The bright inner corona during totality on August 21, 2017 was captured with a Canon 40D and Canon 100-400 zoom lens at 400 mm, f/8, 1/250 sec, ISO 100.

The reddish regions are solar prominences, part of the sun’s chromosphere layer, and easily captured — when present — with a hydrogen alpha scope. The coronasphere, on the other hand, while ALWAYS present, — is not visible except during a total solar eclipse.
