Picture of the Crab pulsar taken at the Leuschner Observatory by Dick Treffers, taken through a 30-inch reflector with a CCD camera equipped with a rotating wheel. The wheel spun with same frequency as the pulsar flashes: 29.9 Hertz. Each sub-image shows the pulsar at a particular phase, and took one minute of integration time. The phases proceed 45 deg from image to image in the sequence.
