SH2-124

Sh2-124 is a large nebulous system, linked to the infrared source RAFGL 2789, which is identified with V645 Cygni, probably an O-class star or Herbig's star Ae/Be. The complex is probably located within the Orion Arm at a distance of about 8,480 light-years.

The main stars responsible for the ionization of the gases of the nebula would be a blue star of spectral class O7V and a blue star of class B2V, to which perhaps others could be added. The nebula hosts star formation processes and is, in fact, listed in the Avedisova Catalog as object number 1220; Some infrared sources have been identified in the interior, five of which have been identified by the IRAS satellite. Two masers were also detected, one with H2O emissions focused on the V645 Cygni component and one with methanol emissions.

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.
