Focal Length:50mm
ISO:2000
Shutter:1/59 sec
Camera:Canon EOS 60D

For this shot I overexposed the inner corona on purpose to reveal more of the extent of the streamers in the Sun’s outer corona.

The pink at left is the chromosphere layer shining from behind the Moon just before the Moon uncovered the blindingly bright photosphere with a burst of light, the diamond ring.

It takes a lot of specialized processing, far beyond what I’ve done here, and stacking of multiple exposures to reveal the delicacy of structures that you can see with your aided eyes during a total eclipse. There is nothing more astonishing in the sky for its complexity and yet subtleness than the Sun’s corona. It is the main attraction at any total solar eclipse. You have not lived astronomically until you have seen the corona of the Sun with your own eyes.
