NGC 6823

This is my evil looking just in time for Halloween image. To me it looks like a portal to the dark underworld with fiery pillars pointing the way. In reality, it's a starless NGC 6820 done in SHO.
At the center resides a star cluster that appears to have eaten out the surrounding gas. The pillars appear to be very similar to those in the Eagle Nebula. They are all pointing in the same direction of the cluster. There is even bright star formation at the tips of some pillars, again as in M16.

Description: Ok I'm done with the Halloween references, but now onto real images. This is a HaSHORGB image. The stars had been photometrically calibrated before adding to the stack.

Description: This image has been very problematic to process. There was very little signal in the SII and especially the OIII channels. That resulted in a very poor final result. Way too much noise and streaking. I just couldn't get that stuff out. I'm only posting this because it is at least better than the previous versions.

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.
