G82.2+5.3 SNR

This image captures a supernova remnant (G82.2+5.3, also known as W63) superimposed over a field of HI emissions, located in the constellation of Cygnus at a declination of +46 degrees. The SNR is 5,000 light years away, with a width of about 100 light years.

The Ha emission nebulae are numerous, including LBN 313, 325, 326, and many DWB objects. These are likely behind the SNR and unrelated to it. I could not find any distance estimates for these Ha nebulae. The dark nebula designated as Barnard 345 is at the top center of the image but is very faint.

An excellent Astrobin IOTD of this region, with 160 dark sky hours of integration and an excellent description, is posted here in a collaboration by @Min Xie and others.

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.
