Is a monocular better than a telescope? Which is Better

Telescopes and monoculars are excellent tools for seeing distant things. We’ll take a quick look at each of these instruments to see what differentiates them and if you should purchase a tiny telescope or a monocular.

Monoculars appear to be a tiny refractor telescope at first glance. Where the light enters from one end and the enlarged picture appears on the other. But that’s where the resemblances end.

Monoculars are a cross between a telescope and a monocular. They’re significantly smaller than the tiny telescope on the market, and they don’t require any setup.

It features a single eyepiece, just like a telescope, yet it’s held in your hands like a monocular. You take it out of your luggage and start using it right immediately.


Is a monocular better than a telescope?

Monoculars are a type of modified telescope that zooms in on faraway objects by using a succession of lenses and, in some cases, prisms. It is much smaller than a telescope and much more compact than a pair of monoculars.

It’s easy to carry because of the basic design; some of them may even fit in the palm of your hands.

That’s why they’re great for hiking and hunting expeditions when you don’t want to be bogged down by gear. Furthermore, a monocular is relatively affordable and may be obtained for as little as a few dollars.

Simple, inexpensive monoculars feature only two lenses. Still, high-end monoculars have a prism between the lenses that folds up the rays to reduce the length of the monoculars while increasing magnification.

You’ll come across two main types of astronomy monoculars: roof and Porro. These names know the prism pattern within the barrels.

The off-set objective lenses to the eyepieces distinguish a Porro prism monocular — the eyepieces are closer together, and the objective lenses are farther away.

Roof prism objective lenses appear to be aligned with their matching eyepieces in a straight line. Monocular optical designs have advantages and disadvantages.

Each optical design uses glass, reflections, and mirror coatings to create its unique optical route.

Isn’t it similar to a telescope? Right! You can get a magnified picture of an astronomical object, similar to what a telescope can do, that the naked eye can’t see.

Types of monocular

  • Galilean Zoom Monocular
  • Night Vision Monocualr
  • Compass Monocular
  • Infrared monocular



Unlike monoculars, which have two barrels for monocular vision, a telescope only has one tube for monocular vision.

While there are many different telescopes and variations within those types, refracting and reflecting telescopes are the most popular.

Reflectors employ mirrors, whereas refractors use glass lenses. Other telescopes, such as catadioptric telescopes, combine lenses and mirrors.

Each has a unique optical path that has advantages and disadvantages for astronomical viewing and imaging.

Telescopes are great for magnifying a view so that celestial objects like the moon, planets, stars, galaxies, nebulae, and more may be seen.

What field of astronomy a telescope excels in is mainly determined by the size of critical optical components.

A telescope with a slow optical speed, for example, is ideal for planetary observation. A wide-field telescope may be an excellent optical instrument for taking a closer look at massive constellations, galaxies, and other objects.

Types of Telescopes

  • Refractor Telescope
  • Reflector Telescope
  • Catadioptric Telescope

Monocular VS Telescope


A standard monocular comes with zoom ranging from 4x to 10x. Higher zoom settings are now feasible. However, this will have a significant impact on image quality.

The range of view will shrink, and due to the scope’s tiny aperture, less light will reach the scope, resulting in a dull image.

Higher magnification capabilities will necessitate the use of a tripod to keep the image steady. Professionals avoid monoculars with higher zoom settings for these reasons.

A monocular with an 8x zoom is considered standard. This is when the telescope comes into play. A telescope is typically employed in situations requiring magnifications greater than 30x.

This is a better alternative if you want to look at distant things like a mountain top or celestial bodies like the moon.

A telescope’s larger aperture allows it to capture more light from distant objects, resulting in a brighter image.

Set-up Process

Monoculars, as previously stated, are utilized in run-and-gun situations and need little to no setup.

On the other hand, Telescopes are more prominent, bulkier, and need a significant amount of additional equipment and settings.

A slight hand movement or vibration might cause a fuzzy image because of their narrow field of vision. They require a steady tripod at all times.

A telescope is also made up of various components, such as eyepieces, which require appropriate adjustment and calibration.

A monocular, unlike a telescope, is a self-contained unit with no separate components. They have a zoom knob that is generally located near the eyepiece and a focus adjustment that is simple to set up.


One thing that irritates me is the suggestion that if you can’t afford a telescope, you should purchase monoculars.

Monoculars may be smaller, but much like telescopes, the larger they are, the better the quality and the higher the price.

Some of the most modest Monoculars with good optics can cost more than telescopes in the entry-level market, sometimes even three or four times as much.

As a result, comparing the two costs only based on “magnitude” isn’t a fair comparison.

