Sh2-240; Simeis 147; “Spaghetti Nebula”

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.[2] 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.[3]

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.[4]

This image was only created from 7 Ha, 11 Oiii, and  11 Sii images as the weather was simply not playing ball. The Oiii proved particularly hard to drawn out and used the data put decided not to bring it out as the data was to weak. I will revisit this target on a wide angle telescope like the William Optics redcat51, as only a small part of the area of the sky was captured. All told the data I had and worked on looks to be okay and shows why its called the Spaghetti Nebula. Underneath the main image is the HA image which is the strongest signal to use.
