NiSi Filter Natural Night 180x180mm – Blocks common light pollution wavelengths for cleaner night and astrophotography

The NiSi Natural Night filter reduces the impact of common light pollution wavelengths so you capture cleaner colors in night scenes and astrophotography. It targets unwanted emissions from mercury vapor, sodium, and low CRI LED streetlights that often glow and mask details in the night sky.

Key uses

Use this filter for night scenes and astrophotography where artificial light sources affect color and contrast. By blocking the most common wavelengths of light pollution, the filter helps your camera see the sky more clearly and preserves the natural tones in your images.

High-quality optical glass

NiSi manufactures this filter from precision annealed optical glass. Furthermore, the surface is finely ground and polished to maintain sharpness with today’s ultra high megapixel cameras, ensuring image clarity across modern sensors.

NANO Coating and protective layers

The Natural Night filter features NiSi’s NANO Coating technology. This multi-layer coating lowers surface reflections, which helps reduce ghosting and flare. In addition, a protective layer makes it easier to wipe off water, dust, and oil without worrying about scratching the glass.

Importantly, the NANO Coating process achieves these benefits without causing color shift or a loss in sharpness, preserving image fidelity while improving handling and durability.
