Soul Nebula in HSO

This is the Soul Nebula, shot over six nights in October 2023 in HA, OIII and SII, with almost 42 hours of integration time and drizzled 2x. It seems we've had fewer clear nights this year and it was awesome to have it clear this last week. I recently switched to Pixinsight for editing and I finally feel like I'm starting to get a good workflow. For narrowband, I follow this basic workflow:

WBPP stacking
Dynamic Background Extraction
BlurXterminator
Combine narrowband channels with PixelMath
SPCC for star color
Remove Stars
Generalized Hyberbolic Stretch, several iterations
Star Reduction
Add stars back with pixelmath
NoiseXterminator

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.
