Description

This was a major challenge for me at 0.68"/pixel with my ES 165 at only 2 arc minutes. My inspiration for this was shot with a 80cm f/7 AstroOptik Keller corrected cassegrain in Chili:

This faint planetary nebula, Abell 72 (PK 059+18.1) in the constellation Delphinus, is an expanding glowing shell of ionized gas ejected from an old red giant star. The beautiful object of George O. Abell's Catalog of Planetary Nebula is 5'700 ± 1150 light years from earth and about 2 light years across.
