M42+herschel H33-4

拍摄的时候, 对M42 的具体位置不是很了解,天真地想把M42 尽量靠左边,留下右边拍摄暗云气, 那里知道,由于天空不干净,出来大片污染光, 前N次练习处理都裁剪了.这次处理后,仔细看过,再问同好, 再对照SKY6 , 却发现无意中吧H33-4 拍了进来, 于是也不管污染光的问题了. 一并贴出来分享一下.(今日,在论坛大侠STEVE指点下, 学会 PIXINSIGHT 的DBE功能,把如下图片重新处理后,光害除去不少, 方能招摇见人.)

NGC 1999 is a dust filled bright nebula with a vast hole of empty space represented by a black patch of sky, as can be seen in the photograph. It is a reflection nebula, and shines from the light of the variable star V380 Orionis.

It was previously believed that the black patch was a dense cloud of dust and gas which blocked light that would normally pass through, called a dark nebula. Analysis of this patch by the infrared telescope Herschel (October 9, 2009), which has the capability of penetrating such dense cloud material, resulted in continued black space. This led to the belief that either the cloud material was immensely dense or that an unexplained phenomenon had been detected.

翻译如下:

NGC1999是一个充满了明亮的星云尘埃带着带有一个透出黑色空间的巨大空洞,正如图片所示。这是一个反射星云,闪耀着从变星V380 Orionis发射来的光.　　
　　它是先前认为的黑色空洞部分是一个密集的尘云和气体,它通常会阻挡可以正常通过的光,这被称为暗星云。红外望远镜赫歇尔对这样密度的星云物质具有穿透力, 它对这个黑色空洞的分析(2009年10月9日表明这是个连续的黑色空间.这结果指出了这团星云物质具有巨大的密度,同时探测到了一个尚无法解释的现象.

哈勃望远镜/ WFPC2在2000年捕捉到到的

关于H33-4的发现,曾经有过一番探讨.

火星老胸，你还是要去烧烧 环境，技术也需要多提高，你这张M42 我说实话，真的是拿不出手
而且我早就建议你 ...

感谢指教.慢慢烧不在乎精品,先烧过程
