B150 (Seahorse Nebula LRGB)

Barnard 150, also known as Seahorse Nebula, is a dark molecular cloud of dust in Cepheus constellation, so thick, that it absorbs all the light that comes from the stars behind it. This molecular cloud is part of our Milky Way galaxy, one of the 182 objects cataloged by astronomer Edward E. Barnard and it lies at about 1200 Light Years away.

Due to all of the light emitted from these stars, the distinctive, serpent like shape of this molecular cloud can be observed. And with rotation of the image by 90 degrees, one can easily recognize why this cloud inherent a second name of "Seahorse Nebula". This nebula is about 1 degree in size, width of two Moons. What is also interesting about this cloud, as it have 3 highly dense dust cores, which actually is a star formation regions. They were cataloged by Lynds and named LDN 1082.

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.
