Greetings from the Euranian star cluster.
While no images are known to exist of the Great Nebula of Eurania, the wide variety of available images of other famous planetary nebulae offers suggestions of what it might resemble. Here is a small selection of Great Nebulae, for your viewing pleasure.
The Cat’s Eye Nebula (NGC 6543, Caldwell 6), one of the first planetary nebulae discovered, also has one of the most complex forms known to this kind of nebula. Eleven rings, or shells, of gas make up the Cat’s Eye.

The Helix Nebula (NGC 7293) is a popular target of amateur astronomers and can be seen with binoculars as a ghostly, greenish cloud in the constellation Aquarius.

The Eskimo Nebula (NGC 2392). This planetary nebula began forming 10,000 years ago, when the dying star at its center began flinging out bubbles of gas and matter.

The Rosette Nebula (Caldwell 49) is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy.

One can only imagine what a journey along the perimeters of these spectacular regions might offer.
