A Ghost Processed on Halloween (Sh2-136 in LRGB)

SH2-136 - The Ghost Nebula in LRGB
Although it wasn't a dark night when my camera caught this apparition, it was a dark and strormy night when processed on Oct 31. Such ghosts take a long time to appear, and even a single long exposure may not reveal its presence to you. One has to keep both one's mind and shutter open.
Planewave CDK12.5 - AIS6200MM
A-P 1100 GTO AE, Antlia Pro BB filters
Lum: 120 x 180s exposures, Bin 2, Gain 100
R,G,B: (3 x 90 x 240s exposures, Bin 2, Gain 100)
Total Integration Time = 24 hours

SH2-136 is referred to as a globule - I think becuase it is just a globule of dust. There are serveral stars embedded within and around the globule that are eroding its integrity with radiation - creating fingers in the clouds and creating its ghostly shapes. Some of the clouds form an opaque veil over the stars.
At least that's how scientists explain it. The supernatural explanation is much more interesting.

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.
