Telescopes for astronomy lovers: how to choose? We look at the sky

Those who like to look at celestial bodies today have practically no restrictions in manifesting their interest. It is enough to buy a ticket to the observatory and enjoy watching the stars. However, experienced amateurs are nevertheless recommended to organize the possibility of such reviews directly at home. Moreover, manufacturers of astronomical equipment constantly expand and update model lines designed for use by non-professionals. It is enough for the interested consumer to turn to the segment in which telescopes for astronomy lovers are presented. How to choose the right device is the next and rather difficult question. To answer it, you should determine the selection criteria, types of telescopes and consider the most successful models.

Basic selection criteria

At the first stage it is necessary to determine the size and basic functionality of the telescope. Home models, as a rule, have an aperture (diameter) from 60 to 200 mm. As for the length, it is in the middle corridor from 300 to 1000 mm. To ensure that observations in the telescope can be recorded and conveniently translated into digital format, it will not be superfluous to provide for the possibility of synchronizing the device with a computer. Accordingly, the model should be provided with an electronic filling and means for photographing. Such devices are more expensive, but their capabilities justify the price. With such equipment, for example, you can conduct statistical data, sending the created materials to a special database.

Now it is worthwhile to consider in more detail the characteristics that telescopes possess for astronomy lovers. How to choose the best option? The answer to this question is impossible without taking into account the possibilities of equipment in terms of increase.

Requirements for the ability to increase

There is an opinion that the increase in any optical device is determined by the aperture and the ability to provide a clear image. Roughly speaking, there are no limits for magnification in telescopes - it is enough to equip it with the necessary eyepiece. But there is a boundary behind which the observed objects become indistinguishable. That is, on certain ranges, the details and brightness begin to suffer. Therefore, the main task of a beginner astronomer is to learn how to determine the optimal magnification of a telescope in a particular model. For this there is a simple formula: the diameter of the lens in millimeters is multiplied by 2. Thus, a quality apparatus with a diameter of 100 mm will provide a 200-fold increase. This is enough to observe the clouds of Jupiter or the rings of Saturn. True, much of the benefit of applying such an increase depends on the weather conditions, but this is another matter.

Choice by appointment

There are several types of telescopes that can be classified by purpose. Those who plan to monitor the planets purposefully, it is worth recommending refractory models in the range of diameters from 120 to 150 mm. A feature of such devices is the absence of central screening, which provides a contrast and bright "picture". If it is necessary to observe distant cosmic bodies or even weak galaxies, then larger telescopes should be chosen for lovers of astronomy. How to choose the right option in this case? First, it should be a reflector on the equatorial mount. And secondly, its diameter should be selected within the limits of 200-250 mm.

There are also many fans who observe the telescope behind ground objects and phenomena. For such problems, it is recommended to use short-focus refractor models on azimuth mounts equipped with a revolving prism. If you need an apparatus with the possibility of sorties out of the house, then it is better to prefer a transportable model developed on the basis of the Maksutov-Cassegrain system. These are the so-called "marching" devices, which provide a good image, and at the same time they are light and compact.

Models for children: what to consider?

In the lineup of any major manufacturer of astronomical equipment, a children's telescope is required in several modifications. In particular, good options are presented in the Bresser Junior series. Usually these are achromatic refractors, the diameter of which varies from 80 to 90 mm. It is important that the unit is mounted on the azimuth mount for the convenience of the young user. In addition, in order to save the child from unnecessary manipulation of the equipment, it is worthwhile turning to models with a lens system. They are not particularly demanding in maintenance, but at the same time they are reliable and durable.

Very small astronomers up to 8 years are recommended devices with lenses at 60-80 mm. Such a diameter will make it possible to get acquainted with the starry sky in general terms, that at least it will cultivate the child's interest in further studies. It will also be not superfluous to supplement the children's telescope with a sky map and educational literature appropriate to age. Practical lessons of astronomy, coupled with theory, will certainly give a good result in the development of hobbies.

Mounting for telescope

This device was mentioned more than once. It provides fixation of the device and the possibility of its control. There are many options for mounting, but for amateur telescopes it is advisable to consider three varieties - equatorial, azimuthal and Dobson system. The first option will be the optimal solution if it is planned to observe subtle bodies, and also perform astrophotographic operations. Separately, it is worth considering the support, designed for transportable telescopes for astronomy lovers. How to choose the mount for this device? The best option is the azimuth system, which is also used for children's telescopes. Its advantages include ease of handling and small size. Devices built on the Dobson system also have a simple design and are unpretentious in maintenance. For a beginner astronomer this is the best option.

Telescopes of the brand Orion

The American company Orion offers a fairly extensive line of amateur astronomical equipment, so a review of telescopes should start with this product. In particular, the GoScope and Observer refractor families are distinguished. The aperture of such devices is 80-120 mm. Also, devices based on the Maksutov-Cassegrain system are widely represented. In this case, the size is between 90-150 mm. For sophisticated connoisseurs of hobbies, the manufacturer produces Aristocrat models. These are devices made of bronze, which also represent an aesthetic value. Feature of models from Orion is the supply of the latest computer devices, including guidance systems and GPS receivers.

Models from Celestron

Another American company - Celestron - is targeting, among other things, the audience of fans. The initial level in the line is represented by refractory models with an aperture from 40 to 150 mm. In the middle segment, the Dobson machines are a Starhopper series, in which you can find a large telescope with a diameter of 300 mm. The most technologically advanced line is based on the Schmidt-Cassegrain system. In this case we are talking about modifications with an aperture of 127-356 mm. It is in this class that the manufacturer realizes its latest computer developments. For example, for many representatives of the series, an automatic tracking system is provided.

Telescopes from Meade

The manufacturer Meade seeks to combine in its telescopes ergonomic advantages and complex mirror-lens systems, the aperture of which reaches 114 mm. Due to the simplified homing system, the user of such devices can easily create records and transfer them to a computer database. The maximum aperture of models from Meade reaches 406 mm, thus the telescope lens with such parameters is convenient both for the professional, and for the fan. Some devices are also equipped with blocks with time memory and horizon sensors. By the way, already in the initial economy class the manufacturer realizes achromatic refractors, supplemented by equatorial mount and homing system. The company also offers combined mounts combining the advantages of different designs.

Conclusion

It must be said that the telescope market is very supportive for novice amateurs of observing the starry sky. From anyone who wants to do it is only necessary to determine the basic characteristics, and to find a good telescope does not work. Optimal option is the device-reflector on the Dobson mount with an aperture of 100-120 mm. In terms of reliability, almost all models from the listed manufacturers demonstrate a high level and the owners do not disappoint. In this case, do not ignore the latest computer systems, which are supplied with telescopes. Despite the apparent complexity of technological devices, they are quickly mastered and in the process of operating the device significantly expand its functionality.
