It can take an exposure of several seconds to show all the detail in a moon corona.
The second ring was clearly visible to the eye and this image clearly shows parts of a third ring.
Castor and Pollux are the two stars above the moon.

In this sequence the corona image on the left received 10 times the exposure of the corona image on the right, and 1000 times the moon image.
I could easily see both of the corona rings and detail on the moon, which shows just how well the eye can cope with such a large range of brightness.
