LDN 564

This image is centered on the dark nebula LDN 564, located in the constellation of Serpens at a declination of -1 degrees. Surrounding LDN 564 are numerous other obscure dark and bright nebulae.

I saw this portion of the sky in the Aladin sky atlas program and was intrigued by the combination of dark nebula, bright stars, and dense star fields in this part of the Milky Way

Some of the designated object highlights here includes the small dark nebula Barnard 316 in the lower left corner and the red emission nebula Sh2-64 in the lower right corner.

I like the thin, inky black, winding dark nebulae in the top portion of the image. It is interesting to me that, of all of the dark nebulae seen in this image, the only one to make Barnard's list is the tiny one that is B316.

I am also fascinated by the dim undesignated ‘H’ shaped light nebula at 18:34:44 RA and -00:56:37 DEC.

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.
