Van Den Berg 152: Dark Nebulae Complex

Object Information:

This enigmatic cloud of dust in the constellation of Cepheus has some interesting things going on in it. The blue patch at one end is caused by the dust reflecting the light of the bright bluish star entering the cloud, apparently as a chance encounter. The very dark area immediately to the left of this is a thick knot in the cloud which is dense enough to prevent any light from beyond from being seen. Further to the left the dust grows less dense, and we begin to see stars shining through, and the dust itself takes on a reddish, rusty color. This color is due to the fact that the the dust preferentially allows light of longer (i.e., redder) wavelengths through, while blocking light of shorter wavelengths. The source of this back lighting for the cloud is the overall light from our Milky Way galaxy (Source: Dr. Adolf Witt of the Dusty Astrophysical Research Group at the University of Toledo)

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.
