The Crab Nebula. The Crab is not an ideal object for a wide field scope like the RASA, so this image is heavily cropped. Clouds interrupted the imaging session, and I was only able to get 120 x 10s useable frames to stack. The Crab is a remnant of a supernova that was observed by Chinese astronomers in 1054. In the center of the nebula is the Crab pulsar. It is 20km-30km in diameter and spins at 30.2 revolutions per second, making the Crab the brightest, persistent gamma ray source in the sky.
