The Eta Carinae Nebula, NGC 3372; is a large, complex area of bright and dark nebulosity in the Southern Hemisphere constellation Carina. The nebula is approximately 8,500 light-years (2,600 pc) from Earth. Although it is four times as large as and even brighter than the famous Orion Nebula, the Eta Carina Nebula is much less well known due to its location in the southern sky. It was discovered by Nicolas-Louis de Lacaille in 1752 from the Cape of Good Hope. The image is 60 minutes of exposure time through a 20 inch Planewave TDK reflector at the Siding Spring Observatory at NSW Australia, courtesy of Dr. Christian Sasse of iTelescope.net.
