The Solar Eclipse at third contact: the corona, chromosphere. prominences, earthshine, and then the diamond ring. The star Regulus is at the upper left. I incorporated the deep blue sky that is an important part of my visual memory with Regulus and the corona from just before 3rd contact. The chromosphere, prominences, and fist glimpse of the diamond ring are from the moment of third contact. Taken from Deidre's 360 view near Torrington, Wyoming on 2017-08-21 17:48 UT. Forty-six images HDR composited from 3 stacks for the corona, earthshine, and diamond ring. Images exposed for from 1/1000 sec to 5 sec at ISO 100 at f 11.2 using a Vivitar 200 mm prime telephoto lens with 2X teleconverter and Sony a6300 camera on a Vixen Polarie mount. Questar 1350/89mm telescope, f15, (for earthshine) with a Sony NECX-5N camera at prime focus. This image was a Flickr Explore Selection (500 most interesting images of the day out of roughly 2,000,000) for Sept 12, 2017.
