Some technical

Before getting into the thick of things, there are some small technical points that need to be understood to understand how one must choose his binoculars . When seeking binoculars, you realize immediately that there is encrypted information, such as:

7×50 Binoculars
10×50 Binoculars
20×80 Binoculars
25×100 Binoculars
… Etc …

7×50, 10×50, 20×80 … But what is it ?? In reality, it is very simple. That’s what happens in clearer language:

For example, 7×50 binoculars are twin whose magnification factor (or approximation) is 7 , and the diameter of the targets (one for each eye) is 50 mm . Ah! It’s still easier just say it like that, right? šŸ˜‰

So the 7×50 binoculars magnify 7 times, this means that if you observe an object at 100 meters you will see in binoculars as if he was at 14 meters, ie 7 times closer (100 / 7 = 14).

To even simpler, take binoculars 10×50 … If you see your neighbor or your neighbor who is a hundred meters away you will see in binoculars as if he or she was at ten meters (one hundred divided by ten, or ten multiplied by percent).
If the object is located 1 km you will see it as if it was at 100 meters from you. In fact when you see binoculars, just understand that the first number is multiplied by the distance of objects to be observed in relation to you, or divide the distance to the object by the magnification.

– Oh yeah cool, then I just have to choose binoculars with a magnification super, so I can watch whatever I want, no matter the distance!
In fact, it’s not as simple: the higher the magnification, the more a quake effect will be felt, because of the distance of the object, which will become very difficult to observe a moving object because the field of view is so very small. It will therefore make the choice of compromise …


The diameter

The second number after x is, we have said above, the lens diameter , expressed in millimeters. This diameter is important: the higher it is, and the field of view is great, and the more light collection. And therefore most objects are visible.

– Ah well there , I just have to take binoculars with a medium magnification and a diameter?

Not so fast! Their diameter has great advantages, but we must also consider the size of your binoculars . The smaller the diameter is high and more the binoculars will be imposing, both in weight and in volume . So again you will need to make a reasonable compromise between what you want to watch and the size of your binoculars.

You certainly start to understand that to properly choose his binoculars, it depends on the use that we will make it, because there are a lot of very different things that can be seen with binoculars:

Astronomy – binoculars list here
theater – binoculars list here
hiking – binoculars list here
hunting – binoculars list here
the boat – binoculars list here

Since we are an astronomy site , we focusĀ our buying guide binoculars in this area. Nevertheless, this manual may be great for anyone wanting to buy binoculars , because their characteristics are the same, only the use is different. For nature lovers, this is a binocular of choice: the Bushnell Legend Ultra HD 10×42 , which are very popular. You can also view my selection of 10 binoculars for hiking .

To summarize a bit our study of magnification and diameter , we must remember that the higher the magnification, the more there is light (more the object is visible) and the image is stable and pleasant to watch.
More the magnification is high, more the observed object is near, but the image becomes less stable, the field of view is reduced. As for the diameter, the higher it is, the more cumbersome the binoculars, but the image is comfortable to watch.

Go a little summary in table form:

High magnification (10x, 12x, 15x) Low magnification (6x, 7x, 8x)
Excellent reconciliation reconciliation means
Jitter Good image stability
Less Brightness good brightness
Field of vision restricted Large field of vision


Large diameter (50x more) Small diameter (less than 50x)
Very bright picture little light image
cumbersome compact


The exit pupil (also known by its initials PS, or eye circle)

The exit pupil is the bright spot that can be seen when looking in binoculars from a distance, that is to say when they are not glued on eyes.

The exit pupil is actually the diameter of the image of the objective, expressed in millimeters. If you want to know the size of the PS of a pair of binoculars, you can simply do this:

diameter lens / magnification = PS
PS This is related to the size of the pupil of your own eye. So for 10×50 binoculars, the PS is 5 mm (50/10).

