Photo description / processing

About an hour of integration (which is really little for such a faint object). Tried to do dithering manually (I don’t have these fancy guide things) and ruined 1.5 hours of integration, accidentally turned off the tracking

IC 443 (also known as the Jellyfish Nebula) is a supernova remnant in the constellation Gemini, located about 5,000 light-years away. It is the result of a supernova explosion that occurred between 3,000 and 30,000 years ago. The nebula's distinctive shape, resembling a jellyfish, is formed by the interaction of the expanding supernova shockwave with surrounding interstellar material.
