M1 (NGC 1952)

M1 is the renowned Crab Nebula, the remnant of the supernova explosion seen in 1054, located about a degree northwest of zeta Tauri (which makes up the tip of the lower horn).

The nebula continues to expand at about 1000 km/sec. At its centre is a sixteenth-magnitude dwarf, now a pulsar.

Despite its fame the object will probably disappoint. While visible in 10x50 glasses it will only be a small hazy patch of light. You need a large telescope to get the most out of this nebula.
