Correct Colour Distortion

The 75 x 80mm Natural Night Light Pollution Filter from NiSi is a must-have for night scenes and astrophotography. Light pollution is a problem in areas near intense sources of artificial light, like cities. This filter helps fix colour distortion caused by the yellow light frequencies of mercury vapour, sodium, low CRI streetlights and more. These sources can stop your camera from capturing the sky accurately, impacting your astrophotography and night images. Natural Night Filters block the most common wavelengths of light pollution, giving you neutral, natural tones.

Made of high-quality, precision annealed, finely-ground and polished optical glass, this filter features NiSi's unique NANO Coating technology. This multilayered coating reduces reflection on the surface of the filter to help with ghosting and flare. There is also a resistance coating that protects against scratches and abrasions while making it easy to wipe off water, dust, and oil.

This 75 x 80mm filter is compatible with the NiSi 75mm filter system, and other filter holders that accept filters measuring 75mm wide and 2mm thick.
