What is a Telescope?

A telescope is a device that allows the detailed visualization of objects that are at a great physical separation distance. Without this optical instrument, it would be impossible to observe elements that cannot be directly reached by the human eye. Telescopes constitute a fundamental tool in astronomy and consequently in the understanding of our Universe.

Also for closer objects, you could use binoculars thus having a good combination for your space and terrestrial explorations.

Types of Telescopes

Keplerian or Refracting telescope

Refractors are constituted by a series of lenses for the amplification of the image, that is, they have as their principle of operation the refraction of light.

At a glance they are easily identified by the tube that is thin and long. For many astronomers, they are the type of telescope recommended for beginners.

Compared to reflecting telescopes, they are more robust and require little maintenance. Also, the images they provide are of great contrast and definition, so they are very good for observing the moon, the planets and stars.

Among its disadvantages is that the same opening is more expensive than a reflector, and when it comes to cheap telescopes, the lenses usually have chromatic aberration around the stars.

Newtonian or Reflecting Telescope

A reflector (or refrlecting telescopes) is based on the reflection of light by means of mirrors. Internally at the bottom of the tube is a large curved primary mirror (called objective mirror) that accumulates and reflects light, then the image is diverted to a secondary mirror that redirects it back to one side of the tube where we place the eyepiece.

In general they are more bulky so they are less portable than refractors.

These models for the same opening have a lower cost than a refractor, also, are easier to handle and for large aperture, models tend to be more compact. They are ideal for observing galaxies, nebulae and star clusters.

The disadvantages of the reflecting telescope are that its mirrors can be misaligned by a small blow, they need periodic maintenance to recover the reflectivity of the mirror. If it is a cheap telescope, spherical aberrations usually appear in its mirrors.

Catadioptric Telescope

Uses the principle of the reflector and refractor telescope, that is, it combines both lenses and mirrors. There are two models for this type of telescope, the Maksútov-Cassegrain, and the Schmidt-Cassegrain, however, for both models the light travels several times the length of the tube before reaching the eyepiece. This is due to:

In the Maksútov-Cassegrain the light enters through the front of the telescope, through a thick meniscus lens, which helps to minimize the aberrations produced by the mirror, then the light is reflected to the secondary mirror, and it redirects it towards the back of the optical tube, through a hole in the primary mirror, where the eyepiece is located. For its part, the Schmidt-Cassegrain telescope has the same system, only the thick meniscus lens is replaced by a thin glass plate (corrective lens).

As a sign that they are really good, they are widely used in professional astronomical observatories. Also, they are recommended for people a little more experienced using telescopes.

The catadioptric telescope has excellent optics, so they are very good for astrophotography and all kinds of observations: planets, stars, galaxies, nebulae. As their tube is short and compact, they are easy to handle and transport. The disadvantage they have is that they are more expensive than the other two types of telescope mentioned above.

Parts of a Telescope

All types of telescopes have the following parts:

parts of a telescope

Basic Telescope Features

There are values that determine the quality or power of the telescope. Here are the most important ones:


Undoubtedly, it is the main element to evaluate. While its opening diameter is larger, more light will capture and consequently more objects can be observed in better detail.

Focal length

Value related to the length of the tube and will define if your angle of view will be wider or more narrow

Focal ratio F / D

This feature determines how far you will see. It is calculated by dividing the focal length by the diameter of the objective. For example, a 150mm telescope with a focal length of 750mm will have an F / D = 5.

Keep in mind that telescopes with low F / D are recommended for deep space observation. Also, when you want to observe planets, your choice is telescopes that have high F / D.


It is often confused with how many times a star or planet looks bigger. However, the magnification indicates what the object looks like at a closer distance.

For example, Venus is at 40,000,000 km, if we use a 100x magnification, we can observe it as if we were 400,000 km away.

The magnification is calculated by dividing the focal length of the telescope by the focal length of the eyepiece.

Maximum Magnification

Although in theory a telescope can have innumerable magnifications, when a value is exceeded, the images will tend to be completely diffuse.

