03:29:33 Hardware GEM pier side reporting is available.
03:29:34 Initializing AcquireSupport V9.0.3
03:29:34 Weather safe, server is Boltwood Cloud Sensor II

03:29:34 Selecting filter SR from previous ACP run at 20240119@031747 UTC
03:29:34 Imager readout modes:
03:29:34   0 is Fast
03:29:34   1 is Normal
03:29:34 Guider is SX Universal (no rotator)
03:29:34 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
03:29:34 Max unguided exposure 60 sec.
03:29:34 Guider is set to multi-star mode
03:29:34 (assuring that FocusMax is running now...)
03:29:34 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
03:29:34 Calculated field of view (arcmin): H = 36.3 V = 24.3
03:29:34 Plate solving with GSC 1.1 (ok for wider fields)
03:29:34 Mount supports tracking rate offsets
