08:27:47 Using focus offsets and star mags from FilterInfo.txt
08:27:47 Selecting filter SG from previous ACP run at 20250524@082604 UTC
08:27:47 Imager readout modes:
08:27:47   0 is Fast
08:27:47   1 is Normal
08:27:47 Guider is SX Universal (no rotator)
08:27:47 Guider plate scale is 0.2 arcsec/pix. Guided dither with main imager pixels
08:27:47 Max unguided exposure 60 sec.
08:27:47 Guider is set to multi-star mode
08:27:47 (assuring that FocusMax is running now...)
08:27:55 Calculated unbinned plate scales (arcsec/pix): H = 0.23 V = 0.23
08:27:55 Calculated field of view (arcmin): H = 36.3 V = 24.3
