M27 Dumbbell nebula (again, now much better)

Here's M27, the dumbbell nebula again.
It's a nebula around an exploded star, it lights up because of the radiating star in the middle.
The distance is about 1250 light years.
This picture is a composition of 60x 1Min on ISO800, shot with an eos400d in prime focus of a Newtonian telescope with aperture of 200mm and f=1000mm.
