NiSi Filter Natural Night 55mm

NiSi Filter Natural Night 55mm – Reduces light pollution for night scenes & astrophotography

Use the NiSi Natural Night 55mm filter when you photograph night scenes or do astrophotography. It blocks the most common wavelengths from light pollution so your camera captures cleaner, more natural colors in the sky.

Designed to reduce light pollution in night photography

Streetlights such as mercury vapor, sodium, and some low CRI LEDs emit undesirable wavelengths that create a glow in the night sky. This glow can prevent your camera from seeing the sky properly and can ruin night images. The NiSi Natural Night filter blocks those common wavelengths of light pollution, helping you record clearer skies and improved color rendition in your photos.

High-quality optical glass for sharp images

NiSi makes this filter from precision annealed optical glass. The surface is finely ground and polished to preserve sharpness for today's ultra-high-megapixel cameras. As a result, the filter supports detailed capture without introducing softness.

Advanced NANO Coating to reduce reflections and protect the surface

The NiSi Natural Night Filter features NiSi's NANO Coating technology. This multi-layer coating reduces reflection on the filter surface to help control ghosting and flare. In addition, the coating includes a protective layer that makes it easy to wipe off water, dust and oil from the filter without worrying about scratching the glass. Importantly, the NANO Coating achieves these benefits without causing a color shift or any loss in sharpness.
