Today, I want to present you my most elaborate project so far. Over several nights, locations (south of Berlin - Bortle4 area, Berlin - Bortle 7/8 area, South Tyrol - Bortle 4 area), and setups I collected more than 21 hours of lights from this very faint object in the constellation Cepheus - the Wolf's Cave nebula also known as VdB 152. Max Wolf assistant, August Kopff, discovered this beautiful nebula in October 1908. Max Wolff interpreted the structure as a cave formation in the Milky Way. So, it became known as Wolf's Cave Nebula.
The image is a combination of several dual narrowband frames taken with the Optolong Ultimate filter and RGB frames. The Ha and OIII data are used to emphasize the huge supernova remnant SNR 110.3+11.3. The structures are very faint which requires to integrate many single frames to see the all interesting objects - the more the better
.
I hope you like it. Every comment is highly appreciate.
