Westerhout 5, also known as Soul Nebula, is an hydrogen region located in constellation Cassiopea, nearby other famous objects like the Heart Nebula and the Double Cluster. Its spans for about 100 light years and it is a nursery of stars, which have a few millions year old - young, compared with our 5 billion year Sun. These young stars are the large blue one and are clustered within the nebula (IC 1848, CR 34, 632 and 634). The highly energetic starts generate strong stellar wind, which push the nebula away, carving it out and creating the inward pillars we see in the photo which, due to its higher density, are also star forming regions.
The Soul Nebula shape derives from the bridge it exists between the two "bubbles" of gas. It resemblance to a fetus is the reason for also being called Embryo Nebula.

Following several weeks of bad weather, finally sky cleared for some nights which allowed me to capture 20+ hours of narrowband (NB) imagery using hydrogen, oxygen and sulphur filters, used to create a false colour SHO image. This step is one of my headaches in processing NB as it entails the most artistic aspect of astrophotography, which does not bode well a mathematical mindset... :-) Still, I think a pleasent colour pallet was achieved.

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.
