Revision title: Neural network and pixelmath

+50 hours of data and issues with flats not working left me with this mess. I think my raw individual frames were underexposed even at 600 seconds and noise took over the background. As far as I know flats stop working when the mean ADU of each sub-frame is too close to the master flat dark mean ADU.

So what I have learned from this camera is that you should avoid low mean ADU at all cost or you will be left disappointed even if the target is visible it doesn't mean the final stacked image will be amazing.

Title: Neural network and pixelmath

Description: A complete reprocess of old data that I was not proud off after spending hours upon hours imaging it. Used the new neural network based tools for noise reduction and star removal as well as pixelmath drag n drop icon sets from "AnotherAstroChannel and lukomatico".

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.
