IC 2973 - Spiral Galaxy with Supernovae 2011ao Photometric Monitoring - Variables - Z And, SY Cnc, R CrB, AM CVn, RS CVn, CI Cyg, S Cyg, SS Cyg, AM Her, SS Her, U Her, BL Lac, RZ LMi, SZ Lyn, CY Lyr, GK Per, ER UMa, SU UMa Astrometric Monitoring - Nearby Stars - DX Cnc, 61 Cyg, Gliese 412, Groombridge 1830, Lalande 21185
- Post midnight session (2.7 hrs), (2011-03-19) - Session operated under semi-automated control, with remote monitoring from indoors computer. - Ambient Temperature: recording failed after 50 mins when connectivity with Optec TCF-S Focuser was lost. Temperature at this points had fallen to -0.5°C. - CCD operation -30°C (at 66% average cooling). - main objectives of the session was to acquire images of selected project stars for ongoing photometric analysis.
