Processing steps performed below

Stacked, Aligned, and Integrated with PixInsight WBPP

Crop applied to each channel LRGB

DBE applied to each individual frame

EZ ProcessingSuite Noise Reduction

RGB CombinationRGB Stretch using a combination of ArcSinh and Histogram Transformation

Lum stretch using ArcSinh

RGB Photometric Color Calibration and Background Reduction

SCNR

Masked color reduction of the "glow" around the galaxy, which was blue for some reason (more blue data than other channels so makes sense)

HDR with Gaussian 11 applied to Lum channel

Lum combination with RGB with Noise Reduction ticked

DarkStructureEnhance

Masked contrast adjustments to brighten galaxy but not core

Curves adjustments and saturation adjustments with masks protecting background

Photoshop Steps

PS Plugin AstroFlatPro

PS Plugin APFR for sharpening

PS Plugin StarShrink

Topaz Noise Reduction with masks applied to only target the galaxy, and large diffraction stars, Topaz always ruins small stars and makes them look super weird imo.

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.
