COKIN Nuances Clearsky Light Pollution Filter Diameter 95 mm

• Light pollution filters block certain wavelengths of street lighting, such as the emission spectra of sodium and mercury vapour lamps.
• In city photography, the yellow-orange hue of street lamps is greatly reduced.
• In astrophotography, the contrast of the sky is increased by obscuring the gradient of the sky background, causing the stars or the Milky Way to stand out.
• High resolution neodymium doped laser phosphate glass
• Double-sided AR and AF multi-layer optics treatment (anti-glare, water-repellent, oil-resistant and scratch-resistant)

Light pollution filters block certain wavelengths from urban lighting, such as the emission spectrum of sodium and mercury vapour lamps. In urban photography, the yellow-orange shade of the lamps is greatly reduced. In astrophotography, the contrast of the sky is increased by darkening the gradient of the sky bottom, bringing out the stars or the milk way.
