![]() This drastically affects your image quality. ConsiderationsĪ higher ISO results in grain, or noise, showing up on your photo. In almost all other styles of photography, especially landscapes, you want your ISO to be as low as possible. That’s why you want to turn your ISO up high. When you’re taking a photo of the night sky, you want your image to be bright. In the most basic terms, ISO affects how sensitive your camera sensor is to light, which directly affects the brightness of an image.Ī low ISO (such as 100) means that the sensor isn’t very sensitive to light, and will result in a darker image, depending on your camera settings.Ī high ISO (such as 3200) will make your sensor more sensitive to light, and will result in a brighter image. “What ISO should I use for night sky photography?” How long your shutter speed can stay open without seeing any star trails is directly related to your focal length, which we dive into below under ‘The 500 Rule’.īut for beginners just remember that as long as you’re using a wide angle lens, somewhere around 25 seconds as a shutter speed will be fine.Ī slow shutter speed allows you to capture the core of the Milky Way when there is no light pollution. That’s why you use a tripod.Ī slow shutter speed can also result in faint (or large) star trails thanks to the earth rotating. While your shutter is open your camera needs to be perfectly still so you don’t introduce any motion blur to scene. This gives ample time for the stars to show up on your photo. The longer your shutter is open, the more time the faint light from the stars has to embed itself on your image.įor the purpose of night sky astrophotography, aim to have your shutter open for around 25 seconds to start with. It also has other effects on photography, such as the ability to introduce motion blur, but for astrophotography settings we’re going to focus on the light side of things. Shutter speed is how long the shutter on your camera remains open, which directly affects how long light is being registered on your sensor. Something to remember.Ī wide aperture allows you to let as much light as possible hit your sensor. That means when you focus on the stars, the foreground will be a little bit blurry. When you’re shooting at a wide aperture the depth of field is going to be very narrow. Great astrophotography lenses will be able to open up as wide as f/2.8, or even wider (f/1.8, f/1.4, etc). So you need to help the camera get the most light available by making the aperture as wide open as possible. That last part is very important to learn about, but for now we’ll talk about the light side of things.īecause you need to be shooting astrophotography when it is dark outside, there isn’t much light available for the sensor to read. Wide aperture = shallow depth of field.The smaller the opening is, the less light comes through.īesides the amount of light it lets in, it also affects the depth of field of the image. The wider, or larger, the opening is, the more light can come through and hit the sensor. In basic terms, aperture is the opening at the front of the lens that lets in light.
