02:30:58 Initializing AcquireSupport V9.0.3
02:30:58 Weather safe, server is Boltwood Cloud Sensor II
02:30:58 Telescope is ACP->TM61, driver V3
02:30:58 Dome is MaxDome
02:30:58 MaxIm DL is version 6.28
02:30:58 Imager is ASCOM
02:30:58 Using focus offsets and star mags from FilterInfo.txt
02:30:58 Selecting filter B from previous ACP run at 20240328@022902 UTC
02:30:58 Imager readout modes:
02:30:58   0 is Fast
02:30:58   1 is Normal
02:30:58 Guider is SX Universal (no rotator)
02:30:58 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:30:58 Max unguided exposure 60 sec.
02:30:58 Guider is set to multi-star mode
02:30:58 (assuring that FocusMax is running now...)
02:30:58 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:30:58 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:30:58 Plate solving with GSC 1.1 (ok for wider fields)
02:30:58 Mount supports tracking rate offsets
