Sh2-119 in Cygnus

Sh2-119, also known as Clamshell Nebula, is a large and diffuse nebula in the constellation Cygnus. It was fairly unnoticed but recently it is becoming more popular in the astrophotography community, with several top notch photos being published lately.
It features a large Ha region but also a fairly bright Oiii one around 68-Cygni, a hot blue giant star transitioning to supergiant. This type O star is surrounded by a ring shape nebula, likely a Strömgren sphere (a structure also seen in the Rosette nebula). The highly energetic UV radiation emitted by 68-Cygni lis the Ha clouds around, rendering this 3-D look of Sh2-119.This area also has other structures like Bok globules, LDN dark nebulas and right on the left of 68-Cyg, a small planetary nebula PK 87-3.1.

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.
