Sh2-132, The head of the Lion in SHO

On the search for a less commonly photographed object, I came across the Lion Nebula (Sh2-132). Thinking if I should try to capture it with a wide-field setup, I chose to image with my SCT at its native focal length of 2000mm. If I'm interpreting the shape of the whole nebula correctly, I've imaged the Lion's head and mane.

The dark nebula close to the left of the image center is designated as LDN 1161 and the area at the top left as LDN 1163.

I was hoping to collect at least 7 to 8 hours for each filter. However, despite having very clear nights with very good seeing, fog regularly arrived after 2am/3am making the telescope to capture two nebulas in a single night.
To compensate for the loss of time, I've chosen to run the camera at 4x4 binning to increase SNR and still I have an image scale of close to 1"pp.

Contrary to my other images, I've employed some star reduction (successfully, I hope) to enhance the effect of the nebula.

As usual, I hope you enjoy and feel free to comment.

Clear skies!

Description: This revision is an SOH color blend. The contributions are R=(90% SII, 0% OIII, 10% Ha), G=(58%SII, 17%OIII, 25%Ha) and B=(0%SII, 44%OIII, 56%Ha). I'm taking the path with PixInsight now. I reworked the image in PI and did some final touch in Affinity Photo.

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.
