NiSi 55mm Natural Night Filter (Light Pollution Filter)

The NiSi 55mm Natural Night Filter is purpose-built for night photography and astrophotography, designed to reduce the appearance of light pollution in images featuring the night sky and artificial light sources. Crafted from high-quality, precision annealed optical glass with NiSi's signature NANO Coating technology, this filter blocks unwanted wavelengths from common sources of light pollution such as mercury vapour, sodium, and low CRI streetlights. With approximately 1 stop of light reduction, the filter preserves image brightness and detail whilst enhancing contrast in your nighttime shots. The double-sided multi-layer nano coating reduces reflections to help minimise ghosting and flare, while also offering waterproof and oil-resistant properties for easy maintenance. The finely ground and polished surface ensures sharpness for today's ultra-high megapixel cameras.
