04:40:34 This is AcquireScheduler V9.0.3
04:40:34 Custom image file path/names are in use

04:40:34 Hardware GEM pier side reporting is available.
04:40:35 Initializing AcquireSupport V9.0.3
04:40:35 Weather safe, server is Boltwood Cloud Sensor II
04:40:35 Telescope is ACP->TM61, driver V3
04:40:35 Dome is MaxDome
04:40:35 MaxIm DL is version 6.28
04:40:35 Imager is ASCOM
04:40:35 Using focus offsets and star mags from FilterInfo.txt
04:40:35 Selecting filter V from previous ACP run at 20240213@043838 UTC
04:40:35 Imager readout modes:
04:40:35   0 is Fast
04:40:35   1 is Normal
04:40:35 Guider is SX Universal (no rotator)
04:40:35 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
04:40:35 Max unguided exposure 60 sec.
04:40:35 Guider is set to multi-star mode
04:40:35 (assuring that FocusMax is running now...)
04:40:35 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
04:40:35 Calculated field of view (arcmin): H = 36.3 V = 24.3
04:40:35 Plate solving with GSC 1.1 (ok for wider fields)
04:40:35 Mount supports tracking rate offsets
