LDN-1622 The Boogeyman Nebula

Lynds' Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas
only easily seen in long telescopic exposures of the region. LDN 1622 lies near the plane of
our Milky Way Galaxy, close on the sky to Barnard's Loop, a large cloud surrounding the rich
complex of emission nebulae found in the Belt and Sword of Orion. But the obscuring dust
of LDN 1622 is thought to be much closer than Orion's more famous nebulae, perhaps only
500 light-years away. At that distance, this 1 degree wide field of view would span less than
10 light-years. Its foreboding appearance lends this dark expanse a popular name, the Boogeyman Nebula.

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.
