This is a narrowband image in SHO palette with RGB stars replacing the narrowband stars.

SH2-86 is an emission nebula located in Vulpecula. It is ionized by the open cluster of blue stars, NGC 6823. Numerous sources refer to the whole nebula incorrectly by the name NGC 6820, which is actually only the small reflection nebula in the lower center part of the image.

The intense radiation from the central stars is responsible for shaping the pillars, dark globules and towering clouds of the surrounding nebula. The most distinctive feature of the nebula is the “elephant trunk” pillar that points to the central part of the cluster.

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.
