Sh2-240 - Spaghetti Nebula

From Sky and Telescope: Simeis 147, also known as the Spaghetti Nebula, 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 by Grigory Shajn and his team using a Schmidt camera and a narrowband filter that was close to the Hydrogen Alpha transmission line. It is difficult to observe due to its extremely low brightness.

Imagers Notes: This is by far my longest capture to date, requiring 43 hours of integration time over 2 panels, 2 filters for nebulosity, and 3 for stars (Ha, Oiii nebulosity, RGB for stars). This object is fairly large and dim, spanning 6 full moons in the sky. I had a good bit of difficulty getting that much data integrated over 9 nights of imaging and had to cut the time short and process it due to weather. The individual subframes alone were over 200GB of data.
