The beginning of a large Mosaic - Bubble and Lobster Claw Nebulae

Revision title: Reprocessed with GraXpert background extraction

I finally pulled out my second rig and started a multi-seasonal project. My widefield scope will be dedicated to taking mosaics for the near future.
The first I just started will comprise of 20 panels and cover an area between Cassiopeia and Cepheus. This does not mean I will hold back with showing some of the work done and so I present here the first 2 panels... Panel 8 (Bubble) has 65 subs and panel 13 has 72 subs

Title: Reprocessed with GraXpert background extraction

Description: I tried out this morning the new GraXpert Beta software and reprocessed the 2 panel mosaic.
I think the AI does protect the faint nebulosity better then my eyes placing boxes in the DBE. However I also started to see some gradients after stretching which let me think I might have a problem with my darks...or???

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.
