Abell 71
Abell 71 is a faint planetary nebula in the constellation Cygnus. It has a diameter of 168 arc seconds and is 2,400 light years from Earth. The background nebulosity is part of SH2-115.
This was a joint project with my good friend Sven Eklund, with data captured on both my dual rig of 6" refractors and his C14 Edge HD - all located at Fregenal de la Sierra in Southern Spain.
