The Great Carina Nebula (NGC 3372), H & O emissions

The Great Carina Nebula, (NGC 3372, Eta Carina Nebula) lies in the Carina-Sagittarius Arm of our
Milky Way Galaxy about 8,500ly away. It is one of the highlights of our southern skies, and comprises a
complex arrangement of bright and dark nebulosity. Also embedded within it are a number of open
clusters of bright, hot, young stars which include O-class and Wolf-Rayet stars (e.g. Trumpler 14,
Trumpler 16, WR 25). Various features of the main nebula have been identified and given common
names (e.g. the Homunculus Nebula, the Defaint Finger, the Keyhole Nebula, the Mystic Mountain).

Nicholas-Louis de Lacaille discovered this nebula in 1752. The eponymous star near its centre is the
hypergiant, η Carinae, with a mass 100-150x and a brightness 4,000,000x our Sun. It is amongst the
most luminous stars in our known galaxy.

I have used a H+O triband filter in an effort to display the nebulosity of this complex region in
greater detail.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
