Outer reaches of Eta Carinae

This is just a tiny portion of the incredible Eta Carinae Nebula. It is a large complex area with bright and dark nebulosity, located in the Carina-Sagittarius Arm. This large diffuse nebula is four times larger than the Orion Nebula. The instrument used to create this image can just fit the full disk of the moon in the frame. The moon is about 30 arcmin across. If I could capture the entire nebula, it would span 120 X 120 arc min in size. It is a treat to look up and see this wonderful object from a dark location.
