APOD 20090818 荒地上的银河

来源:成大APOD

为什么选择荒地(Badlands)拍下这张星光灿烂的影像呢?事实上这是利用四张影像所拼出的全景图,在六月底的午夜里,向西南方星空长时间曝光,搭配着短暂的闪光对补光,而拍下这张精彩的影像。其中,影像的前景为美国 南达科塔州(South Dakota)的恶土国家公园(Badlands National Park)的Badlands Wall的特殊孤峰,这些山岳型态的孤峰是由松软的石块组成,由于相当容易受到风与水的侵蚀而展现出崎岖的外型。在南达科塔州的垩土国家公园里,古老的地层中富含了化石,其中一部分的化石可追朔至两千五百万年前,这些数据提供了马与剑齿虎演化的线索。在恶地地形左上方的是明亮的木星,右方则是即将西落的银河。

美得无法用语言来形容!

水星人 发表于 2009-8-18 21:25

如果语言无法形容,那还是看图吧!

很漂亮啊 不过我觉得补光有点过了 我喜欢用白光手电筒补光 容易控制补光的量 还可以对景物有选择性的补光

拼接?怎么拼?那样的话天空会不会错位?

太漂亮了 星星没有拖影就拍到这么多 天一定不错::070821_09.jpg::

这样的长时间曝光为什么不会拖出星迹来?

这个地方一看就不是住人的地方,又没有灯光!

c_luke 发表于 2009-8-20 01:00

照片确实很漂亮!不过拼图的问题是地景光线投影方向不一致,有错愕的感觉。

星空艺术,总有一天我拍的比他好!

c_luke 发表于 2009-8-20 01:03

我也发一个献丑了!初次作品,普通的数码相机。

相机放在赤道仪上跟踪的吧

如果用了赤道仪,地面和山头的场景不是就模糊了么?
