What is the best telescope on the market?

We love to aim high, that is why we are passionate about observing the depth of landscapes or the distance of the sky, much more if we can see clearly and magnified, that is why the telescope is the best tool for this task.

So this telescope comparison offers you the most complete guide so that you can choose without problems and in the most optimal way possible that will ensure you buy the best cheap telescopes.

They offer a large number of potentialities, functions and accessories to give you the best optical experience , however there is a lot of variety on the market so this comparison will help you know how to choose your telescope.

Tips for choosing a good telescope

To know which telescope you should buy, you must take into account some recommendations , such as the different models and characteristics of each one:

Aperture: This is the main focus point when choosing the telescope and it means the useful diameter of the lens, the larger the aperture it will provide us with sharper and clearer images because it absorbs more light than it gives you images with more brightness, so depending on what you want, choose a telescope with a larger or smaller aperture.

Types: There are three types: r efractors that offer apertures greater than 100mm are very luminous and heavy, for planetary observation of 90mm and 60mm it is for observation of open space. The reflectors, also called Newtonians , use mirrors to capture light and are available in sizes such as 110 or 150mm and retro-reflectors have high -light capture optics , use a combination of mirrors and a correction lens.

Mount : There are several types of mounts and they can be moved in the up-down, right-left directions , the higher quality allows better precision. They have several types as you need, the Dobsons are horizontal and are made of wooden pieces, the equatorial ones rotate around a single axis to follow the stellar movement and the fork ones are more used in catadioptric telescopes allow turns like equatorial ones.

Finder : The best telescopes must have a finder that works like a small telescope attached to the side of the device, which has the great utility of pointing and locating objects, the most used are reflection in which you look in a window, you see a Red point where the exact place where the telescope is pointing is located, likewise there are three types 5X24, the best are 6X30 or 8X50.

Eyepieces : The eyepieces are what give us the magnification and these are a piece that can be changed in the telescope to add the level we want, however it is advisable to have at least three eyepieces, one of 25mm to observe diffuse objects with little magnification, 8 to 12mm to see with intermediate magnification and another from 7 to 10mm to see objects that need a lot of amplitude, they also differ in quality.

How much money should I spend on my telescope?

Knowing the prices of the telescopes is an important point when it comes to your choice and that is because this goes very hand in hand with the quality you expect to receive and the functionalities you highlight.

• Cheaper telescope (less than € 100) – They are more for amateurs, they do not have great features, they are rather commonly used and their quality is medium low, in addition to the accessories they are more limited.
• Better quality telescope (more than € 100) – With these you can carry out different types of activities, many are for professional use and provide you with different applications, and they also give you the sharpest image.

How to use a telescope?

If you’ve just decided on one, but don’t know exactly how to use it, this telescope comparison is the best and shows you through a series of steps:

• Mount – Attach the three legs of the tripod to fix it and then direct it to where you expect to view. Each leg is fixed with a large bolt.
• Balancing – Release the counterweight and move it so that it balances the telescope. Readjust the counterweight.
• Observation – You should initially use your telescope in daylight when it is easy to locate the knobs and viewing direction so that when we use it at night it is easier to locate.
• Visualization – Try to find a clear object that is more than 200 meters away and point the telescope at the object.
• Focus – Turn the focus knob gradually until your subject is clearly in focus.

What types of telescope are there?

There is a wide variety of models, but which is the best telescope on the market? Well, first we must know the different types available.

1. Refractors – They are the most suitable for beginners and have the objective in the front end of the tube, it is easy to handle and move, with apertures of 100 to 60mm.
2. Reflectors – The objective is a concave mirror located at the rear end of the tube, they are usually wider and shorter, they are somewhat brighter, and their way of handling it is less intuitive, with an aperture of 110 to 150mm.
3. Retro – reflectors – They are powerful and of high quality with a complex but compact design, they have some computerized models, also the objective is a concave mirror and with a correction lens that supports a secondary mirror. It is easier to transport and handle.

