NiSi Filter Natural Night 46mm

NiSi Filter Natural Night 46mm – Blocks common light pollution wavelengths for cleaner night and astrophotography images

This NiSi Natural Night 46mm filter reduces the unwanted glow from common urban light sources so your camera captures cleaner colors in night scenes and astrophotography. It specifically targets wavelengths from common sources of light pollution, helping the sky appear clearer in your photos.

Why use the Natural Night filter?

Night scenes and astrophotography often suffer from light pollution caused by mercury vapor, sodium, and low CRI LED streetlights. These sources produce undesirable wavelengths that create a glow and mask faint sky details. By blocking those wavelengths, the NiSi Natural Night filter helps your camera see the sky more accurately and preserves nicer, more natural colors in your images.

Optical quality and construction

NiSi manufactures this filter from high quality, precision annealed optical glass. In addition, the surface is finely ground and polished to ensure sharpness for today’s ultra high megapixel cameras. Therefore, you retain image detail while reducing unwanted light pollution effects.

NANO Coating benefits

The filter features NiSi’s unique NANO Coating technology. This multi-layer coating reduces surface reflections, which helps minimize ghosting and flare. Furthermore, 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 protective and anti-reflective properties without introducing a color shift or loss in sharpness.

Care and handling

The protective NANO coating makes cleaning straightforward. You can wipe off water, dust and oil without worrying about scratching the glass, thanks to the coating’s protective layer. Still, handle the filter carefully and follow standard cleaning practices for camera optics.

Smart FAQ

Question: Will this filter improve my astrophotography in urban areas?
Answer: Yes. The filter blocks wavelengths from common urban light sources such as mercury vapor, sodium, and low CRI LED streetlights, which reduces the glow that can obscure faint sky details and results in cleaner colors.

Question: Does the NANO Coating affect image sharpness or color?
Answer: No. The NANO Coating reduces reflections and helps prevent ghosting and flare while achieving this without introducing a color shift or loss in sharpness.

Question: What sizes are available and is 46mm included?
Answer: The filter is available as a circular filter in sizes from 40,5 up to 95mm; the listed model here is the 46mm size.

Question: How should I clean the filter and will cleaning damage the coating?
Answer: The coating includes a protective layer that makes it easy to wipe off water, dust and oil. When you clean the filter, use proper optical cleaning methods and soft materials to avoid any risk, but the coating is designed to resist scratching during normal cleaning.

Question: Is this filter suitable only for astrophotography?
Answer: No. While designed for astrophotography, the NiSi Natural Night filter also benefits night scenes in urban and suburban environments where common streetlight wavelengths can pollute the sky and alter colors.
