Dark Nebula LDN1161 in Hα-SII/OIII/OIII+rgb (Sh2-132 region)

Posted on September 8, 2020April 21, 2021

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.
