NGC 6823 and Sh2-86 in HaRGB

This star forming region contains a huge pillar of dark dust, pretty similar to the well-known Elephant Trunk nebula (IC 1396A).

The hydrogen gas in Sh2-86 is illuminated by bright blue stars from the young open cluster NGC 6823. The radiation from these stars also erodes the surrounding gas and dust, which creates these interesting dark pillars and Bok globules.

From my light-polluted site, the dim nebulosity is almost invisible in RGB, but shows up reasonably well with the hydrogen alpha filter. I made the HaRGB composite using the NBRGBCombination script. For framing, I decided to include some of the colorful bright stars around the nebula.

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.
