This is a very large and very faint nebula around the star Delta Scorpii which is in the center of the image. There is some very faint reflection nebula around the star, but the surrounding area is mainly red and does well with the Hydrogen Alpha filter. Only about half of the nebula is seen here and it lies next to a large reflection nebula, SH-1, so you need a very large FOV to capture the entire object. Image acquired by Steve Crouch near Canberra, Australia, which I processed.

Sh 2-7 is the core of a huge diffuse nebula and is ionised by the B0.2IVe subgiant binary Delta Scorpii, a member of the nearby Sco OB2 association.
