Imaging
2010-01-18- Evening session (4.7 hrs), cold & frosty, dew on front lens by end of session despite dew shield and dew heater - Session operated in observatory for first hour and then under semi-automated control, with remote monitoring from indoors computer. Problems encountered in last hour with wireless link to observatory laptop failing - Ambient Temperature: Initially 0 deg C, falling steadily to -3 deg C (minimum) - CCD operation -30 degC (at 66% average cooling). - main objectives of the session was to make a successful return to imaging using back up 8" LX200 scope, with primary aim of acquiring images of selected project stars for ongoing photometric and astrometric analysis - Notes from 2010-01-18
