Image Details:

The Crab Nebula is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The nebula, 6,500 light-years away, is expanding at 1,100 km (700 miles) per second. I used my biggest telescope in the observatory to capture this supernova remnant, it was a very tough target to photograph because it needed a big telescope, but I was a bit lucky to capture it.
