Objects Session Notes
NGC 6928 - Spiral Galaxy and adjacent galaxies 103P/Hartley - Comet Variable Stars Photometric Monitoring - Variables - R CrB, S Cyg, AM Her, U Her, FG Sge
- V Sge, WZ Sge attempts (failed due to dew)
Astrometric Monitoring - Nearby Stars - None
- Late evening session (1.8 hrs), ended prematurely due to dew (dew shield accidently left off), plus indications of deteriorating sky conditions - Session operated under semi-automated control, with remote monitoring from indoors computer. - Ambient Temperature: 7.5 deg C (minimum) - CCD operation -20 degC (at 66% average cooling). - main objectives of the session was to acquire images of selected project stars for ongoing photometric analysis. and to test a trial version of RSpec software program under live conditions -
