Want to learn how to take stunning time-lapse videos of the night sky? Then join S&T's live webinar on Monday, June 19, 2017, to learn the secrets of how to take awe-inspiring time-lapse videos of the Earth and sky at night with world-renown photographer Babak Tafreshi.

On Monday, June 19, I'll be hosting Sky & Telescope's next online webinar, "The Sky in Motion: Time-Lapse Astrophotography" with National Geographic and S&T Contributing Photographer Babak Tafreshi. Babak has traveled the world capturing breathtaking nightscapes from some of the most beautiful locations on Earth.

"When I started nightscape photography over two decades ago, making videos of the night sky was a real challenge with either analog cameras or noisy first-generation digital sensors," says Babak. "A view of the moving Milky Way over the night landscape was an impossible dream for cinematographers back then, but now it’s an easy target for amateurs. I started time-lapse imaging when I shifted from analog to digital in 2006. Today, night-time time-lapse photography is one of the most popular activities for both hobbyists and pros, thanks to improving low-light performance of digital cameras. As easy as it sounds, there are still many challenges to deal with to achieve proper time lapse."

That's Monday, June 19th, at 2:00 p.m. EDT (18:00 UTC). Price: $29.99

Babak Tafreshi

Sky & Telescope Contributing Photographer Babak Tafreshi, a National Geographic photographer and leader of The World at Night program (twanight.org), is a master at nightscape imaging that merges art, culture, and science. His images reconnect people across the globe with the beauty of the night sky and the value of preserving natural nights.

Among his other titles are science journalist, photo ambassador for the European Southern Observatory (ESO), and board member of Astronomers Without Borders (AWB). Born in Tehran, Babak is now based in the Boston area but travels the globe seeking compelling nightscapes to photograph. Over the past two decades he has spent about a thousand nights imaging under the stars on seven continents.
