- FO And, RX And, Z And, CY Aqr, TT Ari, Eps Aur, Zet Aur, CI Cyg, RZ LMi, U Mon, HX Peg, Peg RU, Per GK, FG Sge, U Sge, V Sge, WZ Sge, RR Tau, ER UMa (variables)- Barnards Star, 61 Cyg, HH And (Ross 248), Groombridge 34, Teegardens Star ( Nearby Stars)
- All night session (13.0 hrs), operated under automated telescope & camera control - Ambient Temperature 2.0 degC falling through the night to reach -2.0 degC (minimum) by dawn - CCD operation of -20 degC
(at 52% average cooling).- main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. Three time series where collected (SS Cyg, U Gem, HD189733)
- opportunity taken to acquire images of selected deep sky objects
