M8, Lagoon Nebula. Almost 35 hrs integration time. Sky-Watcher Esprit 120mm, QHY278M, Optolong 3nm NB, and RGB filters.
13hrs of Hydrogen data taken from downtown Bortle 9 Phoenix, Arizona. 13 hrs Sulphur split between Bortle 1 and Bortle 9, and 6 hrs Oxygen all Bortle 1, new moon. 1.5 hrs of RGB also at Bortle 1.

I did some interesting combinations of the data to get this final image. I ended up blending a Foraxx, and RGB version and a DreamPlease which has the following pixelmath equation:
R: iif(H>.15, H, (H*.8)+(O*.2))
G:
iif(H>.5, 1-(1-O)*(1-(H-.5)), O*(H+.5))
B:
iif (O>.1, O, (H*.3)+(O*.2))

I always start going down a rabbit hole with processing...experimenting with variations, then combining parts of the variations with different blends in photoshop. Then final tweaks in Lightroom.
I just like a pretty picture, with good details.

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.
