Stargazing is an exciting hobby that has gained popularity in recent years. Whether you are an experienced astronomer or just starting, choosing the right tool to assist you in your celestial observations is critical. 

Two common options for stargazers are telescopes and monoculars. 

The telescope is the ideal optical instrument for astronomers viewing deep-sky objects such as nebulae, planets, moons, and galaxies.  Monoculars are handheld devices that view far-distant objects with only one eye. However, the monocular has limited use in stargazing due to its smaller aperture size, low magnification, and shorter focal length.

In this blog post, we will discuss key differences between a telescope and a monocular, the benefits of each instrument, and when to choose any based on your intended use. We will also answer a few questions, including if you can observe the planets with a monocular.  

Is a monocular more suitable than a telescope?

The choice between a monocular and a telescope will depend on your intended use and experience with stargazing. Monoculars are typically smaller, lighter, and more portable than telescopes, making them a good choice for those who want a lightweight, easy-to-carry tool for observing far-distant objects. 

For example, if you love watching birds, hunting, or scouting, a monocular is a much better choice than a telescope. On the other hand, telescopes generally provide a clearer and more detailed view of the night sky.

Monoculars can be designed to have exclusive features, including a built-in compass, zoom power monoculars, rangefinder, and even night vision monoculars.

However, if you are serious about stargazing or astronomy, you might want to go all in and purchase a telescope. A good telescope will give you the best view of celestial objects like planets, stars, and the moon in as much detail as possible.

What are the benefits of using a monocular?

There are many benefits of using a monocular. However, its usefulness will depend on your specific needs and preferences. Here are some benefits of using a monocular:

Portable and lightweight

Monoculars are small and lightweight, making them easy to carry around and use on the go. This makes them ideal for people who love engaging in outdoor activities like hiking, camping, traveling, and stargazing.

Easy to use 

Monoculars are typically more user-friendly than telescopes and don’t require any special setup or assembly. They are also easier to focus on and can be used with one hand, making them a fine choice if you want a more straightforward tool. 

In addition, some people may find that using a monocular is more comfortable for their eyes, as it only involves the use of one eye. This can be particularly helpful for people with vision problems in one eye or those who find it challenging to use both eyes together.

Lower cost and more affordable

Monoculars are typically less expensive than telescopes, making them a good choice for those new to stargazing or on a budget. They offer an excellent introduction to the hobby without making a significant investment.

When to choose a monocular?

A monocular can be a great choice in several different situations, including:

For casual and recreational stargazing

Monoculars can be a convenient and cost-effective choice for casual and recreational stargazing. They are compact, lightweight, and easy to carry, making them ideal for stargazing on the go. 

When choosing a monocular for casual and recreational stargazing, it’s essential to consider the magnification power. A magnification power of 7x to 15x is generally sufficient for casual stargazing, allowing you to see details in the night sky while still being able to hold the monocular steady. Anything smaller is better suited to wildlife spotting.

In addition to magnification power, the objective lens size is also essential. A larger objective lens will gather more light, resulting in a brighter image. For casual stargazing, a monocular with an objective lens size between 40-50mm is recommended.

A top-notch monocular that fits is the Opticron Explorer WA ED-R 8×42. This monocular has 8x magnification power and an objective lens of  42mm, making it a perfect choice for casual stargazing.

What are the benefits of using a telescope?

A telescope is an instrument used to view distant objects by gathering and focusing light. It offers many of the same benefits as monoculars, but they also have some unique advantages. With that said, here are some benefits of using a telescope:

Increased magnification and image clarity

Telescopes have a much higher magnification power than monoculars, which enables you to see objects in the sky in much greater detail. Hence, they are ideal for viewing distant stars, galaxies, and celestial objects.

Also, most telescopes feature high-quality optics, such as lenses or mirrors, that can produce a more explicit and sharper image than you would get with a monocular. This makes it easier to see fine details in the night sky, such as the rings of Saturn or the craters on the moon.

An excellent example of such a telescope is the Celestron Inspire 100AZ Refractor. This telescope is designed to be simple and smart for new astronomers of all ages.

Key differences between telescope and monocular

Telescopes and monoculars are great tools that can magnify distant objects, but they have distinct differences that make them suitable for different types of stargazing. Let’s look at the main differences between telescopes and monoculars:

Magnification and image quality

Telescopes typically have much higher magnification power than monoculars. Hence, you can see objects in the night sky in greater detail with a telescope. However, it’s important to remember that higher magnification does not always equal better image quality. The quality of the image is also affected by the aperture size, lens quality, and other factors.

Aperture and light-gathering ability

The most significant difference between telescopes and monoculars is the aperture size. The aperture is the diameter of the lens or mirror that gathers light and directly affects the amount of light that can be collected. Telescopes typically have larger apertures, allowing them to gather more light, which makes it easier to see faint objects in the night sky.

On the other hand, Monoculars generally have smaller apertures, limiting the amount of light they can gather, making it more difficult to see faint objects.

When buying an instrument for stargazing, it’s essential to consider the aperture size. The larger the aperture, the more light the telescope can gather, and the brighter and clearer the image will be. 

For advanced astronomical research, we recommend a telescope with an aperture of at least 8 inches.

Get the Celestron NexStar Evolution 9.25 on Amazon.

A good telescope that fits is the Celestron NexStar Evolution 9.25. It is a standout telescope with its single-fork arm and rechargeable lithium-ion battery that allows for 10 hours of continuous use with the touch of a button.

Portability and ease of use

Telescopes are generally larger, require additional equipment, and are more difficult to transport than monoculars. While this can be a drawback for some stargazers, it also allows telescopes to have larger apertures and higher magnification power.  On the other hand, monoculars are more compact and portable, making them an excellent option for those who like to stargaze while on the go.

Can a telescope serve as a monocular?

Many telescopes can be used as a monocular by removing one of the eyepieces. This is especially useful for stargazers who want the magnification power of a telescope but the portability and ease of use of a monocular. 

However, it’s important to remember that using a telescope as a monocular will limit the amount of light that can be gathered, as the aperture size of the telescope will be halved. This can result in a dimmer image, especially when observing faint objects in the night sky.

Can you observe the planets with a monocular? 

You can observe the planets with a monocular. The planets are relatively bright objects in the night sky and can be seen even with a small aperture monocular. 

However, the level of detail you will be able to see will depend on several factors, including the magnification power of the monocular, the quality of the lens, and the aperture size. With a high-quality monocular, you should be able to see the craters on the moon, planets such as Jupiter and Mars, comets, and star clusters. If you have a good monocular, you can spot Saturn’s rings, the Galilean moons, galaxies, and nebulae.

However, a telescope with a larger aperture and higher magnification power is typically necessary for more detailed observations.

Takeaway: Grab the best optical instrument for optimal stargazing

It is exciting to note that monoculars and telescopes are excellent tools for observing far-distant objects. The choice between them will depend on your specific needs and preferences. 

As mentioned, a monocular is a single-piece optical device and offers some unique benefits, such as portability, affordability, and ease of use. You can enjoy stunning views beyond stargazing, including birdwatching, wildlife observation, and sporting events. This makes them a more versatile tool to have. However, it lacks the features required for detailed deep-space object observation.

If you’re looking for a more immersive stargazing experience with the ability to see faint objects in greater detail, a telescope may be the right choice. But a monocular may be a better choice if you’re looking for a more compact and portable option. Regardless of your choice, getting out there and enjoying the night sky is important!
