Monocular Buying Guide
Selecting the best monocular might not be as simple as it seems. Luckily, and with a little help from this guide, you should soon be observing the night sky with your brand new monocular.
Night vision, magnification, the field of view, and lens are only some of the features to consider when searching for the best monocular. Not sure what these terms mean? Don’t be afraid—in order for you to pick a good monocular for stargazing, I’ll explain these specifications—and more.
Different Types of Monoculars
The best monoculars come in three different optical designs: Galilean, Porro and roof prisms.
They’re built-in with simpler lenses and are best for close range. They’re not, however, the greatest choice for stargazing.
Porro prisms were the standard optical design up to the 1960s, before roof prisms were introduced. They’re distinctive by their zigzag shape and tend to provide better light contrast. Although they’re considered obsolete, they produce at least the same quality image as roof prism optical design monoculars.
Porro prisms can be made of two different types of glasses. High-density glasses are called BaK-4 and are able to gather more light from the lens periphery. The second type, BK-7 glasses, are made of crown glass and have shaded edges. They’re less expensive but of lower quality.
Roof prisms have a straight shape and can easily be held, even by a child’s small hand. Inside the lens, the light follows a more complicated path requiring a more precise optical design. This makes the manufacturing process complex and therefore more expensive.
The best monoculars are made with roof prisms, which is why they’re recommended for stargazing.
How Do I Choose a Good Monocular?
With many options available, what are the other features to look for in monocular?
As we mentioned earlier, the lens size is displayed directly on the monocular. A 10×25 monocular features a lens size of 25 millimeters.
Lenses often range from 20 to 50 millimeters—monoculars are always referred to using the metric system. Generally speaking, the bigger the lens, the wider the view will be.
A bigger lens allows more light to enter and will generally produce brighter images, ideal for stargazing.
Of course, larger lenses come with a slightly bigger footprint and these monoculars tend to look bulkier.
Field of View
The field of view—also referred to as FOV—represents the width of the image. You guessed it, as the monocular FOV increases, the magnification decreases. The best monoculars can, however, provide both an acceptable FOV with good magnification.
When it comes to stargazing, it’s a matter of personal preference. Some stargazers may enjoy strong magnification, to zoom in on specific stars or planets. Others prefer a wider aperture to have a broader view of the night sky.
Although regular monoculars can be used for stargazing, the night vision monoculars feature an IR illuminator providing more light in complete darkness. Their magnification is typically lower, and because they use batteries, their design is heavier and bulkier.
They tend to be sturdier and provide a clearer—although green—image. Originally used by the military, night vision monoculars come at a higher price point, too.
Most night vision monoculars shouldn’t be used during daylight as it can damage the lens. If you’re looking for a day & night or multi-purpose monocular, it might be best to select a traditional one.
Looking for night time only monocular? Don’t mind a slightly heavier design? Then night vision monoculars will light-up the night sky to reveal thousands more stars.
Monoculars come with one of three different types of lens coating.
Simple lens coating is the most affordable, however, most hobbyists search for the fully coated lens.
Fully coated lenses can help reduce glare, but also improve the brightness and clarity of the image.
Multi-coated lenses are the high-end spectrum of coating technique and used to make the best monoculars. They provide a top-notch image quality but also come at a premium price.
A good coating doesn’t only increase the visibility, it can also discard water and fog.
The best monoculars’ lenses can be filled with inert gas, preventing water or dust from entering the lens. A good monocular for stargazing might also be shock and temperature proof, for better durability.
When water—even a small amount—or humidity finds its way inside the monocular, fogging and a poor quality image will result.
So, how can you determine the waterproof level of a monocular? On this feature, manufacturers have made it easy for us. The best monoculars should clearly indicate the IP waterproof rating, showing an IP followed by a number—such as IP68.
This rating is standard to measure how resistant to water a container is. The first number—six in this example—indicates the protection level against dust and can range from one to seven. The second number—eight—can range from one to nine and indicates the level of water resistance.
For either digit, the higher the better, IP ratings over 56 are recommended.
The eye relief is the distance between the lens and your eye and normally ranges from 10 to 20 millimeters. You might not think of eye relief as an important feature when searching for the best monocular. It is, however, worth considering for at least two reasons.
Eye relief has a big impact on how comfortable the monocular is. If the lens is too close or too far away, it will also impact the quality of the image.
If you’re wearing eyeglasses, it’s important to look for an eye relief of 15mm or over.
