Apart from the filter wheel thing messing me up and stopping where its not supposed to giving me the wrong color, green when it should have been red and blue when it should have been green, making flat frames was a nightmare as I had to remove the camera from the scope in between shooting light frames. I also had to contend with really bad seeing conditions when we did have a break in the clouds, so I'm not very happy with this final result.

The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. At X-ray and gamma-ray energies, the Crab is one of the strongest persistent sources in the sky.
At the center of the nebula lies the Crab Pulsar, a rotating neutron star, which emits pulses of radiation from gamma rays. The nebula was the first astronomical object identified with a historical supernova explosion.
