Description

M57, a little bubble in the middle of nowhere... 20x120s @1600ISO without autoguiding. Once again, from my heavily light-polluted backyard. I was planning to do a little more time (at least double), but clouds showed up around 1:45. I won't make an other session on this object. It is smaller than I expected and I don't think I can get more details with my setup.
