LDN 137 and LDN 141

Link: http://www.jthommes.com/Astro/LDN137.htm

The large dark nebula in the center is LDN 137. Embedded in (or foreground to) LDN137 is the smaller and denser LDN 141. The less dense LDN 152 is at the top of the image. There are other dark structures throughout this image. I have annotated some of the more prominent dark structures with references to the Dobashi Catalog of Dark Nebulae and the PGCC. There are background galaxies in this field - the annotated images shows some of these. Two of the more predominant background galaxies (LEDA 917034 and LEDA 919715) are members of the galaxy group [CHM2007] 1223 - at about 350 million light years distant. These objects and some of the brighter stars are identified in the annotated image. Horizontal FOV is approximately 120 arc minutes. Full size image scale is 2.77 arcsec/pix.

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.
