Amazing Video of Solar Eclipse Shows Sun’s Structure

This time-lapse video of Sunday’s solar eclipse highlights the Sun’s outer layers

About the video: The photographer Cory Poole constructed the video by pasting together 700 photographs taken with a Coronado Solar Max 60 Double Stack telescope. According to Jason Kottke, Poole used a filter that only allows light from hydrogen atoms moving from the 2nd excited state to the 1st excited state. This allows Poole to highlight the chromosphere, the Sun’s lower atmosphere.
