03:54:39 Initializing AcquireSupport V9.2.4
03:54:39 Weather safe, server is Boltwood Cloud Sensor II
03:54:39 User actions detected.
03:54:39 Telescope is ACP->TM61, driver V3
03:54:39 Dome is MaxDome
03:54:39 MaxIm DL is version 6.28

03:54:39 Using focus offsets and star mags from FilterInfo.txt
03:54:39 Selecting filter SI from previous ACP run at 20250115@035312 UTC
03:54:39 Imager readout modes:
03:54:39   0 is Fast
03:54:39   1 is Normal
03:54:39 Guider is SX Universal (no rotator)
03:54:39 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
03:54:39 Max unguided exposure 60 sec.
03:54:39 Guider is set to multi-star mode
03:54:39 (assuring that FocusMax is running now...)
03:54:47 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
03:54:47 Calculated field of view (arcmin): H = 36.3 V = 24.3
03:54:47 Plate solving with GSC 1.1 (ok for wider fields)
03:54:47 Mount supports tracking rate offsets
