Dark shadows in sagittarius

Nice field of a region in Sagittarius full of dark areas. The main shadows looks like a dog's head with small ears. There are many Dobashi objects that I will identify soon.
The open cluster NGC 6480 is not an open cluster but rather a group or an association of stars. There is a bit more information here:
https://theskylive.com/sky/deepsky/ngc6480-object
Using database search on Simbad, it comes out that the shadow or dark nebula, sometimes is identified as a dog's head and sometimes as a horse head. It is LDN 1795, and it is in this reference:
http://simbad.u-strasbg.fr/simbad/sim-id?Ident=LDN%201795
A similar field is in AB, see for instance https://www.astrobin.com/q3c3qc/
Another view in B, rotated, is here: https://www.astrobin.com/d8phnc/?nc=user
I believe that there is an enchant on these dark formations, and in this case, the location close to the Galactic centre makes them even more special.
Looking at Lynds Dark Nebulae catalogue, J2000 coordinates, clearly LDN 10 and 12 are there.

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.
