Ring of Cygnus

I found out about this object from a couple of sources. Recently, Joe Navara (Joe's Astrophoto) did a segment about imaging the "Rings of Cygnus" - he credited Tommy Lease, (colorado_astro) who posts here on AstroBin, although I was unable to locate his version of this image. I have also seen this referenced as the "Cosmic Lasso" imaged by the Finnish astrophotographer J-P Metsavainio on his website "AstroAnarchy" in 2015 who noted the structure while piecing together his mosaic of the entire constellation of Cygnus.

I'll just call this the "Ring of Cygnus" - an interesting, but somewhat faint object that is prominent in structure in both Ha and SII with only a background of faint OIII clouds. Taken primarily with my RC-8 to capture details of the structure while the majority of the background OIII was taken with my SVX-102T.

Imaged over several nights: May 18, 31; Jun 1-2, 10; and Jul 8, 2023.

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.
