The magnification that your lens will give is equal to the ratio of the focal length of the lens to the focal length of the eyepiece. Two 0.5 diopter lenses give a focal length of one meter. If the focal length of the eyepiece is 4 centimeters, the telescope will give a magnification of 25 times. This is quite enough to observe the Moon, the satellites of Jupiter, the Pleiades, the Andromeda nebula and many others interesting objects night sky.

Useful advice

Do not try to select lenses with a focal length of 1-2 centimeters for the eyepiece. The image produced by such a telescope will be greatly distorted.

Telescope made from spectacle glasses

A spyglass is an ancient item that allows you to observe distant objects. However, this optical device, which was used back in the era of the Great Geographical Discoveries, has not lost its popularity to this day. You can make a spyglass with your own hands, and not only for games or historical reconstruction. This terrestrial observation instrument should produce an upright image, not an inverted one.

You will need

- 2 lenses;
- thick paper (whatman paper or other);
- epoxy resin or nitrocellulose glue;
- black matte paint (for example, auto enamel);
- wooden block;
- polyethylene;
- scotch;
- scissors, ruler, pencils, brushes.

Instructions

On a wooden cylindrical blank, the diameter of which is equal to the negative lens, wrap 1 layer of plastic film and secure it with tape. You can take a regular shopping bag. Wrap paper over the film pipe, carefully coating each layer with glue. The pipe length should be 126 mm. Its outer diameter is equal to the diameter of the objective lens (positive). Remove pipe from the blank and let dry.

When the glue has dried and the pipe has hardened, wrap it in one layer of plastic film and secure it with tape. Exactly the same as in the previous step, wrap pipe paper on glue so that the wall thickness is 3-4 mm. The length of the outer pipe is also 126 mm. Remove the outer piece from the inner piece and let dry.

Remove the polyethylene. Insert inner pipe to the outside. The smaller part should move more inside with some friction. If there is no friction, increase the outside diameter of the smaller pipe using one or more layers of thinner. Disconnect the pipes. Paint the interior surfaces matte black. Dry the parts.

For the eyepiece, glue 2 identical paper rings. This can be done on the same wooden block. The outer diameter of the rings is equal to the inner diameter of the small pipe. The wall thickness is about 2 mm and the height is approximately 3 mm. Paint the rings black. They can be made immediately from black paper.

Assemble the eyepiece in the following sequence. Inner surface Apply glue to two centimeters of a small pipe at one end. Insert the first one, then the small lens. Place the second ring. Avoid getting glue on the lens.

While the eyepiece is on, make the lens. Make 2 more paper rings. Their outer diameter should be equal to the diameter of the large lens. Take a sheet of thin cardboard. Cut a circle out of it with a diameter equal to the diameter of the lens. Make a round hole with a diameter of 2.5-3 cm inside the circle. Glue the circle to the end of one of the rings. Also paint these rings black. Assemble the lens in the same way as you assembled the eyepiece. The only difference is that first pipe a ring is inserted with a circle glued to it, which should face the inside of the pipe. The hole acts as a diaphragm. Place the lens and second ring. Let the structure dry.

Insert the ocular elbow into the objective one. Select a distant object. Point pipe for sharpness, moving and spreading the tubes.

Please note

There is no need to make a device of high magnification, otherwise the pipe will be inconvenient to use by hand.

Useful advice

The pipe can be painted with white paint, silver or bronze. Disassemble the device before painting. The eyepiece part can be left as is.

You can equip the telescope with a hood to cut off excess side rays.

You can use a high-quality long lens from an old camera.

The sight of the starry sky can make few people indifferent. But it’s even more pleasant to observe the Moon and other celestial bodies through a telescope. It is quite possible to make a simple telescope yourself; all you need is desire, a little free time and the most simple tools and materials.

Instructions

Cut a strip of paper 5 cm wide and 50 cm long from a sheet of whatman paper. Paint it on one side with black ink. Wrap the strip around the lens and secure it with glue. To ensure that the lenses are positioned evenly and not when using the telescope, fix them on both sides with whatman rings inserted into glue and fit tightly into the lens.

