Revision title: Reprocessed from raw frames

My first try with a Mosaic. Practicing for upcoming collaborations in DK.
It's surprisingly difficult to get things to a decent result, combining multiple images gives new challenges with colors, backgrounds etc. etc. in the final image.

This came out fairly ok. Lot's to learn.

Description: Completely reprocessed.
I stumbled over Bill Blanshan's work and used his Narrowband Normalization tools, developed with Mike Cranfield.
Find the processes here on Mikes website - https://cosmicphotons.com/scripts/
Bill's youtube channel can be found here - https://www.youtube.com/@anotherastrochannel2173

I also used the Starreduction process they made.

I used the Substitution script https://www.youtube.com/watch?v=WWpAQThKOPI to selectively apply HDRMT in my image.
I am much more satisfied with this result.

Description: Not being satisfied with my previous revision, I restacked and reprocessed the image again.
This time, I managed to NOT blow out the core of the Lobster Claw, much better control the bubble and overall I believe this revision is a lot more balanced.

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.
