Brief Description   This image has composed three shots of maximum eclipse and diamond rings at the second and third contacts of total solar eclipse on Aug 21, 2017 observed at Oregon, USA. Although the totality has only 1min 52sec, the day was blessed with fine weather and I could appreciate under best conditions.
