04:59:50 Hardware GEM pier side reporting is available.
04:59:51 Initializing AcquireSupport V9.0.3
04:59:51 Weather safe, server is Boltwood Cloud Sensor II
04:59:51 Telescope is ACP->TM61, driver V3
04:59:51 Dome is MaxDome
04:59:51 MaxIm DL is version 6.28
04:59:51 Imager is ASCOM
04:59:51 Using focus offsets and star mags from FilterInfo.txt
04:59:51 Selecting filter V from previous ACP run at 20240127@045652 UTC
04:59:51 Imager readout modes:
04:59:51   0 is Fast
04:59:51   1 is Normal
04:59:51 Guider is SX Universal (no rotator)
04:59:51 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
04:59:51 Max unguided exposure 60 sec.
04:59:51 Guider is set to multi-star mode
04:59:51 (assuring that FocusMax is running now...)
04:59:51 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
04:59:51 Calculated field of view (arcmin): H = 36.3 V = 24.3
