“iGAO为生活加点料”内蒙古“85后”iGAO为生活加点料跟踪半月拍到阿特拉斯彗星

  中新iGAO为生活加点料网鄂尔多斯11月4日电 (李iGAO为生活加点料爱平 白士城 戈浩宇)紫金山—阿特拉斯彗星(以下简称阿特拉斯彗星)6万多年才到访地球一次,被称为“2024年最值得期待彗星”。

  内蒙古自治区杭锦旗摄影爱好者苏伟经过半月的跟踪拍摄,让外界看到了阿特拉斯彗星的面貌。

  38岁的苏伟是杭锦旗摄影家协会主席,摄影外,他也是一位天文迷。近期,当他从电视、网络上得知阿特拉斯彗星有可能出现在他的家乡上空后,便决定带领孩子一起跟踪拍摄。

  “今年鄂尔多斯的秋天以阴雨为主,连续阴天近半月,一直没有等到合适的拍摄天气。这期间拍了5至6次都未成功。”苏伟说,眼看就要错过最佳观测期,最终在3天前等来了晴天。

  夜空下,他在杭锦旗库布其沙漠腹地终于拍到了阿特拉斯彗星,还利用拍摄技术成功和阿特拉斯彗星合影iGAO为生活加点料

  苏伟回忆说,“当时夜幕低垂,四周一片漆黑,这里没有任何光污染,是拍摄阿特拉斯彗星的理想地。”

  苏伟拍摄阿特拉斯彗星用的是相机延时拍摄技术,需要等待3个小时左右。在等待过程中,苏伟还和自己的孩子通过天文望远镜观测阿特拉斯彗星,并给孩子讲解阿特拉斯彗星的相关知识。他觉得,这是一次现场的天文教学课。

  漫长的等待后,阿特拉斯彗星终于被拍摄到了。苏伟指着照片说:“从画面上看,阿特拉斯彗星运行的轨道是一个椭圆形,尾部带有黄色,如梦如幻。”

  紫金山—阿特拉斯彗星由中国科学院紫金山天文台首次发现,编号为C/2023A3,是国际小行星中心发布的一颗逆行轨道长周期彗星。苏伟认为,能拍到阿特拉斯彗星,对自己的一生意义重大。(完)
