Discovered by Royal Harvard Frost in 1906-8.
This bright nebula around the star Lambda Centauri is located within a few degrees of the more popular Eta Carinae Nebula.
The open cluster at the lower right is NGC 3766 (the Pearl Cluster). The strip of four bright stars in the centre of this object is open cluster IC 2944. The round nebula upper left is RCW 60 and the small nebula found centre top is RCW 61. This object is also known as the "Running Chicken Nebula."
