This dark nebula belongs to the head of the Lion Nebula or Sh2-132.
Amazing fight on this complex area where a large number of dark nebulas, emission gases and eruptive stars give to us this nice show.
I need to explore more in detail this region on my next captures!!!
On this picture I integrate more than 75 hours in narrow band and rgb data to resolve all possible details and structures.
Processed on natural colors using a palette ha+Sii / Oiii / Oiii and RGB stars.
