M17 Swan Nebula

This 21h HaRGB image of the star-forming region of M17 was captured at DeepSkyWest in Rio Hurtado, Chile in June-July 2021. The pink-to-red color comes from hydrogen gas clouds that are being excited by extremely hot newborn stars. The M17 region is the brightest portion of a giant 40 light-year wide molecular cloud (GMC) that is the largest in the Milky Way. It is located approximately 6,000 light-years away in the Sagittarius spiral arm which makes the isolated optically visible "Swan" portion of M17 roughly 15 light-years across.

Version D is a rotated and cropped version of the original (previous versions):
It has North to the left and East toward the top and now I think I can finally see the Swan in M17 floating on the water, which had escaped me in the uncropped versions that had North up. You may have to stare at it a bit to see the head, eyes and beak on the graceful white neck of the swan as it floats toward us on the surface of the water with its raised wings behind it . I am struck by its great beauty.

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.
