Astronomy – Relationship Between Sky and Telescope!

Humans have long gazed toward the planets, stars, and many other celestial objects. Sky and telescope are the inevitable elements for astronomy or the study of planets and stars.

In simple terms, astronomy is the study of planets, stars, galaxies, and every other non-Earthly body. You can also say that astronomy deals with the study of everything that is present in space.

The telescope is the only thing that makes it possible for the astronomers to do research or study those non-Earthly objects in space. The telescope is like a link between outer space and Earth.

Let’s understand it using an example; suppose you are an astronomer and want to know about planets’ movement or spinning motion. But you can’t do that if you are not using the desired telescope for observing the motion of planets.

Astronomy and Astrophysics

Most people think that Astronomy and Astrophysics are the same. Although, both these branches of space science are indeed interrelated. But they are not entirely the same. You can also say that Astrophysics is a close cousin of Astronomy.

According to NASA’s website, Astrophysics helps you to discover how the universe works, explore how it began and how it has been evolving since the beginning. Moreover, it also deals with the search for life on planets and other stars.

On the other hand, Astronomy measures the positions, motions, luminosities, and other characteristics of celestial bodies like stars, asteroids, comets, etc.

Sky and Telescope – Which Telescopes to Use?

The beauty of the stars and planets just grab your attention and don’t put you down, especially when you love to study astronomy, or you are going to be an astronomer.

As I mentioned earlier, the sky and telescope are the inevitable elements of astronomy. You always have a sky over your head all the time. So, what exactly you need is the best telescope which you can use for the study of astronomical objects.

If you are a beginner and don’t understand how to find the best telescope for observing stars and planets, then you are in the right place. In this article, you will get to know about the commonly used best telescopes for astronomy.

Not only that, but I will also discuss the buying guide, like what things you should keep in mind while choosing the best telescope for your astronomy studies and observations. So, without further delay. Let’s hop into it!

Commonly Used Telescopes for Astronomy

The following are the most commonly used telescopes for Astronomy in 2020:

Celestron 21037 (PowerSeeker 70EQ)

Celestron 21037 (PowerSeeker 70EQ)

It is a refracting telescope with 700mm focal length and 70mm aperture size. The focal ratio for this telescope is f/10.

Theoretically, the maximum magnification it can provide is up to 140x, using the 5mm eyepiece. If you are a beginner, this telescope will be best for you because it is easy to use and setup.

The inbox eyepiece might not be of good quality, but you always have an option to replace it with a good quality eyepiece.

Celestron NexStar 4SE (Maksutov-Cassegrain)

Celestron NexStar 4SE (Maksutov-Cassegrain)

If you are a serious astronomer and space gazer, then this Maksutov-Cassegrain telescope is for you. It has a focal length of 1325mm and an aperture size of 102mm. The focal ratio for this telescope is f/13.

The best thing about this telescope is that it has a motorized mount, which makes it easier for the observer to detect astronomical objects. The maximum magnification it provides is 204x with a 6mm eyepiece.

However, the cooling time for this telescope is slow.

Orion AstroView 90mm (Refracting Telescope)

Orion AstroView 90mm (Refracting Telescope)

Orion AstroView 90mm is another refracting telescope that you can use for the purpose of astrological studies and researches. The focal length of this telescope is 660, and the aperture size is 90mm.

You will observe the focal ratio of f/7.3 with a maximum magnification of 180x using a 4mm eyepiece. The best thing about this telescope is it comes with an Altazimuth mount with slow motion control, which can be helpful for beginners.

However, some experience astronomers may find this mount not helpful.

Sky-Watcher ProED 100mm (Refracting Telescope)

Sky-Watcher ProED 100mm (Refracting Telescope)

Sky-Watcher ProED 100mm is a refracting telescope with an Apochromatic glass. This telescope is ideal for ultra-serious or pro-level photographers, astronomers, and sky gazers.

This refracting telescope comes with a 900mm focal length and a 100mm aperture size. The focal ratio for this telescope is f/9; however, the maximum magnification is 200x using a 4mm eyepiece – which is quite impressive.

The only drawback of this telescope is that it comes without any mount. So, it may not be suitable for beginners; however, they can separately attach the mount with it.

Meade LX200-ACF (Schmidt-Cassegrain)

Meade LX200-ACF (Schmidt-Cassegrain)

Meade LX200-ACF is a catadioptric telescope that makes a compact astronomical instrument by combining a Cassegrain reflector’s optical path with a Schmidt corrector plate.

It has a focal length of 2000mm and a 203mm aperture size. However, the focal ratio of this telescope is f/10. If money is not your priority, then you should buy it because it provides the best quality and maximum magnification of 333x.

However, it is not recommended for beginners.

What Makes The Best Telescope For Astronomy?

You should keep in mind a few things while buying a telescope for seeing stars. Talking of sky and telescope, a slow telescope is best for observing stars and planets.

You may know that planets and moon are the brightest astronomical object in the night sky, which means light-gathering power is not always an essential factor for observing the planets and moon.

Moreover, you should also consider buying a telescope with a higher focal length. Some other factors that you should keep in mind are focal ratio, aperture size, magnification power, and mount.

Wrapping Up!

Astronomy has created a firm bond between the sky and telescope. Beginners, as well as professional astronomers, are using the best telescopes for the purpose of sky grazing.

Now, it is time for you to select the best telescope for enhancing your reach to the more distant stars and planets.
