This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. Sh2-68 is an ancient planetary nebula that is estimated to be at least 45,000 years old. The diffuse orange emission to the upper right is the result of the planetary nebula's motion through the disk of our galaxy. The bluish interior is from energized oxygen atoms. The progenitor star is the very blue star at the center of the bluish gas. The image was generated with observations in the Hydrogen alpha (red) and Oxygen [OIII] (blue) filters. In this image, North is right, East is up.
