This is an object known as IC 1871. 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 telescope.
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.
