02:44:37 Initializing AcquireSupport V9.0.3
02:44:37 Weather safe, server is Boltwood Cloud Sensor II
02:44:37 Telescope is ACP->TM61, driver V3
02:44:37 Dome is MaxDome
02:44:37 MaxIm DL is version 6.28
02:44:37 Imager is ASCOM
02:44:37 Using focus offsets and star mags from FilterInfo.txt
02:44:37 Selecting filter SU from previous ACP run at 20240128@024152 UTC
02:44:37 Imager readout modes:
02:44:37   0 is Fast
02:44:37   1 is Normal
02:44:37 Guider is SX Universal (no rotator)
02:44:37 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:44:37 Max unguided exposure 60 sec.
02:44:37 Guider is set to multi-star mode
02:44:37 (assuring that FocusMax is running now...)
02:44:37 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:44:37 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:44:37 Plate solving with GSC 1.1 (ok for wider fields)
02:44:37 Mount supports tracking rate offsets