Parts of a telescope

If we know the parts of the telescope, it makes it easier for us to understand its operation and even use certain parts in specific functions:

1. Optical tube – It is the central part of the telescope and it is what supports the optical system and connects it to the physical system.
2. Lens – The optical building block that enables all viewing.
3. Eyepiece Holder – Holds the eyepiece, this piece can be easily changed and allows fine focus.
4. Eyepieces – They are the secondary lenses that allow magnification, they can also be changed according to the magnification level you want.
5. Mounts – Includes the mechanical elements to move and support the tube.
6. Finder – Similar to a telescopic sight, not all have them but it allows to locate exactly where the telescope is pointing.

Advantages of using a telescope, what are its strengths?

Every product has focus points, which is where you can see the advantages they offer and as expected that telescopes are also that analysis for this article, so we must highlight their strongest points.

What are the advantages of using a telescope? Its advantages are:

1. They allow you to see objects at long distances that are imperceptible to the eye.
2. You can get sharp and bright images in dull scenes.
3. You can explore space or landscapes in an augmented way.
4. With its large opening p ermite capture more light compared to other optical objects.

Who Invented the Telescope?

Although there are many doubts about the real inventor of the telescope, it is attributed to the optician Hans Lippershey, in 1608 in Middle burgor, Netherlands, as a tube-shaped instrument that contained lenses with which he could see distant objects as if they were close. and it did not have a patent at the time so it quickly spread throughout Europe without copyright.

What is a telescope?

It is an optical device that helps us to visualize distant bodies in more detail that cannot be seen with the naked eye, by capturing electromagnetic radiation, such as light. It is also a vital device in astronomy, and thanks to the technological advances obtained it allows us to increase our understanding of the universe.

Likewise, this device allows us to see something that is far away, in a more detailed way than if it was observed only with the eyes. It therefore offers an expanded image of the observed object.

These equipments offer you quality optical visions and easy to configure designs, the moment you want to admire the sky, they improve the observation capacity giving you the opportunity to visualize hundreds of elements with impressive clarity.

Telescope Features

It is relevant to know that the most significant parameter of this device is the diameter of its objective lens. Generally, an amateur telescope is between 76 and 150 mm in diameter and allows you to see some planetary details and many deep sky objects such as clusters, nebulae and some galaxies.

On the other hand, devices that exceed 200 mm in diameter allow to see fine lunar details, important planetary details among others. In this sense, to characterize and use them, a series of parameters and accessories are used:

• Focal length: is the focal length of the telescope, which is defined as the distance from the mirror or the main lens to the focus or point where the eyepiece is located.
• Objective diameter: is the diameter of the primary mirror or lens of the telescope.
• Eyepiece: it is the small accessory that placed in the focus of the telescope allows to magnify the image of the objects.
• Barlow lens : this lens usually doubles or triples the magnification of the eyepiece when observing the stars.
• Filter: it is known as a small accessory that generally dulls the image of the star but depends on its color and material, which allows better observation. It is located in front of the eyepiece, and the most used are the mole (bluish-green, improves contrast in the observation of our satellite), and the solar, with great power to absorb sunlight so as not to injure the retina of the eye .
• Focal ratio : is the quotient between the focal length (mm) and the diameter (mm) (f / ratio).
• Limiting magnitude: it is the maximum magnitude that can theoretically be observed with a given telescope, under ideal observation conditions.
• Tripod: it is a set of three generally metallic legs that give support and stability to the telescope.
• Eyepiece holder: it is a hole where the eyepiece, focus reducers or multipliers are placed, for example, Barlow lenses or photographs.

Mounts used by telescopes

There are many types of frames according to the degree of perception that you want to obtain, then we will name them with their respective details:

• M altazimutal onturas: is a simple mount. It is similar to that of a theodolite. One part rotates in azimuth (in the horizontal plane), and another axis on this rotating part, also allows to vary the inclination of the telescope to modify the altitude (in the vertical plane). A dobson mount is a type of altazimuth mount that is very popular because it is simple and inexpensive to build.
• Equatorial mount: the best solution for small astronomical telescopes is to tilt the altazimuth mount so that the azimuth axis is parallel to the axis of rotation of the earth; this is called an equatorial mount. It should be noted that there are several types of equatorial mount, among which the German and the hairpin can be highlighted.
• Other Mounts: In this regard, large modern telescopes use computer controlled altazimuth mounts that, for long exposures, either rotate the instruments, or have variable rate image rotators on a polished image of the telescope. There are even simpler mounts than altazimuth, usually for specialized instruments. Some are: meridian transit (altitude only), fixed with a movable plane mirror for solar observation, ball joint is now obsolete and useless for astronomy.

