The Crab Nebula. Messier 1

On July 4th 1054 Astronomers in China Reported a star so bright it could easily be seen during the day for 23 days.
We now know that they were witnessing a Supernova which could be seen with the naked eye for almost 2 years. The exploding star is today still travelling outwards at over 3 million miles an hour creating the beautiful Crab Nebula in the constellation of Taurus. Its now 10 light years across and 6,300 light years away. What remains of the star that exploded is called the Crab Pulsar and can be found at the centre of the nebula. Spinning at 30 times a second its now a tiny Neutron star, 1.5 times the mass of our Sun crushed into an object just 6 miles across. Can you imagine that!!!!!
I find it hard.
No longer visible to the naked eye, binoculars will reveal a small smudge but a telescope and a dslr sensor can reveal some of its beauty.
The image was taken using only 36 minutes of data with poor seeing (that's when you look up and can only see the bright stars because of the moisture etc in the air) so I will be revisiting this object when conditions are better.
