星图的方向和在地图的方向 按星图来找天空中的星星,当你把一张星图平放在桌子上时,不管你怎样转换图的方向,总不能和星空的实际方向一致。这是因为地球在我们的脚下,我们是从“上”向“下”看地球的。星空在我们的头顶上面,我们是从“下”向“上”看星空的,星图和地图标的方向恰恰相反。所以按星图认星星时,不应把星图平放在桌子上,而应该举在头顶上,这样星图所指的方向与星空的实际方向就一致了。
When you place a star chart on a table, no matter how you change the direction of the chart, you can not always agree with the actual direction of the sky. This is because the Earth is at our feet and we see the Earth from “up” to “down”. The sky above our heads, we are from the “down” to “up” to see the sky, stars and maps in the opposite direction. Therefore, when identifying the stars according to the star chart, the star chart should not be flat on the table, but should be lifted above the head so that the direction pointed by the star chart coincides with the actual direction of the starry sky.
