02:16:21 This is AcquireScheduler V9.0.3
02:16:21 Custom image file path/names are in use

02:16:21 Hardware GEM pier side reporting is available.
02:16:23 Initializing AcquireSupport V9.0.3
02:16:23 Weather safe, server is Boltwood Cloud Sensor II
02:16:23 Telescope is ACP->TM61, driver V3
02:16:23 Dome is MaxDome
02:16:23 MaxIm DL is version 6.28
02:16:23 Imager is ASCOM
02:16:23 Using focus offsets and star mags from FilterInfo.txt
02:16:23 Selecting filter B from previous ACP run at 20240222@021434 UTC
02:16:23 Imager readout modes:
02:16:23   0 is Fast
02:16:23   1 is Normal
02:16:23 Guider is SX Universal (no rotator)
02:16:23 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:16:23 Max unguided exposure 60 sec.
02:16:23 Guider is set to multi-star mode
02:16:23 (assuring that FocusMax is running now...)
02:16:23 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:16:23 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:16:23 Plate solving with GSC 1.1 (ok for wider fields)
02:16:23 Mount supports tracking rate offsets
