NiSi 95mm Natural Night Filter (Light Pollution Filter)

The NiSi 95mm Natural Night Filter is specifically designed for night sky and astrophotography to reduce light pollution from urban areas and artificial lighting sources. Constructed from high-quality optical glass with precision annealing and a finely ground polished surface, this filter delivers exceptional clarity and sharpness for ultra-high megapixel cameras. The advanced nano coating technology provides waterproof, oleophobic, and scratch-resistant performance whilst reducing reflection to minimise ghosting and flare. With approximately 1-stop light reduction, the filter selectively blocks the dominant wavelengths of light emitted by sodium-vapor lamps, mercury-vapor lamps, and low CRI LEDs-all common sources of urban light pollution. An aluminium-alloy filter ring ensures durability and secure fitting on any 95mm threaded lens.
