Helix nebula is the closest and the brightest planetary nebula in the sky. It was discovered by Karl Ludwig Harding quite long time ago at 1824 in constellation Aquarius. This nebula is similar to Dumbbell or Ring Nebula, only it’s much bigger and bit closer – approximately 450 light-years.

I took this picture on Gavdos. This nebula was my primary target there, because in Switzerland is located not far above the horizon, therefore I would have to capture it through heavy light pollution. In the southernmost point of European continent was way upper in the sky. I was collecting the light coming from this nebula several nights and it was worth it:
