Catching the Dumbbell Nebula during the Meteor Shower

While watching the Persiad Meteor Shower Wednesday night/Thursday morning (and trying get photo with my old camera) I had another go at it with my autoguider setup (see autoguider post) imaging the the Dumbbell Nebula (M27).  The Dumbbell Nebula is a planetary nebula, formed from an exploding star 9800 years ago (estimated).  It located in the constellation Vulpecula (halfway between the bright stars,  Deneb and Altair of the Summer Triangle) at a distance of about 1360 light years from Earth.

The image was made by stacking nine exposures each 90 seconds for a total time of 14.5 minutes. The autoguider worked perfectly as the stars show no trailing.
