After a three-year journey of over 150,000 miles (241,000 km) traveled and 3,000,000 pictures taken, timelapse filmmakers Harun Mehmedinovic and Gavin Heffernan introduce SKYGLOW; a 192-page hardcover photo book and Blu-Ray timelapse video series exploring North America’s remaining magnificent night skies and the threat of light pollution to our environment.

SKYGLOW explores the history and mythology of celestial observation, the proliferation of electrical outdoor lighting that spurred the rise of the phenomena known as “skyglow,” and the Dark Sky Movement that’s fighting to reclaim the night skies.

The project began as a Kickstarter campaign that ended as the fourth-most earning photo book on the site. Gavin and Harun also collaborated with the International Dark Sky Association (IDA) to explore the numerous towns and sites that the IDA has identified as official “Dark-Sky” Communities, Cities, Parks, Reserves and Sanctuaries.

To learn more about skyglow, light pollution and the dark sky movement there’s a TON of info on skyglowproject.com where you can also purchase the book and order prints.
