DarkSky Finder and Descriptions

The DarkSky Movement is a campaign to help stop light pollution. Rural areas and areas far from the skyglow of cities have darker skies than cities do. These dark country and rural skies are not pollution by light, which makes more constellations such as the Milky Way and Zodiacal light more visible to the naked eye. The closer you are to a city, the more affected night skies are going to be; the more light that is polluted into night skies, less constellations are visible. The DarkSky Movement's campaign is, in short, trying to make constellations visible more places by reducing light pollution. The DarkSky Movement's website lists areas were dark skies are available and includes a map. There is also a description of sky features to help identify and classify the amount of light polluted in an area at night.
