The coolest video of yesterday's annular solar eclipse

posted by Jason Kottke   May 21, 2012

Cory Poole made this video of the annular solar ecplise yesterday using 700 photographs from a telescope with "a very narrow bandpass allowing you to see the chromosphere and not the much brighter photosphere below it."

Cory says: "The filter only allows light that is created when hydrogen atoms go from the 2nd excited state to the 1st excited state." Very cool.
