From Wikipedia: NGC 3324 is an open cluster in the constellation Carina, located northwest of the Carina Nebula (NGC 3372) at a distance of 9,100 ly (2,800 pc) from Earth. It is closely associated with the emission nebula IC 2599, also known as Gum 31. The two are often confused as a single object, and together have been nicknamed the "Gabriela Mistral Nebula" due to its resemblance to the Chilean poet. NGC 3324 was first catalogued by James Dunlop in 1826.

NGC 3293 (aka the Gem Cluster) is an open cluster in the Carina constellation. It was discovered by Nicolas-Louis de Lacaille in 1751. It consists of more than 100 stars brighter than 14th magnitude in a 10 arc minute field, the brightest of which are blue supergiants of apparent magnitude 6.5 and 6.7. There is also a 7th magnitude pulsating red supergiant, V361 Carinae.

NGC 3293 is associated with the open cluster NGC 3324. Both are fairly young, at around 12 million years old. They show some degree of mass segregation, with more massive stars concentrated near their centers.
