Time-Lapse Photography Captures Galactic Core of the Milky Way

May 20, 2009


This gorgeous video is a compilation of shots taken with a Canon EOS-5D every 20 seconds over about nine hours at a star party in Fort Davis, Texas. It’s a humbling sight.

Some specifics: The Canon was equipped with a fisheye lens (an EF 15mm f/2.8 lens) and powered with an external battery to capture all that goodness. The more interesting part is the replacement anti-alias filter the photographer, William Castleman, used: The Canon’s stock AA filter blocks out certain red wavelengths to achieve a “more desirable” skin tone, but if it’s replaced with a filter that lets those wavelengths in, you’ve got yourself a camera capable of shooting a galaxy, as seen here, even if we can’t see it with the naked eye. Really, really cool stuff.
