The Crab Nebula
The Crab Nebula (M1) is a supernova remnant in the constellation Taurus  the Bull. It has a high surface brightness, so a 3-inch telescope (and  even some binoculars) will reveal it. The object shines at magnitude  8.0. The Crab Nebula has an oval shape. It measures 6’ by 4’ and orients  northwest to southeast. The easiest way to find the Crab Nebula is to  start at the 4th-magnitude bluish star Zeta Tauri. From there, move 1°  to the northwest. (16-inch RC Optical Systems Ritchey-Chrétien reflector  at f/9, Apogee U16M CCD camera, Hydrogen-alpha/LRGB image with  exposures of 9.5, 25, 9, 9, and 9 hours, respectively)