Monoculars are valued for their optical components, features, and accessory compatibility in the same way as telescopes are valued for their optical components, features, and mount.

Can monoculars, on the other hand, be as expensive as high-end telescopes? Absolutely. Like night vision, infrared vision, and other capabilities, other technology can push the price to $10,000.

Sure, those items aren’t necessary for astronomy, but they give you a sense of how expensive optics can be. As a result, in terms of price, the telescope is the clear winner.


The diameter of the objective lens in a monocular and the primary light-gathering objective lens or mirror in a telescope is measured in millimeters.

They all have the same goal in mind: to capture light and aid in the formation of a magnified picture.

When you see two digits separated by an “X” in the model name or specs of monoculars, that’s the aperture. For instance, 1042. The second number identifies the aperture.

It might be listed in millimeters or inches in the model’s name of a telescope. For example, Celestron NexStar 6SE – the “6” denotes a 6” aperture on the NexStar telescope.

Monoculars, on the other hand, have narrower apertures than telescopes. The aperture of astronomical Monoculars should be between 42 mm and 100 mm.

At existing high price points that might be difficult to use, 42 mm should be the minimum, and 100 mm should be the maximum.

If you have a steady hand and are skilled, 50 mm is an excellent all-purpose size that may be utilized hand-held. Otherwise, for stable visibility, they should be attached to a field tripod.

Telescopes exist in various diameters, ranging from 50 mm to 16″ and beyond. As a result, they can “collect” more light than Monoculars and may be used to obtain considerably greater magnification than monoculars.

As a result, in terms of aperture, the telescope is the apparent winner.


A focusing mechanism is found in both Monoculars and telescopes. The focusing mechanism of a monocular is generally a central knob or wheel.

One of the eyepieces also contains a diopter that may be adjusted to fit your vision.

Even though many individuals do not know how to focus their telescope correctly, it is not difficult to construct the monocular.

The focuser may focus at either a single or dual speed, allowing for the course or coarse and fine focusing.

A focuser is also found on a telescope. Focusers come in various sizes, with the 1.25″ rack-and-pinion and 2″ Crayford being the most popular among amateur scopes.

When you focus the telescope, you’re pushing the focuser’s drawtube in and out of the telescope tube.

Each type of focuser and its variations has its own set of advantages and disadvantages.

Once you’ve determined your diopter, focusing on a monocular is straightforward and may frequently be done with only one finger. You can easily change the focus of your camera.

This causes the eyepiece to be adjusted up or down to give you the best image possible. Telescopes have a higher learning curve because there are more moving components and

numerous things that may go wrong depending on the type of focusers, such as backlash, slop, picture shift, and more. As a result, monocular is the apparent victor in terms of focus.


Monoculars, on the other hand, are smaller than telescopes. The greater the aperture, similar to telescopes, the larger and heavier the scope grows – and the price follows suit. In comparison to a 16X70, 1042 will be significantly smaller and lighter.

Size counts if you’re carrying your Monoculars on a harness or lanyard around your neck. Models in the 42 mm and 50 mm sizes are lighter than ever before, ranging from 21 oz to 35 oz. Yes, there are ounces. Because Monoculars are so light, this is the usual measurement unit.,

Some of the more sophisticated versions might weigh several pounds or more. The easiest way to use them is to mount them on a tripod.

The use of heavy Monoculars in hand might result in improper monocular use, wrist discomfort, and an inability to steady your vision. Mount it if it’s significant.

Small refractors and tabletop reflectors can be pretty light, weighing less than 10 pounds or perhaps less than 5 pounds.

They’re made to be portable and easy to travel with. Larger versions, weighing between 20 and 40 pounds, are nevertheless deemed suitable for travel.

Although telescopes are considerably heavier than monoculars, you benefit from not holding the telescope because the mount and tripod or base do it for you.

However, you must still move, put up, and deconstruct it. Monoculars are ideal for travel and on-the-go viewing. As a result, monocular is the apparent winner in terms of portability.


Reflectors have exposed optics and open tubes, and telescopes are delicate. Wind and rain are not an excellent combination. The majority of telescopes lack any waterproofing.

Monoculars, on the other hand, are the polar opposite of monoculars. They’re pretty durable, and the glass components are securely fastened. They can withstand a decent amount of abuse and continue to work typically.

If they aren’t entirely waterproof, most Monoculars are intended to be water-resistant at the very least. Unlike a telescope, they’re also built to withstand significant temperature fluctuations.

When a monocular is designed to be waterproof, the optical barrels are frequently purged with a gas, such as Nitrogen or Argon, to offer fog-proof protection.

