IC 1871 & SFO 12 • Inside the Soul Nebula in HOO

I processed a SHO version of IC 1871 & SFO 12 about a month ago. I decided to reprocess it in HOO with a more natural palette.

This image shows a few groups of bright rimmed globules that are collectively catalogued as IC 1871 on the right and SFO 12 on the left. Their gaseous forms are sculpted by the UV radiation and stellar winds from many hot young stars in the star cluster associated with the Soul Nebula. The term "bright rimmed" arises from the side of the globules that are facing the ionzing source exhibiting bright rims as a result of the gas and dust becoming more compressed and denser and therefore brighter than the surrounding material.

SFO stands for "Sugitani, Fukui and Ogura", the surnames of three Japanese astronomers who compiled the SFO catalogue of bright rimmed globules in HII regions. It was published in 1991 (northern hemisphere) and 1994 (southern hemisphere) by Koji Sugitani, Yasuo Fukui and Katsuo Ogura and has 89 in total.

Description: I ended up tweaking it a bit. Was a bit too orange for me. With the HOO palette I try to be as natural as possible usually.

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.
