NiSi Filter Natural Night 75X80mm

NiSi Filter Natural Night 75X80mm – Blocks common light-pollution wavelengths for night scenes and astrophotography

This NiSi Natural Night filter reduces the impact of common light-pollution wavelengths so your camera can capture cleaner night scenes and better astrophotography. It targets glow from mercury vapor, sodium, and low-CRI LED streetlights that often contaminate the night sky. By blocking those undesirable wavelengths, the filter helps deliver nicer and more accurate colors in nighttime images.

Purpose and use cases

Use this filter for night scenes and astrophotography. It works where artificial lighting—such as mercury vapor, sodium lamps, and low-CRI LEDs—casts unwanted color and glow across the sky. Therefore, you can shoot night landscapes, cityscapes, and star fields with reduced color contamination from common street lighting.

Optical quality and manufacturing

NiSi manufactures the Natural Night filter from precision annealed optical glass. Its surface is finely ground and polished to preserve sharpness for today’s ultra high-megapixel cameras. In short, the filter maintains image clarity while handling demanding resolution needs.

Coating, reflection control and protection

The filter features NiSi’s NANO Coating technology. This multi-layer coating reduces surface reflections to help limit ghosting and flare in night images. Additionally, NiSi adds a protective layer that 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 introducing a color shift or loss in sharpness, preserving the natural look of your night photos.
