Sharpless 132 - The Lion Nebula

Sharpless 132 is a faint emission nebula at the Cepheus/Lacerta border, located 10,000 to 12,000 light-years away from Earth, thus placing itself inside the Perseus Arm of our galaxy. It is also known as the Lion Nebula due to its resemblance to the king of the jungle. I see two lions in this Nebula, one at peace and another roaring.

The stars responsible for the ionization of its gases are two Wolf-Rayet stars, HD 211564 (WR 152) and HD 211853 (WR 153).

It took me 6 nights to capture the data, almost equally split between Ha and Oiii. This is my longest project to date, but I am not sure my processing skills are worthy of it yet. It's not an easy target to process. It is also the first time I've used the reducer, which I have yet to figure out the correct spacing.

Comments and feedback are much appreciated.

Clear 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.
