The Cancer Nebula (Messier 1, NGC 1952) is a supernova residue in the Taurus constellation. In 1054, Chinese and Arab astronomers were observed for a period of 23 days with the naked eye (supernatural, the remains of the Cancer Nebula). His name was derived from the fact that in the drawing drawn by Lord Rosse in 1844 he was very similar to a cancer, but when later examined with larger binoculars, he looked quite different, but by then the name of the Cancer Fog was already fixed.6500 light years away from the Earth, its diameter It grows 11 light years and 1500 km per second. Its center has a 16m bright neutron star (pulsar), which was discovered in 1968. It turns 30 times per second around its axis and emits extremely powerful radio waves. 

 Preparing the photo. Due to the winter weather, the raw material was hard to reach for the narrow strip. Seeing that I can not get out of the way to gather RGB channels in the near future I think I'm working on a 2014 Canon 450D photo. I strived for natural color, but in a sense, the narrow band channels are fake.
