02:18:24 This is AcquireScheduler V9.1.3
02:18:24 Custom image file path/names are in use

02:18:24 Hardware GEM pier side reporting is available.
02:18:25 Initializing AcquireSupport V9.2.4
02:18:25 Weather safe, server is Boltwood Cloud Sensor II
02:18:25 User actions detected.
02:18:25 Telescope is ACP->TM61, driver V3
02:18:25 Dome is MaxDome
02:18:25 MaxIm DL is version 6.28
02:18:25 Imager is ASCOM
02:18:25 Using focus offsets and star mags from FilterInfo.txt
02:18:25 Selecting filter B from previous ACP run at 20250123@021714 UTC
02:18:25 Imager readout modes:
02:18:25   0 is Fast
02:18:25   1 is Normal
02:18:25 Guider is SX Universal (no rotator)
02:18:25 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
02:18:25 Max unguided exposure 60 sec.
02:18:25 Guider is set to multi-star mode
02:18:25 (assuring that FocusMax is running now...)
02:18:32 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
02:18:32 Calculated field of view (arcmin): H = 36.3 V = 24.3
02:18:32 Plate solving with GSC 1.1 (ok for wider fields)
02:18:32 Mount supports tracking rate offsets
