Many people love to observe the sky, stars and planets, who can be not only professionals, but also amateurs or children developing their worldview. You can see the details of space using an optical device that you can buy to monitor the sky right from home. For this, a telescope is used, which is divided into several types. The article will help you learn the main types of devices, and will also determine how to choose a telescope for beginners, because there are many parameters and you need to pay attention to everything.
Operating principle and structure of the telescope
Structurally, the telescope is very complex, but with its help you can see the sky at multiple magnification. Visually, the device is made in the form of a tube, where on one side there is a lens for collecting light and/or a lens with a concave mirror. On the other side there is an eyepiece, with the help of which a person looks at the object and gets the desired picture.
To understand the device in more detail, you should consider the main elements in more detail:
- The pipe is the main element.
- The finder is a telescope that is greatly reduced and is necessary for the preliminary search for the desired picture.
- The eyepiece is a part of the device that can be replaced. For example, with a long focus, the magnification will be less, but increases visibility.
- Mount (mount) - often made in the form of a tripod, which includes a pair of rotary axes. Among the main types there are azimuthal and equatorial. The first helps to rotate the pipe in all 4 directions, and the second design is complex and large, but makes it possible to find objects in the sky at given coordinates and take photos.
- Light filters - can be used for many purposes, including dimming very bright light from the moon.
- Diagonal mirrors are an important detail that helps turn the picture upside down, since the image in the device itself is “upside down”.
Professional devices can take photos and videos, and are often supplemented with electronic equipment, a GPS module, and an electric motor.
Types of telescopes
To figure out how to choose a telescope for observing planets, you will need to study the main types. They determine the capabilities and scope of use.
Reflectors (mirror)
This model allows you to capture the light flux and transmit it to a person using a pair of concave mirrors. One of them is located in the telescope lens, and the second allows you to reflect the image at an angle and send it to the side eyepiece.
This optics is considered well suited for analysis and observation of deep space, and also helps to obtain clear and high-quality images of distant objects in the sky. The average cost when using an equatorial stand will be in the range of 14-55 thousand rubles. It is believed that this technique is not recommended for beginners and children, since it is very difficult to set up and operate the device.
Pros:
- A simple and understandable design for many.
- Small size and weight.
- Easily copes with objects that emit low light and are far away.
- A good aperture of 250-400 mm, which helps to see a bright and clear image without defects.
- Optimal cost when compared with similar refractors.
Minuses:
- Setting up the device will require a lot of time, and you also need experience working with the device.
- Since the structure is open, dust, dirt and water can penetrate into it.
- High sensitivity to temperature changes.
- The technology is not suitable for tracking terrestrial objects, as well as nearby bodies in our solar system.
Refractors (lens)
This type of telescope can be identified by its simple design, which is visually similar to a regular telescope. The eyepiece and lens are placed on the same axis, and the magnified image is transmitted in a straight line, similar to models that were in use hundreds of years ago.
Refractors are refracting optical devices that collect reflected light from objects in the sky using a lens. This element can be 2-5 biconvex and is installed on both sides of the pipe. This type of equipment is more suitable for beginners and amateurs, as it will help to see in detail ground objects, objects in the sky that are located in our solar system.
The lenses work in such a way that there is a partial loss of image clarity, so the image will be dimmer while viewing and working, especially if you use the maximum magnification. It is recommended to use such optics for open areas outside the city in order to completely prevent the sky from being illuminated.
Based on the type of lenses in the telescope, instruments can be divided into achromatic and apochromatic. The first options have a flat picture, but they have a low and medium magnification level. The second models will make the image convex, but allow you to remove defects, including unclear image boundaries and the formation of a secondary spectrum.
The average cost of a refractor using an azimuth mount will be in the range of 3,500-25,000 rubles. The price directly depends on the technical features, as well as the functionality of the equipment.
Pros:
- Easy to use due to the lack of special maintenance.
- The design is sealed, therefore it is reliably protected from penetration of moisture or dust into the housing.
- Not negatively affected by temperature fluctuations.
- Provides high clarity and contrast images of nearby bodies in the sky.
- Characterized by a long service life.
Minuses:
- Large dimensions and weight of the entire structure, in some cases it can reach up to 25 kg.
- The maximum lens diameter is 150 mm.
- The models are not suitable for viewing the sky within the city.
Catadioptrics (mirror lens)
The lens of such equipment is made on the basis of lenses and mirrors, due to which all the positive aspects of the models described above are collected in the device. In addition, the telescope makes it possible to eliminate defects as much as possible using specialized correction plates.
During human observation, video provides an almost perfect image of any objects in the sky, regardless of their distance. The telescope can be considered professional, in addition to this view, it is possible to take good photos. The cost of models with the ability to create photos starts from 10,000 rubles and ends at 3 million rubles. Professional catadioptric installations with optimal power will range from 18-95 thousand rubles.
