SH2-129 & Ou4 Flying Bat & Squid Nebula

Sharpless 129 is an H-alpha emission nebula commonly called the Flying Bat Nebula located in Cepheus very close to the famous IC 1396 (the nebula that contains the Elephant's Trunk). The large blue/green nebula inside it, which is over a degree long, is formally known as Ou4 but is colloquially called the Squid (or Giant Squid) Nebula. Ou4 is remarkable for having been discovered very recently, in 2011, by amateur astronomer Nicolas Outters (hence the "Ou" in "Ou4"). It was originally called a planetary nebula but is now thought to be some kind of bipolar outflow from the bright blue star at its center (which is HR 8119).

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.
