This is my first narroband image. I have changed my entire setup to narrowband. Still learning, but pretty happy with the result so far.

my processing pipeline in pixinsight after integration:

1- combine with pixlmath R= h, G= 0.3*H+0.7*O, B=o
2- dynamic crop
3- DBE
4- very soft MLT on luminance channel
5- histogram stretch
6- Arcsinhstretch
7- motion deconvolution to fix stars
8- remove stars (starXterminator)
9- TGV denoise
10- further denoise ATrouswavelet Transform (strongly masked image)
11- color saturation on nebula
12- desaturate the stars
13- add back teh stars (pixelmath)
14- deconvolution (parametric PSF) to tighten up the stars
15- MLT sharpening

I had a few hours of RGB as well, but I liked the narroband data much better!

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.
