Planetary Nebula NGC 2438 shares the skies with the Calabash Nebula

Thursday, April 25, 2013: Planetary nebula NGC 2438 stands out brightly at top left, while at lower right the Calabash Nebula glows very faintly as a kind of upright light-bulb shape. 

The Calabash Nebula is also named the "Rotten Egg Nebula" owing to a relatively large amount of sulphur.
