It's an area of emission nebula within the Soul
Nebula. I have done the Heart and Soul nebula as a
mosaic. This is a closer look with a bigger
This area, like most emission nebulas, is a
star-forming region. The clouds you see are carved
out by energy from the stars within it. I have been
shooting a lot of emission nebula like this. Mostly
because I enjoy the interesting structures, but also
I can use narrowband filters which block light
pollution and allow me to capture data without
dragging everything hours away to find dark skies.
