04:35:16 Initializing AcquireSupport V9.0.3
04:35:16 Weather safe, server is Boltwood Cloud Sensor II
04:35:16 Telescope is ACP->TM61, driver V3
04:35:16 Dome is MaxDome
04:35:16 MaxIm DL is version 6.28
04:35:16 Imager is ASCOM
04:35:16 Using focus offsets and star mags from FilterInfo.txt
04:35:16 Selecting filter SU from previous ACP run at 20240219@043308 UTC
04:35:16 Imager readout modes:
04:35:16   0 is Fast
04:35:16   1 is Normal
04:35:16 Guider is SX Universal (no rotator)
04:35:16 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
04:35:16 Max unguided exposure 60 sec.
04:35:16 Guider is set to multi-star mode
04:35:16 (assuring that FocusMax is running now...)
04:35:16 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
04:35:16 Calculated field of view (arcmin): H = 36.3 V = 24.3
04:35:16 Plate solving with GSC 1.1 (ok for wider fields)
04:35:16 Mount supports tracking rate offsets
