Cometary Globule 4 - The Galactic Shai-Hulud

CG4 strikingly resembles the sandworm in the Dune SF novels. The Ha channel brings up interesting details in the nebula. I processed the HaLRGB picture through two different workflows involving either PI or AF. There were some noticeable differences between the resulting pictures. However, I liked very much both of them and could not decide which one to select for this post. I eventually decided to blend the PI and AF pictures together!
