Last weekend was a bright morning, seeing was not all that good, but I had a go at M57, The Ring nebula. Funny when the world around you wakes up. Started setting up at 03:00 started shooting at around 4:00. Used Vega as a guiding star, since guiding worked even when most of the stars where not there anymore.
