2017 日全蝕

還記的2017年的那次日全蝕嗎？俺拍了幾張。焦距對的不太好，但畫麵還是挺有意思的：

下麵這張，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).
