Crab nebula is the first discovered supernova remnant in history. It’s approximately 6500 light years from Earth and has diameter 11 light years. Letter M1 stands for first position in the catalogue of deep space objects, created by Charles Messier. This guy started to work as an assistant for French Navy astronomer Joseph Nicolas Delisle. He had lovely job – comet hunting. Almost every evening, just observing the skies would be my dream job. During year 1757 his supervisor calculated the return of Halley’s Comet. Unfortunately, or maybe fortunately, monsieur Delisle was wrong and poor Messier was observing wrong part of the sky at wrong time. However he saw something, the object which was not moving, compared to comets. He discovered Crab nebula. Later on, he pointed this telescope to other directions and created probably the most popular catalogue of amateur astronomers and astrophotographers living on northern hemisphere, containing more than 100 objects.
I am not particularly proud of the image I am showing here. Triangular stars, not fully sharp. I can do better than this. So M1, you will meet my telescope in the future again.
