Barnard 312 - The Black Manta

After months, a row of clear moonless nights showed up, giving me eventually the opportunity to portray this beautiful dark nebula on thick stellar background that has been on my wish-list since long.

B312, with its characteristic manta fish shape, lays 17 degrees away from the galactic center in Scutum, just across the border with Sagittarius. I found no distance estimates, but, assuming it stands in front of a star cloud located at the same distance of the neighbor M24, it has to be closer than 10000 ly. If it lays between 1000 and 3000 ly away, then its diameter should be in the range of 17 to 50 ly.

In the upper right corner is visible the reddish Sh2-50 region, also known as LBN66.

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.
