04:39:20 Hardware GEM pier side reporting is available.
04:39:22 Initializing AcquireSupport V9.0.3
04:39:22 Weather safe, server is Boltwood Cloud Sensor II
04:39:22 User actions detected.
04:39:22 Telescope is ACP->TM61, driver V3
04:39:22 Dome is MaxDome
04:39:22 MaxIm DL is version 6.28
04:39:22 Imager is ASCOM
04:39:22 Using focus offsets and star mags from FilterInfo.txt
04:39:22 Selecting filter V from previous ACP run at 20240618@043840 UTC
04:39:22 Imager readout modes:
04:39:22   0 is Fast
04:39:22   1 is Normal
04:39:22 Guider is SX Universal (no rotator)
04:39:22 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
04:39:22 Max unguided exposure 60 sec.
04:39:22 Guider is set to multi-star mode
04:39:22 (assuring that FocusMax is running now...)
04:39:22 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
04:39:22 Calculated field of view (arcmin): H = 36.3 V = 24.3
04:39:22 Plate solving with GSC 1.1 (ok for wider fields)
04:39:22 Mount supports tracking rate offsets
