Crescent Nebula (left) + Soap Bubble Nebula Right from the center)

Crescent Nebula (left) + Soap Bubble Nebula (Right from the center) - The Crescent Nebula (also known as NGC 6888) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth - It is formed by the fast stellar wind from a Wolf-Rayet star colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures - The Recently discovered Soap Bubble Nebula is likely a planetary nebula, the final shroud of a lower mass, long-lived, sun-like star destined to become a slowly cooling white dwarf. While both are some 5,000 light-years distant, the larger Crescent Nebula is around 25 light-years across. - Photo taken with a CFF-185 APO & ZWO camera ASI-6200 MC Pro - OPT Triad Ultra Quad-Band Narrowband Filter: 191 x 300 sec = 16 hours - Star colors: 100x300 sec. = 8.3 hours, total: ~ 25 hours. Location: “Eye in the Sky” telescope hosting, Raspay, Spain. (c) July 2021, Andre van Zegveld

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.
