In addition to the unrest in the air, the lightening of post-heaven is the greatest obstacle for the observation of light-weaker objects beyond the solar system. Through artificial lighting, the sky in human settlements is no longer properly black. This also affects the contrast and thus the perception of the DeepSky objects.

Depending on the type of the sky object, however, a part of the interfering light can be filtered away, thus facilitating the observation of the objects. The CLS filter is the all-rounder for this application. He uses the fact that the artificial brightening is not evenly distributed over the entire spectrum. These colors - especially the typical colors of street lighting - are suppressed, but the light of the DeepSky objects is left out.

A must for any visual observer.
