This is a narrowband image of M1.
The Crab Nebula or Messier object 1 is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The common name comes from William Parsons, 3rd Earl of Rosse, who observed the object and produced a drawing that looked somewhat like a crab. The nebula corresponds with a bright supernova recorded by Chinese astronomers in 1054.
The nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 6,500 light-years from Earth. It has a diameter of 11 light-years and is expanding at a rate of about 1,500 kilometers per second.
At the center of the nebula lies the Crab Pulsar, a neutron star 17–19 miles across with a spin rate of 30.2 times per second, which emits pulses of radiation from gamma rays to radio waves.
Over 25 hours of exposure.
