IC443 Jellyfish Nebula

Revision title: IC443 Jellyfish Nebula (Rev-1; HSO mapped to RGB )

IC443 Jellyfish nebula is a galactic supernova remnant (SNR) in the constellation Gemini in Hubble Palette. It is roughly 5000 light years away from earth.
This is my first monochrome processing attempt. I used Sirilic pre-built script to process SHO images. Once normalized Ha, SII, OIII fits images are created, then used Pixelmath in Siril https://siril.org/tutorials/pixelmath/ and tried different mixing pattern for SHO.
1 -Attempt to Hubble Palette SHO channel mapped to RGB. (First Image)
2- Also tried Hubble classic Gold with R = 0.6*SII + 0.4*Ha ; G = 0.7*Ha + 0.3*OIII; B = OIII
3- Simple RGB -> HSO mapping. (Rev1)

A lot to learn ...

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.
