Getting sharp photos of stars in astrophotography can be quite challenging. But without any fuss, below are some professional tips and techniques to help you achieve the best results:
Use a sturdy tripod:
In astrophotography, a sturdy tripod is essential for preventing camera shake and ensuring that your camera remains stable during long exposures. Make sure you set your tripod on stable ground and use a remote or cable release to trigger the camera without physically touching it. This way, you can prevent your starry images from becoming blurred.
Focus manually:
Next, we suggest you use manual focus if you want to capture the night stars. Your camera’s autofocus system might struggle in low-light conditions. So, you should focus on the stars manually. Focus on a particular bright star or use a live view to zoom in and adjust the focus manually until the stars appear sharp.
Shoot the stars with a fast aperture:
Furthermore, we recommend you shoot the stars with a faster aperture, such as f/2.8 or f/1.4. This will allow more light into your camera and help reduce the need for longer exposure times. This can also help you reduce the risk of having star trails or streaks in your photos.
Use a shorter shutter speed:
Generally, long exposure times can make your photographs appear blurry due to the earth’s rotation. So, we suggest you use a shorter shutter speed or a star tracker to keep your camera pointed at the stars and avoid star trails.
Use a lower ISO setting:
Higher ISO values (800+) can introduce noise and degrade the quality of your images. So, use the lowest ISO possible while still capturing enough light for your desired exposure. Ensure you try different ISO settings to avoid overexposing or underexposing the stars.
Consider stacking images:
Stacking multiple images can help reduce noise and improve overall sharpness. You can use specialized software to align and stack your star images taken with the same settings. Some of the best image-stacking software include:
- Helicon
- Zerene Stacker
- Affinity Photos, etc.
Use a high-quality lens:
Use a high-quality lens to get sharp stars in astrophotography. A high-quality lens, like the AF-S NIKKOR 14-24mm f/2.8G ED, can make a significant difference in the sharpness of your images. We recommend you use lenses with low chromatic aberration and good sharpness at wider apertures for night star photography.

Use a high-quality camera:
In addition to using a high-quality lens, you must also use a high-grade camera for astrophotography. Generally, we recommend using cameras specially designed for the genre. However, you may use any DSLR or mirrorless camera with a larger sensor size and the ability to render great results in low light.
By practicing:
Finally, to get sharp stars in astrophotography, you must always engage in steady practice and shooting. You have to dedicate a reasonable amount of your time to clicking photos of the stars every night. Realistically, it is not enough to have a high-quality camera and lens or know how to optimize them. You must be consistent and dedicated to the course if you want your pictures to always appear sharper.
In conclusion, by following these tips, you can improve the sharpness of your stars in astrophotography and also capture stunning photographs of other objects in the night sky.
