Sh2-132 The Lion

This beautiful HII region in Cepheus is ionized by a dozen of OB stars of Cepheus OB1 association and two Wolf-Rayet stars, WR152ab and WR153. A variable star RW Ceph, one of the association members, is one of the largest known stars: it has about 1000 times larger diameter then the Sun. [1][2]
A small planetary nebula PN G101.5-00.6 can be found in the bottom-right.
Please, see the annotated version.

Initially I've started processing this image as a conventional RGB=SHO. But very soon I've got so much excited with the effect of nonlinear channel mixing that it took me several days to stop playing the levels sliders.
Hope you like this image the way I liked working on it. Wish everybody clear and peaceful skies!

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.
