The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant in the constellation of Taurus. The now-current name is due to William Parsons, who observed the object in 1840 using a 36-inch telescope and produced a drawing that looked somewhat like a crab.[5] Corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was observed later by English astronomer John Bevis in 1731. The nebula was the first astronomical object identified with a historical supernova explosion.

What an amazing object, I imagine what it was like in 1054 when the night sky was as bright as day due the the explosion of the star that we now know as M1.

I took this in my back garden using a WO132FLT refractor and a ZWO183MM using a DarkFrame Stellardrive NEQ6 mount, this helped improve my guiding so that I could benefit from the 0.66"/pixel image scale.

The image was scaled at 1.6 in APP to help with resolution and cropping down the processing line. The image was finished off in Photoshop, (which I am still learning).
