Since its inception, the design of telescopes has undergone significant changes. Now, in order to view craters on the surface of the Moon, to observe the change of seasons on Mars, it is enough to buy a compact telescope and turn a veranda in a country house or a balcony in a high-rise building into a real observatory.

The principle of operation of all telescopes is the same - lenses collect light rays, focusing them at one point. The larger the lens surface, the more detailed and sharper the image.
Depending on the design features and the method of “working” with light, telescopes are divided into 3 main types:
For beginners, refractors are suitable. No complicated settings, built-in electronics - everyone can manage them. The price of such models is more than acceptable, and the functionality is enough to consider most of the objects of the solar system. The only drawback when used in urban environments is street lighting, which can light up the picture. Therefore, it is better to watch the starry sky somewhere outside the city. By the way, most refractors have a collapsible design, so there will be no problems with transportation.
Mirror telescopes are more suitable for adults. To cope with a lot of settings to get a good image, it will be difficult for small users.
In addition to the design itself, it is worth paying attention to the following device parameters:
As well as resolution indicators - the higher they are, the more detailed the image (when using a telescope, it will not be possible to consider objects that are close to each other separately, one, double, will be visible).
It is also worth paying attention to the dimensions. If you are going to study the starry sky from the balcony, choose compact models.
It is worth paying attention to the mount of the telescope. In this case, the mount is the part of the structure on which the optical tube is mounted. It consists of a base, two axes responsible for the rotation of the pipe, a drive and a system for reading the rotation angles.
It is from the mount that the convenience in work, the reliability of the installation of the device in the working position and ease of control depend.
There are only 2 types of mount (not counting the various variations) - these are equatorial and azimuthal. Each has its own merits and demerits. For example, the Azimuth mount is an easy-to-use and stable mounting system with intuitive controls that even a child can handle. Telescopes with an azimuthal mount are more compact, so you can easily take them with you to the country.
Devices with an azimuth mount usually cost an order of magnitude more expensive, but allow not only to consider dim and distant objects, but also to engage in astrophotography. The main disadvantage of such telescopes is their large size and complicated setup process, so they are hardly suitable for beginners.
Telescopes are better to buy in specialized stores. Firstly, sales consultants will talk about each model from a professional point of view, without unnecessary advertising and attempts to sell a bunch of additional upgrade consumables. Such advice will be especially useful for beginners. Secondly, the choice of optics in specialized stores is several times larger, in contrast to the same hypermarkets.
The telescope can also be ordered via the Internet, just check the reviews about the site and ask a couple of questions to the manager.Ideally, the seller’s website should contain not only product cards with minimal characteristics that will tell absolutely nothing to a beginner, but also a detailed description of each model. And, yes, to eliminate the risk of damage to the optics, choose courier delivery.
When compiling the rating, user opinions, price-quality ratio, ease of use and ease of settings were taken into account.
Telescopes for children are compact devices with a small lens diameter (from 40 to 70 mm). The main difference from more expensive counterparts is the ease of operation. When choosing, pay attention to the reliability of the pipe attachment and the stability of the tripod.
Compact refractor, weighing only 1.3 kg, with intuitive controls and alt-azimuth mount. A height-adjustable tripod is included. Of course, it will not work to see dim stars through a telescope lens with a diameter of 50 mm, but the rings of Saturn or lunar craters are completely. The telescope can also be used to observe terrestrial objects - to bring a flying plane closer, or to consider clouds in the sky. In general, a good, educational toy for little money. Plus a great idea for spending time with your child.

The multi-coated lens with the supplied Barlow lens (responsible for increasing the effective focal length) gives a clear picture. The swivel pipe is securely attached to the base with screws, the control is carried out manually, with a micrometer screw in height.
Together with the telescope, the buyer receives everything necessary to start observing - 2 eyepieces for 26 and 9 mm, a direct image prism and a Red Dot finder. All accessories can be placed on a special shelf, which is mounted on a tripod.
Price - 7200 rubles
Compact device with 60 mm objective lens. Thanks to high-quality optics and multi-coated optical surfaces, it is considered one of the best telescopes in its class. Allows you to examine the stars, nebulae in detail. And thanks to the built-in StarPointer finder, you can find any object of interest. Can be used as a spyglass for observing nature.
Mount - alt-azimuth, standard for models of the budget price segment. Steel tripod provides a stable position, adjustable in height. The kit includes two eyepieces for 10 and 20 mm, a shelf for storing accessories and a disk with TheSky X program, which will tell the user about distant galaxies, the solar system.
Price - 24000 rubles
A small achromatic is perfect for observing the Moon and the planets of the solar system. The lens with 70 mm diameter forms a clear picture with minimal optical errors (the same chromatic aberrations). A multi-layer coating of lenses makes the picture clear.
