NiSi Filter Natural Night 58mm

NiSi Filter Natural Night 58mm – Blocks common light-pollution wavelengths for cleaner night and astrophotography

The NiSi Natural Night filter targets unwanted wavelengths from common light-pollution sources so your camera can capture clearer night skies. It removes the glow caused by mercury vapor, sodium and low CRI LED streetlights that often pollute night scenes. As a result, you get cleaner and more accurate colors in your night and astrophotography images.

Designed materials and optical quality

NiSi builds this filter from precision annealed optical glass. Its surface is finely ground and polished to maintain sharpness for today's ultra high-megapixel cameras. In other words, the glass and finish help preserve image detail and clarity.

Coating technology and protection

The Natural Night Filter uses NiSi's NANO Coating technology. This multi-layer coating reduces surface reflections, which helps limit ghosting and flare in challenging lighting situations. Additionally, the coating includes a protective layer that makes it easy to wipe off water, dust and oil without worrying about scratching the glass.

Importantly, the NANO Coating process achieves these benefits without causing a color shift or any loss in sharpness. That means you can reduce unwanted light pollution effects while keeping accurate colors and high definition.
