The glorious Soul Nebula (Westerhout 5) in narrowband.
This is an emission nebula located in the constellation Cassiopeia and is a distance of 7500 light years from Earth. The Soul Nebula is sometimes also known as the Embryo Nebula or IC 1848, which is a designation used for the open star cluster embedded within the nebula. It is a vast star-forming region illuminated by the light of the young stars surrounded by star-forming clouds of dust and gas. The stars in the region are less than a few million years old and are only beginning their life.
