The Crescent Nebula NGC 6888/Sharpless 105

An emission nebula in Cygnus, 5000 lights years from my orchard. This cosmic shell shape was formed formed by the interaction of fast and slow moving stellar winds produced as the central Wolf-Rayet star (WR 136, HD192163 ) became a red giant about a quarter of million years ago. https://en.wikipedia.org/wiki/WR_136

20 minutes with a 92% moon, good transparency but horrible seeing FWHM was all over the place, so pretty pleased with the result- was able to pick up a good deal of the OIII emissions as well as the main HII regions-

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.
