After toying with various renditions of this highly popular imaging target, I decided to see what was behind the artistic door.

By a simple mathematical model, the RGB data allowed stripping the continuum-radiation component from the HSO images, and those corrected narrowband components were used to create this image. The HSO were mapped to their respective RGB contributions, and the resulting image was photometrically calibrated. In the resulting image, the stars were isolated from the nebula, and nebula's the hue, saturation, sharpness, etc., were adjusted separately.

BTW, it kind of looks like a fish to me, with lips that appeared on Jimmy Kimmel's show a few days ago. Or, maybe those lips introduce the Rocky Horror Picture Show?!

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.
