02:23:08 This is AcquireScheduler V9.0.3
02:23:08 Custom image file path/names are in use

02:23:08 Hardware GEM pier side reporting is available.
02:23:09 Initializing AcquireSupport V9.0.3
02:23:09 Weather safe, server is Boltwood Cloud Sensor II
02:23:09 Telescope is ACP->TM61, driver V3
02:23:09 Dome is MaxDome
02:23:09 MaxIm DL is version 6.28
02:23:09 Imager is ASCOM
02:23:09 Using focus offsets and star mags from FilterInfo.txt
02:23:09 Selecting filter B from previous ACP run at 20240213@021549 UTC
02:23:09 Imager readout modes:
02:23:09   0 is Fast
02:23:09   1 is Normal
02:23:09 Guider is SX Universal (no rotator)
02:23:09 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:23:09 Max unguided exposure 60 sec.
02:23:09 Guider is set to multi-star mode
02:23:09 (assuring that FocusMax is running now...)
02:23:09 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:23:09 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:23:09 Plate solving with GSC 1.1 (ok for wider fields)
02:23:09 Mount supports tracking rate offsets
