Sh2-132 - The Lion Nebula

Lions and Wolf-Rayets and Clusters, oh my!

The Sh2-132 complex - also known as the Lion Nebula - lies near the border of the Cepheus and Lacerta constellations and contains a veritable zoo of deep sky objects, including two Wolf-Rayet stars, a planetary nebula, at least four open clusters and, of course, the King of this space jungle: the large but faint emission nebula presenting in the shape of a cosmic lion.

I decided to devote substantial time (almost 70 hours!) to this target to bring out as much detail as possible in the rich center, as well as the outer nebulosity at the edges of the frame. Was it worth it? I'm not sure.

The O3 is quite strong and the S2 around the edges of many of gas clouds offers nice details, especially near the "back" of the lion's head. With such a zoo of activity in this FOV (including a very dense star field), I tried to bring out a wider range of colors (I think covering the entire visible spectrum) in a way that still looks natural to my eye. I scrapped many versions before settling on the above colors in this Hubble palette combination.

I hope you enjoy. Comments and thoughts are always 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.
