Dark Nebula Barnard 150 - Seahorse Nebula

Barnard 150 is a dark nebula, also known as the Seahorse Nebula, located in the constellation Cepheus. It is about 1,200 light years from Earth. The nebula is so thick that it absorbs all light from stars behind it, making it stand out against the background of the Milky Way.

The nebula is shaped like a seahorse and is visible in silhouette against a background of stars. It has three dense dust cores, which are star formation regions. These cores were cataloged by Lynds and named LDN 1082 A, B, and C. This is almost 6.5 hours of collected light.

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.
