I reprocess this data with the recently learned techniques to good effect!

Here's what I did:

S, H and O masters:
dynamic crop
deconvolution
starXterminator (creating stars)
histogram transformation

SHO:
channel combination (SHO)
histogram transformation to line up peaks
extract luminance as lum
TGV Denoise
channel combination in lum
curves for contrast
pixel math in stars (max)

lum:
TGV Denoise
LHE (2 scales)
MLT sharpening

stars:
channel combination of stars created by starxtermitor (SHO)
histogram trasformation

original description for rev A below
--------------------------------------------------------
I can't really say anything about M16 that hasn't been said better elsewhere. I chose the SHO palette for this in homage to the classic Hubble Pillars of Creation image which introduced many of us to the SHO palette. Of course, our telescope can't complete with Hubble for detail but it costs an awful lot less!

Processing steps:

H:
dynamic crop
MLT noise reduction
deconvolution

O, S:
dynamic crop
MLT noise reduction
deconvolution
linear fit to H

SHO:
channel combination (SHO)
Invert, SCNR, Invert (to reduce magenta in stars)
Histogram transformation
Adam Block's star de-emphasis (two rounds)
LHE (2 scales)
Dark Structure Enhance scirpt
Curves (contrast)
Adv Sharpening
Dynamic Crop to final dimensions

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.