Pros:
- Small sizes for easy transportation.
- Great for tracking bodies in space at any distance.
- This type allows you to get maximum picture quality.
- Large aperture, up to 400 mm.
Minuses:
- Structurally complex models.
- High pricing policy.
- Long period of thermal stabilization of air in the middle of the device.

Telescope for a child
For children, a telescope is not only an unusual and interesting gift, but also very useful. When choosing, experts recommend using the following recommendations:
- Children can only handle very basic telescope controls from about 8 years of age.
- For schoolchildren who are just beginning to study the sky and the world in general, it will be enough to buy a regular refractor. Its cost is optimal, the optical device is easy to care for, and its reliability is very high.
- To view the moon and nearby objects in the sky, it is enough to select an aperture of 70 mm.
- The best telescope mount for a child is azimuth. It turns out to be cheaper, easier to learn, and you can observe not only celestial bodies, but also ground-based objects.
Almost all manufacturers of optical instruments in their range can offer models of telescopes for children, which are characterized by high durability. In addition, parents are recommended to immediately buy a star map, as well as a manual for young astronomers. The average cost for simple children's models starts from 1000 rubles, but more functional and advanced devices need to be paid up to 25 thousand rubles.
The best telescope manufacturers
In specialized stores you can find a large selection of telescopes, at different prices and parameters. Although this product is not the most popular, the range is sufficient and there are many manufacturers who offer equipment.
Large companies can provide high-quality optical instruments for people of different levels. There are full-fledged models for beginners, as well as inexpensive devices for children or schoolchildren. The most functional devices that are considered professional deserve special attention. To enjoy your purchase and become the owner of high-quality optics for observing the sky, it is recommended to pay attention to the following companies:
- Sky-Watcher;
- Celestron;
- Bresser;
When choosing, you should focus not only on the brand name, but also on a number of important parameters that characterize the product. You should also determine your own requirements for the telescope, and the tips will help you choose the best option.
How to choose the right telescope for an amateur - basic parameters
If you decide to buy a telescope, you will need to highlight the main requirements for it. To do this, understand what will be viewed in the sky, where the observation is planned from (from the balcony or in the field), and whether future activities will be related to astrophography. After answering these questions, you can move on to considering important parameters.
Aperture
This indicator is the diameter of the lens and is considered the main indicator for a telescope. The aperture allows the lens or mirror to collect light and the higher the value, the more light enters, which allows you to improve the quality of the picture and catch even the faint glow of distant bodies in the sky.
When choosing a telescope by aperture for personal needs, you should focus on the following indicators:
- For maximum clarity of nearby planets, stars, and satellites, you should choose a device with a lens size of up to 150 mm. For urban conditions, it is better to reduce the value within 70-90 mm.
- If you need to look further into the sky, then a diameter of more than 200 mm is used.
- In cases where the telescope is used frequently and observation is a hobby, and the whole process is carried out outside of urban conditions, then it is best to buy semi-professional lenses with an index of up to 400 mm.
Magnification ratio
The value can be determined by dividing the focal length by a similar parameter of the eyepiece. For example, the F of the telescope is 800 mm, and the eyepiece is 16, in which case the telescope gives 50x.
Users can adjust magnification by changing eyepieces themselves, using more powerful or weaker models. At the moment, manufacturers offer options in the range of 4-40 mm, to double the focus of the device, Barlow lenses are used.
When choosing the magnification, you need to understand that detailed examination is important for close objects, for example, when viewing the Moon, and distant bodies do not require careful selection of the magnification.
Focal length
This value indicates the distance from the lens to the point in the eyepiece when all the light is collected into a beam. This characteristic determines the picture quality and magnification level. The higher the indicator, the better visible bodies in the sky.
Focus allows you to increase the length of the telescope, which has a positive effect on transportation and storage. If observation is carried out from a balcony, then it is more convenient to use models with a short focus within 500-800 mm. This ban does not apply only to catadioptrics, because in them the light is refracted many times and does not go in a straight line, so manufacturers can significantly reduce the body.
Mount type
A stand for an optical device will be required for more convenient and comfortable use. Telescopes are often equipped with a mount, which can be of 3 types:
- Azimuthal - a simple stand model that allows you to move the device in different directions. Often the device is provided with refractors and simple catadioptrics. This type is not suitable for models capable of taking videos and photos, since it is impossible to capture a clear image with it.
- Equatorial - characterized by large size and mass, but allows you to find the desired bodies by coordinates. An ideal option for reflectors that work with remote space objects. The mount is popular among people who take photos and videos of the galaxy.
- The Dobson system is a middle option between the stands already presented. As a rule, manufacturers offer it for powerful and expensive reflectors.