Before inserting the external fixator

We all know that with the help of binoculars you can see quite distant objects that are impossible to see with ordinary by the human eye. If you are already tired of watching animals, people or cars and you have long been harboring a dream of seeing the moon or the starry sky, then this article is for you. Today we will tell you how to make a telescope from binoculars.

Making a telescope

The main function of any optical device is an increase. To achieve good magnification, we need the simplest binoculars. The theater one is very suitable for this purpose. Due to its small magnification, we can achieve magnification in the telescope up to 20-30 times. Of course, if you choose a more powerful binocular model, then the magnification will be greater, but I don’t see the point in this, since it is very high magnification does not give a very clear picture.

In order to assemble a telescope, we need only one eyepiece, since, as we know, a telescope is observed with only one eye. Of course, we will also need a second eyepiece, but if we unscrew it from the binoculars, then the device will accordingly become unsuitable for use in the area for which it was originally intended. If you don’t want to spoil such a wonderful binocular, you can buy a separate eyepiece, the magnification of which is no more than 8x.

So, we take an additional eyepiece and install it so that it is a few centimeters opposite the binocular eyepiece. The distance between them should be selected “by eye” by pointing at some object. During adjustment, you should cover the interocular space with something dense and dark, such as thick paper or newspaper. This is done so that the light does not disturb you.

You have already measured the distance, let’s move on to making the telescope tube itself. To make it, it is best to take whatman paper or any other thick paper. We also need a plastic or wooden tube of the appropriate diameter. Now we take the paper and wrap it around our rod, coating each layer well with glue. Make sure the edges are even. As soon as the glue dries, we insert our eyepieces into it, and the additional one should be installed so that when moving along the pipe there is a slight friction to focus.

Important: The greater the distance between the eyepieces, the greater the magnification and the worse the image quality. Therefore, be careful if you do not want your telescope to produce strong power.

Our binocular telescope is ready for use for its intended purpose. Just never point it at the sun, otherwise a fairly severe burn to the retina is possible, which can lead to blindness.

Advantages of the telescope

You will never be able to buy such a telescope in an online store or in a store. retail. Therefore, having made such a telescope for yourself, it automatically becomes exclusive of its kind.

A new telescope is very expensive. Therefore, it’s easier to buy inexpensive binoculars and do everything yourself.

From now on, you will be able to observe the night sky, and the number of stars will quite surprise you, since there are much more of them than when we look at the sky on an ordinary evening.

The moon will appear before you in all its glory. Now you can see its surface and relief.

That's not all the benefits homemade telescope. The rest you can discover for yourself when you start using it.

You can change some details at your own discretion. In this case, ingenuity and imagination are important. We hope that our tips helped you create your next masterpiece.

How to make binoculars?

Of course, the homemade design of this device will not be able to compete with industrial designs, especially professional ones. But you can try to make binoculars with your own hands, especially since it is not so difficult.

How to assemble it and what main parts it consists of will be discussed in our article.

Design

Before making binoculars, you need to carefully study its design. What parts does it consist of? Let's see!

It is assembled from two completely identical parts, connected along the width of the distance between a person’s eyes (adjustment is possible). Each part is a cylindrical tube. It has a pair of lenses mounted on each side.

Operating principle

Rays of light from a point distant in space on the front lens (objective) are refracted. And then they go to the back lens, which is called the eyepiece. From there the rays pass into the human eye. In this case, the object in question is magnified multiple times.

How to make a body

We will make the cylinders from thick cardboard by gluing (two identical ones). It should be taken into account that eyepieces, as a rule, smaller in size than the main lenses. Therefore, in the cylinder the circle where we insert the eyepiece should be smaller. This can be achieved by using an adapter made of plastic bottle, For example. The cylinders inside and out should be painted black or any dark color.

About lenses

Lenses, of course, can also be made by yourself. But it will be much easier to take ready-made ones (now sold separately or “picked” from magnifying glasses). Remember that the lens must be mutually convex and the eyepiece must be mutually concave. If this principle is not followed, the images in the binoculars will turn out upside down. We secure the lenses with tape, insulating tape or glue.

