This image was obtained with the wide-field view of the Mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory. M27, also known as the 'Dumbbell Nebula', is a famous planetary nebula. The central portion of the nebula is quite bright, however it also has a faint outer halo that is clearly visible in this deep image. The image was generated with observations in the Oxygen [OIII] (blue), Hydrogen-Alpha (red) and Sulphur [SII] (green) filters. In this image, North is left, East is down.
