The best light pollution filters help you achieve the best results when shooting astrophotography. But which light pollution filter do you need? You need one that fits your camera. The filter has to meet your experience level, whether you’re a beginner, intermediate, or pro. And finding a good filter within your budget is always important.
We’ve got a wide range of light pollution filters in our article. But the K&F Concept Clear Natural Light Filter is the best of the bunch. The optical quality is fantastic, improving image quality in several ways. It’s a well-made lens accessory. And it’s available in different sizes. It’s a brilliant filter for astrophotography.
What Is the Best Light Pollution Filter?
The best light pollution filter gives you clearer and sharper results for astrophotography and Milky Way photography, especially when shooting from urban areas. They block out artificial light, letting stars and galaxies shine brighter in the night sky.
Light pollution filters are also known as natural light or neutral light filters. Some manufacturers also label them night light light filters. And there are several different types of light pollution filters.
First, you have circular filters that screw directly onto the front of your camera lens. The key here is finding a filter that fits your astrophotography camera lens. You need the specific filter that fits your lens. But thankfully, most of the circular filters on our list have different size options.
You also get square and rectangular filters. These come in generic sizes. And you mount them in front of your camera lens. You need a special filter holder to mount the filter. Veteran filter users might have a mount system already. But some filters come with mounts and holders included.
For certain camera brands, you can also get clip-in light pollution filters. Two are featured on our list. And they clip into your camera, sitting in front of the sensor.
You don’t attach them to the lens as with circular filters. They are only compatible with specific types of cameras. But the positive is you don’t need a different size filter for each lens.
Here’s a quick overview of all the best light pollution filters we’ve rounded up. We look at each filter in more detail in the section after. And we have a FAQ section at the end if you need more information on light pollution filters.

FAQs About the Best Light Pollution Filters
Light pollution filters can be tricky, especially if you don’t have much experience with camera filters. That’s why we’ve answered some of the most frequently asked questions. We hope this helps you find what you need.
What Do Light Pollution Filters Do?
Light pollution filters block certain light from passing through the filter into the camera. It mainly blocks artificial light and allows natural light to pass through. That means stars and other astrological objects show more clearly in your images.
Milky Way photography and astrophotography aren’t easy disciplines. And achieving optimal results is even more difficult if you’re shooting from a built-up urban area.
Streetlights and other artificial light sources create light pollution, obscuring your view of the stars. That’s why you don’t see many stars when you look up from a city. Even on a clear night, you’ll be lucky to glimpse just a handful of stars.
Light pollution filters block out the noise and allow you to see the night sky more clearly. They do this by blocking specific wavelengths of light.
Artificial light sources usually emit light from the yellow and orange areas of the visible light spectrum. Therefore, these filters block light waves from those areas of the spectrum while letting other light waves pass through.
These light pollution filters sit in the category of broadband light filters. That’s because they allow a broad section of the light spectrum through while only blocking a narrow portion. This means they reduce light pollution without dramatically reducing the color range in your night sky images.
Are Light Pollution Filters Only for Astrophotography?
Light pollution filters are most commonly used for astrophotography and Milky Way photography. But you can also use them for different types of photography. They are a great tool for nighttime cityscape photography.
Cityscapes often appear orange or yellow, and the glow can create a haze. A light pollution filter blocks the wavelengths from the yellow end of the light spectrum. This reduces the orange glow and sharpens light sources in the image. You get a clearer and sharper image.
You can also use neutral light filters for nighttime landscape photography. When you light a landscape artificially at night, the image is usually dominated by yellow and orange tones. The filter removes the yellow and orange tones, giving you a cleaner and whiter light. Your scene will look more naturally moonlit.
What Other Astrophotography Filters Are There?
There are many other types of filters astrophotographers use, and we list four below. To learn more, you can read our full article on the best astrophotography filters.
1. Narrowband Filters (UHC Filters)
We’ve seen that light pollution filters are a type of broadband filter. But astrophotographers also use narrowband or UHC filters. These work the opposite way, allowing only a narrow bandwidth of light. They transmit the main emission bands from nebulae while blocking all other light.
These are great for capturing deep-space images in pinpoint detail. And if that’s the type of filter you’re after, we recommend the Optolong EOS-C L-Enhance Dual Narrowband Filter. It’s a clip-in filter for Canon cameras.
2. Line Filters
Line filters are even more selective than narrowband filters. They are sensitive to only one emission line from the light spectrum. While UHC filters can be dual, tri, or quad-band, a line filter only transmits one band. We recommend the SVBONY H-Alpha Clip-in EOS-C filter.
3. Diffusion and UV Filters
Diffusion and UV filters are also useful for nighttime photography. They aren’t really used for deep-space photography. But they reduce noise and artificial light pollution when shooting at night. The Tiffen Diffusion Filter is a great option.
4. Solar Filters
Solar filters are also used to take pictures of the sun. You should never attempt to take a picture of the sun without a solar filter. Without one, you’ll break your camera sensor and blind yourself. The Thousand Oaks Polymer Solar Filter is your best option to capture the next solar eclipse.
What Camera Settings Do I Use With a Light Pollution Filter?
When taking pictures with a light pollution filter, there’s only one camera setting you need to worry about. And that setting is white balance. By reducing the bandwidth of light entering the camera, you must re-calibrate the white balance to ensure you still get true-to-life images.
Switch to manual if you’re using auto white balance (AWB). Every camera is different. That’s why different settings will work for different photographers. But somewhere between 700K and 1500K will give you the best results. Do a few test shots to find out what works. Make a note so you know for future shoots.
Always focus on infinity, especially if you’re using a clip-in filter. And you should also use a wide aperture on your lens. The max aperture isn’t always the best because you might get distortion at the edges. But you can drop one stop down for great results.
What Camera Equipment Do I Need With a Light Pollution Filter?
You always need a photography tripod when shooting the night sky. Light is limited, so you must work with slow shutter speeds or bulb mode. A shutter remote is also helpful in reducing camera movement completely.
Cameras with composite or high-resolution shot modes are great for astrophotography. The Olympus OM System OM-1 and the Fujifilm X-T5 have high-res modes that give you incredibly detailed images. If your camera doesn’t have this mode, you can create multi-exposure composites using photo editing software.
Conclusion: The Best Light Pollution Filter
If you’re in an urban area, street lights, and other light sources cause so much pollution it’s impossible to see the stars above. That’s why a light pollution filter is essential for anyone shooting the sky at night. It’s a must-have in your astrophotography tool kit. And you’ll definitely get better clarity and sharpness in your night sky images.
The K&F Concept Clear Natural Light Filter is the best light pollution filter. It’s available in many different sizes. The optical quality is exceptional. And the multi-layer coatings improve picture quality and protect the glass from wear and tear. It’s well worth the cost if you’re serious about nighttime photography.
