Anyone who has tried to use a telescope in the eastern portion of the United States knows how much light pollution there is from cities and large-scale uses such as airports. The glow from these can travel for hundreds of miles and obscure the night sky. Some astronomers have banded together to preserve this important view. They have founded communities in dark sky areas. Using innovative land development techniques they are preserving as much of their dark sky as they can.
Most of these developments have large open fields that they share with the public. For small annual or daily fees, astronomers can observe the night sky and share the fellowship of fellow astronomy enthusiasts.
