NGC 6820 and NGC 6823

I noticed the nebulosity of NGC 6820 while steering the telescope across this area with Stellarium. I was so fascinated by the nebulosity that it didn't even realize that there was also an embedded open cluster, NGC 6823. I took two images of this field, each with a different exposure length. This first image, a stack of shorter 30-second exposures, looks better to me because the stars are not as overexposed. A faint satellite crossed the field during one of the exposures, leaving a vertical trail across this image. If anyone knows how to identify this faint satellite, please leave a comment! It passed through the field on 2019-09-24 between approximately 03:36 and 03:41 UT.

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.
