04:42:42 Hardware GEM pier side reporting is available.
04:42:43 Initializing AcquireSupport V9.0.3
04:42:43 Weather safe, server is Boltwood Cloud Sensor II
04:42:43 User actions detected.
04:42:43 Telescope is ACP->TM61, driver V3
04:42:43 Dome is MaxDome
04:42:43 MaxIm DL is version 6.28
04:42:43 Imager is ASCOM
04:42:43 Using focus offsets and star mags from FilterInfo.txt
04:42:43 Selecting filter SG from previous ACP run at 20240618@044052 UTC
04:42:43 Imager readout modes:
04:42:43   0 is Fast
04:42:43   1 is Normal
04:42:43 Guider is SX Universal (no rotator)
04:42:43 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
04:42:43 Max unguided exposure 60 sec.
04:42:43 Guider is set to multi-star mode
04:42:43 (assuring that FocusMax is running now...)
04:42:43 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
04:42:43 Calculated field of view (arcmin): H = 36.3 V = 24.3
04:42:43 Plate solving with GSC 1.1 (ok for wider fields)
04:42:43 Mount supports tracking rate offsets
