NiSi 150x150mm Natural Night Filter (Light Pollution Filter)

The NiSi 150x150mm Natural Night Filter is purpose-designed for night photography and astrophotography, blocking the most common wavelengths of light pollution from artificial sources. Crafted from high-quality precision-annealed optical glass with NiSi's signature NANO Coating technology, this filter features a finely ground and polished surface that ensures exceptional sharpness even with ultra-high megapixel cameras. The multi-layer nano coating provides waterproof and oil-resistant protection, reduces reflections to minimise ghosting and flare, and makes the filter easy to clean. Compatible with any 150mm square filter system including NiSi S5 and S6 holders, this filter is essential for capturing pristine night skies free from colour distortion caused by sodium-vapour lamps, mercury-vapour lamps, and low CRI streetlights.
