NGC 6820 (Sh 2-86) and NGC 6823 - HOO Narrowband

This is a narrowband image of NGC 6820 in Vulpecula, also known as Sharpless 2-86, which was processed in HOO bicolor (Red = H-alpha, Green = OIII, Blue = OIII). NGC 6820 is a star-forming region with extensive dust embedded in a cloud of hydrogen emission nebula. The splendid open cluster above the dust pillars is NGC 6823. This nebula reminds me of a coral reef with a fish swimming through it. Seeing was excellent when I took the data, but I have not had a night of good seeing since.

The "B" revision is stretched to bring up the overall brightness of the image.

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.
