Everyone who is fascinated by astronomy is faced with the problem of choosing the best telescope. Today there are so many different designs and optical schemes of the best telescopes that are produced by a large number of manufacturers. The best telescope can be available in different designs and configurations, so that a beginner can simply become confused in such an assortment and buy a model that does not fit for all the tasks. Yes, exactly what you want to observe and how, largely determines the specifications of the best telescope.
So, what is a telescope? It is an optical device designed to observe distant celestial objects. Do you know who invented the telescope? The first drawings of the most primitive devices were found in Leonardo da Vinci's notes, and its creation is attributed to Hans Lippershey and his contemporaries in 1608.
Many people buy the best telescope for semi-permanent installation in the patio of a country house under the dark sky. Someone buys a telescope for beginners to watch the planets from a balcony, and someone just wants to decorate an interior of a house or an office. In the first case, people will need a powerful Dobsonian telescope, while the others won’t be pleased with a huge pipe and massive.
Today, we will outline certain criteria and qualities of telescopes, which you need to pay attention to and which should guide you in choosing, sort out the types of optical schemes and how to mount them correctly.

The NexStar 6 SE telescope has the same functions as Celestron's most expensive computerized telescopes. Best goto telescope review proves that it is equipped with an auto-align system, including the revolutionary SkyAlign positioning technology. Among the other features, there is the starry sky tour, a database of more than 40,000 celestial objects and a simple ergonomic control panel.
Meade Infinity 102 mm is a powerful refractor on an azimuth mount, ideal for observing objects of the solar system. Thanks to high-quality optics of Meade telescopes, this device gives a bright and contrasting image with good detail. Based on Meade telescopes reviews, this model is perfectly suited for studying the surface of the Moon, the cloud belts of Saturn, the details in the belts of Jupiter and many other astronomical objects. Thanks to the rotating prism, this best telescope can also be used for ground-based observations. The kit includes three eyepieces, as well as a Barlow lens so that the device offers a wide range of magnifications.
A set of Tasco telescope and microscope will be a pleasant surprise for the researcher-amateur, so you can open a whole scientific research laboratory at home with this best family telescope! The high quality of devices will bring unforgettable impressions. The device has a 50-millimeter lens, with a focal length of 600 millimeters. Based on home telescope reviews, such a model can be used for observations not only of space bodies but also beyond the terrestrial landscape with a special lens. In addition, the scope of this model includes a 2-fold viewfinder, a diagonal mirror, 12.5 mm lenses and an eyepiece 35x. For a reliable and convenient fixation of the model, it is recommended to install it on a 15-inch desktop alt-azimuth mount.
All telescopes can be divided into three categories according to the optical scheme. These devices are refractors, reflectors and catadioptric. It is impossible to say that one scheme is better than the others; each has its pros and cons. To choose your variant between TOP 8 best telescopes, you need to understand the main differences between them all.
In these devices, the images of stars are created by the main concave mirror and auxiliary convex or flat mirrors. Refractors are divided into achromats, the so-called ED-refractors, and apochromats. The main problem with refractors is a chromatic aberration, which leaves color halos above the observed objects, which reduces the sharpness and contrast of the image. But with this distortion, you can successfully fight, accurately calculating the lens parameters, the lens rim and the air gap between the lenses, and also using low-dispersed glass and new optical circuits. The recommended objects of observation are the Moon, planets, and ground objects.
In the reflector telescopes, a concave mirror appears in the lens, which collects light into a focus like a refractor lens; the light is reflected and gathered into focus by the main mirror. The recommended subjects of observation are galaxies, nebulae and other objects of deep space. The reflector is perfect for observing the city.
Catadioptric models combine the characteristics of the previous types. The lens is a combination of a lens and a mirror. The recommended subjects of observation are the planets, the moon, stars, galaxies, nebulae.
Choosing the best telescope you need to soberly assess the housing conditions and opportunities to allocate space under the observation platform or the ability to transport the device to a remote location. Of course, you need to define your observational preferences and, based on the budget, analyze the suitable models of the best telescope for beginners offered by the sellers of astronomical equipment. Having thoroughly approached this question and made the right choice, the best telescope will give you many bright and beautiful impressions from the observations of the starry sky. So, if you are looking for the best telescope to buy to see planets, keep in mind the advice below.
The main parameter that determines the characteristics and power of the best telescope is its diameter, the aperture. The larger the lens, the more light from distant objects it will be possible to assemble in focus. A large aperture of the best quality telescope also gives a larger angular resolution, allowing you to observe more subtle details of celestial objects.
The focal length is a segment on the optical axis, which is equal to the distance from the lens to the focal plane of the telescope in which the lens has constructed the image. And the relative aperture is the ratio between the focal length of the lens and its diameter.
The focus and the luminous intensity of the best astronomical telescope play a very important role as for the quality of the images. In most cases, top telescopes with a smaller relative aperture and a larger focus are more advantageous for visual observations.
The maximum useful magnification is determined by the focal length and the eyepiece. This parameter can be changed by setting different eyepieces into the space telescope. The maximum useful magnification is the limiting value at which an image of acceptable quality can be obtained. Based on the best telescope reviews, its excess will lead to deterioration in the clarity of the picture.
The larger is the sight, the greater is the sky region visible in the infrared telescope, but the smaller are the objects. A large sight makes it easier to find the desired object by coordinates.
Convenient mounting (or mechanical fastening of the pipe) is also very important when choosing the best telescope. The most convenient type of mount is the equatorial one, allowing rotation around only one axis to compensate for the rotation of the Earth. There are still azimuth mounts that require simultaneous rotation of the device along two axes – vertical and horizontal. This type of mounting is convenient only if there is computer control or when observing ground objects.
It’s high time to tell you, what is the best telescope of 2018. So, Celestron 127EQ PowerSeeker is definitely the best telescope based on numerous characteristics. In a rather dark area, with this best telescope, you can see most of the objects from the Messier catalog, as well as Jupiter, its Great Red Spot, magnificent views of the Moon. This tool is able to fit any budget, has a stable and reliable construction and can be useful to beginning astronomers, as a universal tool. With a fairly small aperture, this best telescope in the world can solve quite serious problems. Based on telescope reviews, this model can serve as a solid base for further observations of near and far outer space on more professional instruments.
