I was never happy with my initial NGC 7129 result but it was the best I knew how to do at the time. Thankfully things have changed both with me and with the tools and this time I was able to bring out a lot more detail and produce a much more pleasant image! The 2021 image had Ha added to it but the 2023 drops the hydrogen because it really didn't seem to be adding anything.

Here's how I processed it in 2023:

L:
dynamic crop
blurXterminator
starXterminator
noiseXterminator
GHS

RGB:
channel combnation
ABE
SPCC
blurXterminator
starXterminator
noiseXterminator
GHS
LRGBCombination (adding L)
Used GAME and GHS to reduce some star halos
HDRMultiscaleTransform
LHE
Curves (contrast)
MLT (very mild sharpening)
pixel math in stars

L stars:
ghs

RGB stars:
ghs
lrgbCombination in L stars
unsharp mask (very mild sharpening)

Here's how I processed it back in 2021:

L:
dynamic crop
deconvolution
ABE
MLT noise reduction
histogram transformation

H-a:
dynamic crop
MLT noise reduction
histogram transformation

R, G and B:
dynamic crop
ABE
MLT noise reduction

RGB:
channel combination
background neutralization
color calibration (PCC refused to plate solve the image though the coordinates were correct)
histogram transformation
LRGBCombination
NRGBCombination to add in h-a
EZ Star reduction script
LHE (2 scales)
curves (contrast)
Adv Sharpening script

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.
