Buyer Guide to Choose the Best Monoculars

As it happens with telescopes, even to choose the best Telescope for your needs, it is essential to evaluate a series of decidedly technical factors, which almost all depend on the use of the device: what use is it intended to do?


Many telescopes are on sale, produced by many famous companies in the sector. The brand is not essential, but it is still a factor that guarantees the quality of the appliance and the materials with which it is made.

Among the best brands, we find Celestron, Uscamel, and BNISE, which in addition to making quality products, provide customers with excellent assistance: a factor that should not be underestimated.


And it is precisely based on the type of use that you intend to make of the Telescope that can depend on the kind of optics to choose. Some models are suitable for observing birds and natural elements; others also integrate a night vision system, and so on.

For this, it is essential to check the number of magnifications and the diameter of the objective lenses, because precisely based on these factors, it depends on the brightness of the enlarged image and the amplitude of the field of view.

Recognizing these data is very simple: generally, after the product name, some digits are inserted (for example, 40 × 120), which represent precisely the number of magnifications and the diameter of the lenses in millimeters.

Lens Material

The material with which the lenses are made is one of the factors that determine its quality. Generally, the lenses of the telescopes are made of glass, but two types of glass are used on the market:

  • Bak7: the lenses in this category are made of borosilicate glass, a model particularly appreciated for its resistance and a high degree of transparency
  • Bak4: the lenses in this category are made using a Crown-barium glass, which stands out for its low refractive index and low light dispersion. It is the best type of glass for the production of telescopes, which makes it more expensive than the BAK7.

Generally defined with the term “coating,” the anti-reflective treatment that the lenses have received is another factor to be taken into consideration. On the market, you can find four different types of anti-glare treatment, which are characterized by features and price:

  • Coated (c): it is an anti-reflective coating layer applied only on the external surfaces and on the eyepieces;
  • Multi-Coated (mc): in this case, several layers of anti-reflective coating are applied to the outer surfaces of the lenses;
  • Fully Coated (Fc): the anti-reflective layer is used both to the external and internal surfaces and to the outer surfaces of the prisms;
  • Multi Fully Coated (MFC): it is the same process carried out with FC, but it is carried out with multiple layers.


That of focus is a determining factor for the use of the Telescope because it serves to make the displayed image as clear as possible.

Generally, the most common models use a classic wheel placed just before the eyepiece. Still, the best models are equipped with a focus wheel covered with a non-slip rubber surface, to improve and make focusing more comfortable.


Even though in eyepieces, the eyepiece is much simpler than that used in telescopes, before purchasing the model that best suits your needs, it is essential to evaluate the relief that distinguishes it, that is the part that comes into contact with the face.

It is an essential factor for a correct vision of the image and, generally, it should be made in a cover in comma to adhere in the best way to the eye.

Dimensions and Weight

Dimensions are another significant factor to evaluate because they significantly affect the practical use of the Telescope. And also, the choice of this factor depends on the type of application to be made of it.

On the market, you can find pocket riflescopes, small and not very heavy, or larger models much more inconvenient to carry.

Furthermore, especially if you intend to use the Telescope also freehand, weight is an aspect to be evaluated because if too crucial in movement, it could make it challenging to support the device with your hands.

Smartphone Adapter

Some of the more modern telescopes also integrate a particular adapter with which you can connect your smartphone and see what is framed directly on the device’s display.

It is a very comfortable accessory even if you want to use the mobile device to take photographs or record videos, but generally, not all fans are used to using.

The Telescope is a versatile tool, which allows us to observe nature, panoramas, concerts, and even matches. However, before purchasing this item, it would be essential to understand what the primary use that will be of it would be since each model is suitable for a different purpose.

To help you choose, and avoid doing the wrong shopping, we have written a small guide in which we will try to explain the most important features to consider.

The magnification that Is: How Close?

If you have already seen some spotting scopes, you may have also noticed a numerical value accompanied by an “x.” This information tells us how many times the framed subject is enlarged.\

Let’s take a quick example: a 20x value means that our subject will appear twenty times closer, so if we are observing something that is 40 meters away, it will seem only 2 meters away, or 40 divided by 20.

This parameter, of course, is to be taken into consideration when choosing a quality telescope because, with a high magnification factor, we also have more details. However, there are negative aspects, such as a reduced field of view, i.e., the portion of the image that the device manages to frame.

A small field of view may be unpleasant when you want to look at a panorama, but it will be suitable, for example, for the observation of an animal or when we want to follow the players on the field during a football game.

