LBN 7 and LDN 43

Link: http://www.jthommes.com/Astro/LBN7_LDN43.htm

This image shows a region of interstellar material and dust illuminated by nearby stars as well as dark nebulae of dust blocking the light from background stars. The illuminated dust structure is LBN 7; the dark nebulae are Dobashi 74 and LDN 43. There are four parts to LDN 43 (plus S, D, and E). The annotated image doesn't indicate these four separately - just the overall structure. Within the LDN and LBN structure are two cometary nebulae GN 16.311.3 and GN 16.31.7. A cometary nebula is a descriptive term for these and similar nebulae since the nebula has the shape of a comet. There are several background galaxies in the image (6dF J1634296-152207, 6dF J1633551-153149, 2MFGC 13265, and others). These objects and some of the brighter stars are identified in the annotated image. Horizontal FOV is approximately 88 arc minutes. Full size image scale is 1.89 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.
