NGC6888 Crescent Nebula and the Soap Bubble

There's a lot going on in this image of an area about 1.5 degrees wide in the constellation Cygnus (not far from the central star representing the Swan's body). The most obvious feature is the Crescent Nebula (NGC 6888), the bright emission nebula above and right of center. This nebula is the result of a stellar wind from WR136, the bright Wolf-Rayet star near the center. Left of center is the Soap Bubble (PN G75.5+1.7), a dim blue planetary nebula. Planetary nebulae are formed when stars like our Sun late in their lives begin to shed their outer layers. In the lower left corner is a small open cluster, IC 4996. At the top just left of center is a very nice double star pairing the distinctly reddish carbon star RS Cygni with a blue-white neighbor. The entire region is awash in streams of interstellar gas with active star formation.

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.
