SH2-157 widefield at the Cas / Cep border

As is well known, there is a vast amount of beautiful night sky objects in the constellation of Cepheus(Cep) and Cassiopeia(Cas). I centered this image on NGC7510 aka "The Dormouse Cluster" to capture 50:50 percent of both constellations' regions.

I used my unmodifiedCanon EOS 7D (1st version, 12+ years old) with a CLS clip-in filter. After 5 hours of integration time, post processing was still very challenging for me. I took this image already this September but only yesterday, after one more of a couple of fresh start-overs and rejects, I could achieve what you see here.

My images of HII regions always seem to lack 'transparency' or a 'feathery lightness' ... suggestions for improvement are highly appreciated.

Description: During my years as a pure visual observer (i.e. no astrophotography), I used to prepare my observation nights with printed maps like Uranometria or Sky Atlas 2000.

After these observations, I often fleshed out observation reports together with sketches and captions. It was (and still is) one of my ways to relaxation.

This elaborated image version is thus a reminiscence on that time.

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.
