      Description

      Abell 31 is an ancient planetary nebula in the constellation of Cancer. It’s estimated to be about 2,000 light years away, and very large for a planetary nebula; almost as large as the better known helix nebula. Although large, it is extremely faint, requiring long exposure to capture. It also has a an interesting ‘X’ structure in the middle of it.
