NiSi Filter Natural Night 150x150mm

NiSi Filter Natural Night 150x150mm – Blocks common light pollution wavelengths for cleaner night and astrophotography colors

Night photography and astrophotography face unwanted light from mercury vapor, sodium, and low CRI LED streetlights. These sources emit specific wavelengths that pollute the night sky and create a glow that prevents your camera from capturing true sky tones. The NiSi Natural Night Filter reduces those problematic wavelengths so you get cleaner, more natural colors in night images.

Designed for night scenes and astrophotography

Use this filter when shooting night scenes or the night sky. It targets the most common wavelengths of artificial light pollution, helping your camera resolve stars and sky tones with less contamination from streetlights. Consequently, you will notice improved color fidelity in long exposures and night compositions.

High-quality optical glass for modern cameras

The filter is made from precision annealed optical glass. Its surface is finely ground and polished to preserve sharpness, specifically for today's ultra high megapixel cameras. In short, the glass construction supports high-definition imaging without introducing softness.

Advanced NANO Coating to reduce reflections

NiSi applies its NANO Coating technology to the Natural Night Filter. This multi-layer coating minimizes surface reflections and so helps reduce ghosting and flare in night shots. At the same time, the coating is engineered to avoid introducing a color shift or any loss in sharpness.

Durable protective surface

The filter includes a protective coating that repels water, dust, and oil. Because of this layer, you can wipe moisture and contaminants off the glass more easily without worrying about scratching the surface. This makes field cleaning faster and safer for the optical finish.

FAQ

Question: What kinds of light pollution does the NiSi Natural Night filter block?
Answer: The filter blocks the most common wavelengths emitted by typical light pollution sources such as mercury vapor, sodium, and low CRI LED streetlights, helping reduce glow that affects night images.

Question: Will the filter affect image sharpness or color balance?
Answer: NiSi states that the NANO Coating achieves reduced reflections without causing a color shift or loss in sharpness, and the precision annealed optical glass is finished to preserve high-definition detail for ultra high megapixel cameras.

Question: Which sizes are available and how do I choose?
Answer: The Natural Night filter is available in 100*100 and 150*150mm sizes. Choose the size that fits your filter holder system and the format you use for night or astrophotography shooting.

Question: How should I clean the filter in the field?
Answer: The filter includes a protective waterproof and oil resistant layer that makes it easier to wipe off water, dust, and oil. Because of this protective coating, you can clean the surface more safely without worrying about scratching the glass; still, use gentle cleaning tools and practices for best results.
