Totality

Totality
Totality Totality during the total solar eclipse of August 21, 2017 as seen from Madras, Oregon. Note the wispy nature of the corona, the outer atmosphere of the sun which is visible only during a total eclipse. Also note the reddish solar prominences (particularly around the 1 o’clock position on the solar disk) caused by bright material being thrown up far above the photosphere (“surface”) of the Sun. Four different exposures from a DSLR camera with a 250mm lens were combined to bring out broader detail in the corona (whose brightness drops off rapidly with distance from the Sun). Bruce Betts
