How To Choose The Best Lens For Astrophotography

The photographs of the universe are characterized by being astrophotography and have always been a spectacle to admire that, sometimes, makes us think that they are not real. But the truth is that behind them there is not only dedication but good teams. So if you want to photograph the galaxy or astronomical objects you must have the best ones, as is the case with the lens.

By having this component of the camera you will be able to take great photographs of the Milky Way and everything that makes it up. That is why you must purchase the one that meets all the necessary characteristics. So if you want to know what would be the best lens for astrophotography, read on. Because below we will give you the necessary tools to make it very easy to choose.

The characteristics of a good lens for astrophotography

Astrophotography is an art and to capture beautiful shots of the universe we must have good photographic instruments available. The objective is one of the most indispensable. This is because with it we will obtain the desired angles and will allow us to appreciate the Milky Way in detail. But, to achieve this, the objective must be the best and for that it must have the following characteristics:

Finding the best lens for astrophotography

Focal distance

For good astronomical photography, the lens must have an exceptional focal length. And it is that the focal length is responsible for indicating the spatial capacity that a lens can have. In other words, this factor will help us determine the field of view that can be captured through the lens.

That said, you should know that having a lens with a greater focal length will achieve a wider shot. So, to choose your ideal lens, you have to keep in mind what you want to capture. And it may be a shot of the sky or a specific astronomical point.

Also, there are lenses that have a short focal length; that is, the lens is more closed. In astrophotography, this type of lens is excellent for taking close shots. As can happen in those cases in which it is required to photograph the galaxy or a constellation in detail.

On the other hand, if you are a person who loves to play with angles and spaces, there are goals for you. These are those that will allow you to vary the focal lengths according to your wishes. And they are called in the photographic world as zoom lenses.


Another key factor to consider when choosing the best lens for astrophotography is the aperture of the lens. And it is that the opening of a lens is what will tell us how much light it is capable of catching. Which is important, since in astrophotography you work a lot with natural lights, such as the brightness of the moon.

These productions always take place under night landscapes, and the darker the scene, the better the objects can be captured. But, to perfectly visualize the sky and the stars, the aperture parameter must be ideal.

You have to keep in mind that the larger the aperture, the more light will enter the camera. This means that the elements within the scene you are trying to capture will be noticeable more clearly and brighter. That said, you need to evaluate what kind of sky scene you want to shoot to acquire the lens with the best aperture.

On the other hand, there are lenses that give you the option to adjust the aperture. So you can play with light when shooting and you will not have to use the flash. However, care must be taken since if it is not handled properly there may be problems in the shots. As is the case of distortion in the stars or in a ray of light.


The composition of a lens is another extremely important factor in astrophotography and is closely related to focal length. This is because composition helps determine the space and elements that will be projected on the screen. That is, it serves to establish the perspective that all the sets of the photo will have.

For astrophotography there are so-called wide angle lenses. These are capable of projecting a wider scene on the screen, as well as creating various changes to the shot. As is the case that some large elements, such as trees or mountains, look more regal.

Also, this type of lens can create distortions in the lines of the photograph, which usually occur at its edges. Likewise, this effect can make some objects in the center of the photo appear smaller. So you must have a good composition to know what the focal points and their ornaments will be.


It is an essential element for taking astrophotographs. And it is that, when wanting to print a photo it is necessary that the bright elements are reflected in detail. As is the case of the stars or the moon.

For that, you must have a lens capable of perfectly capturing these components of the sky. So there should be no coma aberrations when photographing. These are usually caused by minor flaws on the lens glass surface, which cause distortions in the lights. So it is important to review those items before purchasing one.


Astrography is a style of photography that has earned the love and admiration of many. That is why more people have decided to venture into this type of art. However, and as we have seen with the objective, excellent pieces with specific qualities are needed.

In this case, the objective is essential to be able to develop detailed photographs of the galaxy or some astronomical element. And lenses of this type abound on the market; however, the previously described specifications must be kept in mind. Since that will ensure that the photos are of extreme quality.

The decision on which is the best lens for astrophotography will depend on the style of your photos and what you want to capture on screen. Although, it is essential to comment that there are currently brands that are committed to objectives for this type of work. As is the case with Sony and Canon, which, in addition, can be easily adapted to your EVIL. So the decision is yours alone.
