Description

The Wizard Nebula, Sh2-142, is an elongated HII/OIII emission nebula in the constellation of Cepheus, about 7,200 light-years (ly) from Earth, and approximately 110 ly across.   NGC 7380, an associated open cluster of young stars (5 million years old), was discovered in 1787 by Caroline Herschel.   At the center of the star cluster is DH Cephei (DH Cep), a rotating variable double star, that is believed to be the force driving the expansion of the gas and dust in the nebula, as well as triggering new star formation.

The image is rendered in a Hubble-like palette, which I think brings out some of the features that are not seen in an Ha rendering.
