This image shows you very indistinct diffused nebulae surrounding pi(in south) and delta(in north) Sco., forming the head of Scorpius, resistered as Sh2-1 and Sh2-7, respectively.
You can see that Sh2-1 has a mixed structure with reddish emission nebula and bluish reflection nebula.
And Sh2-7 in north looks vast round shape, including some clusters inside.
