A "deep sky object" is any object outside our solar system 'except' a star; the name is a "collective term" used to refer to such things as galaxies, star clusters, nebulae, and so on.

“深空天体”泛指太阳系以外除了恒星的任何天体，它是一个包括星系、星团、星云等等天体在内的集合名词。

Many of the brightest deep sky objects also have "popular names" by which they're often referred to, such as "Andromeda Galaxy", "North America Nebula", "Blinking Planetary", and so on.

那些最亮的深空天体还有常用“俗名”，比如“仙女座大星系”、“北美洲星云”、“闪耀星云”等等。

Most deep sky objects don't have a "popular name" - if we want to find them, we need to know their catalog number, or at least one of their catalog Numbers, since most objects have several.

大部分深空天体没有“常用名称”，要找到它们，必须知道至少一个星表编号——大部分都有好几个。
