The Solar corona during the August 21, 2017 total solar eclipse. Itâ€™s not a single image but a stack of multiple photos shot with exposure times from 1/4000 to 4s. Itâ€™s absolutely impossible to capture the whole range of brightness of the solar corona in a single exposure. You can even see the Earthshine on the Moon.
The corona might look impressive in the photo but itâ€™s not even close to the real thing. I say it again: go and see a total solar eclipse with your own eyes.
