VdB 152, Barnard 175 & Co

Image Description and Details : Here is a rich field located within the large molecular cloud of Cepheus.
This image was an experiment under my downtown sky, and i am rather happy with the result because, although having probably approached the limits of the Bortle 7 sky, it shows that urban astrophotography still offers possibilities with this type of object.

4 types of nebulae are visible in this image, against a background of nebulosities of interstellar dust:
- the dark nebula Barnard 175, a dense pillar of dust
- the reflection nebula Vdb 152, shining a characteristic blue at the top of this dark pillar
- the old planetary nebula DeHt-5 radiating mainly in the wavelengths of ionized hydrogen and oxygen (red and blue)
- part of the SNR 110.3 + 11.3 supernova remnant whose ionized hydrogen filaments (red) cross the field

Some distant small galaxies are visible in the background despite the density of this area of ​​the Milky Way.

37h30 of exposures carried out in September and October 2021 in Amiens (Bortle 7) through LRVB filters supplemented by H and O filters for NP and supernova remanence with:

newton 250mm f / 3.8
CEM120 mount
Camera ZWO ASI 2600mm

Processing with Pixinsight and Photoshop.
