SH2-119

This is the first time I imaged SH2-119. It is also the first time that I processed an image only in SIRIL (no affinity photo etc) and just used BlurExterminator and NoiseXterminator to sharpen. I like the result. This image is a "natural color" composition so the resulting colors come close to the visible spectrum of the human eye.
SH2-119 (Sharpless 119 ) Sharpless 119 is a large complex of emission nebula in Cygnus, and is about 3 degrees east of the North American Nebula, located around the bright 5th-magnitude star 68 Cygni. I only shot 40 300 second images and am not sure if I want to shot longer.
Stewart Sharpless described sh2-119 as a Type 3, "bright" in his "Catalogue of H II Regions" published in 1959. The area is part of the Milky Way and is populated by numerous stars.The nebula emits all of its light in isolated emission lines. Mostly the lines of Hα, [OIII] and [SII], so I thought the Optolong L-Ultimate filter would be good to use.

[color=var(--lighterGrey)]In the middle of the image, just to the left of the brightest star, you will see a small planetary nebula PK 87-3.1, which can easily be seen in the larger image. [/color]

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.
