Description

Messier 27, the Dumbbell Nebula, in Vulpecula
(cropped for closer detail)

This is my first real attempt at using PixInsight to process decent data, not going back! M27 was an afterthought the night this was captured (2013-06-07), and I'm glad I grabbed 5 quick frames. This very bright planetary nebula is visible in binoculars even in semi light-polluted skies.
