Local crab vs. the Helix Nebula
The former is a local crab. Discovered by me and will probably only ever get a mention in its lifetime in this post. Radius around 5 cm.
The later is the Helix Nebula located 650 light-years away in constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824. (according to wikipedia). Often been refered to as the eye of the God. Radius 2.87 light years.