The best monoculars normally come with an adjustable focus to give the image optimum clarity.
It shouldn’t be considered an optional feature, and if the monocular doesn’t come with an adjustable focus, you should consider another one.
Plenty of options are available when it comes to design. Focus ring, knobs located inline, above, or below the monocular, the options are endless. For easy use, you might want to select a focus adjustable with one hand only.
What Is the Most Powerful Monocular?
Because monoculars are more compact than binoculars, many stargazers are under the impression that they’d be losing on performance. In reality, when comparing monocular power ratings, they offer the same power as binoculars, with half the size.
The power of a monocular is determined by its magnification. This is one of the most important factors to consider as it determines how much the device can enlarge the image you want to view.
Magnification often ranges between 2x and 25x. A 2x magnification power means that the targeted object will appear only two times closer than with the naked eye. Monocular magnification ratings can give you the first indication of your monocular’s capability.
You might have seen what looks like extra-large monoculars. Although they look like powerful monoculars, these devices belong to the family of spotting scopes.
They’re usually standing on the ground or on a tripod. While we’re not dealing with them in this guide, monocular scope reviews often highly rate them. They can be considered if you’re looking for a device stronger than a monocular but more compact than a telescope.
What Is the Best Magnification for a Monocular?
Are you looking to observe in detail, or the famous craters of the moon? Wanting a closer but wide view of the sky? Here are a few things to consider while selecting the best magnification for your monocular.
When looking at a monocular, you should find two numbers with a multiplication factor in between. For example 10×25. The first number indicates the power of the monocular, while the second number indicates the lens size.
A monocular with a magnification of 12x or over is considered extremely powerful, the image should be much clearer and detailed. As power increases, however, the field of view decreases, meaning that you’ll get a narrower sky view, potentially missing out on things like shooting stars.
Large magnification monoculars may be difficult to use, as the image can be unstable at high magnification. Using a tripod is recommended to get a clear image as this prevents the inevitable shake you will get when the monocular is handheld.
Finally, costs increase as the monocular’s power increases. Although this is still a debate, most would agree that a good monocular for stargazing should have a 7x or 8x magnification.
Monocular for Beginners
When starting out, it’s generally preferred to keep it simple. Not only will a modest monocular be easier to use and master, but it’ll also be much more affordable. Large power monoculars can empty your wallet faster than you can think.
Acquiring a monocular is an important step, however, if you don’t know what to look for in the sky, you might get quickly bored. You should be able to spot at least 2,500 stars just with your naked eyes.

Monocular for Kids
While you’ll find that most skywatching devices designed for children are mainly binoculars, a few monoculars options are also available.
When it comes to kids, playing is often one of the best ways to learn. What about a monocular that is fun and usable during day time as well? Starting out with a lower-price point monocular might be best. As your child’s interest matures, you can upgrade to a more sophisticated monocular.
Best Portable Monoculars
Size and weight matter when choosing the best compact monocular. Although the best monoculars are fairly small, an 8×25 or 10×25 monocular should be able to fit most pockets.
Small monoculars normally come with a compact case and are easy to transport to wherever the stars bring you.
Because of the smaller lens, performance and power are usually impacted. On the bright side, small monoculars are often the most affordable.
Monoculars for Astrophotography
Looking to capture the moon on your cell phone? Monoculars won’t disappoint you. Some of them come with an adaptor to attach your mobile to your monocular’s eyepiece.
Although pictures don’t come out perfect—a monocular’s lens being circular while the phone frame is rectangular—they make great souvenirs for friends and family. Instagram editing options will also help you add a finishing touch to the picture.
DSLR cameras would create too many vibrations with a monocular, resulting in a shaky image and picture. If you’re looking to take pictures with a DSLR camera, scopes would be better-suited than monoculars.
You’ll be able to purchase a special adaptor for digiscoping. Some scopes even come with a built-in camera to take pictures and movies.
Although binoculars seem more popular for stargazing, monoculars’ compact size makes them increasingly popular. While they can provide the same field of view and magnification as binoculars for stargazing, they only take up half of the space. This makes them the ideal device to carry on your travels.
Even with a narrower selection available, options are suitable to all levels, from kids to beginners and more experienced stargazers. While monocular ratings are important to consider, you’ll have to choose the one specifically suitable to your needs.
Because I always look for devices that can withstand time and use, my winner in this selection is the Bushnell Legend monocular. Sturdy and built with high-quality material, it provides specifications that can fit all users, from beginners to the most experienced.