A rule of thumb to obtain the maximum magnification of a telescope, is assume the same number as the diameter of the scope in millimeters, or multiply the value of the diameter by 2.3.

Just remember, this works until you reach the maximum magnification of the scope, which is the same number as the diameter of the scope in millimeters.

For example, a 6 inch (150mm) telescope has a max magnification of 345x –> 150 * 2.3 = 345x.

Limiting Magnitude

Indicates the minimum brightness that a celestial object must have to be visible with the telescope.

The limiting magnitude, is calculated with the following formula:

LM = 5 x Log (Diameter in cms) + k

K is a constant that varies according to the quality of the sky from where it is observed. As a reference, the following values can be used:

  • 7 in skies with no light pollution.
  • 5 for semi-urban skies.
  • 4 for urban skies.

With this value you can compare it with the magnitude of a certain object. For instance, Venus at its brightest has a magnitude of -4.6 and the faintest star visible to the naked eye has a magnitude of +6.0

Angular Resolution

It’s the ability of the instrument to show two objects that are very close. The resolution is expressed in arc seconds and its equation is:

R = 115.82 / D [in mm]

For example, if we have a 100mm telescope its resolution will be 115.82 / 100 = 1.16. This indicates that the minimum separation that two objects must have is 1.16 seconds of arc.

Field of View (FOV)

FOV is a function that depends on the eyepieces that the telescope has. With the visual field, the portion of the night sky that can be observed is determined.

Low visual fields are used to observe planets and those of high visual field to observe galaxies.

To calculate it, the following formula is used and is expressed in degrees:

Visual field (degrees) = Apparent field of the eyepiece / Magnification

The apparent field of the eyepiece is a data provided by the manufacturer of the eyepiece.

For example, if we have a 30x magnification telescope and a 25mm eyepiece with 50° apparent field, we will have a field of view of 1.67 °; with this visual field we can see the Moon completely, since it requires only 0.5 °

In summary, the apparent field is important for the choice of eyepieces to buy because it tells us the field of vision we obtain.

Telescope Shop! The best online Store

In our telescope shop, we will guide you on the characteristics that these magnifying glasses should have.

It is very common to ask which is the ideal mount or the types of telescopes available in the market; however, the answer must be focused on giving a series of tips so that the purchase of these products will give you good results. So now I ask you: Do you dare to know a little more about this?

Quick Guide to Choose Telescopes for Sale

If you are looking for a telescope buying guide, this is the right place, since we are going to summarize the most important characteristics that must be taken into account before deciding on one option or another.

  • There are three types of telescope: refractor (with lenses), reflector (with mirrors) and compound (combination of lenses and mirrors).
  • Available mounts are also three: Alt-azimuth, Dobsonian and Equatorial.
  • The power of a telescope is not given by its magnification, but by its diameter or aperture.
  • As a rule of thumb a reflector must have an opening equal to or greater than 6 “, refractors above of 4″ and catadioptrics above of 8”.
  • To start in astronomy you can find good telescopes for sale in a range of $ 200-400.
  • The accessories to consider for your telescope are the following: adaptors, barlow lenses, cases, camera adapter, eyepieces, visual and solar filters, finders, focusers, tripods, prisms.
  • If your telescope does not have eyepieces, it is convenient to add one.
  • If you do not have enough experience, buy a Sky Guide and / or planisphere.

What is the Best Telescope to Buy in 2019?

It is not an easy question to answer, nobody can say what the best telescope of 2019 is, and much less that one brand or type of telescope is superior to another.

Likewise, a telescope for children is not the same as one for beginners or one more advanced. To clear your doubts, you must first answer: What do you want to observe? Where will you use it? How much money do you have to buy a telescope?

However, we can tell you which the best-selling telescopes are in 2019, it does not mean they are the best telescopes for sale, but it gives you an idea of the trends for astronomical and terrestrial observation.

Where can I Buy a Telescope?

It is quite common the question “where to buy a telescope?” Actually, you have many options, for example, in almost all cities there are many telescope stores. However, our recommendation is that you buy your instruments online.

