Description

This beautiful flower-like PN in Canis Minor is 2300 LY away from us, and spans 6 arc-minutes, corresponding to a 4 LY diameter.
The image reveals some central Oiii in the nebula, but it is weak compared to the dominant Ha emission so I had to stretch the Oiii signal a bit more than Ha to make it appear. The progenitor star is most likely the small blue star in the center of the nebula. The nebula was hardly visible in the RGB data, which mainly contributed the star color.

This is my third image taken with the Margareta Westlund Telescope in southern Spain, owned by the Swedish Amateur Astronomical Society and available remotely to its members.
