Carina Nebula, NGC 3372

The Carina Nebula (NGC 3372; aka the Grand Nebula, Great Nebula in Carina, or Eta Carinae Nebula according to Wikipedia). Also, "four times as large as and even brighter than" the Orion Nebula, but less well known due to its exclusively southern hemisphere visibility. Discovered in 1752.

LRGB only (no Ha) using an HDR Luminance compiled from 3 sets of 18+ (each exposure group) luminance subframes 15s, 30s and 600s.

Foramen is the bright star or stellar system (a pair or more of stars said to be 5 million times brighter than the Sun) in the center, according to the plate solved annotation by Pixinsight.

The Keyhole Nebula is in the center as well. "The diameter of the Keyhole structure is approximately seven light-years," per Wikipedia.

This is my favorite pic yet with least likes on astrobin.

Description: slight crop, color tweak, NR, maybe time to step away from it for a bit!

I

Description: Cannot recall when/why I cropped the full image but looking back I like that better.

J

Description: Better version; HDR luminance, dynamic background gradient removal applied (division), no sharpening or deconvolution on the stars, because it's not really needed and hard to do without contributing noise to data that stands well on its own.

M

Description: combination of Ha and non-Ha LRGB

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.
