NGC 6888, also known as the Crescent Nebula, glows brilliantly in this wide-field image captured in RGB and hydrogen-alpha (Ha). The hydrogen emission dominates the surrounding region, revealing the intricate filaments and shock fronts generated by the powerful stellar winds of its central Wolf-Rayet star, WR 136. Surrounding the nebula is a faint OIII bubble envelope, adding an additional layer of depth and structure.

In this image, you can also spot the “Soap Bubble Nebula” (PN G75.5+1.7), a small, nearly perfect spherical shell discovered only a few years ago. It appears like a tiny soap bubble suspended in space, making it a unique feature within the same field of view.

The Cave Nebula (Sh2- 155 or Caldwell 9) is an emission nebula of the Cepheus constellation.
It is a weak light nebula and very diffuse in a greater complex of nebula containing dark emission, reflection and nebulosity. It is located in the constellation of Cepheus and is about 2400 light years from Earth.
