Arena C. - Gruppo Astrofili Catanesi, Private Observatory in Catania - ObservatoryCT
Sky-Watcher NWT 200/1000 + Atik 314L + Coma Corrector (0.9x focal reducer)
Clear Sky. OAG used. 2 data point binning. Exp time 90 sec (before binning). The last group of points (out of transit, after a small gap in the data) was taken during astronomical and nautical sunrise. As such, exposure time for those points was reduced to 45 sec.
