10:37:00 Initializing AcquireSupport V9.0.3
10:37:00 Weather safe, server is Boltwood Cloud Sensor II
10:37:00 Telescope is ACP->TM61, driver V3
10:37:00 Dome is MaxDome
10:37:00 MaxIm DL is version 6.28
10:37:00 Imager is ASCOM
10:37:00 Using focus offsets and star mags from FilterInfo.txt
10:37:00 Selecting filter SG from previous ACP run at 20240127@103240 UTC
10:37:00 Imager readout modes:
10:37:00   0 is Fast
10:37:00   1 is Normal
10:37:00 Guider is SX Universal (no rotator)
10:37:00 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
10:37:00 Max unguided exposure 60 sec.
10:37:00 Guider is set to multi-star mode
10:37:00 (assuring that FocusMax is running now...)
10:37:00 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
10:37:00 Calculated field of view (arcmin): H = 36.3 V = 24.3
10:37:00 Plate solving with GSC 1.1 (ok for wider fields)
10:37:00 Mount supports tracking rate offsets
