Licensed to Arne Henden
02:20:37 This is AcquireScheduler V8.1.0
02:20:37 Custom image file path/names are in use
02:20:37   [PreFlip=300 PostFlip=120 AF=180 PU=60]
02:20:37 Hardware GEM pier side reporting is available.
02:20:38 Initializing AcquireSupport V8.1.1
02:20:39 Weather safe, server is Boltwood Cloud Sensor II
02:20:39 Telescope is ACP->ACP->TMO61, driver V3
02:20:39 Dome is MaxDome
02:20:39 MaxIm DL is version 5.24
02:20:39 Imager is QSI Universal
02:20:39 Using focus offsets and star mags from FilterInfo.txt
02:20:39 Selecting filter V from previous ACP run at 20180909@021805 UTC
02:20:39 Imager readout modes:
02:20:39   0 is Image Quality
02:20:39 Autoguiding is disabled
02:20:39 (assuring that FocusMax is running now...)
02:20:52 Calculated unbinned plate scales (arcsec/pix): H = 0.33 V = 0.33
02:20:52 Calculated field of view (arcmin): H = 18.4 V = 13.8
02:20:52 Plate solving With GSC 1.1 (ok for wider fields)
02:20:52 Mount supports tracking rate offsets
02:20:52 All-sky plate solving will be attempted when needed
02:20:52 All-sky service at nova.astrometry.net will be used
