FAQ about light pollution filters for astrophotography

Why do I need Astro filters for astrophotography?

When photographing celestial objects or night sky in the city or not far away, you will face the problem of light pollution. The impact of artificial light doesn’t allow for capturing clear images with true-to-life colours, adding an orange glow to them instead. Astro filters reduce light pollution and enhance image quality and contrast, increasing detail in captured photos. They help to eliminate unwanted glare and atmospheric distortion, allowing you to capture sharper, clearer images of stars, galaxies, and nebulae.

How do Astro Filters work?

Astro filters selectively filter out specific wavelengths of light, such as those emitted by artificial sources like streetlights or urban areas. Our Kase neutral night filters, for instance, are designed to block out unwanted light pollution while preserving the natural colours of the night sky. Simply saying, they reduce the orange sodium glow coming from artificial light. This enables your camera to capture night photos with greater clarity and more details.

Can I use Astro filters when photographing night cityscapes?

Of course! While Astro filters are primarily designed for astrophotography, they can also be used to enhance night cityscape photography by reducing the effects of light pollution and enhancing contrast. Just keep in mind that depending on the specific filter and lighting conditions, you may need to adjust your exposure settings accordingly to achieve the desired results.

Is it possible to replicate the effect of light pollution filters for astrophotography in post-processing?

While some aspects of the Astro Filter's effects, such as reducing orange glow and enhancing contrast, can be replicated to some extent in post-processing, the results may not be as precise as using a physical filter during the image capture process. Astro filters can also help to keep more detail of the original scene on the image, which is not something you can reach with post-correction.

How do I clean and maintain my Astro filters?

We recommend gently cleaning your Astro Filters using a soft microfiber cloth and a mild cleaning solution designed specifically for camera lenses (if needed). Avoid using harsh chemicals or abrasive materials that may scratch or damage the filter surface. Check out our article to see the detailed instructions for cleaning camera filters.
