12:54:26 Hardware GEM pier side reporting is available.
12:54:27 Initializing AcquireSupport V9.0.3
12:54:27 Weather safe, server is Boltwood Cloud Sensor II
12:54:27 Telescope is ACP->TM61, driver V3
12:54:27 Dome is MaxDome
12:54:27 MaxIm DL is version 6.28
12:54:27 Imager is ASCOM
12:54:27 Using focus offsets and star mags from FilterInfo.txt
12:54:27 Selecting filter SR from previous ACP run at 20240127@125305 UTC
12:54:27 Imager readout modes:
12:54:27   0 is Fast
12:54:27   1 is Normal
12:54:27 Guider is SX Universal (no rotator)
12:54:27 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
12:54:27 Max unguided exposure 60 sec.
12:54:27 Guider is set to multi-star mode
12:54:27 (assuring that FocusMax is running now...)
12:54:27 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
12:54:27 Calculated field of view (arcmin): H = 36.3 V = 24.3
12:54:27 Plate solving with GSC 1.1 (ok for wider fields)
12:54:27 Mount supports tracking rate offsets
