How Many Stars?

Star Count

This important, and fairly easy to perform Star Count project is designed as part of an international scientific study to investigate the visual quality of the nighttime sky and to help assess the national and global extent of atmospheric light pollution. It will also help to evaluate the amount of energy wasted through poor or inappropriate lighting practices.

Teachers, students, youth organizations ( e.g. Cubs, Scouts, Guides etc.) amateur astronomers, science and environmental organizations, and dedicated interested individuals, are all invited to participate.
