The Lion Nebula, Sh2-132, In Narrowband Bi-Color

This is most of the Lion Nebula, Sh2-132, in narrowband bi-color, with RGB stars. My camera orientation was not optimal, so could not capture the entire structure of this fascinating object., but still got enough to evoke the likeness of the lion, I think.

This is an emission region in the constellation Cepheus, guesstimated to be between 10,000 to 12,000 light-years away, in the Perseus Arm of the Milky Way. I am particularly fascinated by the 'searchlight' feature that appears to emanate from inside main the Hα region of the nebula.

The 'mix' for this palette was:

Red = (1.3 x Hα)

Green = (0.7 * OIII) + (0.3 * Hα)

Blue = (1.2 * OIII) + (0.2 * Hα)

with rescale enabled.

Thanks for looking, and any comments, questions or critiques are welcome.

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.
