Barnard 150

This object is a dark nebula located 1200 light years away in the constellation of Cepheus at a declination of +60 degrees. It is about 1° in length, which corresponds to an actual length of about 20 light years.

Barnard 150 is the 150th entry in the Barnard catalog of 182 dark sky nebulae, cataloged in the early 20th century by astronomer Dr. E. E. Barnard (known as “the man who never slept”). This object is also known as the 1082th entry in the 1802 member Lynds Dark Nebulae (LDN) catalog, published by US astronomer Dr. Beverly Turner Lynds in 1962.

Dark nebulae are interstellar clouds so dense that their dust grains obscure the light from the background stars. Note that the dim stars which are just barely visible through the dark nebulae are primarily orange, since starlight in the bluer wavelengths is more easily reflected. Astronomers believe that star formation is taking place in the inner regions of these dark nebulae.

This object is nicknamed the Seahorse Nebula. Unlike many named sky objects, this nickname is easy to visualize in the image and does not conjure up strange thoughts in my mind (e.g. Deer Lick Galaxy, War & Peace Nebula, etc.). So it is one of the few nicknames I enjoy.

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.
