M1 Crab nebula

It all started here. Crab nebula is the first catalogued deep space object. Charles Messier was searching for the comet (1758) but discovered his first deep space object. Crab nebula, also called Messier 1, is a supernova remnant – something like Veil nebula, but it’s much further from the Solar system – 6500 light years.

My first picture was made with pinched mirror, therefore I waited two years and captured it properly. Since I live in light polluted area, I chose narrow band filters, in order to get better contrast and composed this picture out of hydrogen alpha (red channel) and OIII (green and blue channel) narrow band pictures.


M1 Crab nebula

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.
