Actually the NGC designations are only valid for the brights parts of the inner shell of this interesting emission nebula. The nebula itself is the result of a gas-ejection of the central star. It is very rich in nitrogen because the star burns hydrogen into C, N and O. This inner shell is probably colliding with gases of earlier ejections. The outer, blue, oxygen-rich shell is far older and already interacting with the interstellar medium. Despite its appearance it is not a planetary nebula which are created when "dying" stars shed the outer gas shells.

I could capture it in the same field of view as the "Dragons of Ara" NGC 6188". This is a separate rendering with dedicated processing. The full dragons image is still a work in progress. Considering the small aperture and the fact it wasn't in the center of the field, I was surprised at the detail visible.

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.
