Description
M57. The creme de la creme of planetaries. It is here that the elements of carbon and nitrogen are primarily generated (oxygen is mainly from Type II supernovae). Gold and platinum (and many other elements like Uranium) are now believed to be from merging neutron stars. The nebula is roughly 2000 light years distant and (again) roughly twice the diameter of planet Jupiter. A 29.5 mins total exposure using 10s subframes. Stacked in DeepSkyStacker.
