NGC 6888, the Crescent Nebula in Cygnus

As a large suspcious cloud came about, I rushed to dismantle the setup -- women and children, eehh, electronic parts first. I must confess I am still quite agile in situations like this. A few seconds later a skol came down. About half of the 60 frames were orange because of thin clouds but stacked them anyway as it remained cloudy after that sky shower. Thanks to Starnet++ the nebulosities around the star Sadr as well as the Crescent nebula in the center had no other choice but to appear though with noise due to lack of integration. Actually, I was aiming at taking pictures of each nebula individually at a longer focal length. Shortage of cloud-free sky forced me to round them up with the Samyang 135mm at f2.8. Anyway, my first Crescent nebula... nah, there were better nights under the sky, yet no complaints, it is still quite enjoyable.

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.