On the Internet, there are many prestigious stores, but for their confidence and wide variety, we recommend buying them at Amazon, but not before reviewing our categories, which are classified for your comfort and easy choice.

Wherever you decide to buy telescopes for sale, you must first keep in mind the use you will give them and then use the buying guides that we offer.

What will you get when you buy a good telescope?

In general, you can find good telescopes for sale, whose main criteria is that at least their use and portability are acceptable and when you are ready to make observations you obtain a good sharpness and reach with distant objects.

Likewise, any model you buy should allow you to observe terrestrial and astronomical objects with good sharpness and approach.

So, when we buy a telescope and obtain all the desired capacities from it, we can say that its cost was fair in relation to cost/quality.

You can also buy cheap telescopes that provide acceptable results for a variety of uses, from terrestrial observation to astronomical observation, where we also consider that it will serve as an element of union to share with our loved ones and possibly give us the possibility to expand our Circle of friends with people interested in this topic.

As for brands and manufacturers of telescopes, we have ample room to maneuver to choose your right telescope. But do not worry or think too much, we have placed the best! so we invite you to see our catalog.

Telescope Price: 100-2000$

The telescope price range is very variable, everything depends on its quality, manufacturer’s brand, power, construction technology, the launch year of the model and other necessary and/or additional equipment for its operation.

Among the cheapest, and that generally offer a fairly poor image quality, can be around $150. Obviously, there are some exceptions, which offer quite acceptable features, such as those shown in our cheap telescopes guide. On the other hand, the price of a professional telescope can reach $2,000 or more, but they offer exceptional image quality.

In Telescopes for Sale .Net we recommend that you do not buy below $300, so that in all your observations you can detail the thousands of objects in our outer space and land. Therefore invest enough to achieve it.

Telescope Brands

The sale of telescopes from a few decades ago, has gone from being a premium market to a very popular one; due to a greater presence of telescope manufacturers.

When there are more manufacturers, there is greater competition, which has as a consequence the search to reduce the costs of manufacturing and subsequent sale, as well as the development of new technologies for customers.

In the purchase process, you should consider many factors such as the best telescope brands, in order to have a quality product and excellent technical support in case of any doubt or eventuality.

Therefore, you have entered the ideal site to know the top telescope brands. It only remains to name them alphabetically and a brief description of them so that you draw conclusions:

  • Alstar: a China brand that manufactures low-end products and acceptable quality.
  • Bluestar: it is the most economical brand of the manufacturer Synta Technology Corporation, of Taiwan, its quality is acceptable.
  • Celestron: powerful North American brand affiliated with Synta since May 2008. Its refractor and Newton models are now manufactured by Synta (formerly by Vixen). They were the ones who introduced the Schmidt-Cassegrain models and they are still the best for that category. It is highly preferred by many astronomers since the quality of its products is very high.
  • Konus: Italian firm that distributes products made in China, are low and medium range. They are acceptable in relation to the price but some models may disappoint.
  • Meade: American brand that was purchased by Ningbo Sunny Electronic Co Ltd, from Taiwan, since September 2013. Its best models are the computerized Schmidt-Cassegrain. In, general, its good quality.

  • Orion: American company bought by Synta in 2005, its products are good but not excellent.
  • Sky Watcher: manufacturer brand Synta, offers good mid-range equipment.
  • Synta: their prices are low for both refractor telescopes and mid-aperture reflectors. Its quality is surprisingly good although there are sometimes exceptions.
  • Vixen: is a Japanese company that offers telescopes of small and medium aperture with excellent quality, although their prices are quite high.

Take care of your Telescope

Telescopes are an exceptional tool both for our free time and for professional astronomers, but they are electronic items that are also fragile because they have glass pieces. For this reason, it is advisable to keep it in cool and clear places.

Once you have finished using it, do not forget to store it in its storage case. At the same time, it keeps the device clean, free of dust and moisture.

So that they do not split or fog their lenses, avoid at all costs to receive blows, falls or to get wet with the rain for long periods.

Do not forget that it is an important investment that you made to buy it, so it takes all the necessary measures in its conservation.

