The Crab Nebula also known as M1 .
In 1054 Native American and Chinese astronomers recorded seeing a new star in the sky. It was actually a star going supernova. The star is about 6500 light years from earth.  In 1928 a US astronomer named edwin hubble (same guy teh telescope is named for) connected a nebula he observed to teh supernova. 
Astronomers have since discovered teh remains of teh star that blew up as a rapidly rotating neutron star called a pulsar. It rotates about 30 times second. . The neutron star itself is only about 15 miles or so in diameter but has a mass of 1.5-2.5 the sun
this is 5 hours of exposure in my backyard