We connect the cylinders to each other with ready-made clamps or clips cut from a beer can. We adjust the distance between the cylinders and fix it in the desired position. This homemade binocular is ready for use. You can also try to involve your child in the manufacture of the device, as this is a fascinating and interesting process, designed for results and accuracy.

It's safe to say that everyone has dreamed of taking a closer look at the stars. You can use binoculars or a spotting scope to admire the bright night sky, but you are unlikely to be able to see anything in detail with these devices. Here you will need more serious equipment - a telescope. To have such a miracle of optical technology at home, you need to pay a large sum, which not all lovers of beauty can afford. But don't despair. You can make a telescope with your own hands, and for this, no matter how absurd it may sound, you don’t have to be a great astronomer and designer. If only there was a desire and an irresistible craving for the unknown.

Why should you try making a telescope?

We can definitely say that astronomy is a very complex science. And it requires a lot of effort from the person doing it. A situation may occur that you purchase an expensive telescope, and the science of the Universe will disappoint you, or you simply realize that this is not your thing at all.

In order to figure out what’s what, it’s enough to make a telescope for an amateur. Observing the sky through such a device will allow you to see many times more than through binoculars, and you will also be able to figure out whether this activity is interesting to you. If you are passionate about studying the night sky, then, of course, you cannot do without a professional apparatus.

What can you see with a homemade telescope?

Descriptions of how to make a telescope can be found in many textbooks and books. Such a device will allow you to clearly see the lunar craters. With it you can see Jupiter and even make out its four main satellites. The rings of Saturn, familiar to us from the pages of textbooks, can also be seen using a telescope made by ourselves. In addition, many more celestial bodies can be seen with your own eyes, for example, Venus, large number stars, clusters, nebulae.

A little about the telescope design

The main parts of our unit are its lens and eyepiece. With the help of the first part, the light emitted by celestial bodies is collected. How distant bodies can be seen, as well as what the magnification of the device will be, depends on the diameter of the lens. The second member of the tandem, the eyepiece, is designed to enlarge the resulting image so that our eye can admire the beauty of the stars.

Now about the two most common types of optical devices - refractors and reflectors. The first type has a lens made of a lens system, and the second has a mirror lens. Lenses for a telescope, unlike a reflector mirror, can be found quite easily in specialized stores. Buying a mirror for a reflector will not be cheap, but self-production will be impossible for many. Therefore, as has already become clear, we will be assembling a refractor, and not a reflecting telescope. Let's finish the theoretical excursion with the concept of telescope magnification. It is equal to the ratio of the focal lengths of the lens and eyepiece.

How to make a telescope? We select materials

In order to start assembling the device, you need to stock up on a 1-diopter lens or its blank. By the way, such a lens will have a focal length of one meter. The diameter of the blanks will be about seventy millimeters. It should also be noted that it is better not to choose spectacle lenses for a telescope, since they generally have a concave-convex shape and are poorly suited for a telescope, although if you have them on hand, you can use them. It is recommended to use long-focal lenses with a biconvex shape.

As an eyepiece, you can take a regular magnifying glass with a thirty-millimeter diameter. If it is possible to get an eyepiece from the microscope, then it is certainly worth taking advantage of. It is also perfect for a telescope.

What should we make the housing for our future optical assistant from? Two pipes of different diameters made of cardboard or thick paper are perfect. One (the shorter one) will be inserted into the second, with a larger diameter and longer. A pipe with a smaller diameter should be made twenty centimeters long - this will ultimately be the eyepiece unit, and it is recommended to make the main one a meter long. If you don’t have the necessary blanks at hand, it doesn’t matter, the body can be made from an unnecessary roll of wallpaper. To do this, the wallpaper is wound in several layers to create the required thickness and rigidity and glued. How to make the diameter of the inner tube depends on what kind of lens we use.

Telescope stand

Very important point in creating your own telescope - preparing a special stand for it. Without it, it will be almost impossible to use it. There is an option to install the telescope on a camera tripod, which is equipped with a moving head, as well as fasteners that will allow you to fix different positions of the body.