The exit pupil is different depending on your age:

Age Exit pupil
Child About 8 mm
Less than 50 years About 6 mm
Over 50 years About 4 mm

The type of construction

There are two types of construction in the manufacture of binoculars:

  • The Porro prism
  • The roof prism

The Porro prism is assembling the most common in the manufacture of binoculars. We easily recognize this type of binoculars apart by their very goals. This type of construction is very strong and gives the images observed a very good brightness.

The binoculars roof prisms are more expensive! They have a newer technology than Porro prisms, their great interest is that they are tighter, more compact and lighter.

Astronomical observation

The technical details being acquired, let’s get serious, namely the choice of binoculars for observing the skyĀ !
When you feel attracted to the sky and the stars, we often think the telescope for observation of the moon, planets and nebulae and other galaxies. The telescope is the preferred device for any amateur astronomer who respects and yet …

The pair of binoculars is the perfect companion for the beginner astronomer! Indeed, this instrument is much less bulky than a telescope, you can take it anywhere, and remove at any opportunity! Binoculars are really a tool of choice for beginners in the observation of the sky. Additionally, binoculars can also serve as day toĀ observe nature , which is an important asset.

Most amateur astronomers will tell you, even if they have the latest telescope to fashion , they hide somewhere necessarily a good pair of binoculars, because they are a very good complement to the telescope.

– Okay so yes I want to do astronomy with binoculars, but I do not know which to choose?

You should know that the most popular models are the 10×50 binoculars, which are usually a very good price / quality ratio .

However, the more you go up in the range, and you will get results interressants with 10×60 binoculars or 15×70.

If you are highly motivated, you can get into stargazing with 25×100 binoculars … But then given the size of the instrument, you really want to!

Generally, when the twins are greater than 10×50 binoculars, it is better to buy a good tripod to avoid wear some heavy instrument and comfortable way to enjoy power celestial objects. For example, if you buy a pair of 20×80 binoculars , you can absolutely surprising observations, but you will have to acquire a good tripod bonus …

In any case remember this: for a beginner who wants to start observing astronomy, I can not advise you anything other than a good pair of 10×50 , which even if it is less heavy than 10×60 , it will really help to make quite exciting debut without having to invest in a tripod.

The price of binoculars

Obviously the more expensive instrument, the better its quality . This is a principle which does not apply at all, but about good binoculars, the price is still much difference. It is very difficult to give a starting price or a minimum price as binoculars, there are in all price ranges. But to remain reasonable, let’s say your budget is OK as long as you do not exceed $ 300. Beyond $ 300 is that you can afford to spend on your passion!

What telescope for a child?

I regularly receive messages that parents ask me what telescope they can provide for their child. It is true that in this jungle, it is not necessarily easy to find the appropriate equipment for your child …
That is why I decided to write this article about choosing a telescope for child , and I hope you will find it helpful.

A telescope or scope?

When you ask what telescope you can buy for your child, if you do not know much in astronomy equipment, there is a good chance that you are not asked this question:

Should I give my child a telescope, or rather a scope?

Yet this is the main question for you , since both devices are not completely identical, although sometimes a scope is also called “Telescope.”
But we’ll see that it’s very easy to tell the difference.

TheĀ Scope

The scopeĀ is a device composed of sets of mirrors thatĀ  reflect light . His other nickname, the reflector. It is usually this kind of instrument that the pros use in astronomy because it is able to collect a lot of light and render beautiful pictures.
However these appliances also has its drawbacks:

  • He’s heavy
  • It takes up space
  • It is quite difficult to solve: it must be collimated, that is to say align its mirrors.
  • It is expensive
  • It requires maintenance

In short, I do not really recommend this type of scopeĀ “reflector” for a child under age 14, unless you plan yourself you begin exploring the sky: you can show your best results to your child.

I think this kind of telescope may well suit a beginner, but for a child who wants to take his first steps in astronomy , at least to begin with, I do not think this is the ideal equipment, or thinking that’re used alone.

