Description

One of my goals for this winter was to image the Spaghetti Nebula (SH2-240).  I really liked the look of this target and it would certainly be a challenge to get a good image given how faint it is.  I had tried this with my color camera setup but quickly realized this would be a better job for a mono camera and narrowband filters.  

SH2-240 is a very faint Supernova remnant between the constellations Auriga and Taurus.  The nebula was discovered in 1952 at the Crimean Astrophysical Observatory using a special camera and hydrogen alpha filters.  The nebulous area is large and has an apparent diameter of 3 degrees (about 6 full moons wide).  It is estimated to be about 3000 light years from earth and an age of about 40,000 years.
