NGC6888, The Crescent Nebula on a crushed red velvet pillow of ionized hydrogen

NGC6888 is an emission nebula in the constellation of Cygnus and is located about 5000 light years away and about 25 light years across. It is formed by the solar winds of the Wolf-Rayet star, WR136, colliding with the gasses ejected by by the star when it became a red giant hundreds of thousand of years ago. It has produced two shock waves, one moving inward with its energy creating x-ray emissions and one moving outward creating an outer shell. This is a fairly dim object and almost invisible without the aid of Hydrogen Alpha and Oxygen III filters which make the object appear to pop out of the background as seen here.

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.
