The Crab Nebula (Messier 1) is one of my favorite objects in the sky. The nebula is the result of a bright supernova explosion recorded by Chinese astronomers in 1094. John Bevis, an English astronomer, observed it in 1731. It is the first astronomical object to be associated with a supernova. The Crab is about 6,500 light years from Earth in the Perseus Arm of our galaxy. At the center of the nebula is the Crab Pulsar, which pulses about 30 times a second.
This image was taken with the same setup as the earlier images posted from the 2.1.16 imaging session. This image is a 2-minute integration and has been heavily cropped as the Crab itself is rather small with the focal reducer in use.
The trials, tribulations and small triumphs of a Charlotte, NC astronomer imaging under Bortle 8/9 skies.
