M17 - The Omega Nebula

The Omega Nebula is between 5,000 and 6,000 ly from us and it spans some 15 light-years in diameter. It is considered one of the brightest and most massive star-forming regions of our galaxy. Its local geometry is similar to the Orion Nebula except that it is viewed edge-on rather than face-on. The open star cluster NGC 6618 lies embedded in the nebulosity and causes the gasses of the nebula to shine. It is one of the youngest clusters known, with an age of just 1 million years. All according to Wikipedia.The Omega Nebula is too far south for my Swedish horizon, but fortunately the Ikarus Observatory has kindly publicly posted data from Spain (https://ikiobservatory.com/data/M17_2020-10-30/) that I now took the opportunity to process. I made a HSO image (so Ha in the red channel and Sii in the green and Oiii in the blue). Used all the new XT tools in PI or PS.

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.
