M17 WIDEFIELD

M17 is a bright emission nebula located in the constellation Sagittarius.
About 6,000 light-years from Earth, it's one of the brightest and easiest to locate summer emitting regions. In fact, under dark skies, it's clearly visible to the naked eye and interesting observations can be made through binoculars or small telescopes; with large apertures the observation of this nebula from the eyepiece is stunning.
M17 is an H II region in which star formation is active, made bright by the light radiation of the spectral class B stars formed in it.
M17 and M16 are angularly (distance of 2.5° in the sky) and physically close, in fact they are located a few light years away from each other and are connected by a nebulous complex of which they are part.
This image is a widefield around M17, in which we can see a distribution of =HwtZe=jCAhz ChMk0b=ryNqvbionized gas dusts present in the region.

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.
