Description

This two-panel mosaic was taken under rather difficult conditions with the moon partially up, a snow-covered ground brightening the sky and poor seeing due to ice crystals in the air, so a wise person would probably not have aimed at this very faint object. But given the circumstances I am rather pleased with the result.

From Wikipedia: 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. 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.
