UT 23:00 start of night
UT 23:00 [specpstd HD 80558] gr13
** half-wave plate stuck
** removed half-wave plate manually in dome, lost ~50min until problem identified &
resolved
UT 23:55 [std l745a]
** did not find star due to proper motion. aborted.
UT 00.00 acq OGLE-2013-SN-016
** rotated by rotator offset angle = 160° (Tried different angles manually in
telescope control, starting from parallactic rot. offset angle = 167° and moved
guide probe around until finally a guide star was found. due to several error msgs
etc. etc. this all took 50 min.)
