NGC 6888, The Crescent Nebula (2023)

NGC 6888, also known as the Crescent Nebula, is a striking and intricate emission nebula situated in the constellation Cygnus, approximately 4,700 light-years away from Earth. The Crescent Nebula derives its name from its crescent-like appearance, which is primarily attributed to the presence of a massive, hot, and young Wolf-Rayet star at its core. This central star, known as WR 136, is a rare and luminous type of massive star that has already shed much of its outer layers through intense stellar winds and is currently in a late evolutionary stage. These powerful stellar winds, with velocities on the order of thousands of kilometers per second, interact with the surrounding interstellar medium, creating the visually stunning shell-like structure characteristic of NGC 6888.

While I imaged this target before, this version was my first attempt using the L-eXtreme filter on my ASI071MC OSC camera. This summer's conditions were much worse than normal with unstable air and presence of wildfire smoke, yet the RCAstro processes used were of great help cleaning up the data. Subframes taken on July 10, 11, 12 and 16, 2023.

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.
