Eta Carinae nebula

(NGC 3372) A large complex of dust and glowing gas in the southern Milky Way. The nebulosity is an extended H II region in which there are clusters of young stars. Dark lanes of cool dust divide the nebula into islands of glowing gas. One of these dark and irregular dust lanes is known as the Keyhole, which is used to identify the bright emission Keyhole nebula in which the object Eta Carinae is situated.

We spent time with a few other southern objects including Centaurus A (a galaxy known for its particular radio activity), the Jewel Box cluster (NGC 4755), and the Eta Carinae Nebula with its yellowish star within.
But here's the truth: if you were looking out of a starship's window in the midst of the Eta Carinae Nebula, it would look not like its dazzling Hubble panorama but about as it looks in a richest-field telescope under a rural sky.
Inside NGC 3372, known as the Eta Carinae Nebula, the bright 3.5 magnitude orange Eta Carinae is also surrounded by an orange-red nebula about 15" wide, called the Homunculus, named by Gaviola due to its resemblance to a small, stubby manikin.
Our 5-inch scope seemed to perform like an 8 under such dark and steady skies, enabling us to trace out structural detail in the extremities of must-see targets like 30 Doradus, the Tarantula Nebula, and NGC 3372, the Eta Carinae Nebula. The massive globular cluster Omega Centauri (NGC 5139) filled the eyepiece with millions of stars, drawing shouts from one happy guest that had us all in fits of laughter.
NGC 3372 (Eta Carinae Nebula) is the best example of a bright (diffuse) nebula in the entire sky.
The far-southern Milky Way contains some very famous and spectacular objects, including the Southern Cross, the Coalsack, the Jewel Box Cluster (NGC 4755), and the incomparable Eta Carinae Nebula (NGC 3372).
The Eta Carinae Nebula (NGC 3372) is a massive starbirth region in Carina that is easily visible to the naked eye under dark skies.
That's why the bright nebulae of the Sagittarius-Carina arm such as M16 and M17 stretch only to longitude 17[degrees] in this direction, whereas the Eta Carinae Nebula, also in the Sagittarius-Carina arm, lies 72[degrees] on the opposite side of the galactic center, at longitude 288[degrees].
From northeast to southwest these include M16 (the Star Queen or Eagle Nebula) in Serpens; the emission nebulae M17 (Swan), M20 (Trifid), and M8 (Lagoon) in Sagittarius; the open clusters M21 in Sagittarius and NGC 6231 in Scorpius; the open cluster and emission nebula NGC 6193 and 6188 in Ara; the open cluster NGC 4755 (Jewel Box) in Crux; and the giant emission nebula NGC 3372, also known as the Eta Carinae Nebula. All of the emission nebulae contain embedded clusters and/or associations of young stars, though in some cases these stars are heavily obscured by dust.
In 6800, the SCP slips within 1[degrees] of Upsilon and about 71/2[degrees] from the famous Eta Carinae Nebula.
"When I am gone, you will find me at any time in the Eta Carinae Nebula. That's where the Good Lord is cooking up stars faster than anywhere else, and I want a front-row seat." Priscilla died just days later, and after Bart passed away in 1983, we imagined the couple reunited at Eta Carinae.
MANY OBSERVERS rate the Eta Carinae Nebula as the greatest spectacle in the southern Milky Way.
