07:57:51 Hardware GEM pier side reporting is available.
07:57:52 Initializing AcquireSupport V8.2.10
07:57:52 Weather safe, server is Boltwood Cloud Sensor II
07:57:52 Telescope is ACP->TM61, driver V3
07:57:52 Dome is MaxDome
07:57:52 MaxIm DL is version 6.20
07:57:52 Imager is QSI Universal
07:57:52 Using focus offsets and star mags from FilterInfo.txt
07:57:52 Selecting filter V from previous ACP run at 20191221@075502 UTC
07:57:52 Imager readout modes:
07:57:52   0 is Image Quality
07:57:52 Guider is SX Universal (no rotator)
07:57:52 Guider plate scale unknown, guided dither with guider pixels
07:57:52 Max unguided exposure 60 sec.
07:57:52 (assuring that FocusMax is running now...)
07:57:57 Calculated unbinned plate scales (arcsec/pix): H = 0.32 V = 0.32
07:57:57 Calculated field of view (arcmin): H = 17.8 V = 13.4
07:57:57 Plate solving with GSC 1.1 (ok for wider fields)
07:57:57 Mount supports tracking rate offsets
