09:50:16 This is AcquireScheduler V9.1.3
09:50:16 Custom image file path/names are in use

09:50:16 Hardware GEM pier side reporting is available.
09:50:17 Initializing AcquireSupport V9.2.4
09:50:17 Weather safe, server is Boltwood Cloud Sensor II
09:50:17 Telescope is ACP->TM61, driver V3
09:50:17 Dome is MaxDome
09:50:18 MaxIm DL is version 6.28
09:50:18 Imager is ASCOM
09:50:18 Using focus offsets and star mags from FilterInfo.txt
09:50:18 Selecting filter B from previous ACP run at 20250524@094941 UTC
09:50:18 Imager readout modes:
09:50:18   0 is Fast
09:50:18   1 is Normal
09:50:18 Guider is SX Universal (no rotator)
09:50:18 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
09:50:18 Max unguided exposure 60 sec.
09:50:18 Guider is set to multi-star mode
09:50:18 (assuring that FocusMax is running now...)
09:50:25 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
09:50:25 Calculated field of view (arcmin): H = 36.3 V = 24.3
09:50:25 Plate solving with GSC 1.1 (ok for wider fields)
09:50:25 Mount supports tracking rate offsets
