Crab Nebula - M1

This picture of the Crab Nebula was taken using Ektachrome film at the prime focus of the Kitt Peak 4-meter Mayall telescope on October 1, 1973. Although this is a simple color-film image of rather short exposure time, the Crab Pulsar is clearly visible; it is the slightly lower and more right (South-West; in this pic, 

North is up and East is left) of the two central stars of this nebula - 

the second of these stars is a foreground object projected over the nebula.
