On Aug 21, 2017, the total solar eclipse occurred in USA crossing from west to east coasts. Our group composed of ten members tried to observe the rare event at Salem, the capital city of Oregon where faces the Pacific coast and is comparatively easy to access from Japan. The day was blessed with the fine weather; we could observe and enjoy the perfectly all progress including the partial eclipse for about two hours and a half under the best conditions.
An upper image shows you the corona's extent captured at the almost maximum eclipse. The image has been displayed by turning the celestial north direction upward and cropped with an equivalent focal length of 700mm. The image covers a field angle of 2.93×1.96°. In that day the sun positioned in the western Leo, you can detect the Regulus in left edge of the image.
I have provided other images and movies of this solar eclipse on and after the next page.
