NGC 3918 is a bright planetary nebula in the constellation Centaurus, that is called the "Blue Planetary" or "The Southerner". It is the brightest of the far southern planetary nebula NGC 3918 was discovered by Sir John Herschel in March 1834, and in easily visible in a small telescope. The round or even slightly oval diameter is telescopically between 8 to 10 arcsec, though deep images extends this to about 19 or 20 arcsec.