The astronomical telescope

The astronomy telescope does not use the same technology: it is an instrument composed of lenses thatĀ refract light . It is also called “Refractor telescope”, or “refracting telescope”. If you want to know more about the different types of telescopes, I refer you to my article dedicated to this subject:

The advantages of the seat in relation to the telescope are:

  • It is lighter
  • It is less cumbersome
  • It does not require settings
  • It costs less
  • It does not require maintenance
  • It is stronger
  • It is easier to use

You’ll understand if you ask me what you need to buy as telescope for your child (4 to 14 years), I would say thatyou should buy her a telescope rather than a telescope , unless you have the intention to initiate your own child to astronomy: in the latter case, it may be wiser to choose a good telescope, which will allow you to observe many deep sky objects.

What can you see with a telescope?

The moon

Many people wonder what they’ll do with a telescope or a telescope. The telescope astronomy is the tool of choice to watch the wonderful crater of the Moon.Ā 

It was quickly amazed by the beauty of the seas of the moon, and the exceptional level of detail offered a telescope. In short, for a child, see the moon in style with a bezel is already doing the most surprising of discoveries!

The planets

The bezel also allows to enjoy Saturn and its rings, or the planet Venus . But do not lose sight that you see these tiny planets (except the Moon) in the goal of your telescope. And we need your child being aware: do not believe that he will immediately see Saturn as well as on all images that one can find on the internet. This does not least a stunning show! See Saturn in true, it’s like making a real dream!
A window allows to see the monster gaseous Jupiter and huge bands and his big red spot and its four satellites.

The sun

Attention danger : The telescope is a precision instrument able to harvest light exponentially, it would be catastrophic for your child to point the camera toward the sun . This could blow his retina irreparably .
But it is possible when taking the proper precautions, observe his majesty the Sun, our star, and large fire plumes into space. For this, it will equip your telescope or telescope sunscreens. Indeed, there are filters to watch the sun safely.

The stars

There are hundreds of observable objects with a telescope. When we know that a telescope arrives to collect about 150 times more light than the human eye, you soon realize that it is possible to contemplate countless objects in the sky with nothing but a telescope!


The bezel, unlike the telescope, actually can observe terrestrial objects such as birds, trees, mountains, boats … This can be for your child being delicious discoveries.

The astronomy club

Your child wants you a telescope, fine … But how can you be sure it’s not a passing interest? There are a lot of astronomy associations bringing together enthusiasts ready to share their passion for the stars .
I advise you to take your child to a club or an astronomy association, and there it will really be a idea of what it represents.
it will also participate in astro nights that allow him to try a bunch of telescopes, which can only be beneficial for his discovery of thirst … and he will know better what it means stargazing.

Where to buy?

Avoid buying such equipment in supermarkets or in toy stores: I think that in 99% of the time, the equipment you will gain will be of such poor quality that your instrument will be only good for the rest back of a closet. It is better to prefer a specialty shop in this material to avoid disappointment .

I also advise you to buy your products online at AmazonĀ because they offer an impressive range of products for very attractive prices.

Our selection of glasses

Here is a small selection of glasses which should be appropriate for your child. Remember, what we call bezeldenominates also telescope . The glasses have a narrow tube that telescopes. In the table below, the instruments are presented glasses except 130/900 skywatcher which is a conventional telescope (reflector).

Through this small article, I tried to help you see more clearly in your telescope purchase process for a child. Although the acquisition of a good telescope (eg 130/900 Skywatcher , which is among the best selling telescopes at Amazon) may well be a good choice, the advice I prefer to give parents in general, rather it is to move towards a telescope.

I also advise you to buy a good book on astronomy and flick it with your child, you will soon see if for him it is an area that really interests. If you have a good pair of binoculars , you can also begin his initiation of the sky in this way, especially pointing the moon, which is already very interesting to look through binoculars.
