NiSi Filter Natural Night 100x100mm – Blocks Light Pollution for Night Scenes and Astrophotography

Streetlights such as mercury vapor, sodium lamps, and some low CRI LED fixtures emit unwanted wavelengths that pollute the night sky. These wavelengths create a glow that can prevent your camera from capturing clear night scenes and astrophotography. The NiSi Natural Night filter blocks the most common wavelengths of light pollution so you get cleaner and more natural colors in your images.

Designed for night scenes and astrophotography

Use this filter when shooting city nightscapes or the night sky. It targets the common sources of light pollution mentioned above and helps your camera see the sky more clearly. As a result, you can capture improved color fidelity in nocturnal landscapes and star fields without introducing color shifts.

High-quality optical glass and surface finish

NiSi manufactures the Natural Night filter from precision annealed optical glass. The surface is finely ground and polished to meet the demands of today’s ultra high megapixel cameras. This fabrication preserves image sharpness across the frame while remaining suitable for modern sensors.

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 allows you to wipe away water, dust, and oil without worrying about scratching the glass. Importantly, the NANO Coating achieves these surface protections without causing color shift or loss of sharpness.

How it benefits your workflow

The Natural Night filter reduces unwanted color casts from common urban light sources, so you can spend less time correcting color in post-production. Because it maintains sharpness and avoids color shift, you can rely on the filter to preserve image quality for prints, galleries, or high-resolution deliveries.
