Also known as Simeis 147 and the Spaghetti Nebula, SNR G180.0-01.7 ,
is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations Auriga and Taurus.
It was discovered in 1952 at the Crimean Astrophysical Observatory by Grigory Shajn and his team using a Schmidt camera and a narrowband filter close to the Hydrogen Alpha transmission line.
It is difficult to observe due to its extremely low brightness.

The nebulous area has an almost spherical shell and a filamentary structure.
The remnant has an apparent diameter of approximately 3 degrees, an estimated distance of approximately 3000 (±350) light-years,
and an age of approximately 40,000 years.
At that distance, it spans roughly 160 lightyears.[WIKI}

This faint nebula has about 100 hrs of imaging data taken over a few months!
