Helix Nebula - details in description

NGC 7293 a.k.a. Helix Nebula

…………………………..

Helix Nebula, also known as the Eye of God, is a planetary nebula that was discovered about 200 years ago by German astronomer Karl Harding and can be found at 650 light-years from Earth, in the constellation of Aquarius. Specialists believe that Helix appeared due to a star relatively similar to the Sun, a star that reached the last stage of its existence and began to release large amounts of energy and gas in the outer space. The calculated diameter of this nebula is almost 3 light years, and the expansion speed exceeds 20 miles / sec.

In the northern hemisphere ( 45 degrees ) Helix can be observed / imaged only during the summer, August being the best month for this, but because it does not rise much in the night sky, those passionate about astrophotography and / or visual observations must use locations with a good opening towards the south, and away from the light pollution of the big cities.
