还记的2017年的那次日全蚀吗？俺拍了几张。焦距对的不太好，但画面还是挺有意思的：
下面这张，angle of each individual image in this picture is accurate - as the camera recorded it (I mean, relatively accurate, depending on how truly horizontal the camera was set. Each taken with 300mm lens + 1.4 Magnifier).
Therefore the picture shows the kind of path - left down first - that the moon traveled across the sun, as seen from where we were observing (USA).
At the same time, the sun was moving through the sky in a NEE to SWW direction - due to rotation of the earth. It appeared to have moved approximately 2/3 of its size in diameter during the totality (around 3 minutes).
