NiSi 77mm Natural Night Filter (Light Pollution Filter)
The NiSi 77mm Natural Night Filter is a new addition to the NiSi range, an exclusive for night photography. Between mercury fumes, sodium, and 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 affect 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.
Nano Coating Technology
The NiSi Natural Night Filter features NiSi’s unique Nano Coating technology. This multi-layer coating reduces reflection on the surface of the filter to help with ghosting and flare. It also includes a protective layer that makes it easy to wipe off water, dust, and oil from the filter without worrying about scratching your glass. The Nano Coating process achieves this without loss in sharpness.
