Description

Abell 79 is a bright unusual planetary nebula in Lacerta. It is small (59 arc seconds) but with an assymetrical morphology which results in it being named "The 6 Nebula".
The Ha signal is much stronger than OIII, and has a more intricate structure. Some estimates put it at a distance of 11,360 light years whereas other estimates are 5,900 light years.
It was discovered initially by Rudolf Minkowski in 1947, although he didn't realise that it was a planetary nebula. Subsequently George Abell classified it as a planetary nebula in his catalog published in 1955.
Superresolution techniques (also known as drizzle) were used to capture the maximum detail in this small object.
