At this low price point, you can’t expect all of the features and components seen in higher-end models. Celestron – Cometron 7×50 Binoculars are really a good choice for the new astronomers. It has many specifications that you can expect from any good-quality binoculars.

Its optics are not fully multi-coated, despite the fact that they are multi-coated. This suggests that the anti-reflection material has most likely just been applied to the lens surfaces. This is nice, but they will not have the same level of optical transmittance as those whose entire optical pathway has been treated. As a result, the image created will be of reduced quality and brightness.

These binoculars use the BK-7 prism glass which is not a good quality prism, whereas higher-end binoculars will use better prism glass. The eye-relief is adequate at 13mm; but, if you wear glasses while using your binoculars, they are certainly not the best option.

This is a far less expensive option as compared to the top-notch Echelon range and the Skymaster series, costing from $35 to $90 / £45 to £60.

Our Verdict

I would not suggest this Celestron Cometron binocular for marine use because it is neither water nor fog proof. Also, if you want to take them camping and use them for general purposes like birding, they might not be the best choice. They will be alright if you keep them at home or in a secure location away from the rain and dust.

“Couldn’t be happier! I have wide spaced eyes and have found it very hard to find binocs that I’m able to look with both eyes. These work wonderfully! Also, the build quality is super. They feel really good in your hands and come with lens caps and an excellent case. 10x magnification is more than adequate. They are compact, but not overly so. For the money, you can’t go wrong.”

“I have lots of binoculars, even some alpha’s. These are amazing for astronomy! Even if you live in a light polluted area (I live 50 miles away from New York City). They outperform some of my 10×50’s when looking at the Milky Way. These are also my son’s favorite out of all of our binoculars. Only downside is that they are slightly heavy and the focus wheel is stiff. Other then that these are built for a lifetime of enjoyment. You can get these binoculars and be done.”

Buyer’s Guide

Binoculars are significantly more complicated than the majority of people believe. They’re high-tech optical instruments with finely crafted lenses and painstaking engineering. Buying astronomy binoculars is difficult if you are unfamiliar with the technical lingo.

Furthermore, not all binoculars will be suitable for astronomy. The trick is to select a model that includes the capabilities you’ll need to view the stars clearly. Here are a few things to keep in mind as you navigate the market.

Magnification Power

Magnification power is one of the first characteristics to consider. Binoculars are designed to magnify an image multiple times so you can get a better view of celestial things in the night sky.

Zoom binoculars have a lot of power. Some models have the ability to magnify an image a hundred times!

To appreciate the cosmos, you don’t need high magnification binoculars. A magnification of 7X will suffice. The first number in a binocular’s description refers to its magnification level. So, in the case of 750 binoculars, the number 7 is the one to actually listen to. It signifies that the binoculars have a magnification of 7X in this scenario.

Measurements of Aperture

The aperture is a critical component in optical equipment because it determines how much light gets in. The opening of a camera is the area that admits light to generate an image on the focus plane. Binoculars’ aperture follows the same principles.

Binoculars bend light effectively by using many lenses. The objective lens is the binocular’s last lens, located at the distal end. This is where the opening specifications become important. The aperture of binoculars corresponds to the diameter of the objective lenses.

Try to choose the wider aperture. In low-light situations, they can produce substantially superior outcomes. The objective lenses of the 750 binoculars are 50mm and it is always the most recommended figure.

Focus and Clarity

Next, think about the many types of concentrating features that are available to you. Binoculars are made up of a number of complicated components that have been fine-tuned to produce a high-quality image. Everyone’s eyes, however, are different. There’s a considerable probability you’ll have to tweak things to get rid of blur and optical distortions. So go for the lens that has more clarity and focus.

The Lenses’ Quality

Binoculars used to have simple glass lenses. While they completed the task, they did not provide the best level of clarity. There are numerous elements that can sabotage the image. Everything from reflections to chromatic aberration will distort what might otherwise be a crisp image.

Fortunately, optics has come a long way! Many modern binoculars feature high-quality lenses that alleviate common sight difficulties.

They’re ideal for marine binoculars since they have a fog-proof coating that allows for crystal-clear vision.

Multi-coated lenses are common in more modern binoculars. The lenses may prevent undesired reflection and other kinds of light refraction depending on the particular treatment. Choose this option for the most clarity.

Field of View

The magnification power of the binocular and the diameter of its focal length are directly proportional to its field of view. It’s usually expressed in degrees, but yards or feet are also acceptable.

It’s always best to have a large field of view. This is particularly true when viewing a faraway object such as the moon or stars. A larger field guarantees that enough light is captured to produce a clean image. It also allows you to see more of the object you’re interested in.

Exit Pupil

The size of your exit pupil is another crucial component that influences what you perceive. The exit pupil is the small opening via which light escapes the binoculars and enters your eye. Light has traveled trillions of miles to enter into your binoculars and find its way to the exit hole when you’re looking at stars and other celestial bodies.

The diameter of the objective lens and the magnification level, just like the field of view, define

the maximum exit pupil size. With some easy math, you can determine the size of the exit pupil. Simply multiply the magnification factor by the aperture size. An exit pupil width of roughly 7.1 millimeters is typical for 750 binoculars.


Binoculars are often made of durable materials. To keep all of those priceless lenses intact, they must be highly durable and tough.

Anyone planning to buy binoculars should invest in waterproof optical gear. Birdwatchers, maritime laborers, and astronomers are among those who fall into this category.

A rubber coating is another characteristic that can help you save money. The optical device is protected by rubber armor. Second, the armor protects the one from getting shocks.


A few accessories might help you get the most out of your superb pair of binoculars. While not essential, these add-ons items can make a significant difference. A neck strap should be the first item you purchase.

When you’re not staring into space, you could use a strap to receive some hand relaxation. It also provides an additional layer of protection. The strap will catch your binoculars if you drop them unintentionally, protecting them from damage.

Frequently Asked Questions

Is it necessary to have a specific focus length?
The focal length is a measurement of how much light is diverged by the binoculars. Light is gathered through the objective lens when you gaze up at the stars. The light diverges on a single point inside the binoculars, called the focal plane, to magnify the vision.

The magnification level is directly affected by the focal length. The magnification power increases as the focal length lengthens. The field of view, however, is reduced. So we can say that the specific focal length is very important.
What field of view is best for Conventional Binoculars?
The binocular field of view is frequently expressed in terms of degrees or physical dimensions. The field of view is 6.5 to 7 degrees for most conventional binoculars.

A field of view of 300 to 400 feet for 1,000 yards is quite good in terms of physical metrics. When staring at a target from 1,000 yards away, this means you can see a breadth of 300 to 400 feet.


Universe is fascinating in any case, whether you look into it through binoculars or not. But using 7×50 binoculars to observe the galaxy allows you to get a close-up and personal glimpse of those secrets.

Man has been enthralled by what exists beyond our globe since the beginning of time. You now have access to cutting-edge technology that previous generations could even imagine.
