Session Notes

W And - Mira Variable     Photometric Monitoring - Variables     - None   ( W And attempt failed due to centering issue )     Astrometric Monitoring - Nearby Stars     - Ross 248 (HH And), Teegardens Star

- Late Night Session (2.2 hrs duration). Clear / Cloudy skies, breeze - Session conducted as a Fully Automated Run, in which the Observatory Control Program opened the  Observatory,  built and executed an optimised Observing Plan before finally closing the Observatory at the end of the night (Session was monitored throughout due to computer and POTH.Hub stability problems) - Main aim of the session was to test autoguiding using PHD2 and 80mm APO Guidescope with autoguiding start/stop controlled by the Observatory Control Program whilst running a QSO job queue in fully automated mode. Secondary aims was to retest autofocussing routine after bug corrections,   acquire images of a selection of deep sky and variable star targets and perform further testing of fully automated observatory operations. - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding - Ambient Temperature:  11 degC (minimum) - CCD Temperature:  -10 degC (81% av. power) - Notes from 2018-08-14 >>