The choice, as mentioned, should be based on the use that we will mainly make of it, or you can opt for models with variable magnifications, which therefore have a sort of zoom.

The Target

To have a clear, clean, and bright image, attention must also be paid to the lens. Also, this component is accompanied by a value, generally (but not always) located on the right of the X.

It must be thought that the higher its diameter, the more light will reach the Telescope, with the advantage of a more accurate vision of the subjects located at a distance, even in those situations where there is low light.

The negative aspect is the more considerable bulk and the increase in the weight of the Telescope.

The inversion system As we have seen, the telescopes differ in magnification, size of the objective, and, consequently, weight. Still, the main difference lies in the inversion system, which divides the models into two groups: prism and roof prism.

The inversion system allows us to see the image straight because otherwise, it would be reversed (due to the optical system). In essence, the prisms contained in the instrument allow us to view the subject appropriately and also have a broader vision.

The more traditional models are called “prism” or colorful; they are cheaper and easier to use because they are based on a simple system of mirrors placed inside the binoculars structure.

Roof prism luminaires, on the other hand, have a more complex structure and cutting-edge technology, but also a higher cost. Furthermore, it must be said that they are more compact and resistant.


If you are thinking of purchasing this type of item to carry it around with you, perhaps during an excursion in the mountains, also keep in mind the weight and size.

Of course, a bigger lens is brighter, but if you need something more straightforward and faster to manage, aim for a model with small dimensions. Do you think that the weight can vary from about 100 grams to over 2 kg, a big difference?

The smaller ones are also more suitable for long observations because holding them in your hands for a long time will be more comfortable and less tiring.

Frequently Asked Questions

Who Invented the Spotting Scope?

To answer this question, unfortunately, it is necessary to dispel the myth that attributes the invention of the Telescope to the Italian physicist, astronomer, mathematician, philosopher, and academic Galileo Galilei.

Galileo, in fact, only rebuilt and empirically enhanced the original model of the Telescope, which would have been invented by a German-born Dutch eyeglass man: Hans Lippershey.

The conditional is a must also in the second case, however, as more detailed studies have shown that the authorship of the invention is not to be attributed even to Hans Lippershey since the latter would have learned the secrets of constructing the Telescope from a traveler arrived in his shop.

How to Build a Spotting Scope?

Building a telescope is relatively simple since only a couple of tubes of different diameters are needed, which can be plastic or rigid cardboard, a sheet of plywood from which to obtain the coupling sleeve between the eyepiece tube and the main tube, screws, and rings for assembly, a diaphragm, and lenses for the eyepiece and objective.

Except for the lenses, therefore, which can be purchased easily online or in an optical shop, all the rest of the material can be quickly recovered at a little cost or by recycling.

As for the correct measurements and assembly, however, just rely on one of the numerous technical guides, also in the form of video tutorials, which can be easily found on the net.

How Does a Spotting Scope Work?

The principle of operation of a telescope is based on its optical scheme, that is, on the type and number of lenses that compose it. In a telescope, the program is written of two lens systems: objective and ocular.

The objective is, in turn, composed of one or more converging lenses, which produce the real and inverted image of the observed object; the latter is formed on the posterior focal plane of the glass and is reduced by the convergence effect.

The eyepiece, on the other hand, in turn, composed of a diverging lens depending on the type of Telescope, captures the real, shrunken and inverted image produced by the objective, and returns it as a virtual image, enlarged and straightened by the effect of the divergence.

What Is the Best Rifle Scope for Shooting Range?

The riflescopes usually used in shooting ranges are those with an angled body; these devices are placed on a tripod, near the shooter, and are aimed in line with the target. The angled eyepiece, therefore, allows the shooter to access the eyepiece without being forced to bend over too much.

In their optical scheme, a roof prism is inserted in order to compensate for the angle of the main body, given the standard distances between the shooting platform and the target.

Moreover, and except for particular exceptions due to specific needs, models equipped with a lens between 60 and 80 mm in diameter are particularly recommended.

How to Turn a Telephoto Lens Into a Telescope?

If you own a telephoto lens for a digital camera that you no longer use, know that it is possible to recover it by transforming it into a spotting scope. Transformation is simple; using a specific photographic accessory called Telescope.

On the market, primarily online, you can find different models with specific attacks depending on the attachment of the lens; the most popular, of course, are those designed for EF Canon and AF Nikon mounts, therefore also suitable for compatible lenses produced by Tamron, Samyang, Sigma and other companies in the sector, and for microscopes equipped with T2 thread.