The most common FAQS when buying a Telescope

Our telescope shop, has received from our clients a series of queries sometimes quite repetitive, so we decided to place them as a compendium of questions and answers.

In case you cannot find an answer to your questions, please send it to us through our contact page.

What to look for in a telescope?

The diameter, the focal distance, the quality of its optics, the resolution and the luminosity are the aspects to be valued of a telescope.

How to compare telescopes?

As mentioned earlier, check the diameter, the focal length, the quality of your optics, the resolution and the brightness. These aspects will help you to decide which telescope you need.

What is the best telescope brand?

To say that one person is superior to another is to enter into an endless discussion. All brands of telescopes have excellent equipment for certain situations and really bad for others.

What we can say is that you have many options available in the market. Among the most known are Celestron, Meade, Orion, Sky-Watcher and Omegon.

What is the price of a telescope?

That depends on the features and accessories you want the telescope to have, to get started with an investment starting at $ 200 is a good start. Surely, after a while you will opt for a more powerful device, but you will require around 600 $. If you are even more demanding, the price of a telescope can be raised to $ 2000 or $ 3000, which guarantees you great images of the space.

What type of telescope should i buy?

If your observations will be to observe the Moon and the planets buy a refractor telescope. If you plan to observe the constellations and galaxies, then a reflecting telescope is your best option. But if you want to observe both planets and galaxies, then to catadioptric telescope is the one you should buy.

What is a telescope made of?

Basically a telescope consists of two elements: hardware components that allow the maneuver and focus thereof, these are made of steel, zinc alloys, aluminum and plastic (for less sensitive parts).

The second element is the optical system that is composed of mirror or lenses. The material of lenses or optical glass is silicon dioxide. For its part, Pyrex is generally used for mirror telescopes.

How much is the magnification of a telescope?

When you go to a store that offers telescopes for huge increases, completely discard those equipment. It is feasible to find equipment of 600x or higher, which offer excellent results, but for this their sizes and prices will also be much higher.

To give you an idea of what we are talking about, a 1000x telescope should have a diameter of around 500mm. These sizes exist but they are very expensive and for professional use. So finding them in any store is not easy.

It is recommended that you review the maximum increase that the telescope can support and thus you can validate it with the magnification that the store or manufacturer offers. Remember that when you exceed the maximum limit when you increase the zoom, the image will lose sharpness, that is, the increases achieved will not help you at all.

Should I include a tripod in an astronomical or terrestrial telescope?

Without a doubt! The tripod allows making observations in a stable way.

How important is the mount of a telescope?

It is extremely important, because it prevents the equipment from falling to the ground due to any imbalance.

Which mount is better azimuthal or equatorial?

Because of their ease of use, both mounts are recommended for beginners, because they are easy to use. However, the equatorial mount is more complex, but its advantage is that it allows precise tracking of the objects.

Should the mount be motorized?

To observe stellar objects, a motorized mount is not essential; they can be followed using a regular telescope. For astrophotography, we recommend that you have a GoTo system (GoTo Telescope).

Does the mount work on its own?

To begin with, these mounts can tilt one of their axes in the same degrees as the observation site, which facilitates the tracking of any celestial object.

So for the mount a follow up, first the telescope must point towards the north celestial pole or, towards the south celestial pole in the southern hemisphere.

The resolution of the telescope, what is it for?

The resolution indicates the ability of the team to show as two separate points that are very close. The lower the value, the greater the separation capacity.

What indicates the luminosity of a telescope?

It is also known as a focal relationship and is symbolized by a f. The lower its value, the brighter it will be.

Telescopes with higher luminosity are better for deep space observations and low luminosity telescopes are used to observe the Moon and the planets.

How do I choose the best telescope?

The quick response is to be guided by the opening (diameter) of the telescope. Greater openness means more light gathering, and therefore better images.

What telescope should I buy?

It’s a very common question by amateurs who start in astronomy. But more data is required to give an answer, depending on what you want to observe in the sky, we will tell you the telescope that best suits your needs (and budget). But as a general response it would be a catadioptric telescope, so you can see planets and deep space objects.

