SH2-132 Lion Nebula

SH2-132, also known as The Lion Nebula, is a rich HII region with star clusters, emission nebulae, and dark dust regions. Located in the southern portion of the constellation Cepheus, the Lion Nebula is roughly 10,00 light-years away in the Perseus Arm of the Milky Way Galaxy.

I am not going to lie, this was a tough one for me. I took a short hiatus from imaging and upon my return, wanted to tackle this beautiful nebula. "It's like riding a bike" does not apply to image processing. A lot of what I had learned was forgotten. Lost of struggles processing this in Pixinsight but put my best foot forward.

Thank you for stopping by to take a look.

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.
