Sh2-119

Sh2-119 is a vast emission nebula visible in the Swan constellation. Very close to the famous North America nebula and often forgot about because of its proximity to it. In the southern part (on the left) of the nebula, thin filaments and cocoons of dark nebulae are visible, which contrast strongly with the nebula and the star field.

This nebula looks very interesting with its "misty" clouds of gas that appear to flow either in or our of the central OIII core. This was an interesting image to process. The OIII signal was nearly non-existent in individual subs. Only when stacked did the faint central mist of OIII become apparent. The Ha data had a nice variety of sharp features and a nice misty look to it. The dark voids were very prominent in the stacked file, they must be very opaque and thick to block out everything behind them.

After countless revision uploads in this target I settled on a higher contrast and pushed the luminosity to give the image an ominous look. I though it went well with the interesting and complex gas structures.

Thank for looking!

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.
