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.
