FAQs on the Best Astrophotography Lenses
Astrophotography is one of the most complicated disciplines. And finding the best lens for astrophotography isn’t easy. That’s why we’ve answered some of the most frequently asked questions on the topic.
What Type of Lens Is Best for Astrophotography?
Astrophotography is a broad subject. And you can use several types of lenses for different types of astrophotography. But in our list, we’ve gone with wide-angle lenses.
Wide-angle lenses are the best for capturing large sections of the sky above. This is often called Milky Way or night sky photography. That’s because the night sky is the subject of the image. Other types of astrophotography focus on capturing specific celestial objects, like star clusters, nebulae, or planets.
Capturing these deep-space objects isn’t easy. You need a lens with a long focal length, like a telephoto lens. But you also need powerful telescopic equipment. It’s specialist gear that doesn’t come cheap.
That’s why we’ve focused on wide-angle lenses for night sky photography. With the right lens, anyone can try it from their backyard. Deep-space photography is definitely worth it if you have a passion for space and astronomy. But you can ease your way into it with one of the incredible lenses on our list.
Is a Prime or Zoom Lens Better for Astrophotography?
When it comes to prime vs zoom in astrophotography, you have the choice of either. Both have their positives and negatives, which is why we’ve included primes and zooms in this article.
Prime lenses tend to have better image quality. There are fewer moving parts and elements within the lens, meaning there are fewer variables. You’re not changing the trajectory of light by adjusting the focal length. The problem is that you have less versatility. You can’t adjust the composition without moving the camera.
The main positive of using a zoom lens is its versatility. With a changeable focal length, you get a much greater shot variety. And by zooming in, you get closer to distant subjects. A powerful zoom isn’t so important with this type of photography. But it does give you more composition options, especially if you include Earth-bound objects in the foreground.
The downside of a zoom lens is the optical quality. They are more prone to distortion and chromatic aberration at the edges. And this can be a real issue with wide-angle focal lengths. However, this is becoming less and less of a problem with modern lenses. And you won’t experience much distortion with any of the lenses here.
Which Filters Are Best for Astrophotography?
Astrophotographers commonly use filters to enhance their cosmic photography. And there are several types of filters they like to use.
Light pollution filters are the most popular in astrophotography, particularly with night sky photography. They block certain light waves, so light from artificial light sources isn’t transmitted. That means the camera sensor is only picking up the natural light in the sky. You get much more clarity and detail in your Milky Way images.
You can see all the best light pollution filters in our full article.
Standard light pollution filters are also known as broadband filters. That’s because they only block a small spectrum of light waves, allowing a broad range through. But astrophotographers also use narrowband light filters.
Narrowband filters block all but a specific line of the visible light spectrum. Some transmit more than one line, which is why you’ll see dual-, tri-, and quad-band filters. These filters are used to capture deep-space objects like nebulae.
You also have solar filters. These are a very niche tool for photographing solar flares and solar eclipses. You should never point your camera at the sun. It will break your sensor and your eyes. But with a strong solar filter, certain types of solar photography are possible.
There’s a lot of science involved in astro filters. And while we’re not NASA, we do have a more detailed article on the best filters for astrophotography.
What Is the Best Camera for Astrophotography?
There are two types of cameras you can use for astrophotography. There are specialist astro cameras for capturing celestial objects and deep-space phenomena. Or you can use a standard interchangeable lens camera, like a DSLR or mirrorless.
When it comes to Milky Way photography, all you need is a DSLR or mirrorless and a wide-angle lens. That means you can use any half-decent camera to capture the night sky.
But there are a few key features that will help you get the best results. Of course, the better the resolution, the better the detail in the night sky. But image stabilization is also beneficial when shooting the stars, helping you get sharper images in low light.
One special feature to look out for is Pixel Shift or Multi-shot Mode. It’s also sometimes called High-resolution Shot Mode. In this mode, the camera takes several exposures to create one high-resolution image. This is one of the best ways to capture stunning images of the sky at night. And it gives you more detail and definition from smaller cameras.

What Accessories Do I Need for Astrophotography?
You can’t shoot the Milky Way without a tripod. You’ll be shooting at night, so you’ll need to use very slow shutter speeds. And when you’re shooting in bulb mode, you need all the stability you can get.
That’s why a remote shutter release is also essential. In bulb mode, the camera will pick up the slightest movement and ruin your image. A shutter remote allows you to open and close the shutter without touching the camera. That means no unnecessary shakes or bumps.
It gets cold at night, so you won’t regret packing a decent pair of photography gloves in your camera bag. And we recommend a waterproof camera backpack so your gear stays protected against rain, dew, and condensation.
Conclusion: The Best Astrophotography Lenses
If you’re a photographer with a passion for the stars, you need the best lens for astrophotography. While you can get specialist lenses for deep-space photography, we’ve opted for wide-angle lenses for capturing the night sky. We’ve seen some excellent lenses, but they all have wide focal lengths, fast apertures, and brilliant image quality.
The Canon RF 15-35mm f/2.8L IS USM is our favorite lens for shooting the sky at night. It’s a beautiful lens with incredible optical quality. It also has a fast and constant f/2.8 aperture and optical stabilization. It’s the best astro lens if you’re using a Canon mirrorless camera.
