SH2-119 pearl in the clamshell?

The Clamshell Nebula has a pearl! should have named this the Oyster Nebula. This seldom imaged nebula is a large complex of emission nebulosity in Cygnus constellation, about 2 degrees east of the North American Nebula. The pearl is 68 Cygni, mag 5. It lies in a rich star field which I reduced significantly...to bring out the nebula.

This image is RGB with blended Ha. No luminance. Shot over 2 nights at my dark site, bortle 3-4. Proved to be a difficult target to process for me. I will work on using Ha as luminance and post as a revision for comparison.

Description: Ha as luminance for comparison. I like the original no luminance better.

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.
