This image consists of 6 6 min. exposures taken on Jan. 7 from a vacant lot in Tucson. M1 is a supernova remnant located near the southern "horn" of Taurus, about 6,300 ly from Earth. It is 6x4 arc minutes in size. This is one of my first images and I was still experimenting with exposure time. I plan to re-shoot with greater exposure time, which should reveal greater detail.
According to the SEDs Data Base (http://seds.lpl.arizona.edu/messier/data2.html) Chinese astonomers observed and recorded the supernova in 1054 AD as a "guest star. The records show that the supernova was so bright that it was visible in the daylight for 23 days. The nebulous remnant was found by Charles Messier in 1758 and became the first item in his catalogue.
