Description

The Helix Nebula (NGC 7293, Caldwell 63) is a planetary nebula around 700 light years away in the constellation of Aquarius.

According to O'Meara (2016) the nebula was discovered by Georg Friedrich Julius Arthur von Auwers in 1862. However, Wikipedia lists the discoverer as being Karl Ludwig Harding probably sometime before 1824.

The nebula is the closest planetary nebula to Earth and is around 12' x 10' in size.

The Helix was photographed between 22 August 2020 and 8 September from a rig in Spain that is privately owned and operated by Barry Wilson and me.
