Sharpless 119, also known as the Clamshell Nebula, is a large complex of emission nebulosity in Cygnus, about 2 degrees east of the much more famous North America Nebula.
It is located just around 68 Cygni, a quite bright star of magnitude 5 and one of the stars responsible for ionizing the surrounding gas.
Sharpless actually describes it as Type 3, "bright" in his famous "Catalogue of H II Regions" published in 1959. Interestingly, there are several dark lanes and dark globules overlaying the nebula. The area is part of the Milky Way and is populated by numerous stars.

This image is acquired with the Takahashi FSQ-106ED refractor and FLI PL16803 camera from Telescope Live in IC Astronomy Observatory, Oria, Spain.

Total integration time 360 minutes
SHO: 12 sub-frames of 600s with each filter.
Dataset Telescope Live.

Processing with PixInsight (using Autointegrate.js script from Jarmo Ruuth), StarXTerminator, Photoshop CC with AstroPanel Pro, Astronomy Tools, Topaz Sharpen AI and NoiseXTerminator plug-ins.

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.
