NiSi Natural Night Filter – Blocks common light pollution wavelengths for cleaner night scenes and astrophotography

The NiSi Natural Night Filter reduces the glow from common urban light sources so your camera can capture the night sky with cleaner, more accurate colors. It targets wavelengths produced by typical streetlights and other sources of light pollution to improve night and astrophotography results.

Designed to combat common light pollution sources

Between mercury vapor, sodium, and low CRI LED streetlights, many undesirable wavelengths of light can pollute the night sky. These glows often prevent your camera from seeing faint stars and subtle sky colors. The NiSi Natural Night Filter blocks those most common wavelengths, which helps you achieve cleaner skies and nicer colors in your night images.

High-quality optical glass and precise finishing

NiSi makes this filter from precision annealed optical glass. Its surface is finely ground and polished to maintain sharpness, even with today’s ultra high megapixel cameras. In other words, the filter preserves image clarity while you reduce unwanted light pollution.

NANO Coating for low reflection and easy cleaning

The filter features NiSi’s unique NANO Coating technology. This multi-layer coating reduces surface reflections to help prevent ghosting and flare. In addition, the coating includes a protective layer that makes it easier to wipe off water, dust, and oil without worrying about scratching the glass. Importantly, the NANO Coating achieves these benefits without introducing a color shift or any loss in sharpness.

FAQ

question: Will this filter help when shooting in cities with many streetlights?
Answer: Yes. The NiSi Natural Night Filter blocks the most common wavelengths emitted by mercury vapor, sodium, and low CRI LED streetlights, which helps reduce the urban glow that can wash out night sky details.

question: Does the coating affect image sharpness or color balance?
Answer: No. The NANO Coating reduces reflections and protects the glass without causing a color shift or loss in sharpness, so your images remain accurate and detailed.

question: How does the filter hold up to cleaning and outdoor use?
Answer: The filter uses multi-layer, double sided coatings that are waterproof and oil resistant. The protective top layer makes it easier to wipe off water, dust, and oil while minimizing the risk of scratching the glass.

question: Which camera systems is this filter suitable for?
Answer: The NiSi Natural Night Filter is designed to work with lenses that accept circular filters in the available sizes, and its high-definition optical glass and polished surface keep sharpness suitable for ultra high megapixel cameras.
