Home Filters Light Pollution Filters Vaonis Vespera Light Pollution CLS Filter
The Vespera light pollution or CLS (City Light Suppression) filter improves the quality of your photos when observing in the city or suburbs.It attenuates the effects of light pollution and thus increases the contrast between the celestial object being photographed and the background sky.The broadband filter blocks wavelengths mainly emitted by urban night lighting or undesirable natural light while allowing the main wavelengths from celestial objects.Essential for observing from an environment where light pollution is very present (urban and peri-urban environment, residential lighting, etc.).Improves the quality and brightness of deep sky objects, like nebulae, galaxies and star clusters. It is especially effective when photographing emission nebulae.
