binoculars. They can’t give you nearly as much viewing power as large telescopes, considering their compact size, right?

The fact is, not even the best binoculars on the market are as detailed as a heavy-duty telescope. That’s not, though, why individuals want to use them. You see, there is one thing binoculars offer that no telescope can offer.

There are significantly smaller binoculars than telescopes. Most can be thrown with a strap around your neck or tossed into a backpack. Compare that to the 20-plus pounds that a giant optical tube weighs, and for many astronomy enthusiasts, it is not difficult to see why binoculars are the go-to. For an impromptu trip to a low-light zone, you can easily take out binoculars.No need to pack up a huge piece of equipment or spend a lot of time setting up your viewing equipment. Just take out the binoculars, concentrate, and take a look.

In addition to portability, binoculars also give you a viewing experience that is more realistic. If you gaze through a telescope at the stars, you are looking at a tiny picture that has been mirrored and refracted. The field of view is small and to see the picture you need only one pupil.

A broader field of view that feels normal is offered by binoculars. More light is also gathered through the two optical barrels, creating a better image. Plus, you use both eyes, making it feel like you’re in front of your target right there.

What makes a good pair of Binoculars for Astronomy?

You will only be able to do so with a pair of high-quality binoculars, whether you want to see stars, planets, or far distant nebulae. As we discussed earlier, when you want to look up at the night sky, bird watching gear is not going to serve you well. Keep the following things in mind during your search to ensure your fresh binoculars are fit for your needs.

Magnifying Power

The first thing people look at when they’re looking for binoculars is always magnification. It’s not the only thing you should remember, although it is critical. It is not necessarily going to make a big difference to have a higher magnifying force. With 10X magnification, most individuals can do just fine. To take a look at the moon and see star clusters up close, is more than enough.

The majority of celestial objects you can see through binoculars will be very large. Thus, a lower degree of magnification will give you a wide field of view that you can fully appreciate.

With that said, if your purpose is to look at long-distance objects, you can go higher. The magnification of 20X is perfect for viewing Jupiter’s rings or the Orion nebula. Usually, in the first number of binocular specifications, magnification strength is represented. Take, for instance, 10 or 50 binoculars. The 10 indicates that there is 10x magnification in the gear.

Type of Prism Used

The justification for binoculars being so small is that they use prisms. Basically, complicated glass components that control light are prisms. They will increase the light path between the lenses and the eyepiece without having to adjust the size of the optical tube, essentially increasing magnification.

For astronomy, there are two different types of prisms that will fit well. These involve a prism of Porro and a Prism of the Roof. The prisms of Porro are the most available. They are also known for creating sharp, better-contrast images. This prism strategically concentrates light to make sure you get a clear picture that is highly visible.

Roof prisms are terrific, too. Since it helps the gear to be smaller and more secure from the weather, high-end binoculars use roof prisms. Using a roof prism, you will also find waterproof binoculars. Although modern roof prisms are not as powerful at focusing light, they can reduce light loss to create brighter images than ever before.

Width and Aperture of Objective Lenses

The opening of a pair of binoculars, including telescopes and cameras, specifically influences how much light falls in. A larger aperture means that you get a bright picture with a lot of color and contrast.

The same goes for the objective lens size. Larger lenses make it possible for the optical cones to fill with light, contributing to improved image quality. The lens diameter is measured in millimeters and can be found in the second set of binocular specifications. The 50 means that the objective lenses are 50mm in diameter from our earlier example of 10-50 binoculars.

Eye Relief

The distance between the central image and the binocular eyepiece’s final lens is eye relief. This is especially significant for wearers of eyeglasses. Eyeglass wearers ought to get binoculars with long eye relief, so you can’t really get closer to the lens. Alternatively, customizable eye cups often work wonders.

Build Quality

First, let’s talk about the efficiency of the building. Outdoors, binoculars are intended to be used. So, you’re not going to have a hard time locating machinery that’s made of tough materials. Stick to thick treated glass and high-quality metals. Your binoculars should be sturdy enough to keep even unintended drops in place.

Finding equipment that’s dustproof, waterproof, and shockproof is always good. Except in the most rugged conditions, these kinds of binoculars are specially treated to keep the internal optics intact.

Overall Size

It’s important to consider the scale, finally. There is a delicate balance between optical equipment range that is wide enough to allow a lot of light in and small enough to take on the go. They do have their merits with large binoculars. With better picture quality and higher magnification, they also come. But, to use them safely, you would need to use a tripod adapter.

