Unfortunate Dumbbell

























Eventually clouds have vanished and despite of extremely short, summer nights I decided to put out the astro gears and shot Dumbbell. During this exposition our soccer team unfortunately lost with Chech republic in the match of all :(
Dumbbell nebula (M27) is the planetary nebula placed about 1300 light years from Earth. Due to this moderated distance its apparent diameter is significant (8 arc minutes). Central star is 13.5mag and is the largest known white dwarf with surface temperature 85000K.

Photo taken with Canon 20D (unmodded), GSO 6" F5 newtonian with GSO coma corrector. ISO800, 35x3 minutes.
