This is a crop of the Running Chicken Nebula. Its formal name is IC 2944 Lambda Centauri.  It is an area of gas and newborn stars that lies around 6500 light years away in the constellation of Centaurus.  The Running Chicken Nebula get its nickname from the birdlike shape of the brightest part of the nebula. 

This nebula is best known for its Bok Globules, dark dense dust clouds that are opaque to visible light.  Although, astronomers that have access to infrared telescopes can image within the Bok Globules and capture the stars forming within these areas.

This was a challenging image to process.  I wanted to portray a dramatic image that had a three dimensional quality.  The bright star, Lambda Centauri / HIP 56561 shinning away at Mag 3.1 dominated and outshone everything else in the image.  When I started to process, I began to wonder if I could do anything with the data.   That bright beacon had a massive halo.  But, I liked the way it floated above that ridge of gas.  Lambda Centauri almost seems to be recessed in a blue cloud.  Perhaps I have simply been staring at the image far far too long.
