- Early morning session (3.8 hours) Session operated in fully automated mode with  monitoring during the first 20 minutes.  Cloud developed in second half of session - Main aim of the session was to check AstroMain Program for any issues following recent code changes. Secondary aim was to collect image data for a number of variables stars, nearby stars and comets.   (Moon at 95% phase, ie near full)     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  6.5°C (min) before climbing later to 8°C (Dew heaters on new automated control) - CCD Temperature:  -15°C  (64% av. power) - Notes from 2019-10-15 >>
