上面9张图的拍摄时间:
20:15; 20:34; 20:51; 20:59; 21:05; 21:11; 21:17; 21:27; 21:39
我出去拍一张, 回屋里来喝点热水, 做点家务什么的, 时间有点random. 到9:30pm之后的全食时间段就很难拍了, 因为为月亮露脸的太少了, 光信号少, 也不容易瞄准, 当然要有长炮筒就容易些了, 可惜我没有。
Why is the moon red on full eclipse ?
""The Moon does not completely disappear as it passes through the umbra because of the refraction of sunlight by the Earth’s atmosphere into the shadow cone; if the Earth had no atmosphere, the Moon would be completely dark during an eclipse. The red coloring arises because sunlight reaching the Moon must pass through a long and dense layer of the Earth’s atmosphere, where it is scattered. Shorter wavelengths are more likely to be scattered by the air molecules and the small particles, and so by the time the light has passed through the atmosphere, the longer wavelengths dominate. This resulting light we perceive as red. This is the same effect that causes sunsets and sunrisesto turn the sky a reddish color; an alternative way of considering the problem is to realize that, as viewed from the Moon, the Sun would appear to be setting (or rising) behind the Earth."
