My first steps with autoguiding, and my first deepsky Picture. I am happy with it, but there is a lot of space for improvement, when i see the Pictures here. But my learning curve is going up very steep :)
Composit out of 87 Pictures, 20x 5s, 20x15s , 20x 30s, 10x 60s, 10x 120s, 3x 300s, 1x 600s.
It was nearly full moon, and i dont used any filter, so exposure time with 300s was leading already to a much too bright Picture. Next time with filters