Telescope assembly

The lens for the lens is fixed in a small tube with its convex outward. It is recommended to fasten it using a frame, which is a ring similar in diameter to the lens itself. Directly behind the lens, further along the pipe, it is necessary to equip a diaphragm in the form of a disk with a thirty-millimeter hole exactly in the middle. The purpose of the aperture is to eliminate image distortion caused by the use of a single lens. Also, installing it will affect the reduction of light that the lens receives. The telescope lens itself is mounted near the main tube.

Naturally, the eyepiece assembly cannot do without the eyepiece itself. First you need to prepare fastenings for it. They are made in the form of a cardboard cylinder and are similar in diameter to an eyepiece. The fastening is installed inside the pipe using two disks. They are the same diameter as the cylinder and have holes in the middle.

Setting up the device at home

The image must be focused using the distance from the lens to the eyepiece. To do this, the eyepiece assembly moves in the main tube. Since the pipes must be well pressed together, the required position will be securely fixed. It is convenient to perform the tuning process on large bright bodies, for example, the Moon; a neighboring house will also work. When assembling, it is very important to ensure that the lens and eyepiece are parallel and their centers are on the same straight line.

Another way to make a telescope with your own hands is to change the size of the aperture. By varying its diameter, you can achieve the optimal picture. Using optical lenses of 0.6 diopters, which have a focal length of approximately two meters, you can increase the aperture and make the zoom much closer on our telescope, but you should understand that the body will also increase.

Watch out - Sun!

By the standards of the Universe, our Sun is far from the most bright star. However, for us it is very important source life. Naturally, having a telescope at their disposal, many will want to take a closer look at it. But you need to know that this is very dangerous. After all sunlight, passing through the ones we built optical systems, can focus to such an extent that it will be able to burn through even thick paper. What can we say about the delicate retina of our eyes?

Therefore, you need to remember very important rule: you cannot look at the Sun through zooming devices, especially a home telescope, without special means protection. Such means are considered to be light filters and a method of projecting an image onto a screen.

What if you couldn’t assemble a telescope with your own hands, but you really want to look at the stars?

If suddenly, for some reason, assembling a homemade telescope is impossible, then do not despair. You can find a telescope in a store for a reasonable price. The question immediately arises: “Where are they sold?” Such equipment can be found in specialized astro-device stores. If there is nothing like this in your city, then you should visit a photographic equipment store or find another store that sells telescopes.

If you are lucky - there is a specialized store in your city, and even with professional consultants, then this is the place for you. Before going, it is recommended to look at an overview of telescopes. First, you will understand the characteristics of optical devices. Secondly, it will be more difficult to deceive you and slip you a low-quality product. Then you will definitely not be disappointed in your purchase.

A few words about buying a telescope through the World Wide Web. This type of shopping is becoming very popular nowadays, and it is possible that you will use it. It’s very convenient: you look for the device you need, and then order it. However, you may come across the following nuisance: after a long selection, it may turn out that the product is no longer in stock. Much more unpleasant problem- This is the delivery of goods. It is no secret that a telescope is a very fragile thing, so only fragments can be delivered to you.

It is possible to purchase a telescope by hand. This option will allow you to save a lot of money, but you should be well prepared so as not to buy a broken item. A good place to find a potential seller is astronomer forums.

Price per telescope

Let's look at some price categories:

About five thousand rubles. Such a device will correspond to the characteristics of a telescope made with your own hands at home.

Up to ten thousand rubles. This device will certainly be more suitable for high-quality observation of the night sky. The mechanical part of the body and equipment will be quite poor, and you may have to spend money on some spare parts: eyepieces, filters, etc.

From twenty to one hundred thousand rubles. This category includes professional and semi-professional telescopes. Surely a beginner will have no need for a mirror camera with an astronomical cost. This is simply, as they say, a waste of money.

Conclusion

As a result, we met important information about how to make a simple telescope with your own hands, and some nuances of buying a new device for observing the stars. In addition to the method that we have considered, there are others, but this is a topic for another article. Whether you've built a telescope at home or purchased a new one, astronomy will take you into the unknown and provide experiences you've never experienced before.
