An amazing target that I had not known about until I did a great collaboration with Kurt Zeppetello and Joe Navara, Between us we collected almost 72 hours of SHO data to produce this image. Kurt has also posted this so I have cropped in a bit to show it a little differently.
We had a lot of fun working together and we all have YouTube channels where we made a little sketch to have some fun and tell a story of this capture. Please come and take a look and say hi.
https://youtu.be/89nziSirfkISh2-174 or the Valentine Rose Nebula (PK 120+18.1) was originally thought to have been a planetary nebula with ionized hydrogen and oxygen but one of the issues was that no white dwarf progenitor star had been found. Finally a white dwarf was discovered in the central portion of the
blue region. It is the small
blue star south of the very large white star in the top of the
blue region. Most PNs have the progenitor star in the centre but this one was offset so it was suggested that the strong tidal nature of the area blew the gases away from the star. However, a 2008 doctoral student discovered the star is much older than the nebula and could not have caused it. So the new hypothesis is that the white dwarf is merely passing through the ionized hydrogen cloud. The nebula is located about 950 light-years away in the constellation of Cepheus.
