How To Find A Good Telescope for Beginner

What is the best beginner telescope?

If you’re a neophyte to the world of Astronomy and you want to jump right away to the action, below you will find a selection of the best telescopes for beginner. I’ve spent many hours to put it together and I think that it represents with no doubts a selection of the finest and the most competitive models available in the market today.

Depending on your budget, you’ll find your best beginner telescope.

A selection of the best telescopes for beginners

If you, like me, have developed since long time a strong curiosity for the mysterious shining lights over your head during the night, you’ve come to the right place.

Initially fear was great, and all that complicated information about telescopes for newbies seemed impossible to understand, but thanks to my – and hopefully our – passion for discovery, you will be finally able to see clearly. Having a telescope does not just mean looking at the stars.

With a telescope you have access to a huge world, unknown to many people. The Moon, Mars, Saturn, Uranium and other deep space objects you don’t know yet, will finally be accessible.

In this site I put at your disposal all my experience, my secrets, my tips, and above all my Love for the world of astronomy, accessible everywhere.

I hope you will appreciate my selection of guides, tutorials and products review that are designed for an exigent public, that wants to have the best value for their money.

What is a telescope ?

With the word telescope we indicate an instrument used by astronomers to observe the celestial sphere and space objects. They’re usually classified by their capability to perceive light radiation.

We distinguish two main categories: optical telescopes and gravitating telescopes.

The first are placed on earth surface. They can be found in stores and you can easily own one and place it at home. Subsequently divided in two families:

All optical telescopes needs to be oriented to the objects we want to look at. This can usually be done either manually or through a finder, a basic system that use coordinates to point the instrument to the right direction.

Gravitating telescopes are, instead, floating around terrestrial orbit. They provide scientists and professional astronomers a better observation and definition, thanks to their physical position above the atmosphere zone.

What really matters when we want to buy a telescope?

You should keep in mind that all kinds of instruments and any configuration of telescope, has two basic parameters to consider and evaluate:

  • diameter of aperture, the actual surface of the objective lens, which is usually expressed in millimeters and by the D letter;
  • focal length, the distance between the primary lens, or mirror, and the spot where image gets the best focus, measured in millimeters and expressed with the F letter.

These two variables are fundamental to obtain the value of the focal ratio, which is commonly used when defining a telescope power, as you can see in the image below:

Focal Ratio value

As a rule of thumb the bigger the diameter of aperture, the more light can be captured by telescope. You should not necessarily choose an expensive telescope, with huge diameters, but keep in mind that any increment in diameter size will let you gain up to four times more in terms of collected light and image quality. So if we have an increment of 30 millimeters in diameter size we’ll be able to capture 66% more light, with obvious benefits in terms of result.

If you ever went to take a look in a store you will probably remember all the big fancy numbers on the boxes, claiming that telescope X has a magnification power of 400x or more. Should we trust them?

And, most of all, what do we mean when we use the word magnification? Keep reading and you will be pleased by what you will see.

Magnification is obtained dividing the focal length F by the focal length of the eyepiece F’.

Let’s say our telescope has a focal length of 1000 millimeters and an eyepiece of 50 millimeters, intended to give you a wider view. What is the real magnification power?

Let’s divide F by F’, so 1000/50 which will give us a magnification value of 20x. If you want to avoid having blurred or unsatisfying images try to keep magnification value within a reasonable range, do not overpass 60/70x even though I understand it seems attractive to have a 200x magnification.

Eyepieces are easily interchangeable, and there is a wide variety of them. You can customize your telescope, now that you know what to consider when choosing one.

To sum up:

  • Stick to a short focal ratio if you’re looking for a brighter image of closer objects.
  • Choose a longer focal ratio if you need to work with higher magnification values.

What makes my telescope’s focus improve?

Three parameters influence the capacity of focus of your instrument:

  • The quality of eyepieces and optics;
  • How well they are aligned, also known as collimation;
  • The focusing system.
