A planetary in the Hare

Vikas Chander from New Delhi, India

The faint planetary nebula Abell 7 in Lepus the Hare has an overall spherical appearance — the result of a dying star blowing its outer layers off into space. But deep narrowband imaging reveals complex detail in this expanding shell. For this Hα/OIII/RGB image, the photographer captured 67⅓ hours of narrowband data with a 24-inch scope.
