The Crab Nebula (also known as M1) is a supernova remnant in Taurus. I find M1 interesting because it has curious shapes depending on which wavelengths of light you use to image it. To create this false color composite I used Hydrogen Alpha, Oxygen-III and Sulphur-II. I acquired the data for this image last November, but only recently managed to do the processing to make the final composite. I used CCDStack for all registration and stacking and Photoshop CS5 for the rest. Its incomparable to the image taken by the Hubble, but I'm still pleased with this result.
