Dust and Gas in Cepheus - vdB 152, Barnard 175, SNR 110.3+11.3 & DeHt 5

In August 2022 my friend Robert and I decided to collaborate on this beautiful target of Dust and Gas Clouds in the constellation Cepheus.
As I just switched from my Zwo Asi 2600 MC Pro to the MM Pro and only had the H-Alpha filter available at the beginning, it was clear that I will collect as much H-Alpha as possible until the other filters were shipped, while Robert was collecting all the RGB data with his William Optics FLT 132 and his QHY 268C.
In two moonless nights at the beginning of September we were lucky enough to already collect most of the data.
The missing Luminance and OIII data I just added a few days ago in another moonless night.

This target in Cepheus contains a lot of different object types in a relatively small field of view.
On the middle left of the image you can find vdB 152, an eye-catching reflection nebula in a distance of about 1400 light years, which is situated on top of the big dark nebula Barnard 175.
Glowing in red and blue, the emission nebula Dengel-Hartl 5 is located on the middle right of the image. Originally this nebula was classified as a planetary nebula because of the only blueish star in about the center of the nebula - a white dwarf.
As of today, it is likely that the white dwarf is just "making his travel" through an interstellar cloud of hydrogen and oxygen, ionizing the gas around him.
Also, the fine remnant filaments of a big star explosion are making their way through the image on top - the Supernova Remnant SNR 110.3+11.3.

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.
