IC 443, why a Jellyfish is hard to catch

I have been struggling with this one for over a year. Shot in February 2023, I never got a decent picture out of my data. Beginning of this month I took the plunge and subscribed to Adam Blocks ‘Fundamentals’, including the Stretch Academy and that was really an eye opener when it comes to explaining how GHS works. Given that I kept struggling with this picture I decided enough is enough, and so here it is for your open feedback.

Then I looked up IC 443 in SkySafari and noticed it is only magnitude 12… So I just need much more data, like 9 hours instead of 4 1/2, and probably another camera as I think this is bit out of its league for the IMX183.

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.
