SH2-86 and NGC 6823

NGC 6823 is an open cluster of stars surrounded by a large emission nebula designated Sh 2-86 in the Sharpless catalog. The cluster is approximately 50 light-years in diameter. The cluster and nebula lie in the constellation Vulpecula at an estimated distance of about 6,000 light-years from the Earth. The stars in the cluster are very young in astronomical terms and are estimated to be only about 2 million years old. The bright central core of the cluster is composed of large, hot, type O and B class stars. The intense radiation from these stars is responsible for the distinctive shapes of the pillars, Boc globule, and mountainous clouds of the nebula. The most striking feature of the nebula is the “elephant trunk” pillar that points to the central part of the cluster. The pillars and other features of the nebula are very similar to the Eagle Nebula made famous by the iconic Hubble image “The Pillars of Creation”.

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.
