Carina Nebula NGC 3372 / Keyhole Nebula

This is the Carina Nebula, NGC 3372. The picture was taken with an 85 mm refractor and even then, the whole thing didn’t fit in the field of view of that scope. It has many features that set it apart from most nebula in our galaxy. The nebula is very large, it extends around the central star 1 degree in all directions. To put that in perspective, it’s about twice the size of the Orion Nebula. In our galaxy, in addition to being one of the largest, it’s also among the most active star-forming regions known. At its center, just to the right of the central star is the Keyhole Nebula. That is on my list as a stand-alone target with a much larger scope and a camera that can capture its intricate detail. This wide field view doesn’t do the Keyhole justice. The central star is Eta Carinae. It is well-known and among the most massive stars in the galaxy. It’s in a group of stars referred to as luminous hypergiants. It is estimated to be 400 million times brighter than the Sun.

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.
