Between the really bright ring, the faint halo that also shows colors and the brightness difference between the O-III and H-alpha emissions, I've tried and failed at least 10 times to adequately process what I believe is actually quite good data. This time I just totally disregarded any semblance to "true colors" or the visual appearance of the object and just went for a striking colourful effect. While I still think that something more "realistic" lurks in my data somewhere, I believe this is interestingly "different" enough to be presented.

The RGB-only data in Revision B shows a more classical rendition.

Addition from 25.02.2024: I finally managed to bring out the halo without killing all detail in the center.

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.
