10:17:07 This is AcquireScheduler V9.0.3
10:17:07 Custom image file path/names are in use

10:17:07 Hardware GEM pier side reporting is available.
10:17:08 Initializing AcquireSupport V9.0.3
10:17:08 Weather safe, server is Boltwood Cloud Sensor II
10:17:08 Telescope is ACP->TM61, driver V3
10:17:08 Dome is MaxDome
10:17:08 MaxIm DL is version 6.28
10:17:08 Imager is ASCOM
10:17:08 Using focus offsets and star mags from FilterInfo.txt
10:17:08 Selecting filter SI from previous ACP run at 20240223@101633 UTC
10:17:08 Imager readout modes:
10:17:08   0 is Fast
10:17:08   1 is Normal
10:17:08 Guider is SX Universal (no rotator)
10:17:08 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
10:17:08 Max unguided exposure 60 sec.
10:17:08 Guider is set to multi-star mode
10:17:08 (assuring that FocusMax is running now...)
10:17:08 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
10:17:08 Calculated field of view (arcmin): H = 36.3 V = 24.3
10:17:08 Plate solving with GSC 1.1 (ok for wider fields)
10:17:08 Mount supports tracking rate offsets