How to mount a telescope?

Properly positioning a telescope will allow you to easily fix the objectives or move it without having to do complicated maneuvers to aim at the objective. This instrument uses two types of mount, one is the altazimuth, which is ideal for beginners, since it facilitates movement from top to bottom and from side to side, and the equatorial mount that uses a polar axis, which is the part that rotates the telescope, which must be aligned to the North Star, this makes it follow the movement of the sky focused on this point.

Every time you go to observe a star, you must unlock the axis and fix it when you have already located the target. Once set, use the controls to make small movements.

How to choose the right place to use a telescope?

When you dedicate yourself to observing the universe, it is necessary to have a telescope at hand, you also have to consider the place where you are going to use it. It is important to bear in mind that, in order to have good visibility of the space, you must be in a place free from light pollution, since, otherwise, you will have poor visibility, even if the telescope has good power.

Also another element to consider is the frequency of the rain in the place where you are going to be to use your telescope, the humidity that the rain produces affects the atmosphere and the lens or mirror that the telescope uses.

How to focus a telescope?

With regard to these teams, the focus of the image is vital, either to obtain excellent photographs of space or just to observe the cosmos. When the image shows signs of a blur, the display becomes an obstacle and the images may have a weak brightness, the same can fall below the threshold that the sensor captures. To solve this situation you can optimize the focus by applying the visual focus technique.

This technique is one of the simplest of the focusing techniques and consists of rotating the focus ring or wheel, until a sharp image appears focused in the viewfinder of your camera. Depending on the lenses and eyepieces you are using to mate with the tube, the focus point may vary.

This technique is very useful for a first approximation, however, it is not considered reliable when it comes to astrophotography. For this, an optimal approach will be given when you manage to minimize the size of the stars as much as possible.

Which telescope is better, refractor or reflector?

When we talk about those who are passionate about astronomy, there have been two really irreconcilable groups for a long time, those who bet on refractor models and those who favor reflectors. Despite the fact that these two devices differ from each other by certain characteristics, the truth is that the optical laws work in the same way for both.

Let’s start with the refractors, these devices tend to be more voluminous, expensive and heavy when they have apertures that reach 100 mm. This is why you can usually get these devices with diameters ranging between 60 to 90 mm, with which you can observe clear images of the planets and the moon.

However, with these very small diameters, the visibility of a deep sky is limited, thanks to the fact that refractor telescopes are the most appropriate when it comes to planetary observation, but not to observe diffuse or faint objects in the universe.

On the other hand, the reflector-type ones, do not have the expensive optical lenses that refractors use and instead, use a parabolic mirror to capture the light, they are also called Newtonians. Their diameters can reach from 110 to 150 mm, therefore, by having a larger aperture, they are capable of providing sharp images of both galaxies and nebulae and stars. Thanks to this, they are the indicated ones to visualize the deep sky.

Which telescope is more useful terrestrial or astronomical?

When we have to decide on one of these teams, it will depend solely and exclusively on the application that you are going to give it. On the one hand, we have the terrestrial design that is usually very similar to an astronomical model, but has a smaller size and with certain technical modifications.

Its use is intended for those who are lovers and scholars of birds and animals in general, as well as for field scientists who are dedicated to analyzing life and wildlife.

Likewise, these devices have a structure that is easy to carry, since the animals under observation are in constant movement, so it is necessary to move the device to different places. It should be noted that, it has much less magnification than its astronomical congeners. However,

On the other hand, we have the astronomical ones, which are used mainly for night observations of the sky, it is important to know that these devices are large and in some cases heavy and it is not necessary to be moving them, you only need a specific tripod to mount and focus. to the sky.

In this sense, the most convenient to use is the one that for the moment can cover the need and give it the specific application to meet the given requirement.
