04:48:23 Initializing AcquireSupport V9.0.3
04:48:23 Weather safe, server is Boltwood Cloud Sensor II
04:48:23 Telescope is ACP->TM61, driver V3
04:48:23 Dome is MaxDome
04:48:23 MaxIm DL is version 6.28
04:48:23 Imager is ASCOM
04:48:23 Using focus offsets and star mags from FilterInfo.txt
04:48:23 Selecting filter V from previous ACP run at 20240217@044645 UTC
04:48:23 Imager readout modes:
04:48:23   0 is Fast
04:48:23   1 is Normal
04:48:23 Guider is SX Universal (no rotator)
04:48:23 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
04:48:23 Max unguided exposure 60 sec.
04:48:23 Guider is set to multi-star mode
04:48:23 (assuring that FocusMax is running now...)
04:48:23 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
04:48:23 Calculated field of view (arcmin): H = 36.3 V = 24.3
04:48:23 Plate solving with GSC 1.1 (ok for wider fields)
04:48:23 Mount supports tracking rate offsets
