IC443 Jellyfish Nebula

A supernova remnant (SNR) is located in the constellation of Gemini. It is commonly known as the “Jellyfish Nebula”due to it's shape.
These types of objects are created by one of the most important processes in the universe - a supernova event - when a star explodes and scatters the heavier chemical elements it has made during its lifetime back into space. This material will eventually form into future stars and planetary systems.
IC443 is thought to have been formed between 30,000 and 35,000 years ago and is located about 5,000 light years away,

I am not real happy with how I have processed this and my data was not the best, so will process again and intend to try imaging it again next time it comes back into view and get some improved data.
Nebula captured with 3 filters , Hydrogen Alpha, Oxygen III and Sulphur II. Then captured stars with Red, Green & Blue filters

Data taken over 3 relatively clear nights (rare events in Yorkshire) January to February 2022.

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.
