Barnard 312

This object is a dark nebula located in the constellation of Scutum at a declination of -15 degrees. The object spans about 1.5 degrees in our apparent view.

Like most dark nebulae, this object is not well researched or documented in the literature. I could not find a distance estimate for this object, but at a typical dark nebula distance of 1000 light years, this object would be 25 light years wide. The tiny inky dark spot towards the top of the image is identified as both LDN 372/374, while the open star cluster just to the right of this dark spot is Ruprecht 171.

Thick dust is causing two effects in this image - obscuring the majority of the background stars in the nebula area, and creating an orangish hue in the surrounding area. The number of background stars in this region of the sky is amazing. I love the stark contrast between the deep dark black of the central nebulae area and the bright starry background of the surrounding region.

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.
