M16 Eagle Nebula

The Southern sky is full of wonderful targets like the Eagle Nebula, unfortunately at home most of it is blocked by neighbors' homes and trees. So lately I've gotten used to traveling to my club's dark sites to capture these targets. This one was captured over three such nights. I'm still trying to figure out which is my favorite SHO pallet so I may continue to work on it, but I'm happy with the data I captured and the processing so far.

I accumulated 157 X 300sec SHO subs (Ha*63, Sii*32, Oiii*62), one after the other for background consistency and dithered for noise management.

Stacked in DeepSkyStacker and calibrated with darks, flats, and dark flats.

PixInsight workflow:
Automatic Background Extraction an all channels
EZ Soft Stretch on Sii and Oiii
Ha - EZ Deconvolution
Manual stretch
NoiseXTerminator
Combined SHO with PixelMath - Hubble Pallet
SCNR Green 75%
Combined SHO with PixelMath - Foraxx Pallet
Combined 50% Hubble + 50% Foraxx for final image
Added Ha as Luminance with Chrominance Noise Reduction
Local Histogram Equalization
Dark Structure Enhance
EZ Star Reduction

Photoshop workflow:
Cropped edges
Camera Raw Filter
Vibrance
Dehaze
Color Mixer Hue adjustments
Color Mixer Saturation adjustments
Final histogram touchup

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.
