Astrophotographer Rey Hernandez Made an Astonishing 54 Hour Photo

"I can't tell what [is] my limit, there [are] just so many targets and each yields [a] different outcome the more time you put into it.", says Rey Hernandez, who currently has reached 54 hours of exposure time on a night sky photo. He hopes to hit a 100 hours exposure someday to photograph more amazing constellations in our night sky
