NiSi 100x100mm Natural Night Filter (Light Pollution Filter)

The NiSi 100x100mm Natural Night Filter is a new addition to the NiSi range and our first filter exclusive for night photography. Between mercury vapour, sodium, Low CRI streetlights, there are many undesirable wavelengths of light that pollute the night sky. The glow from these can keep your camera from seeing the sky properly and effect your night images. Because of this, NiSi has created the Natural Night Filter to block the most common wavelengths of light pollution. Like the rest of the NiSi line, this filter is made of high quality, precision annealed, optical glass. Its surface is finely ground and polished to ensure sharpness for today's ultra high megapixel cameras.
