SH2-132 - The Lion Nebula in HOO

This is one of those astronomy targets where I cannot quite make out the relationship between the name and the visual appearance of the object, but nevertheless this is SH2-132 or commonly known as The Lion Nebula.

 

I think the dark lines near the two dark areas may represent the lions mouth like an upside down Y, but who knows. This region is rich in HII, but also very rich in OIII as you can see by the blue in the image. I have produced both the HOO (Hydrogen Alpha+Oxygen III + Oxygen III as RGB) and the Hubble Palette SHO (Sulphur Dioxide II + Hydrogen Alpha + Oxygen III as RGB)
