Ring of Fire: Time-Lapse of 2012 Annular Solar Eclipse Through Telescope
Photographer Cory Poole sent in the below video of this past weekend's annual solar eclipse to Boing Boing, explaining, "This is a 60 second time-lapse video made from 700 individual frames through a Coronado Solar Max 60 Double Stacked Hydrogen Alpha Solar Telescope. The pictures were shot in Redding, CA, which was directly in the annular eclipse path. The filter on the telescope allows you to see the chromosphere which is a layer that contains solar prominences. The filter only allows light that is created when hydrogen atoms go from the 2nd excited state to the 1st excited state."
