The image was obtained using the wide-field view of the Mosaic camera on the Mayall 4 meters telescope at Kitt Peak National Observatory. The picture shows the nebula known as the "Ear Nebula". This nebula is relatively old. It was discovered in 2005 by the IPHAS of the Northern Galactic Plane. The picture is built with observations in the Hydrogen alpha (red) and Oxygen (blue) filters. The North is to the top of the image, while the East is to the left.
