Description

This image is the sum 1100 60 secs unguided subs taken during the nights of the 25th, 26th, 27th of July 2020. Imaging train was Newton 250 F 3.9 Orion USA, QHY183 mono, Baader 45 nm ha filter, Baader MPCC coma reducer, on top of an Ioptron CEM60EC.

Aquisition was done with Astroart. Processing with Astroart, Pixinsight and PS. I have tried to use Pixinsight DBE in order to reduce the heavy gradient that was in the stacked image. But I still have to study a lot in order to get decent results with this software.

vdB 152 is a reflection nebula visible in the constellation of Cepheus.

Its position is located about 4 ° east of Alfirk (β Cephei), in a region rich in dark nebulae and star fields, located on the southern edge of the Cepheus Flare; inside it is a blue-white star of main sequence, BD + 69 1231, of magnitude 9.29, whose radiation gives the surrounding gases a distinctly bluish color. The star is located on the southernmost end of a cometary-looking dark nebula, with a long coma that disperses to the north. In the northern part of the cloud is LDN 1217, a very dense cloud in which the presence of different sources of infrared radiation suggest the presence of star formation phenomena. The distance of the structure is estimated at 400 parsecs (about 1300 light years). (italian wikipedia page translated with google translator)
