Explanation: Only in the fleeting darkness of a total solar eclipse is the
light of the solar corona easily visible. Normally overwhelmed by the bright
solar disk, the expansive corona, the sun's outer atmosphere, is an
alluring sight. But the subtle details and extreme ranges in the corona's
brightness, although discernible to the eye, are notoriously difficult to
photograph. Pic |
