The Soul Nebula and "Little boogie man" in SHO

The Soul Nebula (also known as Embryo Nebula, IC 1848) in Cassiopeia is a young open cluster of stars surrounded by a huge cloud of dust and gas, 150 light years large, at approx 6500 light-years from Earth in the Perseus spiral arm of our Milky Way. Ii is a rich star forming region, showing several typical features (for this class) of objects: Bok globules, Cometary Globules as well as trunk like pillars, all of them different beds for star births. The cluster of stars IC 1848 lying in the center of the nebula was formed about a million years ago from the material of the nebula. Winds and ultraviolet light from the young stars are excavating a cavity in the cloud, made evident by the Oiii component of the image. Part of the cloud are more dense than their surroundings, thus being eroded more slowly and forming giant towers, or pillars of dust and gas, which all point toward the central star cluster. Material at the interior edges of the cavity is also being compressed by the winds and radiation from the star cluster. This triggers new star formation in those areas. The pillars inside the Soul Nebula are each about 10 light-years tall and have stars forming at their tips. Also, a dense dust cloud shaped like a "little Boogie Man" is curiously visible inside the Nebula.

Oiii Ha and Sii lights have been produced with Baader SHO filters for a total 25 hrs approx (Oiii/Ha/Sii=2:1:1). Finally, 2 hrs with Baader RGB for the starfield

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.
