03:22:35 Hardware GEM pier side reporting is available.
03:22:37 Initializing AcquireSupport V9.0.3
03:22:37 Weather safe, server is Boltwood Cloud Sensor II
03:22:37 Telescope is ACP->TM61, driver V3
03:22:37 Dome is MaxDome
03:22:37 MaxIm DL is version 6.28
03:22:37 Imager is ASCOM
03:22:37 Using focus offsets and star mags from FilterInfo.txt
03:22:37 Selecting filter B from previous ACP run at 20240224@031809 UTC
03:22:37 Imager readout modes:
03:22:37   0 is Fast
03:22:37   1 is Normal
03:22:37 Guider is SX Universal (no rotator)
03:22:37 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
03:22:37 Max unguided exposure 60 sec.
03:22:37 Guider is set to multi-star mode
03:22:37 (assuring that FocusMax is running now...)
03:22:37 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
03:22:37 Calculated field of view (arcmin): H = 36.3 V = 24.3
03:22:37 Plate solving with GSC 1.1 (ok for wider fields)
03:22:37 Mount supports tracking rate offsets