When portability is your focus, lightweight binoculars are perfect. While they are not as powerful as large devices, they have the added advantage of being lightweight and simple to use.

These binoculars feature an extra-wide field of view, and to provide a clear image, the 50-mm objective lenses capture plenty of light. It features a durable aluminum housing as well.

Its low magnification is the downside to these binoculars. To see many of the smaller objects in the night sky, the 7X zoom provided by the binoculars is not enough. We found them perfect for looking at the moon but were unable to see the moons of Jupiter.

These are great for those who want the best binoculars for astronomy and are not afraid to pay a few additional bucks to get them. Featuring 25X magnification, these strong binoculars allow you to see deeper into space and pick up smaller objects than you would with most of the others on this list. The 100-mm objective lenses are the largest on this list and will add a lot of light to help show a bright picture with a lot of contrast. To make it easier to get your eye in a place to see the picture, it also features a 15-mm eye relief. In order to use the binoculars when wearing glasses, the rubber around the oculars often folds back.

Unfortunately, these binoculars are very expensive and, at over 10 pounds, are also the heaviest on this list. Using the provided tripod connector, you may need to install these on a tripod to use them properly. There is also no mobile phone connection available, which we would have liked this strong and this costly on binoculars.

Check Price on Amazon

Another large pair of astronomy binoculars on this list is the Celestron 71009 SkyMaster Giant Binoculars, and these feature oversized 70-mm multicoated objective lenses. Glare and false images are minimized by the multicoated objective lenses, while the large lenses gather more light and create a brighter and clearer image.

A tripod mount is also included in the Skymaster astronomy binoculars. We suggest using the tripod mount for the binoculars because they are bulky at almost four pounds, and fatigue can set in easily when using them in a handheld fashion. The neck brace that is included is very flimsy, thin, and awkward. We also feel that while these binoculars offer a vivid, clear picture, several objects in the night sky will not be brought out by the low 15X zoom.


  • 70-mm objective lens
  • Multicoated optics
  • Tripod adapter


  • Heavy
  • Thin neck strap
  • Low magnification

Buyer’s Guide on Binoculars for Astronomy

Let’s look at what features a set of astronomy binoculars should include.

Major Components

The critical components of astronomy binoculars are these next few things, and we suggest paying additional attention to these things.


One of the most significant features is the amount of magnification a pair of binoculars gives when using them for stargazing. You would need at least 15X magnification to see the moons of Jupiter or the rings of Saturn, and even that can render seeing these objects a challenge. Anything beyond that may only be helpful for gazing at the moon or constellations.

Objective Lenses

Another important feature of the astronomical binocular is the objective lens. The lens farthest from the eye is the objective lens. Light is collected by this lens. The larger this lens is, the brighter it will be for your image. It will improve your field of view as well.

Since we are going to use these binoculars in the dark, having the largest objective lens you can find is important. For stargazing, we suggest an objective lens not smaller than 50-mm.



The last major component of astronomical binoculars is the weight. Some stargazing binoculars have enormous objective lenses that can cause the binoculars to weigh up to ten pounds. This weight can settle right on your eyes as you look up at the stars and it can easily become painful.

We strongly recommend ensuring that it has a tripod attachment if the binoculars you are looking at weighing over two pounds.

Minor Components

Minor elements are important but not crucial. If one or two of these components are not available for a pair of astronomy binoculars, they might still be fantastic.

Weather Resistance

In rain or snow, we rarely look at stars, but it’s usually dark. Accidents occur, and whether they slip into a puddle or on the wet or snowy ground, water resistance may be beneficial.


As with water resistance, our delicate astronomy binoculars are not likely to be abused, but accidents do happen. We recommend that you never buy binoculars that look cheap and flimsy or feel cheap. For enhanced grip and durability, some astronomy binoculars can give a rubber coating, which is a nice feature.

Eye relief

In order to see a good picture, eye relief refers to how close your eyes need to be to the lens. With higher magnification devices like telescopes and spotting scopes, eye relief is a more critical problem since the image delivered to the eye is much smaller. However, it is important to consider using binoculars, particularly if you are wearing glasses. We suggest aiming for at least 12 mm of eye relief, but the higher the amount, the more comfortable they will be to use.

Multicoated Optics

Multicoated optics apply to applied coatings that help them minimize glare, provide a clearer picture, and decrease fogging. Multicoated lenses appear on binoculars of higher quality, so keep that in mind when you shop
