Product Information

Full details

The Cokin 77mm Nuances Clearsky Filter is an essential tool for landscape, cityscape, and astrophotographers who struggle with urban light pollution. By selectively blocking the wavelengths emitted by sodium and mercury vapor lamps, this filter restores natural color balance and enhances contrast in night sky imagery. While it is highly effective at reducing orange and yellow color casts in city environments, users should note that it may require slight adjustments to white balance during post-processing to achieve the perfect aesthetic for their specific scene.

FAQs

Does this filter work for daytime photography?

This filter is optimized for night photography to combat artificial light. Using it during the day may result in unnatural color shifts.

Can I stack this filter with other filters?

Yes, you can stack filters, but be mindful of potential vignetting, especially if using a wide-angle lens.

Is this filter weather-sealed?

It features AF coatings that provide resistance to water and oil, but it should not be submerged in water.

Will this filter help if I am in total darkness?

No, the filter specifically targets artificial light pollution. In areas with zero light pollution, it will have minimal impact on your imagery.

How do I clean the filter safely?

Use a dry, clean microfiber cloth to wipe away dust or smudges. For stubborn spots, use a small amount of photographic lens cleaning fluid on a cloth.

Troubleshooting

Difficulty threading onto the lens

Ensure the lens threads and the filter threads are clean and free of debris. Gently rotate counter-clockwise until you feel the thread catch before tightening.

Image appears too cool or shifted in color

The filter effectively cuts orange/yellow light, which can shift the white balance. Adjust your camera's white balance settings or compensate during post-processing to restore the desired warmth.

Pros and Cons

Pros

  • Significantly reduces orange and yellow light pollution glows
  • Enhances contrast and detail in stars and the Milky Way
  • High-quality neodymium glass ensures excellent optical performance
  • Protective coatings simplify cleaning in humid or dusty environments

Cons

  • Requires manual white balance adjustment for optimal color rendering
  • Not intended for daytime landscape use due to color filtering properties
  • Requires specific 77mm lens thread compatibility

Setup, Compatibility & Care

The Cokin 77mm Nuances Clearsky Filter is designed for lenses with a 77mm filter thread. To install, gently screw the filter onto the front element of your lens until finger-tight; do not overtighten, as this can make removal difficult in cold weather.

For maintenance, use a high-quality lens pen or a microfiber cloth to remove smudges. Because the filter features specialized anti-reflective and protective coatings, avoid using harsh chemicals or abrasive materials. Always store the filter in its protective case when not in use to prevent scratching the glass surface during transport.
