Here is an additional attempt of post processing this narrowband image. This one has been a real challenge for me but I do like the color palette on this post processing.

NGC 6820 is an emission nebula that surrounds open cluster NGC 6823 in Vulpecula, near M27, the Dumbbell Nebula. The nebula NGC 6820 is also called Sharpless catalog Sh 2-86.

The most striking feature is the trunk-like pillar of dust and gas protruding from the east side of the nebula towards the open cluster, NGC 6823 in the west. The center of the open cluster is about two million years old and is predominantly represented by many young, bright blue stars. Outer parts of the cluster intimately involving pillars of emission nebula NGC 6820, contain even younger stars. The huge pillars of gas and dust are probably formed when surrounding gas and dust is pushed and eroded away by radiation from nearby stars. Remarkable dark globules of gas and dust are also visible in the nebula, much as is seen in the better known Eagle Nebula in Serpens or the Lagoon Nebula in Sagittarius.

Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away.[2] It forms the core of the Vulpecula OB1 stellar association.[3]uch noise reduction; but may leave it alone for now.

Upon looking at posted image I decided since I had a better handle of ACDNR I decided to go back and correct the noise reduction problems I created in the past for this image. I also applied Frank's tips and tricks using SHO palette in Photoshop.

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.