This isn’t the fog you see on a cool morning; it’s the interior fogging of the optical chamber caused by temperature fluctuations.

Optical coatings are usually a basic need for good monoculars. As a result, most Monoculars will have optical coatings that telescopes may only begin to see around their mid-price ranges.

External lens coatings on Monoculars protect the objective lens from dust, rain, smudges, grease, and other contaminants.

These coatings can also repel them. As a result, monocular is the apparent winner in terms of weatherproofing.

Dual -Purpose Use

Prisms are integrated into the optical design of monoculars. Astronomical Monoculars are dual-purpose instruments with these prisms.

They may be used to stargaze and then quickly switched to land viewing. Hunting, sporting groups at the shooting range, monitoring and security, touring, animal observation, and much more may all be done with the same pair of Monoculars that you use to see the stars.

Not all telescopes are designed for terrestrial usage or viewing from the ground. Refractors can be used with a prism that acts as a diagonal to give the picture proper orientation.

With these optics, you’ll need a long focal length eyepiece to achieve low magnification and the broadest field of vision possible because they’re so powerful.

A monocular/spotting scope hybrid may be a good compromise if you can’t decide between Monoculars and spotting scopes.

In comparison to telescopes, Monoculars already include prisms and are built for close-focus distances with large fields of vision. As a result, monocular is the apparent victor in terms of Dual-Purpose Use.

What can you see while using Monoculars for Astronomy?

Although telescopes are the obvious choice for astronomy for various reasons, you may still stargaze without one.

They offer an immediate and accessible platform for observing celestial objects. Even with a tripod, it’s faster and easier to set up. They give considerably greater visibility than the naked eye and can be used for other things.

You can attempt to see an extensive list of different items. The monoculars’ specifications will determine the ability to resolve some of the more difficult ones.

Although many objects look colorless and featureless patches in the sky, some telescopes can’t do much better.

Rather than leaving the Monoculars at home, bring them along and use their large field of view to locate objects and get a good look.

Then, with your telescope, focus on it. It’s considerably faster to accomplish this using your finder scope first, then your telescope to study the scene in great detail.

You’ll be relieved to find that the abilities you’re acquiring with your Monoculars are the same ones you’ll need to operate a telescope.

Because telescopes come with motor drives that enable automated slewing to the object you wish to observe, star-hopping and using charts and maps may be more difficult with a monocular.

Moon: It is simple to locate and explore. Shadows, oceans, mountain ranges, and craters, as well as phases, eclipses, and the Terminator line.

Planets: Mars is one of the planets that may be recognized. Venus is visible, and its phases may be observed. Jupiter and its four moons may be seen.

Saturn shines brightly and is seen with Titan. It’s difficult enough to distinguish its rings, let alone divide them.

Deep-Sky Objects: Deeper objects, such as galaxies, can be seen, but only as “fuzzies.” With the appropriate galaxies, you’ll be able to point out neighboring stars that can assist you in finding some of Messier’s brightest objects.


Both! There is no time limit in this case. They each have their own set of advantages and disadvantages, and when the circumstance calls for it, they may complement each other.

If you wish to do astronomy, you should use a telescope to look up into the sky. They can bring planets up close to your eye, show you galaxies and nebulae, track stars, and much more.

If you already own a pair of monoculars, there’s no need to acquire more. Take it out and check how it functions.

Pull out the Monoculars if you don’t feel like putting up the telescope. If you want to scan the night sky, use your Monoculars first, then your telescope to zoom in.

If you add some flexibility and variety to your astronomical observations, you might be able to double your output in one night. Clear skies to you, whether you’re using a monocular or a telescope!


Q1 Is Watching a planet possible using a monocular?

A simple monocular has an aperture of only a few millimeters and has an 8x zooming capacity. You’d only be able to perceive the moon as a celestial body. You wouldn’t be able to get a close look at it either. Telescopes are good for seeing planets since they have a bigger aperture and magnifying power.

Q2 Can you attach a night vision monocular to a telescope?

You can, however not all monoculars are compatible. When you attach a monocular to a telescope, you risk overexposing the moon, turning everything green. In exchange, you will be able to view stars in infrared wavelengths that were previously invisible. The sky will appear more full and thick.


Is a monocular better than a telescope? The decision between a monocular and a telescope is based on your intended use and budget. If you’re planning a hiking vacation or a wildlife safari, you’ll need a portable, easy-to-use scope.

A monocular would be the best choice for situations when you grab a scope out of your pocket and take a look.

On the other hand, if you want to see mountain peaks, the moon, planets, stars, or anything exceptionally far away, a telescope is the appropriate tool for the job.
