是晚,中国科学院云南天文台丽江观测站,前半夜薄云浮动,后半夜逐渐放晴。明亮的猎户座(参宿区域)在2.4米望远镜观测室背后缓缓落下,几乎同时天蝎座(商星附近)在300mm视宁度监测仪背后升起,当金星越过100mm日冕仪后,东方天空已开始发白。这就是2019年2月12日晚上的丽江观测站。

拍摄后记:2月中旬的丽江站远没有京郊及内蒙草原寒冷。地表附近气温在0℃上下徘徊。在户外通宵拍摄时,我准备的厚重衣物甚至没有完全披挂上阵。但是,后半夜大量袭来的潮湿气流,在海拔3200米的山顶,相对湿度达85%!这超出了我的经验。所以在视频里可以看到,商星升起的那两段,镜头逐渐起雾了。当然,也可以觉得这种渐变雾化效果有一种奇妙的视觉享受。但是,下次再外出拍摄,我一定会准备镜头除雾带……

音乐旁白内容:
We go about our daily lives understanding almost nothing of the world.
We give little thought of the machinery that generates the sunlight and makes life possible.
To the gravity that glues us to the earth that would otherwise send us spinning off into space.
Or to the atoms that which we are made..
and on who’s stability we fundamentally depend.
Few of us spend much time wondering why nature is the way it is.
Where the cosmos came from.
Whether it was always there.
If time will one day flow backward.
Or whether there are ultimate limits to what humans can know.
What is the smallest piece of matter.
Why we remember the past and not the future.
And why there is a universe?

小编点评:一段延时佳作。虽然参商不相见,但拍一晚上却可以把它们拍在同一段延时里。配乐很有意思,有点经历重大天文发现的感觉……
