In addition to white balance (WB) and focal length, the ISO setting is another important factor in achieving good astrophotography results. In this article, we will take a look at the best ISO settings for astrophotography. So, keep reading.

ISO stands for International Organization for Standardization, the body responsible for setting standards for camera sensors. In terms of camera setting, ISO refers to the sensitivity of your camera’s sensor to light. The higher your ISO setting, the more sensitive your camera sensor will be to light.
A high ISO setting allows the camera to capture more light and produce brighter images in low light. However, a high ISO value can introduce noise or grain and degrade your astrophotos’ overall look or quality. On the other hand, a lower ISO setting will add little or no grain to your photos. But the images might be underexposed, especially when you are shooting in low light.
Therefore, the best ISO settings for astrophotography will depend on several factors, including your camera, lens, ambient light conditions, and your desired outcome. Typically, we suggest between ISO 800 and ISO 3200. However, the most ideal ISO setting for you will depend on the factors mentioned earlier. Most importantly, it will depend on the lighting conditions in your area.
If you are shooting in dark areas with little light pollution, we recommend you use a higher ISO setting between 1600 and 3200. This will provide more light and make your images brighter. You must keep in mind that higher ISO settings usually introduce noise into images. So, you have to find a balance between your ISO setting and the quality of your image. If you are using a high-grade camera, you can use the “long exposure noise reduction” feature to reduce noise and sustain the quality of your photos.
This might not be necessary if you are shooting in bright light conditions, such as during a full move or in a light-polluted area. In such situations, we recommend starting with a lower ISO setting of 400 to 800 to prevent your images from becoming overexposed. You can adjust the setting accordingly to achieve your desired results.
A lower setting might make your images underexposed, while a higher setting might make the photos noisy and overexposed. So, try to keep it moderate and avoid using extremely higher or lower ISO settings. Generally, there is no specific or one-size-fits-all ISO setting for astrophotography. So, we suggest taking different shots of the night sky with different settings.

There are no specific or best ISO settings for astrophotography. However, we recommend starting with an ISO between 800-3200, especially if you are using a DSLR camera. But this will depend on certain factors like your maximum aperture opening and ambient lighting situation. You can start with a lower ISO setting of 200 or 400 and adjust accordingly to get your desired results.
In conclusion, what ISO setting “you should use for astrophotography” will depend on your camera and lighting conditions. Ultimately, there is no specific or best ISO value for capturing the night sky. So, you should experiment with different ISO settings to find the best one for you.
