Description

As I was processing an image of the Heart Nebula, I noticed what looks like a small blue abberation on one side of the field.  Initially irritated at what I assumed was a flaw in my equipment or technique, closer examination reveled the "abberation" to be a real object.  A friend quickly identified it as a planetary nebula WeBo 1. About 5,000 light years away, the planetary nebula is about 1.5 light years across.
