11:52:18 This is AcquireScheduler V9.0.3
11:52:18 Custom image file path/names are in use

11:52:18 Hardware GEM pier side reporting is available.
11:52:19 Initializing AcquireSupport V9.0.3
11:52:19 Weather safe, server is Boltwood Cloud Sensor II
11:52:19 Telescope is ACP->TM61, driver V3
11:52:19 Dome is MaxDome
11:52:19 MaxIm DL is version 6.28
11:52:19 Imager is ASCOM
11:52:19 Using focus offsets and star mags from FilterInfo.txt
11:52:19 Selecting filter SI from previous ACP run at 20240215@115122 UTC
11:52:19 Imager readout modes:
11:52:19   0 is Fast
11:52:19   1 is Normal
11:52:19 Guider is SX Universal (no rotator)
11:52:19 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
11:52:20 Max unguided exposure 60 sec.
11:52:20 Guider is set to multi-star mode
11:52:20 (assuring that FocusMax is running now...)
11:52:20 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
11:52:20 Calculated field of view (arcmin): H = 36.3 V = 24.3
11:52:20 Plate solving with GSC 1.1 (ok for wider fields)
11:52:20 Mount supports tracking rate offsets

11:52:56   Switching from SI to SR filter for pointing exposure
11:52:56   Focus change of 20 steps required
11:52:59   (taking 10 sec. exposure, SR filter, binning = 4)
11:52:59   (using Fast readout mode)
11:52:59   (starting exposure)
11:53:16   (exposure complete)
