IC443/Jellyfish HaRGB

Revision title: IC 443

My experiment of shooting at my bortle 7 home continues. I did a dynamic alignment of the two channels/filters, then cropped it and applied gradient extraction then noisex, blurx. I extracted the channels from the Idas and AstronomikL2 and combined the red channels with Pixelmath using this algorithm ~(~Red * ~Ha) to give me a blended Ha channel. The red is the Astronomik R and the Ha is the Idas R. I then do a linear fit of the blended ha using the Green channel from the AstronomikL2 as reference and then do a channel combination with the G and B from the AstronomikL2 and R using the blendedha which gave me a HaRGB output. I then do a fitsheader with one of the AstronomikL2 light subs and applied it to the HaRGB output and then applied imagesolver and SPCC. I later on used the blendedHa as luminance using Lrgb combination. Thanks to @Ryan Génier for sharing this method of adding Ha to an RGB image with me.

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.