Does my telescope require maintenance?

Taking care of your telescope from dust, moisture and falls is the best remedy. Take special care in your optics. If you have a reflector, at some point it will be necessary to collimate its mirrors.

Is a telescope damaged if it is not used?

Your device will not be damaged, if you have it protected from moisture, dust, falls and blows. So try to keep it in a safe place, at a low height and away from elements that can hit or knock it down.

Would it be enough to buy a small telescope?

We are all going to want an 8-inch, 10-inch, 12-inch or 16-inch telescope to see many details, but with smaller equipment we also achieve acceptable images. For example, for many amateurs, a 4inch or 5inch telescope is enough for good planetary observation.

How much will I see with a large telescope?

For certain diameters and types of telescope, we have certain references; For example with a refractor telescope that is between 2.5 “and 4” in diameter, you can see Saturn’s rings, Jupiter’s belts and make good lunar observations.

On the other a 6 inch reflector telescope (newtonian telescope) allows you to see more clearly the Jupiter’s belts and make good observations of deep space. With 8-inch reflector telescopes you get fabulous results in astrophotography and deepspace observation. It also allows appreciating the Cassini division of Saturn, and with better detail to the galaxies.

Reflectors above 8inch are considered powerful telescopes, because they allow observing many details.

What disadvantage can a large telescope have?

Its weight and difficulty to transport. Therefore, it is recommended that they be installed at a fixed point of observation. If you are an amateur, avoid the hassle and consequent laziness due to the transport of the equipment, this will help you to never cancel observations.

What is a dobson telescope?

A dobson telescope is one that has a dobsonian mount (as the name implies). It is a reflector telescope mounted on an azimuth mount. Due to its simplicity and low cost for large diameters, many fans have been inspired to manufacture this type of mount for their devices.

What is a catadioptric telescope?

It is a telescope of great power and quality because it combines the characteristics of a reflector telescope and a refractor. Within the catadioptric, the most known model is Schmidt Cassegrain and secondarily Maksutov.

Catadioptric, reflector or refractor telescope which is better?

To summarize, under similar sizes refractors are the most appropriate for observations of the Solar System while reflectors are better for observing faint objects such as galaxies or nebulae. By On the other hand, the catadioptric telescope is very good for astrophotography and all kinds of observations: planets and galaxies.

What are the advantages of a Schmidt Cassegrain telescope?

Its main advantage is its compact design for easy transport, which makes it very popular for amateurs of astronomy. This telescope combines an easy manufacture of the spherical surfaces to create an instrument with the long focal length of a refractor to lower cut by opening the reflector telescope. Among the best-known brands in the construction of this type of telescope are Celestron and Meade.

What is a Maksutov telescope?

These telescopes are characterized by the use of a spherical main mirror simple to manufacture and a concave correction lens with a negative meniscus. What allows to correct problems of spherical and chromatic aberration.

These devices provide good magnification power but with a relatively narrow field of view, making them excellent for observing isolated elements.

What can you tell me about a Ritchey Chrétien telescope??

The Ritchey-Chrétien telescope or RCT provides a wide field of vision compared to its original design (Schmidt- Cassegrain), because it eliminates the comatic aberration. RCTs are commonly found in large professional observatories. For example, the Hubble telescope has a variant of this system.

What are achromatic refractor telescopes?

An achromatic refractor uses two pieces of glass of differing optical properties to correct chromatic aberration. This correction is achieved by focusing two colors at the same point. Their configuration makes them the cheapest refractor telescopes in the market.

What qualities do apochromatic refractor telescopes have?

Apochromatic refractor telescopes (APO telescopes) have a better correction of chromatic and spherical aberration than achromatic lenses. So, you will get a cleaner view at the night sky. APO telescopes are very sought after by amateur astronomers although their price is quite high.

I live in a city, what is the telescope to buy?

I’m sorry to disappoint you, if you’re in a city observing objects such as galaxies or nebulae will not be as good. In the city, you can mostly use your telescope to make planetary observations. If you do not have many exits to use the telescope, then buy a more powerful telescope. For example a 6″ refractor, an 8″ reflector and a catadioptric above of 8 “.

