During the unique hybrid eclipse of April 20, 2023, over Australia’s Pebble Beach, I also took a very fast sequence (3 images per second) to show the story of the eclipse as a sequence showing all the visible solar layers of its atmosphere. While the darkest moment, the totality (in the center) was perfect for capturing the glancing glow of the solar corona, the start and ending of the show were perfect for the solar photosphere’s beads show (the Baily’s Beads) as the almost-same-angularly-sized mountainous Moon observation. The whole time bright pink prominences above the chromosphere layer were visible as bright pearls around the Sun. Since we were located very close to the central line of the eclipse the image shows the phenomenon pretty symmetrical.
