Abell 6, also known as PK 136 +4.1, is a large and very faint planetary nebula in eastern Casseopia, close to the border with Camelopardus. In the above image, the planetary is barely recorded and is indicated below between the lines. The glow at the right-hand edge is from a 6th magnitude star just out of the field.
