Constellation Carina
Carinae Nebula bright diffuse nebula surrounding n Carinae easily visible with the naked eye. Discovered by Lacaille 1751-52. This giant diffuse nebula is one of the largest H II regions (composed of ionized hydrogen gas) in our Milky Way galaxy. The star forming nebula NGC 3372 has produced the very conspicuous peculiar star Eta Carinae, which is among the most massive and luminous stars in our Milky Way, and perhaps in the universe.
Star forming region and its complex structure of bright area of gaseous emissions and dark absorption lanes bears examination with a wide range of apertures, it contains various star clusters and several double stars.

Note: This may not look much different to the short version but it is when you zoom in there is a lot less noise
