The Gabriela Mistral Nebula was named after a Chilean poet, diplomat, educator and humanist, who was the first Latin American author to receive a Nobel Prize in Literature. It is a difficult object to image because of the steeply fading gradient of nebulosity, some of it becoming exceedingly dim. It lies beyond the NNW edge of the huge Eta Carinae Nebula, part of which which can be glimpsed upper left.
The brightest star in the nebula is a yellow-white super-giant,V370 Carinae at magnitude +5.5, a pulsating variable star.
Lower right lies the Gem Cluster, a beautiful tight little cluster of fifty to a hundred young and mostly hot blue B type stars but with a prominent seventh magnitude star V361 Carinae, which has a lot going for it.
V361 is a red M-type super-giant, with a diameter listed as a whopping 356.8 times the diameter of the Sun. It is also a pulsating variable star and part of a double star system. It has apparently evolved faster than the other stars.
