M17 - The Omega Nebula

Messier 17, also known as the Omega Nebula or Swan Nebula, is one of the largest star-forming regions in the Milky Way galaxy. Located 5500 light years away from Earth, it is not far from the Eagle Nebula (M16) in the core of the Milky Way. At magnitude 6.0, it can be seen with the naked eye in dark skies, but is much better through binoculars or a telescope. M17 contains an open cluster of 35 hot, young stars which are responsible for the nebula’s glow. The cluster is only 1 million years old, which makes it one of the youngest known clusters in our galaxy.

I used some new image processing techniques on this one, including a new star reduction process in Photoshop. Previously, star reduction worked ok for me but also was affecting the look of my deep sky objects. I’m much happier with this new result as it only affects the stars and leaves the DSO alone, allowing me to have more freedom to adjust it on its own. It’s nice to go back and edit data from over the summer knowing that the winter objects are on their way!

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.
