G156.2+5.7_Banner.jpg SNR G156.2+5.7 is a faint and evolved supernova remnant located in the constellation Auriga.

This image attempts to reveal the delicate shock fronts forming a large, nearly spherical shell as the expanding remnant interacts with the surrounding interstellar medium.

G156.2+5.7 is estimated to be about 10000 years old and lies at a distance of around 5500 light years.

I was not aware of the H-alpha filaments in the bottom right corner of my image and they kind of interfered with my framing but I also didn’t want to crop them out. I’m curious if they are extended structures of G156.2+5.7 or belong to something else.

As always, more data would’ve been great but it’s time to move on before galaxy season kicks in!

Thanks for looking and clear skies!
