night skies at McDonald Observatory
Bill Wren, ambassador of the dark sky movement, gives us a tour around McDonald Observatory
This past February marked a tremendous gain by advocates against light pollution in West Texas when Big Bend National Park was designated as an International Dark Sky Park. This designation means that the skies above the park are free from all but minor forms of light pollution. 

This feat was accomplished in no small part by advocate and ambassador of the dark sky movement, Bill Wren. Wren, an astronomer at McDonald Observatory, works tirelessly educating businesses, officials, and individuals about the preservation of our skies. In short, less is more. Shielding light fixtures, reducing intensity, and directing the source downward saves money, improves visibility, and enhances safety.

By taking small steps, the movement is making a big difference. In West Texas, ongoing outreach efforts teach individuals about the importance of protecting the night sky. 
Directional light sources enhance safety while preserving the beauty of the night sky.
Directional lighting on timers also provide businesses with reduced costs.
