This image is dominated by the emission nebula known as LBN 331. The bright star central in the image is 32 Cygni. 32 Cygni is a binary star system (32 Cygni A and B). The

orbital plane of the two stars is nearly aligned with the line of sight to Earth. This alignment from Earth's viewpoint becomes an eclipsing variable star system known as

V1488 Cyg (1147 day cycle). This emission nebula lies (visually) in a dense star region of the Milky Way. This field is also well represented in the DWB catalog - the brighter

filaments of LBN 331 also have the DWB designations of DWB 179, 178, 177. (Credits: Jim Thommes)

Omicron-2 Cygni is an orange supergiant star in the constellation Cygnus. At 1,040 light years away, it is the 498th brightest star in the Earth's sky, where it shines at an

apparent visual magnitude of 3.96. Omicron-2 Cygni is the primary component of a multiple-star system. The iron abundance of Omicron-2 Cygni is -0.33 (46.8% of the Sun). It is

moving through the Galaxy at a speed of 10.2 km/s relative to the Sun. Its projected Galactic orbit carries it between 24,000 and 28,000 light years from the center of the

Galaxy.

Common designations: Omicron-2 Cygni, 32 Cygni, HIP 99848, HD 192909, HR 7751

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.
