Situated against the vast cosmic tapestry, Sh2-174 reveals itself as a region of ionized gas, its luminous glow painting a portrait of stellar activity within its nebulous embrace. Though the exact distance remains a cosmic secret, this celestial spectacle offers a glimpse into the intricate dance between interstellar elements and the stellar forces that shape the universe.

The ethereal hues of Sh2-174, likely fueled by the presence of ionized hydrogen, present a captivating display of cosmic alchemy. As astronomers peer into its radiant depths, they embark on a journey to unravel the mysteries concealed within this celestial ember, probing the secrets of starbirth and interstellar dynamics.

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.
