Eta Carina Nebula (Key-hole Nebula), NGC 3372
This is one of the most impressive objects in the sky of any type.  It is a southern object in the constellation of Carina that spans about 2 degrees. 
The red glowing gas clouds are split by huge dark lanes giving the appearance of a starfish.  The Eta Carina star which illuminates the nebula is
an unstable blue supergiant a million times more luminous than our sun.
