Sh2-174 LRGB-NB

Sh2-174 or the Valentine Rose is a very faint but large Planetary nebula located in Cepheus. A planetary nebula is created when a low-mass star blows off its outer layers at the end of its life. It is almost 1000 light years away from Earth.

 

I initially started off just shooting this in narrowband but then came across several images showing all the surrounding dust. So I shot several hours of broadband data as well. I processed the NB as HOO, adding in the SII (there isn’t very much) using ImageBlend script. I then processed the LRGB data combining the two again in ImageBlend. As much time as I have in NB, I could probably use another 20 hours in Ha-OIII. Definitely will revisit this area in the future, with a different FOV.

Total Integration: 47 hours 52 mins
