SH2-174 : Valentine Rose Nebula

Image Description and Details :

I'm very proud to present this photo in L-HOO which required a total exposure of 27 hours per 20 minutes per photo, spread over 7 nights of the month of May, not counting the 10 hours of image calibration. At a magnitude of 14.74, it is very little luminous, which makes it difficult to image it.

It is located in the constellation Cepheus at a distance of 980 light-years.
Sh2-174 is one of the oldest planetary nebulae that is more unusual because the white dwarf is not in the center of the nebula. This asymmetry is due to the interaction of the planetary nebula with the surrounding interstellar medium.
