LDû 2–named after Pascal Le Dû - in Cygnus (Rings of Fire)

While shooting an ultra wide-field in Cygnus I came across this area that I have not seen before. I decided decided to use another scope (my 600mm) to study it a bit more.

At the time I didn’t know what it’s called but I thought it’s pretty cool, especially the ring near center. I later found out the name and that it was previously discovered by Pascal Le Dû.
As I built time on it and processed the data I decided to keep adding more time. I shot it in SHO but the signals are quite weak. So this is mostly HSS palette as Oii is virtually non-existent. I'd like to call it, Rings of Fire. There are a few rings in the detail, just to the left of the larger ring. Check it out and you'll see.

Shot from my backyard, Bortle 8. Processed in Pixinsight.

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.
