Astronomical Landscape Photography is a subset of night photography. This type of photography may be difficult for those who are new to photography, as they typically encounter a variety of obstacles when shooting in low light, let alone photographing the night sky and the Milky Way.
Of course, in this article we want to tell you that taking spectacular photos of celestial bodies is not as difficult as it first seems. In fact, in this article we want to say what kind of photography is called astronomical landscape photography and then teach people who have just entered the world of photography the best tips for capturing this type of photography.
Astronomical Landscape Photography What?
Astrophotography is a broad genre of photography that includes a variety of genres, including landscape photography, planetary photography, solar photography, and moon photography. In all of these styles of photography, the photographer tries to photograph the sky and its associated objects. It is storm photography and sea photography. In fact, in this style of photography, the photographer seeks to capture images of environments that exist in nature.
Astronomical landscape photography is a combination of these two types of photography styles. In this type of photography, the photographer tries to combine the earth and the sky in the photos taken. In fact, in this style of photography, the photographer captures the outside world in such a way that the sky is the main subject in the composition.
Of course, we must say that like other photography styles, astronomical photography requires knowledge of They should be used when shooting in this style in order to capture the best possible photos. In fact, your main goal when shooting in this style is to do something without damaging the final photo, as much light as possible enters the camera and reaches the sensor.
Now in this part of the article we want to Let's take a look at some of the things that beginners need to know about astronomical landscape photography.
Find the right place
Sky photography is not easy enough to go outside and photograph the sky. In fact, you should have a specific plan before doing this. You can use the Light Pollution Map site to find places that are far from cities and have minimal light pollution or no light pollution.

2. Get ready for the night
As we said, astronomical photography is about photographing celestial bodies, and normally these celestial bodies cannot be seen in daylight. This means that you have to prepare for night photography.
The times after the blue hours at the end of the day to the blue hours at the beginning of the day are good for this type of photography. Midnight is also a great time to photograph the Milky Way. If you want to have the moon in your photo when photographing the night sky, you can download apps that show the moon state, which shows you the state and location of the moon at different times.
It is also important to note that when doing this type of night photography, it is best to wear warm gloves and heat generating packs. Take it with you so that you do not have a problem with the cold of the night while working with your equipment.
3. Choose the right camera
If you are new to photography or want to experience astronomical landscape photography, you may be wondering what features a good camera needs to do this style of photography.
As you know, cameras with full-frame sensors typically perform better in low-light environments because the sensors used in these cameras are more sensitive. Of course, we have to say that cameras with crop-sized sensors also work well when shooting this type of photography, especially if you have not yet found your shooting style and are trying different styles.
If you are You are currently using a DSLR or mirrorless camera with a crop-sized sensor. There is no need to buy an expensive camera with a full-frame sensor.

4. Use ultra-wide-angle lenses
Using ultra-wide-angle lenses allows you to capture more of the scene in your photo. Ultra-wide lenses are ideal for astronomical landscape photography. Because the sky is the main element when shooting in this style and you want to have as many different elements of the environment in your photo as possible.
A look at wide-angle lenses shows that these lenses typically have a focal length of 14 to 35 mm. The ultra-wide-angle lenses on the market also have a focal length of 8 to 16 mm and can give you a 180-degree viewing angle when shooting. Of course, if you do not want the final image to be distorted like Fish-eye lenses, do not shoot with ultra-wide lenses in this style.
5. Use fast lenses
Using fast lenses is essential for shooting in low light environments as these lenses allow a lot of light to enter the camera and reach the sensor. Fast lenses are lenses that have a high aperture, and a high aperture allows more light to enter the lens when shooting and then reach the sensor.
As you know, the aperture value of a lens is It is measured with f-stop, and the lower the f-stop number, the wider the aperture. For night photography, lenses with f/2.8 or lower are ideal.

6. Use a high ISO (though not too high)
The "ISO" number indicates the sensitivity of the camera sensor to light and ultimately affects the brightness of the final image. In fact, using a lower ISO when shooting means a darker photo, and using a higher ISO when shooting means a brighter photo.
Reading this sentence may make you think of setting the ISO to the highest The mode is very suitable for photography, but we must say that doing so causes the final photo to have a lot of noise and grains. You can set the ISO value to 6400 when shooting, but the safer choice is to set your camera ISO between 1600 and 3200.
7. Use Rule 500 to Determine Exposure Time
Exposure time indicates how open the camera shutter is, or shutter speed. Rule 500 determines how long the camera shutter must stay open before celestial objects move in the final image. Moving celestial objects and recording them in motion in the image causes the final image to have a star-like phenomenon, which is not the subject of this article.
Now back to Rule 500, Rule 500 tells us that the number 500 Divide the focal length of your lens. The number obtained from this division tells you how long your camera shutter should stay open. For example, if you use a lens with a focal length of 14 mm when shooting, you should leave your camera shutter open for 36 seconds (500 divided by 14 equals 35.7).
If you use a crop sensor camera instead of a full-frame camera, you should use Rule 300 instead of Rule 500. In fact, at this point you should divide the number 300 by the focal length of your lens.
The longer the shutter is open, the more light enters the camera and reaches the sensor. This happens to allow you to reduce the camera's ISO number, which makes the final image less noisy. Of course, you have to keep in mind that the 500 or 300 rule is flexible. In fact, these two rules try to give you an overall estimate of the amount of shutter speed to prevent the movement of celestial bodies in the final photo.

8. Secure the camera yourself
The requirement to use a slow shutter speed is to keep your camera steady the entire time the shutter is open, as the slightest movement when the shutter is open causes the final image to be blurred. Let the water come. With this in mind, using a tripod when using low shutter speeds is critical. In fact, the tripod is a vital tool for shooting in low light.
We also recommend that you take the remote control to activate the camera shutter when shooting in low light. These remotes are usually cheap and you can get the perfect remote control for your camera from a variety of cordless and cordless remotes. Using the remote control eliminates camera shake when shooting so that the camera does not have any vibration when shooting.
Shoot at night
For night and low light shooting It is necessary to apply special settings in the camera that allow as much light as possible to enter the camera and reach the sensor. You may not be able to take beautiful photos in your first attempts at this style of photography, but practicing and repetitioning will allow you to quickly learn how to set up your camera in the best possible way for night photography.
These are all tips you need to try out astronomical landscape photography, and you can definitely use these tips to capture spectacular photos.
