The Crab Nebula
I don’t see the Crab - apparently famous astronomer Lord Rosse did and thus it is named. We know its currently 973 years old as the supernova that made it occurs in 1052 in Chinese and Arab records. Its called Messier 1 as it was the object that first got in the way of Charles Messiers comet hunting. He didn’t know it at the time, but he was finding, counting and cataloguing much larger objects than comets which include these Nebulas, Star clusters and even things like other Galaxies - The Andromeda Galaxy is Messier 31 for instance.
This is an hour of 3 minutes frames in dark skies.
