05:17:09 Hardware GEM pier side reporting is available.
05:17:10 Initializing AcquireSupport V9.2.4
05:17:10 Weather safe, server is Boltwood Cloud Sensor II
05:17:10 Telescope is ACP->TM61, driver V3
05:17:10 Dome is MaxDome
05:17:10 MaxIm DL is version 6.28
05:17:10 Imager is ASCOM
05:17:10 Using focus offsets and star mags from FilterInfo.txt
05:17:10 Selecting filter SG from previous ACP run at 20250524@051630 UTC
05:17:10 Imager readout modes:
05:17:10   0 is Fast
05:17:10   1 is Normal
05:17:10 Guider is SX Universal (no rotator)
05:17:10 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
05:17:10 Max unguided exposure 60 sec.
05:17:10 Guider is set to multi-star mode
05:17:10 (assuring that FocusMax is running now...)
05:17:18 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
05:17:18 Calculated field of view (arcmin): H = 36.3 V = 24.3
05:17:18 Plate solving with GSC 1.1 (ok for wider fields)
05:17:18 Mount supports tracking rate offsets
