Near the end of the total solar eclipse of August 21, 2017, light from the solar photosphere streams through lunar valleys, showing a bright spots signaling the end of totality. This image was made in eastern Wyoming in pristine clear blue skies. What an amazing sight! Note (if your monitor is has a good color calibration) that Bailey's beads appear white and the solar corona surrounding the Moon is a gray-green in this natural color image. The pink color of the prominences is due to emission from hydrogen (red hydrogen-alpha + blue hydrogen-beta and hydrogen-gamma). These colors are similar to many hydrogen emission nebulae in the night sky.
Technical. Canon 6D 20-megapixel digital camera, with a 1.4x teleconverter and a Canon 500 mm f/4 telephoto lens on a fixed tripod. Exposure: 1/256 second at f/11, ISO 200.
