Vaonis Vespera CLS Filter

With the Vespera light pollution filter or CLS filter (City Light Suppression), you can improve the quality of your photos when observing in the city or suburbs.

Improves the quality of nebula photography

The broadband filter blocks wavelengths of Na (sodium) and Hg (mercury) emitted mainly from urban night lighting or unwanted natural light (atmospheric oxygen radiation, etc.), while blocking wavelengths of Hg (mercury

) emitted from the sky.

The light pollution filter is particularly useful for enhancing the brightness of deep-sky objects
