A detailed, close view of the Elephant's Trunk.
IC1396A is the designation for the Elephant Trunk Nebula: a dense cloud of ionized gas that has been compressed into a round shape from opposing forces of a massive star and several younger stars. The larger star illuminates the edge of the cloud and provides contrast for the trunk that curls at the end of a long column of interstellar dust. It is believed this compressed gas is forming into protostars.
In the constellation Cepheus lies a large area of glowing cosmic dust that is silhouetted by surrounding clouds of dark dust. This region is believed to be a star-forming area using materials like the particles that make up a massive column that curls at the end like an elephant's trunk. This is a wide field view of IC1396, the Elephant's Trunk Nebula, processed from regular light and narrowband using the Optolong l-eXtreme filter.
