NiSi 67mm Natural Night Filter (Light Pollution Filter)

The NiSi 67mm Natural Night Filter is specifically designed for night photography and astrophotography, engineered to reduce light pollution caused by artificial light sources. This circular filter blocks the most common wavelengths of unwanted light from mercury vapour, sodium, and low CRI streetlights, allowing you to capture stunning nightscapes and star-filled skies with natural colour reproduction and minimal colour cast. Crafted from precision annealed optical glass with a finely ground and polished surface, the filter delivers exceptional sharpness even with today's ultra-high megapixel cameras. NiSi's unique NANO Coating technology features multi-layer coatings that minimise reflection, ghosting, and flare whilst providing hydrophobic and oleophobic properties for easy cleaning and weather resistance.
