Simeis 147- "The Spaghetti Nebula"

Definitely one of my most difficult targets. This 4 panel mosaic, imaged during the new moon of January 2016 represents an extremely large area in Aurigu and Taurus. Remnants of a giant explosion some 40,000 years ago. Easily located by one of the brightest stars in the winter night sky, Capella. This structure has a diameter of 3 degrees in the night sky. For comparison, the full moon constitutes 1/2 a degree. The faint hydrogen structure remains unseen with the naked eye.

More information from Wiki: Simeis 147, also known as the Spaghetti Nebula, SNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations Auriga and Taurus. Discovered in 1952 at the Crimean Astrophysical Observatory using a 25-inch Schmidt-Cassegrain telescope, it is difficult to observe due to its extremely low brightness.

The nebulous area is fairly large with an almost spherical shell and 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.

It is believed that after its stellar explosion a rapidly spinning neutron star known as pulsar PSR J0538+2817 was left behind in the nebula core, emitting a strong radio signal.
