Description

The crescent nebula is a Wolf-Rayet nebula, formed by the strong stellar wind originated by Wolf-Rayet's star HD 192163.

But in this image we can also see in the lower left a small bubble-shaped nebula, known as the Soap Nebula.

For this image I have used data obtained with the narrow band filters Ha and OIII and RGB for the stars, combining them using the HOO palette.
