Cory Poole—science teacher at University Preparatory School in Redding, California, and Gizmodo reader—has composed this 60-second time lapse video made from 700 frames captured by a Coronado Solar Max 60 Double Stacked Hydrogen Alpha Solar Telescope. His words:
The pictures were shot in Redding California 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.
