IC 1318; South of Sadr Giant star in the Cygnus constellation

The Sadr Region in the Cygnus refers to the hydrogen emission nebula surrounding Sadr (Gamma Cygni) in the cross of the constellation Cygnus. In this area of the night sky, you will also find even more deep-sky astrophotography targets such as the Butterfly Nebula (IC 1318), and the Crescent Nebula.Sadr (a supergiant) has 12 times the mass of our Sun and about 150 times our Sun’s radius. IC 1318 is considered to be the diffuse emission nebula surrounding Sadr.

Two panel mosaic: Each Panel: 10 x 180sec light subs + 30 darks and 30 Flats

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.
