Licensed to Arne Henden
02:22:16 This is AcquireScheduler V8.1.0
02:22:16 Custom image file path/names are in use
02:22:16   [PreFlip=300 PostFlip=120 AF=180 PU=60]
02:22:16 Hardware GEM pier side reporting is available.
02:22:17 Initializing AcquireSupport V8.1.1
02:22:17 Weather safe, server is Boltwood Cloud Sensor II
02:22:17 Telescope is ACP->ACP->TMO61, driver V3
02:22:18 Dome is MaxDome
02:22:18 MaxIm DL is version 5.24
02:22:18 Imager is QSI Universal
02:22:18 Using focus offsets and star mags from FilterInfo.txt
02:22:18 Selecting filter B from previous ACP run at 20190208@022114 UTC
02:22:18 Imager readout modes:
02:22:18   0 is Image Quality
02:22:18 Guider is SX Universal (no rotator)
02:22:18 Guider plate scale unknown, guided dither with guider pixels
02:22:18 Max unguided exposure 60 sec.
02:22:18 (assuring that FocusMax is running now...)
02:22:28 Calculated unbinned plate scales (arcsec/pix): H = 0.33 V = 0.33
02:22:28 Calculated field of view (arcmin): H = 18.4 V = 13.8
02:22:28 Plate solving With GSC 1.1 (ok for wider fields)
02:22:28 Mount supports tracking rate offsets
02:22:28 All-sky plate solving will be attempted when needed
02:22:28 All-sky service at nova.astrometry.net will be used
