Session Notes

Venus Mars Jupiter     Abell 1213 - Galaxy Cluster     NGC 3179 - Spiral Galaxy NGC 3184 - Spiral Galaxy (Herschel I - 168)     Photometric Monitoring - Variables - RX And, U And, FS Aur, KR Aur, CV CMi, RS CVn, RZ LMi, CN Ori, CZ Ori, FOR Ori, FU Ori, GK Per, RR Tau, SU Tau, ER UMa     Astrometric Monitoring - Nearby Stars - Groombridge 34

- Evening session (3.5 hrs duration).  - Session parts operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature: -2.5°C (minimum)  - CCD operation -30°C (at 65% average cooling).   - main objectives of the session were 1) to acquire image of Venus, Mars & Jupiter. In order to prevent oversaturation of the CCD the front of the telescope stopped down to approximately 3", using a sheet of cartridge paper with rough circular hole cut in it. 2) to acquire images of selected project stars for ongoing photometric and astrometric analysis.  -
