Image Description and Details : 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 SH2-116. 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 EdgeHD - all located at Fregenal de la Sierra in Southern Spain. Data captured between 7-21 June 2022. Scopes: APM TMB LZOS 152 Refractors and Celestron C14 Edge HD Cameras: QSI6120wsg8 and ZWO ASI1600MM Pro Mounts: 10Micron GM2000 HPS and iOptron CEM120 A total of 51 hours 30 minutes (HaOIIIRGB)
