[color=slategray]The Sombrero Galaxy is one of many showpieces of the Virgo Cluster of galaxies. Even at a distance of 40 million light years its beauty and mystery are not diminished. The Sombrero illustrates how incredibly thin the disks of spiral galaxies are. In this case the galaxy is inclined from our perspective by a mere 6 degrees. The extended halo which surrounds the galaxy is where orbiting globular star clusters are found (just like in the Milky Way). Other examples of edge-on spiral galaxies include [/color][url=http://www.noao.edu/outreach/aop/observers/n891.html][color=slategray]NGC 891[/color][/url][color=slategray] and [/color][url=http://www.noao.edu/outreach/aop/observers/n4565.html][color=slategray]NGC 4565[/color][/url][color=slategray].[/color]

很好很弓虽大~bbbb39

很漂亮，赞一个

我C....都TM的什么人拍的啊

差距太大了~~什么时候C11也发挥一下威力，拍出十分之一的效果我就满足了

嘿嘿。等派兄的7“APO来了，绝对有的一比

到时就看派兄得了，试试拍M104，PK他的20寸RCbbbb39

楼上的你的这毒放的，也算把坛子里的APO毒给杀杀了

摄影终极选择应该还是RC，毕竟口径在那摆着，各种条件等等都是为摄影而生的

是草帽吗？？？？？？？

回复 10# 的帖子

M104（草帽星系）

好专业！教科书式的照片！

赫赫，看着就是。好多人特喜欢这个星系！

呵呵..我是目视派

这个星系不好拍啊，需要口径支持:lol

快赶上哈勃了...........2Tw

刚刚看了个哈勃照片十佳,第一个就是草帽星系,和这个样子差不多......
