LDN Circle between Cepheus and Draco - a high-res mosaic with 50+h integration

With many objects I know what I'm going for. Plenty of great renditions can be found on AstroBin or other places online. This project was different.

I was originally planning to go for NGC 7023, the Iris Nebula, one of my favorite DSOs. But also an object that has been imaged plenty of times - more and more I enjoy to go exploring and being surprised by the results. In the last moment I changed my mind and searched for an intriguing formation of dust nearby, simply by navigating through the DSS2 survey. There is plenty of dust clouds in this area of the sky. This particular formation caught my eye, as it has different intensities and brightness of dust clouds. The shapes around LDN 1152 and LDN 1157 gives the scene a certain “milk in coffee” dynamic structure.. On the other side LDN 1147/1148 have a wispy, blurry touch to it. I was also surprised to find the red structure near LDN 1152 isn’t a star shrouded by the dust, but the galaxy PGC2708838.
As the formation with its contrasting manner doesn’t fit into my field of view, this dusty adventure premiered as my first mosaic.
This is a 1x2 mosaic with around 25 hours of integration on each of them. The stich was performed with the PhotometricMosaic in Pixinsight. By coincidence The Astro Imaging Channel (TAIC) had had a helpful and interesting contribution by Jose Mtanous in May, which made me confident I would find my way around the processes in Pixinsight.
Also dark nebulae and dust formations still are quite a processing challenge to me, so if anyone can point me to good guides on these kind of objects, please do.

Enjoy and CS

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.
