Messier 57

Messier 57 The popular destination of the shows is the Ring-Nebula in the constellation Lyra. It's very easy to find, it's just enough Lyra's mid-light star to set a not too large magnification binoculars. The flicker of smoke from the distance 1140 is actually 0.4 light years in diameter. Apply approx. 20,000 years ago, an old star was blown, a white dwarf stayed in place, its brightness around 14 magnitudes. The central star was photographed for the first time by Jenő Gothard in 1886 - proving that a particular instrument can be photographed with much lighter bodies than visually glimpses. Although ring-shaped fog is very easy to see, the central star is hard to catch. The ring structure of the fog is evident with all kinds of binoculars. Its internal bright areas are surrounded by a double shell of gas, its shape resembles a butterfly. This can be easily seen from a dark skies with a larger telescope.
