01:59:20 This is AcquireScheduler V9.0.3
01:59:20 Custom image file path/names are in use

01:59:20 Hardware GEM pier side reporting is available.
01:59:21 Initializing AcquireSupport V9.0.3
01:59:21 Weather safe, server is Boltwood Cloud Sensor II
01:59:21 Telescope is ACP->TM61, driver V3
01:59:21 Dome is MaxDome
01:59:21 MaxIm DL is version 6.28
01:59:21 Imager is ASCOM
01:59:21 Using focus offsets and star mags from FilterInfo.txt
01:59:21 Selecting filter B from previous ACP run at 20240127@015433 UTC
01:59:21 Imager readout modes:
01:59:21   0 is Fast
01:59:21   1 is Normal
01:59:21 Guider is SX Universal (no rotator)
01:59:21 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
01:59:21 Max unguided exposure 60 sec.
01:59:21 Guider is set to multi-star mode
01:59:21 (assuring that FocusMax is running now...)
01:59:21 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
01:59:21 Calculated field of view (arcmin): H = 36.3 V = 24.3
01:59:21 Plate solving with GSC 1.1 (ok for wider fields)
01:59:21 Mount supports tracking rate offsets
