SH2-132 Ha Oiii RGB

SH2-132 in Hubble Palette

SH2-132 is a faint emission nebula that is approximately 10,000 light-years away from Earth.
Also known as The Lion Nebula, SH2-132 is a concentrated HII region with star clusters, emission nebulae, and dark dust regions.
The Nebula is located in the southern portion of the constellation Cepheus.

I started collecting data for this image almost a year ago and recently added more Oiii data using my newly acquired Optolong 3nm filter
I used the HOO Normalization Script in Pixinsight to convert the HOO combination to 'SHO' (Thanks again to Bill Blansham for his 'genius' Pixelmath)
A lot of colour masking and subtle curves work was required but well worth the effort.
RGB Stars were masked in after processing and then colour boosted.
I decided to crop the image quite a lot into a square format to focus attention on the dust structures.
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.
