Image Description and Details : Located in the Cepheus constellation at 1400 lights-years, Van den Berg 152 is a blue reflection nebula near the edge of a large molecular cloud with full of interstellar dust and a star in the embedded region (BD+69 1231) giving to the edge of the molecular cloud the blue color. LDN1221 and a large tail of dust crosses the field like a comet. Image acquired through Takahashi FSQ-106EDX3 on EM-200Temma2M and Andor Apogee U16M / AFW-50-7S ccd.

Here is the last image made with the new Askar 600 scope and the 6d gun! Staying 1 week in Aveyron with the astronomical association I was able to test my new askar 600 telescope, with reducer, I go to 420mm focal length and an aperture of f3.9! Formerly I had a Newton 150 750, f4 it changes bcp! Here is a small image made on Cepheus, if it's done it's over! Here is ldn 1235 the shark and vdb 152 the magic bean from dragon ball z!!

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:

Image Description and Details :

This cosmic pillar stretches for approximately 1,400 light years along the northern part of the Milky Way, in the constellation Cepheus. Near the edge of the large molecular cloud, pockets of dust block all light from the stars in the background or weaken the light of the brightest star at the top, this star giving the nebula its characteristic blue color.At the bottom right of the image is a planetary nebula LBN 538 (red / blue).

Notes

This image took me more than 7 years to create. The first time I shot with an unmodified Canon 6D in 2013. But was not satisfied with the data after I had the opportunity to process Frank Sackenheim's CCD data of the same object (here or on Frank's homepage). In 2018 I made attempts with luminance shots in 2x2 binning with a Moravian G3-16200 (due to the bigger sensor of the Canon 6D now as 2 panel mosaic), but I have not continued this project. In summer 2020 I found this old data again, added additional Luminance-data and new Halpha- and OIII-data and finally tried to create an image with these old and new data.

The red streakes crossing the image in diagonal direction are a small part of the huge supernova remnant SNR 110.3+11.3 in the constellation Cepheus. It is one of the nearest supernova remnants and only 1300 light years away from earth. These shocked molecular gas filaments were discovered and catalogued in 2001 by John Bally and Bo Reipurth.

Van den Berg (vdB) 152 is a blue reflection nebula that glows at the bottom of a dark Bok globule called Barnard 175. Near the edge of a large molecular cloud, interstellar dust in the region blocks most of the starlight behind it or scatter light from the embedded bright star giving parts of the nebula a characteristic blue color. Ultraviolet light from the star is also thought to cause a dim reddish luminescence in the nebular dust.

Embedded in the left side of the nebula is the Herbig Haro object HH 450, a jet emitted from a newly forming star.

Dengel-Hartl (DeHt) 5 is a HII- and OIII-region, maybe an ancient planetary nebula, ionized by the white dwarf WD 2218+706 (the blue star in the center of the nebula). Beverly Lynds catalogued the brighter part as LBN 538.