What is the best telescope for a place of low light pollution?

This tells us that you live outside of a city, so you do not need to move with the telescope. So you have two options, the first, if you just want to have regular observations without so much detail, buy a small telescope. The second option is to buy a large telescope and use a site as a home observatory, there you can enjoy in its entire splendor to our wonderful universe.

What is the best focal length?

I’ll clarify, that depends on the consumer. If you want deep space observations, your choice should be a telescope with short focal length. If you like to observe planets, then you should opt for a telescope with a high focal length. Also, if you want versatility in your observations, a medium focal length of around 1000mm to 1200mm is recommended.

What is the meaning of a telescope being fast or slow?

These are quite confusing terms since this feature does not indicate that one telescope is superior to another. Slow telescopes are those with a high f (greater than 6), ie the lens requires a longer time to capture the image correctly, which does not make them ideal for astrophotography

What function do the eyepieces have?  

The function of the eyepieces is to modify the magnification in the telescope.

What is the purpose of the finderscope?

The finder is used to aim the telescope at the object to be observed. In addition, it allows focusing the stellar object. The same is a “mini telescope” with low power that is on top of the telescope.

Why are the images inverted?

They are inverted by the path of light inside the astronomical telescope. In the same way there is no greater importance in this, because in space there is no up or down. To correct the image an additional lens is required; as a negative point is that the images will look less sharp.

Can I build a telescope myself?

If you do not have haste to make observations of space, it can be rewarding to build a telescope. Remember that building a telescope will require time and money.

As for the construction costs, we tell you that they do not get too cheap in relation to buying it in a telescope store.

Can you build a powerful home telescope?

As we commented, the difference in the price-quality ratio between a homemade telescope and one made in optics can make you go backwards in building a homemade telescope.

However, with patience, good investment and good technique, you can have one similar to those offered in a store telescopes.

What accessories should the telescope have?

Really not many, if you are initiating a pair of eyepieces it is enough for you to observe both planets and stars and galaxies, so it is enough with one eyepiece of high magnification and another of low magnification.

Consider buying a barlow lens with good optics, because it will be very useful.

To see the planets, do I need to buy color filters?

If you are an amateur astronomer who recently began his observations, you will not need to buy these accessories, it is sufficient to have a good eyepiece. With some experience you will notice the benefits of color filters once you have purchased them

It is useful to buy light pollution filters?

You should know that to make observations the ideal is that you go to a place of little light pollution. The filters improve the image of planets a little but they do little with galaxies and star clusters.

Do not be fooled, these filters significantly improve the observations but they are not magical.

Should I consider buying it with special coatings?  

The numbers speak for themselves, the light transmission increases by 15% with these coatings, and already know greater light has better images. So it’s an excellent idea to buy them!

Will it be easy to perform astrophotography with my telescope?

Neither easy nor difficult. Consider that astrophotography does not consist of pointing the telescope, click and go. The form correct it requires a motorized telescope and a good camera. Of course, then there is the work of image processing and editing.

In addition, to perform astrophotography with your telescope, you should also consider that the motorized mount has different speeds: solar, lunar and sidereal.

I want to start in astrophotography, what do you advise me?

Use the Moon to get started in astrophotography. This natural satellite is very easy to locate and has very good luminosity. With this astro, the learning curve will be shorter in terms of the operation of the telescope, operation of the camera and image editing.

Can I use a webcam for astrophotography?

Yes, you can! but you should know a bit of electronics to make adaptations in its circuit.

Are terrestrial telescopes good for astronomy?

Spotting scopes are not a good option for astronomy, mainly because you will not be able to observe with good detail and clarity what you intend to observe. Even in some terrestrial telescopes changing eyepieces is not possible.

I need versatility, a telescope that is used for astronomy and for terrestrial observations

A starting point would be to consider a pair of binoculars 20×70 or similar. If you still want it to be a telescope, discard the reflectors and look for a refractor of no more than 4 inches.
