Description:
Sharpless(SH)2-240, the Spaghetti Nebula, is a supernova remnant (SNR) in the Milky Way between the constellations Auriga and Taurus. It was discovered in 1952 at the Crimean Astrophysical Observatory, in what is now Ukraine, by Grigory Shajn using a camera and a narrowband filter close to the Hydrogen Alpha transmission line. The image below, a total of 6 hours of exposure time, was taken through narrow band filters in the hydrogen alpha, oxygen three and sulfur two wavelengths during the only two clear nights last week (between atmospheric rivers), using the 8 inch Newtonian telescope in our backyard observatory. The original discovery was part of a survey conducted between 1945 and 1955, using captured German equipment, as the observatory was practically destroyed during WII.
