A Digital single-lens reflex (DSLR) camera is one of the best tools for astrophotography. DSLRs have larger image sensors, and their ability to thrive in low light makes them ideal for capturing sharp and well-detailed images of the sky at night.

However, using any type of DSLR camera for astrophotography can be challenging, especially for beginners. Thus, we have gathered professional tips and tricks in this article to help you capture high-quality sky images with any mid-level or high-grade DSLR camera.
Choose a suitable DSLR camera:
Firstly, choose a DSLR camera with intuitive controls, a long-lasting battery, and a large image sensor. The bigger the sensor size, the better the camera for astrophotography.
Choose the right camera lens:
Next, get a good compatible lens for your DSLR. For astrophotography, we recommend a wide-angle lens with a fast maximum aperture, such as f/2.8 or even wider.
Find a dark location in your area:
Then find a good location with less to no light pollution. Excessive light can affect the overall look of your night sky and star images. So try to find a safe place from city lights. You can find a dark spot in your area with the aid of Darksitefinder. Do not forget to check the weather forecast too. Ensure the weather condition is good and the sky is clear before leaving your home.
Use a sturdy tripod and remote shutter release:
You will need a sturdy tripod to stabilize your camera and prevent any form of camera movement during long exposures. A tripod is an important piece of equipment for astrophotography – whether you want to capture the Milky Way or the plain night sky.
Similarly, you will need a remote shutter release to avoid touching the camera when you are ready to click. Manually clicking the shutter might cause a shake, and this can result in blurry pictures.
Set up your DSLR camera:
Optimize your DSLR camera for shooting. We recommend the following settings:
- A high ISO range between 400 to 3200 (or even higher). But be mindful of image noise.
- Use manual focus
- Set your aperture widest (preferably f/2.8)
- Set the white balance to “auto” or “daylight”
- Set your shutter speed to a long exposure time, preferably between 15 and 30 seconds
- Shoot in RAW image format
- Focus on infinity
Note: The end product of this camera setting will depend on your location, the lighting situation, and the object you want to capture. You may start with the recommended camera setting and adjust your camera accordingly after taking a few test shots. Do not be afraid to experiment with different settings. Try different ISO settings, exposure times, and compositions to find the best settings for your particular location, subject and desired effects.
